Sliding Electrical Box Assembly for Adjustable Depth Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical box systems lack the ability to be easily adjusted to different depths relative to support structures, which can lead to installation challenges and inefficiencies.
Innovation Solution
An adjustable-height electrical box assembly comprising an outer box and an inner box, where the inner box is slidably received into the outer box and features guide protrusions to guide its movement, allowing for adjustment of the box's depth relative to the support structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an electrical box is designed with fixed depth, then manufacturing and installation are simpler, but adaptability to different support structure depths is reduced
Solution Approach 1:
The electrical box is divided into two separate components: an outer box and an inner box. The inner box can be positioned at different depths within the outer box, allowing the assembly to adapt to various support structure depths while keeping each individual box component relatively simple in design.
Solution Approach 2:
The inner box is designed to be movable within the outer box through a sliding mechanism with guide protrusions. This dynamic configuration allows the electrical box assembly to adjust its effective depth according to installation requirements, transforming a static fixed-depth design into an adjustable system.
2Ease of operation
If guide protrusions are added to enable sliding movement, then adjustability is improved, but manufacturing complexity increases
Solution Approach 1:
The guidance function is segmented into discrete guide protrusions located at specific corners of the inner box, rather than requiring complex continuous guidance mechanisms. This simplifies manufacturing while still providing effective directional control for the sliding movement.
Solution Approach 2:
The guide protrusions on the inner box automatically engage with corresponding features in the outer box during assembly, self-aligning and guiding the inner box into the correct position without requiring additional alignment tools or complex adjustment procedures.
3Adaptability or versatility
If the inner box is made slidable within the outer box, then adaptability to different depths is improved, but stability may be reduced
Solution Approach 1:
The guide protrusions act as intermediary elements between the inner box and outer box. These protrusions provide controlled contact points that guide the sliding movement while maintaining stable engagement, preventing excessive movement or misalignment during adjustment.
Solution Approach 2:
The sliding mechanism with guide protrusions provides a controlled dynamic system where the inner box can move to different positions but remains securely engaged at each position. The guide protrusions ensure that movement is restricted to the intended linear path, maintaining stability while enabling adjustability.

AI summary
An assembly for an adjustable-depth electrical box can include an outer box and an inner box slidably received into the outer box. The outer box can include outer sidewalls extending from a base end to an open end of the outer box. The inner box can include inner sidewalls and guide protrusions. The inner sidewalls can include a first set of opposed inner sidewalls and a second set of opposed inner sidewalls, and the guide protrusions can include at least one guide protrusion, respectively, on each inner sidewall of the first set of opposed inner sidewalls and on each inner sidewall of the second set of opposed inner sidewalls.
