Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wire length differences within dimensional tolerance are allowed, then ease of manufacture is improved, but manufacturing precision deteriorates due to uneven twist pitch
Solution Approach 1:
The patent applies preliminary action by pre-absorbing wire length differences using the absorbing member before the twisting process begins. The absorbing member is positioned between the clamps and the twisting section to take up excess length in advance, ensuring that the twisting operation proceeds with uniform wire tension and produces consistent twist pitch throughout the twisted section.
2Adaptability or versatility
If wire length differences are absorbed by the twisted section, then adaptability to wire length variation is improved, but reliability deteriorates due to quality inconsistency
Solution Approach 1:
The patent extracts the wire length difference absorption function from the twisted section itself and relocates it to a dedicated absorbing member. This separating function allows the twisted section to focus solely on providing consistent electrical connection with uniform twist pitch, while the absorbing member handles the variability, thereby improving both adaptability and reliability simultaneously.
3Manufacturing precision
If measurement and quality guarantee processes are implemented, then manufacturing precision is improved, but productivity deteriorates due to additional processing time
Solution Approach 1:
The patent implements self-service by designing the absorbing member to automatically compensate for wire length differences during the twisting process itself. The absorbing member passively takes up excess length through its elastic deformation or mechanical compliance, eliminating the need for separate measurement and quality guarantee processes, thereby maintaining high precision while preserving productivity.
