Cable Assembly Planar Fixing for Compact Imaging Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable assemblies for endoscopes and imaging apparatuses face challenges in downsizing due to the length of hard connection terminal parts, which hinder efficient connection and arrangement of cables to circuit boards.
Innovation Solution
A cable assembly with a cable fixing member that arranges the distal end of cables along its facing surface, exposing side surfaces of core and outer conductors at predetermined positions for connection, allowing for non-orthogonal arrangement while maintaining a compact form through the formation of connection parts via metal film plating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional array block with orthogonal connection is used, then the connection structure is simple, but the device size cannot be reduced and flexible arrangement is limited
Solution Approach 1:
The patent transitions from orthogonal connection (one-dimensional approach) to planar arrangement where cables are disposed parallel to the facing surface (two-dimensional approach). This dimensional change allows for compact layout and flexible arrangement while reducing the projection area and enabling smaller device size.
Solution Approach 2:
The cable fixing member is divided into multiple regions with different functions: cable fixing portions for securing cables, connection portions for exposing conductor surfaces, and flat portions for structural support. This segmentation allows each part to perform its specific function efficiently, simplifying the overall connection structure while enabling compact design.
2Volume of moving object
If the cable assembly is arranged non-orthogonally to reduce space, then compact arrangement is achieved, but reliable electrical connection becomes difficult
Solution Approach 1:
The cable fixing member exhibits local quality variations: the cable fixing portions have structures suitable for securing cables, the connection portions have exposed conductor surfaces for reliable electrical contact, and the flat portions provide structural stability. This localized functional differentiation ensures reliable electrical connection at the connection portions while allowing non-orthogonal, compact arrangement of the overall assembly.
