It is possible to develop solutions using TRIZ tools that users are familiar with. The stowage space proposed within the front landing gear door can be wired to indicate that a cover has been properly secured and is no longer on the ports. The concept of innovation in the large is different. Then consider the external and internal interactions within the reference. It may need to be drilled down from the system level to the sub-system level to the component and function level and finally the parameter level. A technique like 9 windows can be better understood with examples and the one below from triz journal explores mobile phone as a system and ideates to find the future system, sub-system and super-system.

Under conditions of extreme stress, the captain was able to return within 40 miles of Lima at a steady height of 1600 feet by relying on the radar altimeter. Sustained innovation: the chained-germination of ideas, beginning at any point of interest and migrating upward toward the super system. More... 5. A systemity is taken into account by using the following laws: Completeness and abundance of a system. This SV is also based on EV3; however, it employs an entirely different approach. A system The system structure diagram by TRIZ Solving the contradiction in the system and between the systems should have the total view, should follow the following two principles: 1. You may be able to follow the steps of improving and resolving the current speed sensoring system. 2 Dux Diligens, Mexico. The SV is the output of the innovation exercise and is the in-process form of an innovation, something between the idea and the commercialized form of the innovation. Ideality I can’t think of anything finer. Independent verification was sought from the Lima air traffic control radar, which acknowledged the plane’s position and confirmed its height at 8000 feet (ironically a value received from the aircraft’s erroneous transponder). Laser interferometer systems may be adapted for this purpose. Any system is a subsystem of more general super-system. This is not critical as other more precise methods are available during take-off. EV1: Susceptibility to blockage through ingestion or icing(a maintenance and design issue). The … It provides specific sequential steps for developing a solution for complex problems. This is an important concept which needs elaboration. SV9: Use ram air (dynamic air pressure to increase engine power) with pebbled surface around port opening. Unexpected outcomes that emerge from the exercise as a result of serendipity, What assumptions are made at the inception, What directions for investigation are adopted, What knowledge base is initially available, What additional resources can be used, in due course, to bridge the knowledge-gap. The original basis for launching the innovation exercise has been eliminated by using functional streams as it begins to migrate toward SVs for the super-system. Global positioning system technology is commonplace and continues to evolve at a fast pace. The time period for the past and present can be defined by the user based on the context of the system/problem. The one exception is that some sub-components must be retained and cannot be modified or replaced for technology or legacy reasons. The second step is to consider other more simplified ways to deliver this main useful (value added) function by first looking within the system and if this fails by looking at other technological systems that can provide the same function but not having the disadvantages of the first system. To this problem they applied TRIZ; functional analysis, trends and evolutionary potential analysis, super-system perspective of the machine, and evolutionary potential analysis of the business model. Resolving Contradictions with 40 Inventive Principles, Playing TRIZ (Volume 2) – More Games and Cases Fostering Inventiveness, Oxford Creativity achieves global sales on lockdown learning, helping to problem solve pandemic. The goal is to improve flight safety and to fly continually optimized profiles with dynamic updates based on weather conditions as to conserve flight time and fuel consumption. Sub-system and component resources: Use raw (as found), combine together, or modify. This SV provides a pivoting cover arrangement with an independent actuator that is deployed upon engine start. Each aircraft was designed and equipped to cope with almost all conceivable flight conditions. These series of SVs also remove the need for pitot probes, static ports and associated internal tubing of the circuit. SV1: Directed light source located within static port. System minimum modification principle: as much as possible existing resources of To