Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electromagnets are used to transfer cord ply segments between conveyors, then the transfer function is achieved, but the magnetic attraction between electromagnets causes complexity and high cost
Solution Approach 1:
The patent extracts the magnetic field generation function from the transfer member structure itself and places it in separate, removable magnetic field sources. These sources can be independently positioned and controlled, allowing the magnetic field to be applied only when needed for transfer, eliminating continuous magnetic attraction and the associated complexity and cost of switching mechanisms
Solution Approach 2:
The patent introduces magnetic field sources as intermediary elements between the transfer members. These sources create the necessary magnetic attraction for transfer without requiring the transfer members themselves to be electromagnets, simplifying the overall system architecture and reducing costs
2Ease of operation
If electromagnets are used to transfer cord ply segments, then transfer is achieved, but separation of conveyors is counteracted by magnetic force requiring additional control mechanisms
Solution Approach 1:
The patent makes the magnetic field sources dynamically positionable relative to the transfer members. The magnetic field sources can be moved into position during transfer and removed or repositioned during separation, allowing the system to adapt its magnetic field configuration to the operational phase without requiring complex switching controls
Solution Approach 2:
The patent positions the magnetic field sources in advance at locations where they will be most effective for transfer, and maintains this positioning throughout the transfer process. This preliminary and sustained positioning eliminates the need for complex real-time control during separation, as the magnetic field sources are simply removed or repositioned after transfer completion
