Camera Module Housing Integrated Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing camera module attachment methods for motor vehicles are costly and time-consuming due to the need for threaded sections, which increases production time and expenses.
Innovation Solution
A camera module with a one-piece camera housing featuring integrated fastening sections and a retaining ring, made from plastic or metal, that allows for secure attachment to the vehicle without the need for additional threading, using film hinges and self-locking mechanisms to ensure reliable positioning and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded sections are provided for attaching the camera module, then the camera module can be securely fastened to the motor vehicle, but the tool for producing the exterior mirror housing becomes expensive and production time increases
Solution Approach 1:
The fastening section is integrated directly into the camera housing as a one-piece structure, merging the housing and fastening elements into a single component. This eliminates the need for separate threaded sections and complex assembly steps, thereby reducing production time while maintaining secure fastening capability through the integrated design
Solution Approach 2:
The threading operation is extracted from the production process by designing the fastening section with pre-formed threading capability that does not require tap production. The fastening sections are designed to be directly attachable without requiring the tool to produce threads, thereby eliminating the costly and time-consuming threading step

3Productivity
If the camera housing is made as a one-piece structure with integrated fastening sections, then manufacturing and assembly time are reduced, but the complexity of the housing design increases
Solution Approach 1:
The one-piece camera housing is divided into functional segments: the main housing body and integrated fastening sections. The fastening sections are designed as distinct functional elements within the one-piece structure, allowing for modular design thinking that simplifies the overall complexity while maintaining the integration benefits for reduced assembly time
