Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional housing frames for electrical apparatuses require significant cost and effort to achieve arbitrary dimensions and shapes, and demand high skill levels due to their standardized equal angle steel construction and welding processes, which complicates production and increases operational time.
Innovation Solution
A housing frame composed of beams formed by bending rectangular metal plates, allowing for flexible dimensions and shapes, with connection members that simplify assembly using fastening members rather than welding, thereby reducing production complexity and increasing design flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If equal angle steel is used to constitute the housing frame, then the structural strength is ensured, but the cost and effort increase significantly when arbitrary dimensions and shapes are required
Solution Approach 1:
The patent changes the fundamental parameter of beam formation from standardized equal angle steel to custom-bent metal plates. This allows the beam dimensions, shapes, and configurations to be customized according to specific housing requirements, achieving arbitrary dimensions and shapes without the high costs associated with standardized steel components
Solution Approach 2:
Instead of selecting from pre-standardized equal angle steel components, the patent inverts the approach by creating custom beams through bending metal plates. This reversal of the selection process enables tailored dimensional flexibility while reducing manufacturing costs for non-standard configurations
2Manufacturing precision
If equal angle steel is welded to form the housing frame, then the structural integrity is maintained, but the skill level required for operators increases
Solution Approach 1:
The patent replaces the welding process with a mechanical connection system using connection members that attach beams to each other and to panels. This substitution eliminates the need for skilled welding operations while maintaining structural integrity through standardized mechanical fastening methods
Solution Approach 2:
The patent introduces connection members as intermediary components between beams and panels. These connection members serve as mediators that join structural elements without requiring direct welding, thereby reducing operator skill requirements while preserving dimensional accuracy and structural integrity
3Strength
If welding is used to connect beams, then the joint strength is achieved, but the production time and complexity increase
Solution Approach 1:
The patent replaces the welding process with mechanical connection members that can be quickly assembled and disassembled. This substitution maintains joint strength through robust mechanical fastening while dramatically reducing assembly time and production complexity compared to welding operations

AI summary
A housing frame includes a first and second beams connected to each other through a connection member. The two beams are each obtained by perpendicularly bending a metal plate twice in the longitudinal direction. The second beam is arranged perpendicular to the first beam. The connection member has a connection base portion extending from a bent side surface of a second base portion to a bent side surface of a first base portion through a cut portion formed in a first side portion and overlaps with the first base portion and the second base portion. The connection base portion and the first base portion are fastened together by a first fastening member, and the connection base portion and the second base portion are fastened together by a second fastening member.
