TRIZ Problem Solving: Design of Hammer

TRIZ Problem Solving Design of malleusAbstractThis project introduced innovation in a concept design of form which is a animal apply to blow (a sudden impact) to an target. Some technical contradictions occurred in the design, which made it difficult to find a solution except compromise. When TRIZ was used in the design, things seemed to get easier. A surprising and almost perfect solution was found, and finally it was put into practice smoothly.IntroductionA dick is a in any casel that delivers a blow (a sudden impact) to an tendency. A hammer is basically a force amplifier that works by converting automatic work into kinetic energy and back. to the highest degree hammers be hand tools used to drive nails, fit parts, forge metal, and break apart objects. Hammers vary in shape, size, and structure, depending on their purposes. Hammers are basic tools in some trades. The usual features are a head (most often made of steel) and a cargo area (also called a helve or haft). A traditional hand-held hammer consists of a separate head and a handle, fastened together by means of a special wedge made for the purpose, or by glue, or both. This two-piece design is often used, to combine a dense metallic striking head with a non-metallic mechanical-shock-absorbing handle. Some hammers are one-piece designs made earlier of a single material. A one-piece metallic hammer may optionally wee-wee its handle coated or wrapped in a resilient material such as rubber.ObjectivesTo innovate the design of a hammer to make it more(prenominal) efficient using TRIZ line solving.To minimize the make up used to buy hammer using TRIZ problem solving.To improve the components of hammer to reduce space consumption by TRIZ problem solving.Problem Statement For years, workers live with been struggling to roleplay different type of tools to their worksite. One of the main tool used by the construction workers are the hammer. A Hammer is a mechanical tool that delivers a sudde n impact to an object. The essential part of hammer is head, a compact solid mass that is able to deliver the blow to the mean target without itself deforming and a handle, the part where the user hold the hammer. Commonly, hammers are used to drive nails, fit parts, forge metal and break apart objects. There are different types of hammers in use, they vary in shape, size and structure. Such hammers are traditional curved claw hammer and Drywall hammer. conventional claw hammer are used to drives nails well and removes nails easily with the rocking action of its curved claw while Drywall hammer chops errant bits of drywall and sets nails without breaking through walls paper faces. Hammers are categorized as a heavy type tool thus creating problem for the workers to bring many types of hammer to their worksite.InconvenientVariety in the number of hammer require to complete in a certain type of work causes difficulties to the workers in bringing it to their worksite. As we already know, each hammer has its own function. Hence, workers need to bring each of the type of hammer to complete their project. If it is improved it can ease the workers job in bringing different type of hammer without devour too much energy.CostlyWorkers are forced to buy each type of hammer so that they can accomplish their job. This causes extra money to be dog-tired to buy each type of hammer. Thus the total cost of project will be increased gradually. Buying less number of hammer with the uniform functional would causes the cost to be decreased significantly. This would give the advantage to worker as it will cut the cost to buy a hammer.Space consumingThe average size of a hammer is bigger than other tool creates a problem which is in storing it. Each hammer requires a huge size of storage space to be stored and with the variety type of hammer, the needs for bigger size storage increases with the number of hammer. If less spaces are used to store this tool, more other tool can b e used to fill the empty spaces. This increases the compatibility of the hammer.Function abridgment Subject (Tool)FunctionObject Hand stick to palm (Wood) Handle (Wood) HoldHammer head Hammer headHitNail dowery AnalysisTRIZ toolsSegmentation (1)Divide an object into independent partMake an