Solution Overview
Problem
Camera module designs face challenges in reducing size as the number of electronic components increases, with existing configurations not efficiently utilizing space and potentially interfering with the photosensitive chip's light-sensing path.
Innovation Solution
The electronic components are strategically arranged on the inner surface of the bracket's side wall, using conductive adhesive layers or flexible printed circuit boards to establish electrical connections, allowing for compact placement without additional fixing structures and minimizing interference with the photosensitive chip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If electronic components are arranged around the photosensitive chip on the PCB, then electrical connections can be established, but the camera module size cannot be reduced despite increasing component density
Solution Approach 1:
The patent transitions from planar arrangement of electronic components on the PCB to three-dimensional arrangement on the bracket structure. The bracket provides vertical and lateral surfaces for mounting components, enabling spatial utilization beyond the two-dimensional PCB plane. This dimensional transition allows compact integration while maintaining electrical connectivity through flexible circuits and conductive adhesives.
Solution Approach 2:
The bracket serves as an intermediary structure between the PCB and electronic components. Instead of directly mounting components on the PCB, the patent uses the bracket as a intermediate platform that holds components and provides mounting surfaces. This intermediary approach enables flexible component placement and simplifies electrical connections through the use of flexible printed circuits and conductive adhesive layers.
2Reliability
If additional fixing structures are used to secure electronic components, then component stability is improved, but assembly complexity and space requirements increase
Solution Approach 1:
The bracket structure provides self-service fixation for electronic components through its inherent geometric features. The bracket's side walls and mounting surfaces naturally constrain components in place without requiring additional external fixing structures. The integration of mounting functions into the bracket's basic structure eliminates the need for separate fastening elements, simplifying both design and assembly.
Solution Approach 2:
The patent merges the support and fixation functions into the single bracket structure. Rather than having separate support elements and fixing elements, the bracket simultaneously provides both functions through its integrated design. The bracket holds electronic components while its structural features provide inherent stabilization, combining multiple functions into one component.
3Volume of moving object
If electronic components are placed close to the photosensitive chip, then space utilization is improved, but light interference may occur
Solution Approach 1:
The patent extracts electronic components from the immediate vicinity of the photosensitive chip's light path. By placing components on the bracket structure rather than on the PCB near the chip, the design removes potential light-interfering elements from the critical optical path. This separation maintains compact overall size while eliminating light interference risks.
