Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple conductor passage openings are arranged closely next to each other on a flat busbar area, then the terminal component achieves compact design and efficient space utilization, but the manufacturing complexity increases due to deep-drawing process requirements
Solution Approach 1:
The patent transitions from traditional side-by-side conductor passage openings to a front-to-back arrangement on a flat busbar area, utilizing the depth dimension to achieve compactness while maintaining manufacturability through deep-drawing processes
2Stability of the object's composition
If a common clamping spring with opposing clamping sections is used to clamp conductors in adjacent passage openings, then the clamping force is distributed effectively and stability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple clamping functions into a single common clamping spring with opposing clamping sections, where one spring element serves multiple conductor passage openings simultaneously, achieving stable clamping while reducing the total number of spring components
Solution Approach 2:
The common clamping spring is designed to perform multiple clamping operations across different conductor passage openings, making a single component universally applicable to multiple clamping points along the busbar
3Length of stationary object
If conductor passage openings are arranged one behind the other in the longitudinal direction, then the terminal component achieves a reduced overall height, but the conductor insertion accessibility may be reduced
Solution Approach 1:
The patent arranges conductor passage openings in the longitudinal depth direction rather than side-by-side, utilizing the depth dimension to reduce overall height while maintaining accessibility through strategic positioning of openings
