Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional pluggable terminal blocks are used with exposed power wire portions, then ease of connection is improved, but short circuit risk increases due to incomplete insertion or wire stress
Solution Approach 1:
The patent introduces an intermediary connector system that mediates between the power wires and the terminal block. The connector includes a housing with a receiving space that guides wire insertion, and internal contact structures that ensure proper engagement before electrical connection is established. This intermediary structure prevents direct exposure of wires while maintaining ease of connection.
Solution Approach 2:
The connector is designed to perform preliminary actions before final electrical connection: the receiving space guides and positions the wire, the clamp mechanism pre-secures the wire in place, and the contact structures are positioned to engage only after proper insertion. This preliminary mechanical guidance and securing prevents incomplete insertion and ensures reliable connection before electrical contact is made.
2Ease of manufacture
If power wires are allowed to move freely in conventional terminal blocks, then ease of installation is improved, but connection stability deteriorates due to stress and disconnection
Solution Approach 1:
The connector is segmented into distinct functional zones: a receiving space for wire insertion, a clamping mechanism for securing, and contact structures for electrical connection. The clamp is a separate movable component that independently secures the wire, allowing easy installation while providing stable mechanical fixation that prevents stress and disconnection.
Solution Approach 2:
The clamp mechanism is designed to be dynamic during installation (easy to open and close for wire insertion) but becomes static and rigid once closed, providing strong mechanical securing. This dynamic-to-static transition allows ease of installation while ensuring connection stability under stress.
3Adaptability or versatility
If exposed power wire portions are used in conventional terminal blocks, then adaptability of connection methods is improved, but harmful effects increase due to smoke and arcing from short circuits
Solution Approach 1:
The connector housing acts as an intermediary enclosure that contains the connection process. The receiving space guides wire insertion, the clamp secures the wire, and the contact structures make connection within the protected housing. This intermediary structure eliminates exposed wire portions while maintaining adaptability of connection methods, and prevents smoke and arcing by containing any potential electrical faults within the housing.
Solution Approach 2:
The harmful exposed wire portions are extracted and removed from the connection system. The connector encloses all electrical contacts and wire connection points within the housing, eliminating exposed conductors that could cause short circuits, smoke, and arcing, while still providing adaptable connection methods for different wire types and sizes.
