Image Capturing Device Cable Fixation via Nested Restriction Bushing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capturing devices with cable fastening mechanisms are too large to be mounted in limited spaces, such as rearview mirrors, due to the size increase caused by external cable fastening mechanisms, and lack effective waterproof and dust-proof solutions.
Innovation Solution
An image capturing device design featuring a base with a through hole, a restriction bushing that surrounds the cable, and a sealing material that covers the bushing and cable, providing a compact form factor and enhanced waterproof and dust-proof capabilities, with the bushing and sealing material affixed to the base to prevent separation and improve sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable fastening mechanism is disposed on the outside of the base to affix the cable, then the cable is prevented from being broken or separated, but the size of the image capturing device increases and it cannot be mounted in limited spaces
Solution Approach 1:
The restriction bushing is inserted into the base through hole, nesting the cable fixation structure within the base itself rather than adding an external mechanism. The bushing fits inside the through hole, creating a compact nested arrangement that maintains cable security without increasing overall device volume.
Solution Approach 2:
The cable fastening function is merged with the base structure by integrating the restriction bushing into the base through hole. Instead of a separate external fastening mechanism, the bushing becomes part of the base assembly, combining the base and cable fixation functions into a single integrated structure.
2Reliability
If a conventional cable fastening mechanism is used, then the cable is secured, but the device size increases and mounting in limited spaces becomes impossible
Solution Approach 1:
The restriction bushing is nested within the base through hole, creating a compact configuration that maintains cable security while reducing the overall footprint. This nested arrangement allows the device to adapt to limited mounting spaces such as rearview mirrors.
Solution Approach 2:
The cable fixation mechanism is merged with the base structure, eliminating the need for separate external fastening components. This integration improves mounting adaptability by reducing the number of external parts and simplifying the overall device configuration for compact installation.
3Reliability
If external cable fastening mechanisms are used, then the cable is protected, but the device complexity and size increase
Solution Approach 1:
The restriction bushing is nested within the base through hole, creating a simple nested structure that protects the cable without adding complex external fastening mechanisms. The bushing's internal ribs provide cable protection through a simple geometric feature rather than a complex mechanical system.
Solution Approach 2:
The cable protection function is merged with the base structure through the integrated restriction bushing. Instead of separate protection mechanisms, the bushing becomes an integral part of the base, simplifying the overall device complexity while maintaining cable protection capabilities.
