Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the tire structure drum and feeder are installed in fixed positions with the axis of rotation based on a feeder axle, then the system structure is simple and stable, but the alignment accuracy between the tire component and the drum axis deteriorates when the component is bent or misaligned
Solution Approach 1:
The patent applies the dynamics principle by making the axis of rotation of the tire structure drum adjustable rather than fixed. The actuator enables the drum axis to dynamically adapt its position and orientation based on the actual alignment of the tire component on the feeder pan, resolving the contradiction between manufacturing precision and device complexity by introducing controlled movability where needed.
Solution Approach 2:
The patent implements parameter changes by allowing the axis of rotation parameters (position and orientation) to be modified based on sensor feedback. The control unit adjusts the drum axis parameters to match the tire component alignment, transforming a static system into one that can adapt its parameters to achieve high alignment accuracy without requiring complex mechanical structures.
2Productivity
If the tire component is fed based on storage memory causing elastic deformation, then the feeding process is continuous, but the component geometry becomes non-linear and misaligned
Solution Approach 1:
The patent applies feedback by using a sensor device to detect the actual geometry and alignment of the tire component on the feeder pan, then feeding this information to the control unit which adjusts the drum axis accordingly. This closed-loop feedback system maintains feeding continuity while compensating for alignment errors caused by elastic deformation during storage and feeding.
Solution Approach 2:
The system performs preliminary detection of component alignment before the winding process begins. The sensor device measures the component geometry and alignment in advance, allowing the control unit to pre-adjust the drum axis position and orientation to compensate for expected misalignment, ensuring accurate winding from the start.
