Folded Electrical Junction Box Manufacturing with Rounded Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional metal electrical junction boxes, whether made by welded or die-stamped techniques, pose safety concerns due to sharp corners and edges, and the die-stamping process is time and cost-intensive.
Innovation Solution
A method and system for manufacturing folded electrical junction boxes from a single sheet of metal, involving operations like forming extruded threaded holes, cutting walls, scoring, and folding to create rounded edges and corners, which are then secured using locking devices, allowing for the production of safe and durable boxes in a single manufacturing operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welded construction techniques are used to make metal electrical junction boxes, then structural strength and integrity are improved, but sharp corners and edges are created posing safety concerns
Solution Approach 1:
The patent applies curvature by forming rounded corners and edges on the electrical junction box through a die stamping process. The single piece of metal is shaped with curved transitions at corners and edges, eliminating sharp geometric features while maintaining structural integrity. This directly addresses the safety concern by removing harmful sharp edges that would otherwise be present in welded construction.
2Object-affected harmful factors
If drawing and/or die stamping techniques are used to make metal electrical junction boxes, then rounded corners and edges are achieved improving safety, but manufacturing time and costs increase
Solution Approach 1:
The patent segments the manufacturing process into a single integrated die stamping operation that forms the entire junction box from one piece of metal. This segmentation eliminates multiple steps (such as welding separate pieces) and consolidates the formation of rounded corners, edges, and box structure into one efficient process, reducing overall manufacturing time while maintaining safety features.
Solution Approach 2:
The patent merges multiple manufacturing operations into a single die stamping process. The forming of the box structure, the creation of rounded corners and edges, and the shaping of the single piece of metal are all combined into one continuous operation, improving productivity while preserving the safety benefits of rounded features.
3Object-affected harmful factors
If drawing and/or die stamping techniques are used to make metal electrical junction boxes, then rounded corners and edges are achieved improving safety, but manufacturing costs increase
Solution Approach 1:
The patent segments the metal into a single optimized piece that is formed in one stamping operation. This eliminates the need for multiple components requiring welding or assembly, reducing material waste and manufacturing complexity. The single-piece construction with integrated rounded features achieves safety goals while controlling costs through process simplification.
