Plug Connector Marking Position for Waterproof Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial vehicle plug connections require robustness and water protection while maintaining visibility for identification markings, which is challenging due to the obscuration of markings by waterproof coatings.
Innovation Solution
The solution involves placing markings on the male connector part in an area that can be lowered into the female connector part, ensuring the markings are protected and visible only when the connection is disassembled, allowing for functional preservation without the need for protective lacquer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a waterproof and/or water-repellent protective coating is applied to the plug connection, then water protection is improved, but the identification marking becomes unrecognizable
Solution Approach 1:
The marking is arranged on the male plug connection part in an area that can be lowered into the female plug connection part before the protective coating is applied. This preliminary positioning allows the marking to be protected by the engagement geometry itself, eliminating the need for additional protective measures that would obscure the marking.
Solution Approach 2:
The marking on the male plug connection part is nested within the female plug connection part when connected. The marking area on the male part is designed to be receivable in a corresponding area of the female part, creating a nested configuration that protects the marking while maintaining visibility when needed.
2Loss of information
If the marking is made visible on the plug connection, then identification is improved, but water protection is compromised
Solution Approach 1:
The marking is nested within the female plug connection part when the connectors are engaged. This nested configuration provides water protection while the marking remains accessible for identification when the connectors are separated or during the connection process.
Solution Approach 2:
The marking is placed in a specific local area on the male plug connection part that has different functional requirements. This area is designed to be visible and accessible for identification while the rest of the connection maintains robust water protection through the protective coating.
3Reliability
If a protective lacquer is applied to protect the marking, then marking preservation is improved, but water protection capability is reduced
Solution Approach 1:
The marking is positioned on the male plug connection part in advance, in an area that will be lowered into the female part. This preliminary positioning allows the marking to be protected by the engagement geometry itself, eliminating the need for additional protective lacquer that would compromise water protection.
Solution Approach 2:
The plug connection structure itself provides protection for the marking through its geometric design. The male part's marking area is designed to be receivable in the female part, creating a self-protecting configuration that eliminates the need for additional protective measures.
