Folded Circuit Board Device for Compact Image Capturing Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing modules have a large volume due to the size of the circuit board required to accommodate various functional modules, making them less compact.
Innovation Solution
A circuit board device with a polyhedral support frame and a circuit board unit comprising two rigid boards connected by flexible boards, allowing the boards to fold and be positioned on different sides of the frame, thereby optimizing space utilization and reducing volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large circuit board is used to accommodate multiple functional modules, then the functionality is improved, but the volume of the image capturing module increases
Solution Approach 1:
The circuit board is divided into multiple independent rigid boards (first rigid board, second rigid board, third rigid board, fourth rigid board) that can be folded and positioned on different sides of the support frame. This segmentation allows functional modules to be distributed across multiple boards rather than requiring a single large board, thereby reducing the overall volume while maintaining full functionality.
Solution Approach 2:
The rigid boards are folded and disposed on different sides of the polyhedral support frame, utilizing three-dimensional space instead of a single planar surface. This spatial arrangement allows multiple functional modules to be accommodated in a compact volume by distributing them across different faces of the polyhedral structure.
2Volume of stationary object
If the circuit board size is reduced to minimize volume, then the volume is improved, but the space to accommodate functional modules is reduced
Solution Approach 1:
By folding the rigid boards and positioning them on different sides of the polyhedral support frame, the design transitions from a two-dimensional planar layout to a three-dimensional spatial arrangement. This allows the total functional area to be distributed across multiple surfaces, effectively increasing the available area within a reduced volume.
Solution Approach 2:
The multiple rigid boards are nested within the polyhedral support frame structure, with each board positioned on a different face or side. This nested arrangement maximizes the utilization of the three-dimensional space within the compact volume, allowing sufficient area for all functional modules without increasing the external dimensions.
