Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of pixels in image sensors within camera modules for vehicles leads to larger element components, making it difficult to mount all components on a single PCB, resulting in a longer camera module and compromising miniaturization and reliability.
Innovation Solution
A camera module design that incorporates a PCB with an image sensor and connectors, along with subsidiary substrates connected at predetermined angles, housed within a modular structure to minimize size and allow for various functional modules, using flexible connecting cables and accommodating grooves to optimize space usage.

Engineering Contradiction Analysis
1Quantity of substance
If multiple PCBs are formed by being laminated to accommodate increased number of pixels and larger element components, then the camera module can house all necessary components, but the entire length of the camera module becomes longer
Solution Approach 1:
The subsidiary substrate is connected to the PCB at a predetermined angle (e.g., 45 degrees) rather than being laminated parallel to the PCB. This angular connection allows the subsidiary substrate to be arranged in a different spatial dimension, effectively utilizing three-dimensional space within the housing instead of extending the length in a single direction. The accommodating groove in the housing further constrains the subsidiary substrate to a specific angular position, enabling compact integration of multiple substrates without increasing the overall length of the camera module.
2Volume of moving object
If subsidiary substrates are connected at an angle to the PCB, then the camera module achieves miniaturization, but the connector arrangement becomes more complex
Solution Approach 1:
The camera module is divided into separate functional substrates (PCB and subsidiary substrate) that are connected at an angle. This segmentation allows each substrate to be optimized independently for its specific function while the angular connection enables compact three-dimensional arrangement. The housing with accommodating grooves provides structural guidance that simplifies the assembly process despite the angular configuration.
3Volume of moving object
If the camera module is miniaturized by reducing height and length, then space is saved for other components, but the mounting space for PCBs and control modules becomes limited
Solution Approach 1:
By connecting the subsidiary substrate at a predetermined angle to the PCB, the design transitions from a two-dimensional planar arrangement to a three-dimensional angular configuration. This allows components to be distributed in multiple spatial dimensions within the housing, effectively increasing the usable mounting area without increasing the overall footprint or height of the camera module.
