Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated assembly and stitching systems are implemented, then productivity and consistency are improved, but device complexity increases
Solution Approach 1:
The automated manufacturing system is divided into distinct functional modules: a conveyance mechanism for transporting part stacks, a stitching mechanism with needle and presser foot, and a shared control mechanism. Each module operates semi-independently while being coordinated through the shared control system, allowing for easier maintenance and reduced overall system complexity.
Solution Approach 2:
The shared control mechanism serves multiple functions simultaneously: it controls the conveyance mechanism's movement, synchronizes the needle's stitching motion, and coordinates the presser foot's positioning. This multi-functionality reduces the need for separate control systems for each component, thereby reducing device complexity while maintaining high productivity.
2Manufacturing precision
If synchronized control of conveyance mechanism and stitching needle is implemented, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The control functions for the conveyance mechanism and the stitching mechanism are merged into a single shared control mechanism. This unified controller synchronizes the movement of the conveyance mechanism with the needle's stitching motion, ensuring precise stitching alignment without requiring separate complex control systems for each component.
Solution Approach 2:
The shared control mechanism monitors and coordinates the positions and movements of both the conveyance mechanism and stitching needle in real-time, enabling precise synchronization. This feedback-based coordination ensures that stitching operations occur at the correct positions on the shoe parts while maintaining manufacturing precision.
