Adjustable Inlet Fitting for Electrical Box Sheath Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recessed electrical boxes have limited interior volume, making it difficult to accommodate both electrical equipment mechanisms and routing sheaths, requiring repetitive and costly installation of end pieces for multiple sheaths, which complicates the installation process and interferes with wall insertion.
Innovation Solution
A connector with an end piece that allows connection of two routing sheaths in a juxtaposed position, facilitating the connection of multiple sheaths with a single end piece attachment, enabling easier installation and orientation of sheaths to avoid interference during wall insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single end piece is used to connect one routing sheath, then the installation is simple, but multiple separate end pieces are required for multiple sheaths, increasing complexity and cost
Solution Approach 1:
The patent combines multiple routing sheath connections into a single integrated end piece structure. The end piece includes multiple ducts that can respectively receive and secure multiple routing sheaths, eliminating the need for multiple separate end pieces and simplifying the overall installation process
Solution Approach 2:
The end piece is designed with multi-functionality to accommodate various routing sheaths through its multiple ducts. This universal structure can handle different cable routing requirements while maintaining a single-component solution, reducing both complexity and installation time
2Ease of operation
If routing sheaths are connected on opposite sides of the box, then connection is achieved, but wall insertion becomes difficult due to interference
Solution Approach 1:
The patent merges multiple routing sheath connections to exit from the same side of the electrical box through a single end piece. This consolidation eliminates the interference problem that occurs when sheaths exit from opposite sides, making wall insertion straightforward while maintaining organized cable management
3Volume of stationary object
If the interior volume of the box is reduced to standard sizes, then the box fits standard openings, but there is insufficient space to accommodate equipment mechanisms and routing sheaths
Solution Approach 1:
The patent extends the routing sheath connections outward from the electrical box through ducts in the end piece. This dimensional extension allows routing sheaths to be accommodated outside the box interior, preserving the standard box volume while providing adequate space for equipment mechanisms inside the box
