Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If special sockets and crimping tools are used to establish electrical connections, then reliable electrical connection is achieved, but the handling process becomes cumbersome and time-consuming
Solution Approach 1:
The patent extracts the crimping operation from the connection process by using pre-crimped sockets that are already prepared with conductors. This allows the socket to be simply inserted into the relay base without requiring a crimping tool at the installation site, thereby maintaining reliable electrical connection while significantly improving ease of operation.
Solution Approach 2:
The conductors are pre-crimped to the sockets before installation, performing the complex crimping action in advance. This preliminary action eliminates the need for special crimping tools during installation, allowing workers to simply insert the pre-prepared sockets into the relay base, thus improving handling ease while ensuring reliable electrical connections.
2Reliability
If sockets are crimped and pushed into recesses for electrical connection, then electrical connectivity is established, but removing conductors requires special extractor tools
Solution Approach 1:
The patent extracts the extractor tool requirement by designing a release mechanism that allows sockets to be removed using simple manual force or basic tools. The socket can be released from the recess through a straightforward extraction action, eliminating the need for specialized extractor tools while maintaining secure connection during operation.
Solution Approach 2:
The connection system employs a dynamic retention mechanism where the socket can be firmly held in the recess during operation but can be easily released when needed. This dynamic characteristic allows the same structure to provide both secure electrical connection and easy removal, improving ease of repair without compromising connection stability.
3Area of stationary object
If a compact relay base design is implemented, then space efficiency is improved, but the connection units must be densely arranged
Solution Approach 1:
The patent combines multiple functions into the connection unit structure, integrating the socket, conductor, and retention mechanism into a single modular component. This merging allows the connection units to be densely arranged in the relay base without increasing overall complexity, as each unit is a self-contained module that can be systematically organized to achieve compact space utilization.

AI summary
The invention relates to a relay base for connection to a plug-in relay (4). The relay base comprises a plurality of connection units. Each connection unit comprises an electrically conductive socket member (6) having a first end and a second end, the first end being configured to receive a pin (8) of the relay (4), an electrically conductive flexible connector (10) having a first end and a second end, the first end of the flexible connector being electrically connected to the second end of the socket member, and an electrically conductive insert (20) having a first end and a second end, the first end of the insert being electrically connected to the second end of the flexible connector (10). The second end of the insert (20) is configured as an electrical connectivity receptacle, for example a screw type terminal, comprising a thread for receiving a screw. The configuration of the second end of the insert (20) allows for facilitated making and breaking an electrical connection between the relay (4) and an external wiring.
