Electrical Box Mounting With Tool-Free Stud Conduit Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electrical conduit systems are cumbersome to install and require the use of tools, making it difficult to protect wires from external damage and efficiently install electrical conduit in structures.
Innovation Solution
The development of a stud wire protector and electrical conduit coupling system, which includes hollow cylindrical members with press-fitting and tapered fittings, allowing for tool-free installation and protection of wires by inserting the system into pre-drilled holes in studs, and using conduit couplers with springs to secure the conduit in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electrical conduit systems are used, then wire protection from external damage is achieved, but installation becomes cumbersome and requires tools
Solution Approach 1:
The conduit system is divided into modular sections that can be independently installed between studs. Each segment includes mounting elements and conduit portions that can be assembled without tools, allowing progressive installation along the wall structure.
Solution Approach 2:
Mounting elements are pre-attached to the conduit sections during manufacturing. The conduit portions are pre-cut to standard lengths, and all necessary components are pre-assembled into complete kits, eliminating the need for on-site tool usage and complex assembly procedures.
2Reliability
If traditional electrical conduit systems are used, then complete wire protection is achieved, but installation time increases
Solution Approach 1:
All mounting elements, conduit sections, and hardware are pre-assembled into complete installation kits before delivery to the job site. This preliminary preparation eliminates time-consuming on-site assembly operations and allows installers to simply attach pre-assembled units to the structure.
Solution Approach 2:
The system is segmented into standardized modules that can be quickly installed between adjacent studs. Each module is self-contained and requires minimal connection steps, enabling parallel installation across multiple wall sections simultaneously.
3Productivity
If simple installation method is used, then installation speed increases, but protection against external damage may be compromised
Solution Approach 1:
The conduit portions use curved or angled sections rather than only straight segments, allowing the conduit to naturally follow the contours of wall framing and stud configurations. This curved geometry provides better protection by accommodating structural variations while maintaining continuous wire coverage.
Solution Approach 2:
The conduit sections are designed to nest within or connect to mounting elements and structural features of the building framework. This nested integration ensures secure positioning and continuous protection while simplifying the attachment process to existing structural components.

AI summary
A method for mounting an electrical box to a structural element of a building includes drilling an opening in a structural element, and passing a tubular portion associated with an electrical box through the opening in the structural element. The tubular portion is locked in position with respect to the structural element.
