Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fasteners with nuts or washers are used to secure the connection plate to the boot, then the assembly can be secured, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent merges multiple fasteners into a single integrated T-shaped fastener that simultaneously secures the connection plate to the boot. This single fastener replaces what would traditionally require multiple nuts and washers, simplifying the assembly process while maintaining secure attachment. The T-shaped design allows the fastener to engage with corresponding slots in both the connection plate and boot, creating a unified fastening mechanism.
Solution Approach 2:
The T-shaped fastener serves multiple functions: it secures the connection plate to the boot, provides structural support, and enables quick assembly and disassembly. This multi-functional design eliminates the need for separate components like nuts and washers, reducing complexity while maintaining the securing function.
2Strength
If multiple separate nuts or washers are used for fastening, then the connection can be established, but the overall structural strength and deformation resistance become insufficient
Solution Approach 1:
By combining multiple fastening functions into a single T-shaped fastener, the patent creates a more structurally sound connection. The integrated design distributes forces more effectively across the connection point compared to separate nuts and washers, enhancing overall structural strength and deformation resistance while reducing the number of components.
3Force
If conventional fastening methods are used, then the connection plate can be secured, but the force transmission becomes poor and inefficient
Solution Approach 1:
The T-shaped fastener creates a more efficient force transmission path by integrating the fastening mechanism into a single structural element. This design allows forces to be transmitted more directly from the roller assembly through the connection plate to the boot, improving force transmission efficiency compared to conventional multi-component fastening systems.
