Solution Overview

Problem

In existing connectors, the pin of the male connector often experiences breakdown or damage during connection due to improper alignment and contact with parts other than the pin hole, leading to connection defects.

Innovation Solution

The connector design includes a movable electrical connection part that is fixed in position relative to the physical connection part, allowing for precise alignment before electrical connection, and a mechanism to adjust the position of the pin to prevent damage during connection and disconnection, using a combination of screwing, levers, and locking mechanisms to maintain the correct state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the pin is directly connected to the female connector during assembly, then the connection process is simple and fast, but the pin may contact parts other than the pin hole causing breakdown or damage

Engineering Contradiction:
Improveconnection speedVSAvoidpin integrity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The connector is divided into two independent parts: a physical connection part (coupling nut and screw thread) and an electrical connection part (pin and pin hole). These parts can be connected separately, allowing the physical connection to be established first to align the components, followed by the electrical connection. This segmentation prevents the pin from contacting incorrect parts during assembly while maintaining connection efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The physical connection part is assembled and aligned before the electrical connection part is connected. By preliminarily establishing the physical connection between the coupling nut and screw thread, the pin and pin hole are pre-aligned to ensure proper positioning, preventing the pin from contacting incorrect parts during the subsequent electrical connection.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If the pin position is fixed relative to the coupling nut, then the structure is simple, but the pin may be misaligned with the pin hole causing damage during connection

Engineering Contradiction:
Improvestructure simplicityVSAvoidalignment precision
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The electrical connection part is designed to be movable relative to the physical connection part. The pin can move independently within a certain range to accommodate alignment variations and ensure proper insertion into the pin hole. This dynamic design maintains structural simplicity while significantly improving alignment precision and preventing pin damage.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the pin is held stationary during connection, then the structure is straightforward, but the pin cannot adapt to position variations causing contact with wrong parts

Engineering Contradiction:
Improveconnection easeVSAvoidconnection accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The electrical connection part is designed with movable capability, allowing the pin to adjust its position dynamically during the connection process. This movement capability enables the pin to adapt to position variations and maintain accurate alignment with the pin hole, preventing contact with incorrect parts while keeping the operation straightforward.

Inventive Principle:
Principle #15Dynamics
