Rotatable Wiring Connector Assembly for Cramped Electrical Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wiring management approaches are inefficient and difficult to access in cramped or limited spaces during installation or service of electrical devices, leading to slow wiring connections.
Innovation Solution
A rotatable wiring connector assembly within a wiring box that can be mounted in a fixed or rotatable position, allowing workers to easily access and terminate connections by rotating the assembly for improved usability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fixed wiring connector assembly is used, then the structure is simple and stable, but the accessibility and ease of operation are poor in cramped spaces
Solution Approach 1:
The wiring connector assembly is designed to be rotatable rather than fixed, allowing it to change orientation dynamically. The assembly can rotate about an axis to present different faces for wire access, transforming a static structure into a dynamic one that adapts to installation needs in confined spaces.
Solution Approach 2:
The invention adds rotational freedom to the wiring connector assembly, introducing a new degree of freedom (rotation about an axis) to the otherwise fixed three-dimensional structure. This allows workers to access connectors from different angular positions without requiring additional linear space.
2Productivity
If the wiring connector assembly is made rotatable, then the ease of operation and accessibility are improved, but the device complexity increases
Solution Approach 1:
The rotatable mounting mechanism allows the wiring connector assembly to be positioned in multiple orientations, enabling workers to access connectors from various angles. This dynamic positioning capability directly improves wiring connection efficiency by eliminating the need to contort in cramped spaces or reposition entire fixtures.
3Loss of time
If a fixed position wiring connector is used, then the installation is simple, but the wiring time and effort are excessive due to limited access
Solution Approach 1:
The rotatable assembly allows workers to quickly adjust the orientation of wiring terminals to accessible positions, significantly reducing the time required to make connections in confined spaces compared to fixed installations where workers must work in awkward positions.

AI summary
An electrical device can have an associated wiring box for connecting the electrical device to an external electrical supply, for example to utility power. The wiring box can include an opening suitable for worker access, so that a worker can connect or disconnect the electrical device from electrical power. Wiring connectors can be rotatably mounted in the wiring box for making the electrical connection. The wiring connectors can be rotated to one orientation to enhance worker access through the opening, for example during installation, and to another orientation for long-term operation.
