Solution Overview
Problem
Existing camera devices for vehicles face challenges in reducing the size of on-board systems while maintaining the optical axis parallel to the vehicle's longitudinal axis, which requires complex and costly assembly of inclined printed circuit boards connected by flexible electrical sheets.
Innovation Solution
A camera device design featuring a rectangular motherboard with a tiltable secondary section, allowing adjustment of the camera module's optical axis angle through a pivot axis, facilitated by a recess and slots, enabling easier assembly and alignment with the main section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the printed circuit board carrying out image processing is arranged in an inclined manner to adjust the optical axis angle, then the optical axis alignment with vehicle longitudinal axis is improved, but the assembly complexity and cost increase due to flexible electrical sheet connections
Solution Approach 1:
The motherboard is divided into a main section and a secondary section that can be tilted independently relative to each other around a pivot axis. This segmentation allows the optical axis alignment to be adjusted without requiring flexible electrical sheets, as the electrical connections are maintained through the rigid pivot connection.
Solution Approach 2:
The inclination angle of the secondary section relative to the main section is varied to adjust the optical axis alignment. By changing this geometric parameter, the system achieves proper alignment with the vehicle longitudinal axis while maintaining a simple rigid assembly structure.
2Manufacturing precision
If the printed circuit board is arranged in an inclined manner to maintain optical axis parallelism, then the optical axis alignment is improved, but the system size increases making integration difficult
Solution Approach 1:
By segmenting the motherboard into tiltable sections connected by a pivot axis, the system achieves optical axis parallelism through compact angular adjustment rather than extending the overall system structure, thus maintaining small size while ensuring proper alignment.
3Manufacturing precision
If a flexible electrical sheet is used to connect inclined printed circuit boards, then the optical axis adjustment is achieved, but the assembly cost increases
Solution Approach 1:
The rigid segmented structure with pivot axis connection eliminates the need for expensive flexible electrical sheets, achieving optical axis angle adjustment through mechanical tilting while maintaining cost-effective rigid circuit board assembly.
Solution Approach 2:
The invention replaces expensive flexible electrical sheet components with a simpler, more cost-effective rigid pivot connection mechanism that achieves the same functional result of optical axis adjustment without requiring costly flexible connectivity solutions.
