Wall Connection Box Fixing for Flush-Mount Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mounted connection box units lack flexibility in axial height adjustment and accessibility for fixing the functional surface body after installation, which complicates the attachment and sealing processes, especially when trying to achieve flush mounting in various applications.
Innovation Solution
The connecting device features an actuation interface located on the side of the functional surface body facing away from the base section, allowing for easy axial adjustment and rotation of the connecting body between release and fixed positions, enabling flexible fixing of the functional surface body at different axial heights relative to the base section, even after the box unit is installed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the actuation interface is located on the base section side, then the connecting device can be operated during installation, but the base section becomes obstructed and accessibility is reduced after installation
Solution Approach 1:
The actuation interface is moved from the base section to the functional surface body, utilizing a different spatial dimension. This allows the interface to be accessible from the front side of the device while the base section remains unobstructed for wall mounting and installation purposes.
2Adaptability or versatility
If the functional surface body is fixed at a specific axial height, then the structure is simplified, but flexibility in adjustment is reduced
Solution Approach 1:
The connection device incorporates a rotatable connecting body that can be positioned at different axial heights along the base section and secured in place. This dynamic adjustment mechanism allows the functional surface body to be fixed at multiple axial positions, providing flexibility while maintaining structural integrity through the rotation-locking system.
3Ease of operation
If the connecting body is made accessible from the front side, then post-installation adjustment is enabled, but the connection structure becomes more complex
Solution Approach 1:
The connection device is segmented into distinct functional components: the base section with connection structures, the functional surface body with the actuation interface, and the connecting body that rotates to lock them together. This segmentation allows the actuation interface to be accessible from the front while maintaining a relatively simple overall structure.
