Adjustable Electrical Box Support for Metal Studs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical boxes secured to metal studs require additional support to prevent movement, and existing cable support brackets are often damaged during shipping due to their fixed configuration, necessitating multiple sized supports or pre-measured installations to accommodate various stud sizes.
Innovation Solution
An adjustable electrical box assembly with a support system that can be configured to different sizes by bending appendages and a cable support bracket that moves from a shipping position to an installed position, minimizing damage during shipping and accommodating various stud depths without the need for multiple brackets or pre-measured installations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed cable support bracket is connected during manufacture, then the electrical box is ready for installation, but the bracket can be damaged during shipping
Solution Approach 1:
The cable support bracket is designed to be movable rather than fixed during shipping. The bracket can be positioned in different configurations - extended outward during installation and retracted or positioned inward during shipping to avoid damage. This dynamic positioning resolves the contradiction between being ready for installation and avoiding shipping damage.
Solution Approach 2:
The cable support bracket is designed as a separate, detachable component that can be connected or disconnected independently. This allows the bracket to be separated from the electrical box during shipping to prevent damage, and then attached during installation to provide support functionality.
2Adaptability or versatility
If multiple sized supports are provided, then various stud sizes can be accommodated, but the device complexity increases
Solution Approach 1:
The support bracket incorporates adjustable elements that can be repositioned to accommodate different stud depths. Instead of providing multiple fixed-size brackets, a single bracket with movable and adjustable components can adapt to various stud sizes (2.5 inch, 3.5 inch, 3.625 inch, 4 inch, 5.5 inch, and 6 inch), reducing the number of parts needed while maintaining versatility.
Solution Approach 2:
The electrical box assembly includes a universal support bracket design that can serve multiple stud size requirements through its adjustable and reconfigurable features. The bracket system incorporates movable appendages and adjustable positioning mechanisms that allow one bracket to perform the function of multiple fixed-size brackets, eliminating the need to carry multiple different bracket types.
3Ease of manufacture
If the support is fixed in size, then manufacturing is simplified, but it cannot accommodate various stud sizes
Solution Approach 1:
The support bracket incorporates movable and adjustable components that allow it to change its effective size and configuration. The bracket includes repositionable appendages and adjustable positioning mechanisms that enable a single standardized bracket design to adapt to various stud depths during installation, maintaining manufacturing simplicity while providing versatility.
