Solution Overview
Problem
Existing electrical connectors require users to disassemble connections or insert testing leads inside the connectors to test wire leads, leading to inefficiency, inaccuracies, and increased effort, especially when dealing with multiple wires.
Innovation Solution
A funnel-shaped wire nut with a small top opening for a testing probe and an internal metal spiral thread connected to a metal ball, allowing for non-invasive testing of wire leads without disassembly, using a testing probe to measure electrical parameters through the metal ball and spiral thread.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users insert testing leads inside the connector to test wire leads, then electrical parameters can be measured, but the process becomes complex and time-consuming
Solution Approach 1:
The patent introduces a testing port as an intermediary interface that allows external testing leads to contact the metal spiral thread without requiring insertion into the connector interior. This mediator structure simplifies the testing process while maintaining measurement accuracy by providing a dedicated access point for electrical parameter measurement.
Solution Approach 2:
The patent extracts the testing function from the interior of the connector by providing a separate testing port on the outer surface. This allows the testing operation to be performed externally without disassembling or inserting leads into the connector, thereby reducing testing complexity while maintaining measurement capability.
2Measurement precision
If users remove the electrical connector to test the wires, then wire testing can be performed, but productivity is reduced and connection integrity may change
Solution Approach 1:
The testing port serves as a mediator that enables wire testing while the connector remains installed on the electrical component. This allows accurate wire testing to be performed without removing the connector, thereby maintaining connection integrity and significantly improving testing productivity.
Solution Approach 2:
The connector design incorporates the testing port as a self-service feature that enables users to test wires directly through the connector without requiring connector removal. This self-contained testing capability maintains connection integrity while improving productivity by eliminating the time-consuming disassembly and reassembly process.
3Measurement precision
If users push testing leads inside the connector, then electrical parameters can be measured, but the process requires significant effort and time
Solution Approach 1:
The testing port acts as an intermediary access point that allows testing leads to reach the metal spiral thread without requiring insertion into the connector interior. This significantly reduces the effort and time required for testing while maintaining measurement precision by providing direct electrical contact through the port.
Solution Approach 2:
The patent extracts the testing access from the interior of the connector by providing a testing port on the outer surface. This allows users to perform electrical parameter measurements externally without the cumbersome process of inserting leads inside the connector, thereby greatly improving ease of operation while maintaining measurement accuracy.
