Bracket and Sleeve Assembly for Wall Substrate Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing electrical components in building walls are time-consuming and inefficient, particularly in accurately locating and cutting openings in the wall substrate to accommodate electrical boxes, as they require manual adjustment for different substrate thicknesses and may not ensure the device is flush and parallel to the wall surface.
Innovation Solution
A flange assembly that couples with the wall structure, featuring a planar surface for tight contact and mating elements to maintain the electrical device's alignment, along with a removable sleeve for guiding the cutting of the substrate opening, ensuring secure and accurate installation of both line voltage and low voltage devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional manual methods are used to locate and cut openings in wall substrate, then installation can be completed, but the process is time-consuming and labor-intensive
Solution Approach 1:
The flange is pre-attached to the electrical box before the wall substrate is installed. This preliminary positioning allows the opening to be cut precisely to the required dimensions without time-consuming manual measurement and adjustment during the installation process, directly improving productivity and reducing time loss.
Solution Approach 2:
The flange acts as an intermediary component between the electrical box and the wall substrate. It provides a standardized interface that simplifies the installation process by eliminating the need for manual localization and cutting adjustments, thereby increasing installation speed and reducing time consumption.
2Manufacturing precision
If the electrical box is mounted flush with the wall substrate outer surface, then code compliance is achieved, but accurate positioning requires manual adjustment for different substrate thicknesses
Solution Approach 1:
The flange is designed with a standardized structure that can accommodate various wall substrate thicknesses. Its multi-functional design allows it to serve as both a mounting surface and a positioning reference, eliminating the need for manual adjustment when different substrate thicknesses are used, thereby improving ease of operation while maintaining positioning accuracy.
Solution Approach 2:
The flange's design incorporates parameter variations that allow it to adapt to different wall substrate thicknesses. By changing the flange's dimensional parameters or selecting from standardized flange sizes, accurate positioning is achieved across different substrate thicknesses without requiring manual adjustment, thus improving ease of operation while maintaining manufacturing precision.
3Ease of operation
If the electrical box outer edge is not square with the wall substrate, then installation may be faster, but the device facing cannot be ensured flush with the substrate plane
Solution Approach 1:
The flange is pre-attached to the electrical box with its outer edge squared to the substrate plane before installation. This preliminary squaring action ensures that when the flange is mounted to the substrate, the device facing is automatically aligned flush with the substrate plane, maintaining manufacturing precision while simplifying the installation process.
Solution Approach 2:
The flange serves as an intermediary that transfers the squared alignment from the substrate plane to the electrical box. By attaching the box to the flange rather than directly to the substrate, the squared alignment is maintained throughout the assembly, ensuring flush alignment of the device facing while easing the installation process.

AI summary
An assembly includes a bracket mountable directly to a wall. An inner periphery of the bracket defines an opening in the wall substrate. A resilient element, cantilevered from an outer side surface of the sleeve, is retained by a barbed element at the inner periphery of the bracket.
