Offset Sidewall Housing for Cable Strain Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera designs with detachable cables are prone to damage from pulling forces during connection or disconnection, and existing cable strain relief solutions are bulky and complex to install.
Innovation Solution
A compact housing design with two separate parts that form a recessed opening to secure cables, featuring offset sidewalls to provide a strong cable strain relief function without separating the housing parts, and optionally incorporating sealing features to prevent unwanted forces from being transmitted to the cable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a cable connection is made detachable or with a short cable extending from the electric circuitry, then the camera size is minimized and connection flexibility is improved, but the cable connection becomes vulnerable to damage from pulling forces during connection or disconnection
Solution Approach 1:
The housing is divided into a first housing part and a second housing part that can be separated from each other. The cable passes through an opening formed at the interface between these two parts, allowing the cable to be secured at the housing level rather than at the vulnerable circuitry connection point. This segmentation enables the cable strain relief function to be decoupled from the electrical connection, protecting the connection while maintaining compact camera design.
2Reliability
If an elaborate meandering cable pattern with multiple hooks is used for cable strain relief, then cable protection is improved, but the device becomes bulky and complex to install
Solution Approach 1:
The cable strain relief function is merged into the housing structure itself. The opening formed by the interface between the first and second housing parts inherently provides cable securing through its geometric configuration. The offset sidewalls create a natural cable retention mechanism without requiring separate hooks or elaborate mounting structures. This integration eliminates the need for complex external cable management components while maintaining effective strain relief.
3Strength
If the opening is formed by offset sidewalls in the first and second housing parts, then cable strain relief strength is improved, but the housing assembly becomes more complex
Solution Approach 1:
The sidewalls of the opening are deliberately positioned at offset locations in the first and second housing parts rather than being symmetrically aligned. This asymmetric arrangement creates a mechanical interlocking effect that provides strong cable strain relief. The offset configuration ensures that pulling forces on the cable are distributed across both housing parts, preventing the cable from being pulled through the opening while maintaining a relatively simple housing assembly structure.

AI summary
A housing for enclosing an electric circuitry and for providing a cable strain relief function to a cable extending from the electric circuitry and out of the housing and a camera comprising such a housing is disclosed. The housing comprises a first part with a first recess and a second part with a second recess, wherein the first and second recesses each has a first sidewall portion, a bottom portion and a second sidewall portion, the first and second sidewall portions of the first recess being arranged offset to each other in a cable exit direction.
