Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two pressing buttons are used to disassemble the seat hinge, then the disassembly function is achieved, but the structure becomes complex and the disassembly steps become complicated
Solution Approach 1:
The patent combines two separate pressing buttons into a single integrated button structure. The single button simultaneously actuates both locking mechanisms, merging two independent operations into one unified action, thereby simplifying the overall structure while maintaining the disassembly function.
Solution Approach 2:
The single button is designed to perform multiple functions: it simultaneously releases both locking pins and initiates the disassembly process. This multi-functional design eliminates the need for separate buttons, reducing structural complexity while preserving complete disassembly capability.
2Ease of operation
If the damper and lock piece are stored in sliding grooves, then the disassembly function is achieved, but the machining accuracy and manufacturing cost increase
Solution Approach 1:
Instead of storing the lock piece in a sliding groove as in conventional designs, the patent inverts the approach by having the lock piece engage directly with the hinge body through a simple insertion hole. This eliminates the complex sliding groove structure, reducing machining accuracy requirements and manufacturing cost while maintaining the disassembly function.
3Reliability
If the lock piece is stored in the fixed shaft with sliding grooves, then the locking function is achieved, but the manufacturing cost and machining difficulty increase
Solution Approach 1:
The patent extracts the lock piece from the fixed shaft structure, eliminating the need for sliding grooves in the fixed shaft. The lock piece operates independently through a simple insertion hole, separating the locking function from complex structural requirements, thereby reducing manufacturing cost and machining difficulty while preserving reliable locking functionality.
4Reliability
If baffle arms are stored in sliding grooves, then the locking mechanism functions, but the strength of the lock piece and fixed shaft decreases
Solution Approach 1:
The patent removes the baffle arms and sliding grooves from the design. The locking mechanism achieves its function through direct engagement of the lock piece with the hinge body via a simple insertion hole, eliminating the structural weakening caused by sliding grooves and maintaining the strength of the lock piece and fixed shaft.
5Ease of operation
If a rotational mechanism is used for disassembly, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent designs the single button to automatically initiate the rotational disassembly mechanism when pressed. The user's simple pressing action triggers the self-contained rotational mechanism that automatically performs the disassembly, eliminating the need for complex manual manipulation while keeping the overall device structure simple.
