Vehicle Lamp Sensor Cover With Quarter-Turn Sealing Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lamp assemblies with sensors face challenges in easy installation and removal of sensor covers, and maintaining a robust seal without the use of tools.
Innovation Solution
A sensor cover for a vehicle lamp assembly that is rotatable between two orientations, allowing for tool-free attachment and detachment, and establishing an interference fit for secure positioning, while also incorporating a seal for environmental protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensor cover is designed to be securely attached to the housing, then the reliability of sensor positioning is improved, but the ease of installation and removal deteriorates
Solution Approach 1:
The cover is designed with rotational movement capability, transitioning from a static attachment to a dynamic quarter-turn mechanism. The cover rotates 90 degrees from an inserted position to a locked position, where interference fit features engage to secure the cover while maintaining tool-free operation for both installation and removal
Solution Approach 2:
The cover and housing feature asymmetric interference fit geometries including protrusions and recesses that engage only in specific rotational orientations. This asymmetric design prevents accidental detachment while requiring only a simple quarter-turn motion for intentional installation or removal by the user
2Object-affected harmful factors
If a seal is incorporated to establish environmental protection, then the resistance to environmental factors is improved, but the device complexity increases
Solution Approach 1:
The seal is integrated directly into the cover body as an inherent feature rather than a separate component. The sealing element is molded as part of the cover structure, combining the sealing function with the cover's structural role to protect the sensor while avoiding additional parts or assembly steps
Solution Approach 2:
The seal utilizes a flexible sealing element that can deform to accommodate the interference fit engagement between the cover and housing. This flexible seal establishes an environmental barrier while being accommodated within the cover's structure without requiring additional complex sealing mechanisms
