Segmented Camera Housing Retaining Ring with Film Hinges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera housings for motor vehicles require high assembly effort when connecting the camera, are not securely guided, and often lack splash-proofing.
Innovation Solution
A camera housing with a housing base body and a one-piece retaining ring formed by segmented shells attached via film hinges, which pivot to securely hold the camera and provide splash protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera is inserted into a housing with guide ribs and a tab covering the entire width, then the camera can be attached to the housing, but the assembly work is complex and the locking is not secure due to play in the guide
Solution Approach 1:
The retaining ring is divided into two segmental shells that can be pivoted independently. This segmentation allows each shell to engage with corresponding features on the camera body, eliminating play while simplifying the overall assembly process. The segments can be opened for easy installation and locked securely when closed.
Solution Approach 2:
The retaining ring shells are designed to be movable rather than fixed, allowing them to pivot into position during assembly and then lock securely. This dynamic design enables simple assembly operations while achieving reliable, play-free locking of the camera in the housing.
2Ease of operation
If spring clips extend from the bottom of the case to the top edge of the camera, then the camera can be secured, but the camera is not securely guided and is not splash-proof
Solution Approach 1:
The segmental retaining ring shells provide flexible yet secure engagement with the camera. When closed, they form a complete protective barrier that secures the camera firmly in position and provides splash protection, while allowing for simple assembly through pivoting motion.
Solution Approach 2:
The retaining ring structure combines multiple functions into a single component: it secures the camera, provides precise guidance to eliminate play, and creates a splash-proof seal. This merged design replaces the inadequate spring clip system with a multi-functional solution.
3Ease of manufacture
If the camera housing uses a tab to cover the entire width for locking, then the camera can be attached, but the locking is not secure due to play and the structure is complex
Solution Approach 1:
Instead of a single wide tab, the locking structure is segmented into two independent shells that pivot to engage with the camera. This segmentation simplifies the housing structure while achieving secure, play-free locking through precise engagement of each segment with corresponding features on the camera body.
