Component Fastening by Using Snap-On Tools Replacing Traditional Fasteners

Abstract

The traditional fasteners connect the next part in different assemblies with the help of bolt, nuts and other fasteners. But main problem starts when motion passes through the assemblies; it may make the assemblies weak due to improper fastening or sometimes motion is that much rapid that it makes these fasteners weak from the joints. Because of that, the assembly may get disassembled and may damage other parts and leads to catastrophic failure. Another problem considering tightening & loosening of fasteners takes too much time; whereas Snap fits are the tools which make assembly easy to maintain and provide ease of unlocking which saves the time for production. In this research, by using the design of X concept which suggests replacing screw-nut type fasteners with Snap fits in DFA approach. So here, the main aim is to replace fasteners with modern Snap-on tools which secure high strength to withstand desired motions and emphasizing on ease of locking and unlocking with snapping by improving stress criterions. So having said that, with the use of some quality parameters in design for making this type of modern tools and put them into the production process for increasing efficiency and life of the mechanical components.