object easy to assemble and disassembleThe head and the handle of the hammer can be connected and removed freely by user.The thread on the handle ease the user to connect the handle and the hammer head by kink the head in a clockwise direction.Function AnalysisSubject (Tool)FunctionObjectHandHoldHandle (Steel)Handle (Thread)Hold handed-down Curved Claw (Thread)Traditional Curved Claw (Thread)HitNailHandle (thread)HoldDrywall Hammer (Thread)Drywall Hammer (Thread)HitNailHandle (Thread)HoldBody Mechanics Hammer (Thread)Body Mechanics Hammer (Thread)HitNailHandle (Thread)HoldToolmakers Hammer (Thread)Toolmakers Hammer (Thread)HitNailComponent AnalysisContradictionThe feature that we want to improve is the strength of the handle by using steel. However the drawback of using steel as a handle is it is very heavy. So by using 39 parameters matrix, we have decided to choose composite material as the handle. The composite material that we have elect is graphite fiber reinforced epoxy. This type of handle offers a blend of stiffness, lightweight and durability. These handle also encased in a high polycarbonate resin. The rundown of this material around the handle increase shock absorption, improves chemical resistance and offers protection against accidential overstrike thus reduce handle failure.Wooden Handle Steel Handle Composite HandleWooden Handle Steel HandleComposite HandlePartial Triz Contradiction Matrix (1 to 14)Weight of moving objectWeight of stationary objectLength of moving objectLength of stationary objectArea of moving object123451Weight of moving object+15, 8, 29,3429, 17, 38, 342Weight of stationary object+10, 1, 29, 353Length of moving object8, 15, 29, 34+15, 17 , 44Length of stationary object35, 28, 40, 29+5Area of moving object2, 17, 29, 414, 15, 18, 4+6Area of stationary object30, 2, 14, 1826, 7, 9, 397Volume of moving object2, 26, 29, 401, 7, 4, 351, 7, 4, 178Volume of stationary object35, 10, 19, 1419, 1435, 8, 2, 149Speed2, 28, 13, 3813, 14, 829, 30, 3410Force (Intensity)8, 1, 37, 1818, 13, 1, 2817, 19, 9, 3628, 1019, 10, 1511 stock or pressure10, 36, 37, 4013, 29, 10, 1835, 10, 3635, 1, 14, 1610, 15, 36, 2812Shape8, 10, 29, 4015, 10, 26, 329, 34, 5, 413, 14, 10, 75, 34, 4, 1013Stability of the objects composition21, 35, 2, 3926, 39, 1, 4013, 15, 1, 28372, 11, 1314Strength1, 8, 40, 1540, 26, 27, 11, 15, 8, 3515, 14, 28, 263, 34, 40, 2940-Composite Material, 26-Copying, 27-Cheap dead Living Object, 1-SegmentationFunction AnalysisSubject (Tool)FunctionObjectHandHoldHandle (Composite Material)Handle (thread)HoldTraditional Curved Claw (Thread)Traditional Curved Claw (Thread)HitNailHandle (thread)HoldDrywall Hammer (Thread)Drywall Hammer (Thread)HitNailHandle (thread)HoldBody Mechanics Hammer (Thread)Body Mechanics Hammer (Thread)HitNailHandle (thread)HoldToolmakers Hammer (Thread)Toolmakers Hammer (Thread)HitNailComponent AnalysisConclusionAs conclusion, problem in reality can be practically solved using TRIZ problem solving technique. TRIZ technique use the process of abstraction as it main way to solve problem. This means that we need to use TRIZ to determine problem, improving feature, and impact feature and lastly, come up with a solution for the colligate problem. There are many type of TRIZ process that are available for solving problem. However, for this problem the function analysis tool, the 39 parameters and 40 inventive principles is used. We have concluded that the main problems of a hammer are inconvenient, costly, and space consuming. All of the problems are solved by applying TRIZ technique. The final solution that have been analyzed is by producing an exchangeable hammer head with graphite fiber r einforced epoxy handle. This will encounter all of the problems of the common hammer. So, it can be concluded that TRIZ problem solving can be used to problem better and efficiently.Referenceshttp//me-mechanicalengineering.com/different-types-of-hammers/http//www.innovation-triz.com/http//www.triz.org/https//www.mindtools.com/pages/article/newCT_92.htmhttp//creatingminds.org/tools/triz/triz_contradiction_analysis.htmhttps//en.wikipedia.org/wiki/TRIZhttp//www.triz-journal.com/http//www.mytriz.com.my/http//www.mindtools.com/pages/article/newCT_92.htmhttp//www.triz40.com/aff_Principles_TRIZ.php