this problem they applied TRIZ; functional analysis, trends and evolutionary potential analysis, super-system perspective of the machine, and evolutionary potential analysis of the business model. Au début des téléphones portables, bien peu de fonctions étaient intégrées. The engine start sequence can then be activated (Figure 16). Introduction Problem solving could be described through the systemic approach. The benefit of SV22 lies in the fact that the skin panels are made to perform two entirely separate and unrelated tasks, simultaneously, without functional interference. Establishing momentum early in the innovation exercise and feeding it off early successes is crucial.2 It is also vital to give the right direction to this momentum. Ceci se produit lorsque le système ne peut plus évoluer par lui-même. This is a simple, passive SV to detect the presence of any obstruction or tape covering the static ports at night. Outils TRIZ dont la matrice, ses contradictions, ses caractéristiques et principes. 2. Loi suivante. TRIZ principles teach us that super-systems absorb their sub-systems over time. Length of moving object. 3.2. mZ���KR��Sb( Reassured by the independent verification, the flight crew started the descent in darkness. The SSA is based on knowledge abstractions that encapsulate what is known about the system of interest along specific paths of inquiry. (aka Higher-level system) Courtesy of: Victor Fey. Thus, all available resources of supersystem, base system and the subsystems are taken as "resources" of the system. Systematic design and engineering is another essential area best exemplified by the work of German systems engineering experts Gerhard Pahl and Wolfgang Beitz where systematic approaches were used to achieve efficiencies in the field of engineering design.9, The Theory of Inventive Problem Solving has an extensive suite of idea generation tools which are deployed to suit any task.1 This flexibility transfers the responsibility for planning and structuring and its successful execution onto the user. H�|S���0��s�-%6�j�K{�"�Ԫ+�]wI�'����m���H�ffޛ�f8&�W�CV,� ſ4��Y*UA�$ǤLY��U�� �s���x�0�3y�e)S�B\�,�%DX��T@� Solution vector (SV): the in-process state of an innovation and the outcome of processing the functional stream. This SV relies on monitoring decay of a low-pressure air pulse within the circuit. An individual can take a snapshot in time of the activities and make exit/entry decisions. SV17: Special water repellent baffle (device that regulates flow) installed over port. In TRIZ the suggestion is to consider using freely available resources first and then try to achieve solutions where the desired result is achieved. %PDF-1.4 %���� For this reason SSA can be used alternately as an innovation add-on to systems engineering; or as a structuring and planning add-on to innovation tools such as TRIZ. Weight of moving object . The chartered aircraft had been sitting unattended on the tarmac for several days prior to the flight. The application of the SSA is demonstrated in an ongoing issue in airline safety where several unique innovative concepts have been generated. Airbus airliners come equipped with dedicated port covers. SV12: Use ram air with heated skin panel around port opening. While the original tape removal problem was solved by the airline industry through root cause analysis, recurrences (in March 2006, March 2009 and July 2009) indicate a need for further work in the general airspeed sensor area. Differential or augmented systems have resolutions of 1m-2m. Of the 135 occupants, there were 50 injuries and nine deaths, including four of Boeing’s engineers. There is little purpose in expending valuable resources for developing concepts that will be bypassed or made redundant by others. Patterns of evolution of technical system (TS) are at the heart of TRIZ innovation technology. For innovatively improving a technical system, TRIZ advises engineers to functionally analyze the system and to focus the attention onto the essencial part of the system. Systems engineering is a team effort with a structured development process from concept to production to operation that ensures a customer’s needs are met through a system’s life cycle. To break the adhesive bond, consider a pebbled stainless plate forming the exterior of the static port as in SV9. The following is further analysis of entry vectors: EV1, EV2 and EV3 at the micro level to derive four functional streams from each of the EVs. H��T���0��>�!S���}LԦ�$��S��z���*������� SV23: Use ionized air pulsing to measure airflow. An important issue in the processing of EVs is the mandatory requirement to continually vary the field of interest (or depth-of-field) from the artifact toward the super-system. The pitot tubes, static ports and all internal tubing can be dispensed and are removed. For example: SVs 1-5 and 9-12 can be bypassed by gains in: SVs 21-24, which can be bypassed by advances in: SVs 25 and 26. As shown in Figure 17, EVs are the vehicle for innovation planning at the macro level. Bons de réduction. The functional streams provide the structuring at the micro level. Fermer . ), An almost identical accident took place only seven months prior on February 6, 1996 when another Boeing 757-225 (registration TC-GEN), operated as a charter flight by Birgenair, crashed into the ocean at night soon after take-off.4. 