Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screwing is used for grounding of terminals, then reliable electrical connection is achieved, but larger installation space is required and tool-assisted operation is needed
Solution Approach 1:
The patent replaces the screwing mechanical system with a spring-based clamping mechanism. The spring-loaded夹持结构 provides reliable electrical contact through elastic force, eliminating the need for screws and tool-assisted operations while reducing installation space requirements
Solution Approach 2:
The spring mechanism automatically maintains contact pressure on the conductive wire without requiring external tools or manual adjustment. The elastic deformation of the spring provides self-regulating clamping force, enabling tool-free installation and operation
2Adaptability or versatility
If one grounding part is used, then grounding of one terminal is implemented, but simultaneous grounding of multiple terminals cannot be achieved
Solution Approach 1:
The grounding terminal is designed with multiple independent clamping units that can simultaneously ground multiple conductive wires. Each unit maintains the same spring-based mechanism, allowing the single device to perform multiple grounding functions without proportionally increasing overall complexity
Solution Approach 2:
The terminal structure is divided into multiple independent clamping units, each capable of grounding one conductive wire. This segmentation allows flexible configuration for different numbers of terminals while maintaining a standardized modular design that doesn't linearly increase complexity
3Reliability
If continuous grounding wire is used for joint grounding, then all electrical devices can be grounded, but the wire cannot be easily inserted or removed without tools
Solution Approach 1:
The spring-based clamping mechanism provides dynamic adjustment capability, allowing the terminal to automatically adapt to different wire sizes and insertion forces. This enables tool-free insertion and removal of conductive wires while maintaining reliable electrical contact throughout operation
