Electrical Box With Dual Fastener Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical boxes can only be mounted using either nails or screws, limiting installer flexibility and increasing inventory and installation time, and often lose fasteners, leading to inefficient installation processes.
Innovation Solution
An electrical box design featuring both nail and screw supports, allowing secure attachment with either type of fastener and preventing accidental removal, along with mounting holes for low voltage frames or brackets, enabling versatile installation options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical boxes are designed to accept only one type of fastener (screw or nail), then the mounting structure is simple, but the installer flexibility and inventory efficiency deteriorate
Solution Approach 1:
The electrical box is designed with dual fastener support capabilities, incorporating both nail supports (with recesses to receive nail heads) and screw supports (with threaded holes) on its mounting surface. This universal design allows the same electrical box to be mounted using either nails or screws, eliminating the need for separate box types and improving installer flexibility without significantly complicating the overall box structure.
2Productivity
If mounting fasteners are provided separately from the electrical box, then the box structure is simple, but the installation time increases due to fastener location and potential loss
Solution Approach 1:
The electrical box integrates mounting fasteners directly into its structure by incorporating recesses to receive nail heads and threaded holes for screw retention. This merging of the fastener storage function into the box itself ensures fasteners remain attached during handling and installation, eliminating the need for separate fastener packages and preventing fastener loss, thereby improving installation speed.
3Adaptability or versatility
If the electrical box has only basic mounting features, then the manufacturing cost is low, but the ability to accommodate low voltage frames and additional mounting options is limited
Solution Approach 1:
The electrical box incorporates distinct, segmented mounting features including separate nail supports with recesses, screw supports with threaded holes, and additional mounting holes positioned at different locations. This segmentation of mounting functions into discrete, standardized features allows for versatile accommodation of various mounting options and low voltage frames while maintaining ease of manufacture through modular design elements.

AI summary
An electrical box assembly adapted to receive two different types of fasteners, such as screws and nails. The electrical box assembly has a base with an outer edge. A wall extends outwardly from the outer edge of the base that forms a cavity therein. A first fastener support on the wall is adapted to receive a first fastener. A second fastener support on the wall is adapted to receive a second fastener, wherein the first and second fasteners are different types of fasteners.