0000003480 00000 n The super stream augmented approach (SSA) is proposed as a planning and structuring layer to enhance the application of Theory of Inventive Problem Solving (TRIZ) tools for sustained innovation. More... 5. If the original cover were left on at night, the original problem returns. On March 5, 2009 it was reported that the likely cause of the crash of Turkish Airlines Boeing 737-800 at Schiphol, Amsterdam was a faulty altimeter. A mature innovation program in an organization is one that has several projects completed or in the pipeline. super system enables to increase flow more than 5S can provide. The first version of ARIZ was developed in 1968 and many modifications during the next 20 years received. j5���������;��z�lI r�-Ф��Q��l�NE�G]T�4���:ul-�����8�Mΐ�OÉ;�dp�c��xf This shows the capabilities of TRIZ in a wide range of problems, from near-term, fine detail problems through to longer-term technology direction and high level business strategy issues. Super-system. The EV3 is directed at improving situational awareness in the cockpit. The tool asks the evaluator to select what changes he/she is seeing in the specific patent versus the prior art. TRIZ is defined as a problem-solving analysis and forecasting tool developed by Genrich … endstream endobj 24 0 obj<>stream As a remedy to covering the static holes problem (issued in 1998) Boeing recommended that maintenance personnel should place one end of a three-foot piece of orange barricade tape over the static port and secure the orange barricade tape with yellow vinyl adhesive tape. Based on … II. In TRIZ, in addition to the concept of the Ideal Final Result, we also consider the concept of sub-system and super-system related to our problem. In order to escape the original defined boundaries of the system consider the task from the perspective of the super-system or its super-system looking inward at the original problem. Hyper U, Super U, U express. • Completeness and minima Innovation, super stream augmented approach (SSA), TRIZ, innovation planning, aviation safety, entry vector (EV), functional streams (FS), solution vector (SV), solvecs, sustained innovation. In 2008, the Sydney Morning Herald reported that between January and March 2006, five Qantas A330 Airbus flights had to abort take-off due to wasp-related blockages of the pitot-static system.12 In one case the turnaround time (on ground, time between flights) was less than one hour. Reference: The advantage of this SV (from the TRIZ viewpoint) is the existing resources are used to perform additional functions. In rare cases, it may perform all of the functions of the job. Possibilities within this SV include water repellent baffle covers over the static port, wire-gauze netting covers, thin criss-crossing wires with high-voltage capacitative charge, etc. The SSA approach inter-weaves concepts taken from TRIZ and Systems Engineering. endstream endobj 29 0 obj<>stream The following two SVs propose extending the use of navigation technologies developed for defense purposes toward civil aviation. 1. By tagging each cover with a radio frequency identification device (RFID) chip and having a sensor built into the receptacle space, SV8 ensures that the possibility of error or mischief is greatly reduced. Interesting new developments have been reported, including that of the BRIGHT process in the United Kingdom (UK).13 Hybrid-reasoning is a powerful and efficient approach in discursive problem solving and it is the approach used in the development of the SSA. Super System Transition Act : A system can merge with other systems or super systems. The second step is to consider other more simplified ways to deliver this main useful (value added) function by first looking within the system and if this fails by looking at other technological systems that can provide the same function but not having the disadvantages of the first system. We have to look at the system in the context of its development. This information can be used by the onboard flight computers to prevent engine start, unless the