Data Cable Junction Box With Front-Access Sliding Clamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection boxes, particularly flush-mounted or cavity wall boxes, face challenges in handling and inserting data cables due to limited space and the complexity of clamping mechanisms, which require manual manipulation from behind, making the process laborious and difficult.
Innovation Solution
A connection box design featuring a clamping device that is displaceable along the central axis via a rail guide, allowing for linear movement without tilting, and a clamping screw actuated from the front, enabling easier cable insertion and clamping without the need for manual manipulation from behind, along with a rail guide that secures the clamping device in place, ensuring stability and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clamping device is provided on the lower housing part base to clamp the data cable, then the cable can be securely fixed, but the installation becomes complex and laborious due to limited space and the need for manual manipulation from behind
Solution Approach 1:
The clamping device is made displaceable along the central axis instead of being fixed, allowing it to be moved into position from the front rather than requiring manipulation from behind. The displaceable clamping device can be positioned at different locations along the central axis to facilitate easier cable insertion and clamping from the accessible front side.
Solution Approach 2:
The clamping device is designed to be displaceable along the central axis of the housing rather than being statically fixed. This dynamic positioning capability allows the clamping device to be moved to optimal positions for cable clamping, improving both accessibility during installation and adaptability to different cable configurations.
2Device complexity
If the clamping device is fixed on the lower housing part base, then the structure is simple, but the available space for inserting the data cable is very limited
Solution Approach 1:
The clamping device is designed with displacability along the central axis, transforming it from a fixed component to a movable one. This allows the clamping device to be repositioned to create adequate insertion space, resolving the conflict between structural simplicity and available insertion area.
Solution Approach 2:
The clamping device is separated from the fixed base structure and made independently displaceable along the central axis. This segmentation allows the clamping function to be decoupled from the housing structure, enabling movement to optimize insertion space without compromising overall structural integrity.
3Reliability
If manual manipulation from behind is required to operate the clamping means, then the clamping can be secure, but the operation becomes difficult in confined spaces
Solution Approach 1:
Instead of requiring manipulation from behind the housing, the clamping device is made accessible from the front by allowing it to be displaced along the central axis. This inversion of the operation direction enables secure clamping to be achieved through front-side access, which is much more accessible in confined installation spaces.
Solution Approach 2:
The displaceable clamping device acts as an intermediary between the cable and the fixed housing structure. It can be moved into position from the front to perform the clamping function, serving as a mediator that enables secure fixation without requiring direct manipulation from behind the housing.
