Wall Connection Box With Rotatable Front-Access Height Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mounted connection box units lack flexibility and ease of use in terms of adjustable axial height and accessibility for fixing the functional surface body to the base section, which complicates installation and maintenance, especially when already mounted on a wall.
Innovation Solution
A rotatable connecting body with an actuation interface located on the functional surface body, allowing for tool-free adjustment between release and fixing positions, and a sleeve element extending through the base section for flexible positioning of the functional surface body relative to the base section, enabling easy axial adjustment and fixing either in front of or behind the base section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the functional surface body is fixed to the base section at a specific axial height, then the connection box unit can be mounted on a wall, but the axial height cannot be adjusted after installation
Solution Approach 1:
The connection device transitions from a static fixed-position design to a dynamic adjustable design. The connecting body can be moved axially along the sleeve element and locked at different positions, allowing the functional surface body to be positioned at various axial heights relative to the base section, thus enabling adaptability while maintaining manageable complexity through a straightforward mechanical adjustment mechanism.
2Ease of operation
If the connection device requires tools for adjustment, then the fixing can be secure, but the adjustment process becomes complicated and time-consuming
Solution Approach 1:
The connecting body incorporates an actuating interface that enables tool-free adjustment by the user. The design allows manual operation to move the connecting body between release and fixing positions, eliminating the need for external tools while maintaining secure fixing through the engagement of the connecting body with the connection structure at the desired axial position.
3Ease of operation
If the actuation interface is located on the base section, then the connecting mechanism can be simple, but the interface is inaccessible after wall installation
Solution Approach 1:
The actuating interface is repositioned from the base section to the functional surface body, changing its spatial location to a more accessible dimension. This allows users to reach and operate the interface after the connection box unit is installed on a wall, as the functional surface body extends toward the wall surface, making the interface accessible from the front rather than requiring access from the rear base section.
