Multipolar Connector Locking Module for Alignment-Free Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-pole connectors require precise angular alignment of components, which is inconvenient for users, especially in low-light or hidden conditions, and lack effective sealing in harsh environments.
Innovation Solution
A locking module with a flexible membrane and ogives, sealed by a locking spring, allows connection without prior orientation and provides sealing against environmental factors like freezing and dust.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If precise angular alignment is required for connector components, then connection reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The connector components utilize asymmetrical constructions with specific shapes that allow only connection in a predetermined relative position. The male and female connectors have complementary asymmetric geometries that guide proper alignment during insertion, ensuring reliable connection while maintaining ease of operation through self-alignment features.
Solution Approach 2:
The connector design incorporates preliminary alignment features such as positioning ribs, guide surfaces, and predetermined angular orientations that automatically align the components before final connection. This preliminary action ensures proper orientation without requiring manual alignment efforts from the user.
2Volume of moving object
If connector components are made non-visible or hard to locate, then device compactness is improved, but ease of operation deteriorates
Solution Approach 1:
The connector components incorporate visual indicators such as color-coded markings, illuminated elements, or contrasting colors that make the connectors easily locatable and identifiable. These visual cues allow users to quickly find and identify connector positions without compromising device compactness, as the indicators are integrated into the existing connector structure.
3Reliability
If sealing structure is added to protect against environmental factors, then reliability in harsh environments is improved, but device complexity increases
Solution Approach 1:
The connector incorporates flexible sealing membranes and thin film barriers that provide effective sealing against environmental factors such as moisture, dust, and contaminants. These flexible seals are integrated into the connector housing and contact interfaces, providing protection without requiring complex multi-component sealing systems.
Solution Approach 2:
The sealing function is merged with the structural components of the connector. The housing itself incorporates sealing features, and the sealing elements are integrated into the contact interfaces and locking mechanisms. This merging of functions reduces overall device complexity while maintaining effective environmental protection.
