Camera Module Positioning Sleeve for Motor Vehicle Lens Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera modules for motor vehicles have a large gap between the camera mounting hole and the camera lens, which can lead to detachment under lateral forces, compromising camera functionality.
Innovation Solution
A camera module with a positioning sleeve that partially encases the camera lens, allowing for adjustable gap size to absorb forces and minimize contamination, produced via injection molding for adaptable geometry matching the vehicle component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large gap is provided between the camera mounting hole and the camera lens, then the camera lens is protected from contact with the component on the motor vehicle, but the camera lens can detach from the circuit board under lateral or transverse forces
Solution Approach 1:
The positioning sleeve acts as an intermediary element between the camera lens and the component on the motor vehicle. It provides mechanical support and positioning for the camera lens while absorbing lateral and transverse forces, preventing both detachment and direct contact damage. The positioning sleeve translates the large gap design into effective force absorption without compromising lens stability.
2Manufacturing precision
If a small gap is provided between the camera mounting hole and the camera lens, then the camera lens is securely positioned, but the camera lens is vulnerable to damage from lateral or transverse forces
Solution Approach 1:
The positioning sleeve provides beforehand cushioning by being pre-configured with appropriate clearance and mechanical properties to absorb lateral and transverse forces before they can reach the camera lens. This cushioning effect protects the precisely positioned camera lens from damage while maintaining its secure positioning.
3Adaptability or versatility
If the camera mount is produced using injection molding, then the shape can be easily adapted to the geometry of the component on the motor vehicle, but additional adaptation during production is required
Solution Approach 1:
The injection molding process performs preliminary action by pre-adapting the camera mount geometry to match the component on the motor vehicle during the molding process itself. Features such as the positioning sleeve geometry and mounting interfaces are built-in during production, eliminating the need for additional adaptation steps afterward.
