Installation Box Clamping Screw Layout to Prevent Shoe Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current installation box assemblies have limitations in workability, as they are suited for either thin or thick hollow walls, and there is a risk of losing the clamping shoe during installation or uninstallation due to inadequate feedback from screwing tools, leading to incorrect assembly or loss of the clamping device.
Innovation Solution
The installation box assembly features a clamping device with a screw member having distinct sections with different thread configurations, preventing the nut part from meshing with the wrong section of the screw member, thus reducing the risk of losing the clamping shoe and allowing for easy assembly and disassembly, and includes a design suitable for both thin and thick hollow walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single continuous threaded screw member is used, then the clamping device can be assembled and disassembled easily, but the clamping shoe can be accidentally screwed off the screw and lost during installation or uninstallation
Solution Approach 1:
The screw member is divided into three distinct sections: a first threaded section at the tip end, a middle unthreaded section, and a second threaded section at the head end. The clamping shoe's nut part has an inner thread with a greater minor diameter than the middle section's outer diameter, preventing the nut from engaging the middle section. This segmentation ensures that during disassembly, the nut can only travel along the threaded sections and cannot be accidentally screwed off the screw member, eliminating the risk of losing the clamping shoe while maintaining ease of operation.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the reliability of the installation process by preventing the clamping shoe from being lost and allows for easy assembly and disassembly, while accommodating a wider range of hollow wall thicknesses, improving the overall usability and versatility of the installation box assembly.
Implementation Method 1
a screw member extending parallel to the longitudinal axis, the screw member having a longitudinal screw axis, wherein in an assembled state of the installation box the screw member is supported by the first bearing and the second bearing, the screw member comprising a tip end located at the first end of the side wall, a head end located at the free, second end of the side wall
