Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple actuators and complex guides are used to transport woven harness elements, then the transport reliability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated carrier device that performs both transport and positioning operations. The carrier device integrates the holding element, repulsion element, and actuator mechanisms into one unified system, eliminating the need for separate actuators and complex guides while maintaining transport reliability.
Solution Approach 2:
The carrier device is designed as a multi-functional component that handles multiple operations: transporting the weaving harness element, positioning it at the correct location, and facilitating its release. This universal design replaces multiple specialized components with one versatile device, reducing overall system complexity.
2Manufacturing precision
If complex guides are used to guide the holding element, then the positioning precision is improved, but the wear increases
Solution Approach 1:
The patent extracts the guiding function from separate complex guide structures and integrates it directly into the carrier device itself. The carrier device's built-in geometry and configuration provide the necessary positioning guidance, eliminating external guides that would otherwise wear from continuous contact with the holding element.
Solution Approach 2:
The carrier device is designed to be self-guiding through its own structural configuration. The holding element and repulsion element are positioned and oriented by the carrier device's inherent geometry, eliminating the need for external guiding structures that would generate wear over time.
3Device complexity
If fewer actuators are used, then the device complexity is reduced, but the reliability may deteriorate
Solution Approach 1:
The patent merges the functions of multiple actuators into a single integrated actuator system within the carrier device. This unified actuator performs all necessary operations—transport, positioning, and release—thereby reducing the number of actuators while maintaining reliability through the coordinated action of the integrated system.
