Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional wiring fields or terminals are used to provide multiple connection points, then the functionality and versatility of the surge protection device is improved, but the device complexity and cost increase
Solution Approach 1:
The patent combines multiple separate wiring fields and terminals into a single integrated terminal base that provides multiple connection points for pole and earthing connections. This merging approach eliminates the need for additional separate wiring fields while maintaining the capability to connect multiple conductors, thereby reducing device complexity and cost without sacrificing connection versatility.
Solution Approach 2:
The terminal base is designed as a multi-functional component that serves both as the mounting structure for the protective switch and as the wiring terminal providing multiple connection points. This universal design allows the same component to fulfill multiple functions (structural support + electrical connection), eliminating the need for separate dedicated terminals and reducing overall device complexity.
2Reliability
If multiple separate terminals are used for pole and earthing connections, then the reliability of conductor connections is improved, but the manufacturing cost and assembly complexity increase
Solution Approach 1:
The patent integrates multiple connection points for pole and earthing connections into a single terminal base component, reducing the total number of separate parts that need to be manufactured and assembled. This merging maintains reliable electrical connections while simplifying the manufacturing process and reducing production costs.
Solution Approach 2:
The terminal base is designed with distinct, separately accessible connection points for different conductors (pole connections and earthing connection), allowing each connection point to be reliably terminated independently while being part of a single integrated component. This segmentation within integration maintains connection reliability while simplifying manufacturing.
3Ease of operation
If a single integrated terminal base is used instead of multiple separate terminals, then the ease of installation and cost-effectiveness is improved, but the flexibility for complex wiring configurations may be reduced
Solution Approach 1:
The terminal base is designed as a universal mounting and connection structure that accommodates both simple and complex wiring configurations. It provides multiple connection points for pole connections and earthing connections, allowing the same integrated component to serve various installation scenarios from basic to complex wiring needs.
Solution Approach 2:
The terminal base incorporates distinct, separately accessible connection points for different conductors, allowing installers to connect conductors independently at each point. This segmented design within the integrated base maintains wiring configuration flexibility while simplifying installation compared to multiple separate terminals.
