TRIZ Problem Solving: Design of Hammer

TRIZ Problem Solving Design of shape gipThis project introduced innovation in a concept invention of spurt which is a neb apply to blow (a abrupt impact) to an object. Some skillful contradictions occurred in the design, which made it difficult to find a solution draw off compromise. When TRIZ was apply in the design, things seemed to get easier. A surprising and almost entire solution was found, and finally it was put into practice smoothly.IntroductionA throb is a tool that delivers a blow (a sudden impact) to an object. A mallet is basically a force amplifier that courses by converting mechanical work into kinetic energy and back. Most quids ar hand tools using upd to take away nails, live parts, forge metal, and break apart objects. Hammers vary in shape, size, and structure, depending on their purposes. Hammers argon basic tools in numerous trades. The usual features ar a top dog (most often made of steel) and a wish (also called a haft or haft). A tralat itious hand-held hammer consists of a give interrogative and a handle, fastened together by center of a special wedge made for the purpose, or by glue, or both. This lounge suit design is often used, to combine a dense metallic great head with a non-metallic mechanical-shock-absorbing handle. Some hammers are one-piece designs made principally of a single material. A one-piece metallic hammer whitethorn optionally have its handle coated or wrapped in a resilient material such as rubber. bearingivesTo innovate the design of a hammer to make it more efficient using TRIZ hassle solving.To minimize the cost used to buy hammer using TRIZ task solving.To improve the components of hammer to contract space consumption by TRIZ chore solving.Problem Statement For years, workers have been struggling to bring assorted quality of tools to their worksite. One of the chief(prenominal) tool used by the construction workers are the hammer. A Hammer is a mechanical tool that delivers a su dden impact to an object. The essential part of hammer is head, a compact warm mass that is able to deliver the blow to the intended 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 contrasting subjects of hammers in use, they vary in shape, size and structure. Such hammers are traditional curved claw hammer and Drywall hammer. traditionalistic claw hammer are used to drives nails well and removes nails easily with the rocking action of its curved claw term Drywall hammer chops errant bits of drywall and sets nails without breaking through walls paper faces. Hammers are categorize as a heavy lineament tool thus creating difficulty for the workers to bring many types of hammer to their worksite.InconvenientVariety in the list of hammer needed to cut in a certain type of work causes difficulties to the workers in bringing it to their work site. As we already know, for each one hammer has its own work on. Hence, workers need to bring each of the type of hammer to complete their project. If it is improved it rump ease the workers job in bringing different type of hammer without overpowering 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 spent to buy each type of hammer. Thus the total cost of project give be increased gradually. Buying less number of hammer with the same operating(a) 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 paradox which is in storing it. Each hammer requires a abundant size of storage space to be stored and with the variety type of hammer, the ineluctably for bigger size storage increases with the number of hammer. If less spaces are u sed to store this tool, more other tool can be used to fill the empty spaces. This increases the compatibility of the hammer.Function analysis Subject (Tool)FunctionObject Hand secure dish out (Wood) handgrip (Wood) hold offHammer head Hammer head charge hookComponent AnalysisTRIZ toolsSegmentation (1)Divide an object into free-living partMake an object easy to assemble and disassembleThe head and the handle of the hammer can be tie ined and removed freely by user.The thread on the handle ease the user to connect the handle and the hammer head by twisting the head in a clockwise direction.Function AnalysisSubject (Tool)FunctionObjectHandHold finagle (Steel)Handle (Thread)HoldTraditional curving 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)HitNa ilComponent AnalysisContradictionThe feature that we want to improve is the expertness 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 involved material as the handle. The composite material that we have chosen is graphite fiber reinforced epoxy. This type of handle offers a blend of stiffness, lightweight and durability. These handle also inclose in a high polycarbonate resin. The addition 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 hyaloplasm (1 to 14)Weight of contemptible objectWeight of non contemptible object aloofness of moving objectLength of nonmoving object compass of moving object123451Weight of moving object+15, 8, 29,34 29, 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, 1511Stress 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 composing21, 35, 2, 3926, 39, 1, 4013, 15, 1, 28372, 11, 1314 might1, 8, 40, 1540, 26, 27, 11, 15, 8, 3515, 14, 28, 263, 34, 40, 2940-Composite Material, 26-Copying, 27-Cheap Short brio 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 puzzle out 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, fill in up with a solution for the related 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 fi nal solution that have been analyzed is by producing an standardized hammer head with graphite fiber reinforced 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/ obligate/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
