Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated assembly and stitching systems are implemented, then productivity and consistency are improved, but device complexity increases

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Manufacturing precision

If synchronized control of conveyance mechanism and stitching needle is implemented, then manufacturing precision is improved, but device complexity increases

Engineering Contradiction:
Improvestitching alignment precisionVSAvoidcontrol mechanism complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #23Feedback
