Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional conductor terminal structure is used, then the terminal can connect electrical conductors, but it requires additional components like busbars to connect a large number of conductors
Solution Approach 1:
The patent merges the functions of multiple conductors into a single terminal housing. Multiple first conductors (10-20) are simultaneously connected to a second conductor (3) within one housing (2), eliminating the need for separate terminals or busbars. This consolidation increases the number of connectable conductors while reducing overall structural complexity.
Solution Approach 2:
The housing (2) serves multiple functions: it provides structural support, guides multiple first conductors through insertion guide openings (22), receives the second conductor through conductor insertion opening (23), and houses the clamping spring device (4). This multi-functionality allows a single component to handle numerous conductors without requiring additional specialized parts.
2Ease of manufacture
If a simple terminal structure is used, then manufacturing and assembly are economical, but the ability to connect multiple conductors efficiently is limited
Solution Approach 1:
The terminal is segmented into distinct functional zones within the housing: insertion guide openings (22) for first conductors, conductor insertion opening (23) for the second conductor, and clamping regions for the spring device (4). This segmentation allows each component to be manufactured independently using standard processes, maintaining ease of manufacture while enabling efficient multi-conductor connection through coordinated assembly.
3Device complexity
If conductors are connected directly without busbars, then the structure is simpler and more economical, but good electrical contact must be ensured
Solution Approach 1:
The clamping spring device (4) acts as an intermediary between the first conductors (10-20) and the second conductor (3). It provides reliable electrical contact through elastic clamping force, ensuring good conductivity while maintaining mechanical stability. The spring device mediates the connection without requiring rigid busbars, thus simplifying the structure while ensuring reliability.
Solution Approach 2:
The clamping spring device utilizes elastic deformation as a key parameter to maintain reliable electrical contact. The spring force dynamically adjusts to accommodate conductor variations and ensures consistent contact pressure, thereby guaranteeing good electrical conductivity. This parameter-based approach replaces rigid mechanical connections with flexible elastic ones, simplifying the overall structure.
