Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bolts or pawl structures are used to fix the plastic frame and front frame together, then the assembly is secure and reliable, but the assembling time increases and labor costs increase
Solution Approach 1:
The resilient elements are designed to automatically clamp and retain the front frame through elastic deformation, eliminating the need for external fastening operations. The structure serves itself by using the inherent elasticity of the material to achieve both security and speed.
Solution Approach 2:
The patent replaces the traditional mechanical fastening system (bolts or pawls) with an elastic retention system. The resilient elements use elastic deformation to create clamping force, substituting complex mechanical fastening operations with a simpler elastic mechanism.
2Reliability
If bolts or pawl structures are used to fix the plastic frame and front frame together, then the assembly is secure and reliable, but the manufacturing operation becomes complicated and costs increase
Solution Approach 1:
The resilient elements are integrated directly into the plastic frame structure, merging the fastening function with the structural component. This eliminates the need for separate fastening parts and simplifies the manufacturing process while maintaining assembly security.
Solution Approach 2:
The integrated resilient elements automatically perform the fastening function through elastic deformation, eliminating the need for complex manual or mechanical fastening operations. The structure serves itself by using the inherent elasticity of the material to achieve both security and speed.
3Reliability
If complex fastening structures are used, then the front frame can be securely retained, but the material usage and manufacturing cost increase
Solution Approach 1:
The patent uses flexible resilient elements that can be formed as thin, lightweight structures. These flexible elements provide sufficient clamping force through elastic deformation while using minimal material compared to rigid fastening structures like bolts or pawls.
Solution Approach 2:
The resilient elements utilize elastic deformation parameters to achieve retention. By changing the physical state of the material from rigid to elastic, the system achieves secure retention with reduced material usage, as the elastic properties provide the necessary clamping force without requiring thick or heavy structures.