situation is corrected by the ground engineers (TRIZ standard solution 4.1.1 self-regulating system, no need for measurement). TRIZ-Philosophy Value Chain System Super-System System Vertical Intelligence Horizontal Intelligence Alternatives Sub-System System Technical System Super-System Sub-System Super-System Sub-System-System Theory Morphology Function Function Function System X X X X Explorative and system-specific TechnologyRoadMap Evolution Figure 4: Approach of TRIZ -based … Fig. TRIZ Textbooks: CID Course for Children, 1-1W2: Topic 2: Where is this or that located? Économisez sur des grandes marques avec votre CARTE U. L'ESPACE JEUX. 9 Windows – Example. As the scope of this functional stream covers the majority of sub-components within the EV, it is referred to as such. This provides a micro level analysis of solutions. System features: Size, shape, colour, transparency, weight, roughness, density, porosity, and so on. The flight crew tried to recover by initiating a climb but as the right wing of the plane rose, the left wing dropped and its wingtip caught the waves. Some of the most important ones are: • Evolution or life cycle of a TS. Emergency braking during one of the aborted take-offs caused six of eight landing gear tires to burst on the runway. SV19: Ultra high frequency (UHF) antenna on landing gear door to block port when landing gear down. The objective is to directly obtain air pressure and dynamic air pressure data from the ambient airflow. endstream endobj 25 0 obj<>stream Eight Trends of Technical Evolution . Any such modification at the entry and exit to the pitot-static circuit will require recalibration of the data, which in digital form is much easier than in the older analog versions. Special polymer panels are mounted flush with the exterior skin to register dynamic air pressure for SV21. The reason for using the term “minor” is that the scope of changes allowed is of a minor nature and is limited to a small portion of the constituents of the EV. For innovatively improving a technical system, TRIZ advises engineers to functionally analyze the system and to focus the attention onto the essencial part of the system. Lutz Schonfeld, Wikimedia Commons. When we have a system to analyse, we use 9 boxes to set the system context, define its environment (super-system) and all the details (subsystems). Keywords: TRIZ, system models, problem formulation 1. SV25: Use ground mapping radar with digital terrain matching. The author begins building innovation momentum with the air safety issue of adhesive tape removal. Three aspects of sustained innovation are of interest in industrial and commercial settings: This paper demonstrates a planning approach to assist with the systematic application of TRIZ for sustained innovation. 39 Parameters of TRIZ. super-system, the system and subs ystem in order to ensure that the derived solution does not create any problem for the super-system or sub-s ystems. TRIZ and Services Innovation 2.1. EV2: Improvements to reliability, fail-safe operation mode (a product improvement issue). For this reason SSA can be used alternately as an innovation add-on to systems engineering; or as a structuring and planning add-on to innovation tools such as TRIZ. The separation of the paths of inquiry allows the modelling of multiple … The major change is a modified form of transducers that are relocated to the exterior of the aircraft. System / Sub-system / Super-system Jack Hipple Last month we discussed how using TRIZ in management and organizational problem solving can be a bit more complicated because the definition of the "ideal" result can become complicated by the views of different people and their motives and incentives. 0 [ R=M� �>���EQ�#���gvvv��+������*|҂2P�1E��&�D+d��@�ֵ�)AC���pm ��0�H��ZÂT�נĢ>�C݌`�A���7����Q"��H�� G���/�L'O���p3�z�]���cL��J���Y�SC/O�͹�$����-�������hۗ�|)�w��Hp��J This would provide not only position, altitude and velocity information but also the roll, pitch and yaw components of the aircraft’s altitude. It will be noticed that the super-system includes the tool and the object of the … Referring to the Contradiction Matrix, the model of solution is determined based on Specific Inventive Principles. SV22: Instrument external metal skin panels to register dynamic air pressure. Efficient innovation: results from the maximal use of resources that are often freely and readily available and by the conversion of constraints into opportunities. The time period for the past and present can be defined by the user based on the context of the system/problem. endstream endobj 28 0 obj<>stream More... 3. Eight Trends of Technical Evolution . Thus, a network of solutions and various levels is derived.
