Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional stirrup assembly methods are used, then the stirrup can be assembled, but the structure is greatly weakened during assembly
Solution Approach 1:
The stirrup is divided into separate modular components (side arms, support arms, bench element, safety arm) that can be assembled without compromising the integrity of individual parts. The reinforcement core is also segmented to match the modular structure, allowing assembly while maintaining strength.
Solution Approach 2:
The stirrup combines polymeric materials for the frame components with a metallic reinforcement core embedded within the polymeric material. This composite structure provides both the ease of assembly associated with polymers and the structural strength of metal, resolving the contradiction between manufacturability and strength.
2Productivity
If conventional stirrup assembly methods are used, then the stirrup can be assembled, but the assembly process is extremely laborious
Solution Approach 1:
The stirrup is divided into separate modular components that can be independently manufactured and then quickly assembled. This segmentation enables standardized connection interfaces and reduces the complexity of the overall assembly process compared to conventional monolithic or tightly-integrated designs.
Solution Approach 2:
The reinforcement core is pre-formed and positioned within the polymeric material before final assembly operations. This preliminary action simplifies the assembly process by eliminating the need for complex post-assembly reinforcement operations and reduces the labor required during final assembly.
3Strength
If the stirrup structure is reinforced to maintain strength, then structural integrity is improved, but the weight increases
Solution Approach 1:
The stirrup uses a composite construction with a polymeric frame and embedded metallic reinforcement core. The polymeric material provides the base structure with low weight, while the metallic core strategically placed within provides the necessary mechanical resistance and strength, achieving strength enhancement without proportionally increasing weight.
Solution Approach 2:
The reinforcement core is strategically positioned within the polymeric frame at specific locations where mechanical strength is most needed (such as along the side arms and support arms). This localized reinforcement provides high mechanical resistance only where required, rather than uniformly throughout the entire stirrup, thereby minimizing unnecessary weight increase.
