Camera Power Board Layout for Compact External Connector Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image pickup apparatus designs face challenges in minimizing size increases due to the placement of external connectors, particularly in directions perpendicular and parallel to the optical axis, leading to overall apparatus enlargement.
Innovation Solution
The design incorporates a power supply circuit board with specific board portions and an external connector placement that avoids overlap with the optical axis, allowing for efficient layout within the apparatus dimensions, including a first board portion perpendicular to the optical axis and a second board portion with the connector mounted on it, positioned to minimize size expansion in both directions.

Engineering Contradiction Analysis
1Area of moving object
If the external connector is mounted on the power supply circuit board overlapping other components in the optical axis direction, then the size in the direction perpendicular to the optical axis is suppressed, but the dimension in the optical axis direction becomes significantly large
Solution Approach 1:
The connector mounting surface is positioned in a different spatial dimension (laterally offset from the optical axis) rather than overlapping in the optical axis direction. This dimensional repositioning allows the connector to be integrated without extending the optical axis length, resolving the contradiction between suppressing perpendicular size and maintaining compact optical axis dimension.
Solution Approach 2:
The power supply circuit board is divided into functionally independent regions: a connector mounting surface positioned laterally offset from the optical axis, and a component mounting surface positioned along the optical axis. This segmentation allows each surface to serve its purpose without interfering with the other, enabling compact integration in both directions.
2Length of moving object
If the external connector is positioned to minimize optical axis dimension, then the optical axis direction size is suppressed, but the size in the direction perpendicular to the optical axis increases
Solution Approach 1:
The connector is repositioned from the optical axis dimension to a lateral dimension, creating a three-dimensional layout where the connector mounting surface and component mounting surface occupy different spatial zones. This allows minimization of optical axis dimension while containing perpendicular size through strategic positioning within the available lateral space.
Solution Approach 2:
Different regions of the power supply circuit board are assigned different functional qualities: the connector mounting surface is positioned laterally offset to minimize optical axis impact, while the component mounting surface is positioned along the optical axis for functional integration. This local differentiation optimizes the overall apparatus size in both directions.
