Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a one-way circulation mode with underground portion is used, then the towing device can push the towed vehicle, but the construction cost and device complexity increase significantly
Solution Approach 1:
Instead of using a conventional one-way circulation mode where the push member returns through an underground portion, this invention inverts the approach by using a rotating yoke system where the towing mechanism rotates 180 degrees to return the yokes to their initial position. This eliminates the need for complex underground constructions while maintaining the towing function.
Solution Approach 2:
The invention introduces a dynamic rotating yoke system where the front and rear yokes can rotate horizontally around vertical shafts. This dynamic mechanism allows the yokes to change orientation from perpendicular to parallel to the towing path, enabling both towing and return movements without fixed underground structures.
2Ease of operation
If a one-way circulation mode with underground portion is used, then the towing device can push the towed vehicle, but the flexibility and assembly efficiency decrease
Solution Approach 1:
The towing device is segmented into independent modular components including the towing mechanism, front yoke assembly, rear yoke assembly, and control system. Each module can be assembled and disassembled independently, greatly improving assembly efficiency and flexibility for different deployment scenarios.
Solution Approach 2:
The rotating yoke mechanism provides operational flexibility by allowing the yokes to rotate between perpendicular and parallel positions relative to the towing path. This dynamic adjustment enables the device to adapt to different towing scenarios and facilitates easier assembly and disassembly operations.
3Adaptability or versatility
If the yokes rotate horizontally around vertical shafts, then the towing operation becomes more flexible, but the mechanical complexity increases
Solution Approach 1:
The rotating yoke system serves multiple functions: it enables the yokes to approach vehicle wheels perpendicularly for effective towing, rotates to parallel position for return movement, and can be controlled to adjust to different vehicle positions. This multi-functionality reduces the need for separate mechanisms for different operations.
Solution Approach 2:
The control system acts as an intermediary between the operator and the mechanical components, coordinating the rotation of front and rear yokes, the movement of the towing mechanism, and the engagement/disengagement of clamping devices. This centralized control simplifies the overall system complexity by providing automated coordination.
