Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual insertion method is used, then operation simplicity is maintained, but insertion depth precision deteriorates
Solution Approach 1:
The patent replaces the purely mechanical manual insertion method with an electrical detection system. A detection component with detection circuit electrically contacts the connector terminal to sense insertion depth, substituting human tactile control with electrical measurement to achieve precise depth control while maintaining operational simplicity.
Solution Approach 2:
The detection component serves as an intermediary between the operator and the connector terminal. It electrically contacts the terminal during insertion and transmits depth information to the detection circuit, enabling precise measurement without requiring the operator to directly control the insertion depth.
2Manufacturing precision
If detection component is added, then insertion depth precision is improved, but device complexity increases
Solution Approach 1:
The detection component is designed to perform multiple functions: it serves as both a detection element for measuring insertion depth and as part of the electrical connection path. This multi-functionality reduces the need for separate dedicated detection devices, thereby limiting the increase in overall device complexity.
Solution Approach 2:
The detection component is nested within the connector assembly structure. It is inserted into the connector housing along with the terminal, utilizing the existing spatial arrangement and pathways, which minimizes additional structural complexity while enabling precise depth detection.

AI summary
A detection device for detecting an insertion depth of a connector terminal in a connector housing includes a detection component and a detection circuit. The detection component is inserted into a front port of the connector housing and electrically contacts a front end of the connector terminal inserted in the connector housing from a rear port of the connector housing. The detection circuit has one end electrically connected to the detection component and the other end electrically connected to a rear end of the connector terminal or to a connector cable connected to the rear end of the connector terminal. The detection circuit is in a connected state when the connector terminal reaches a predetermined insertion depth and electrically contacts the detection component. The detection circuit is in a disconnected state when the connector terminal does not reach the predetermined insertion depth and does not electrically contact the detection component.
