Hook Attachment Structure for Rigid Electric Panel Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hook-based assembly structures for electric apparatuses require elastic deformation, limiting the increase in rigidity and assembly strength, especially when the number of hooks is limited by the shape and size of the members.
Innovation Solution
An electric apparatus design featuring a first member with an attachment hole and a second member with a hook, where the first member's edge portion is elastically deformable to allow hook insertion without requiring elastic deformation of the hook or engaged portion, enhancing the assembly strength by eliminating the need for elastic deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If elastic deformation is used in the hook assembly structure, then the hook can be inserted into the attachment hole, but the rigidity and assembly strength are limited
Solution Approach 1:
The first portion of the first member is designed with different properties from the rest of the structure - it is made elastically deformable while other parts maintain high rigidity. This localized elasticity allows insertion while preserving overall assembly strength, resolving the contradiction between ease of insertion and assembly strength.
2Strength
If the number of hooks is increased to improve assembly strength, then the assembly strength can be enhanced, but the shape and size constraints of external appearance members limit the number of hooks
Solution Approach 1:
The invention changes the key parameter from the number of hooks to the rigidity of the hook and engaged portion. By making the hook structure highly rigid and eliminating the need for elastic deformation during assembly, each hook can provide maximum strength, compensating for the limited number of hooks that can be accommodated due to shape constraints.
3Strength
If the rigidity of the hook is increased to improve assembly strength, then the assembly strength improves, but elastic deformation becomes difficult and insertion becomes problematic
Solution Approach 1:
The first portion of the first member is specifically designed with elastically deformable properties, while the hook and engaged portion maintain high rigidity. This local elasticity provides the necessary insertion capability without compromising the rigidity of the hook, resolving the contradiction between hook rigidity and ease of insertion.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design increases the assembly strength of the members by reducing the necessity for elastic deformation, allowing for improved rigidity and a more stable connection without compromising the size or shape constraints.
Implementation Method 1
the first portion is elastically deformable such that it swells in the first direction to allow insertion of the hook into the attachment hole

AI summary
A support arm has an attachment hole formed thereon. The support arm has a first side wall and a second side wall both constituting edge of the attachment hole. An engaged convex portion is formed on the second side wall. The first side wall restricts a hook of the front panel from moving in a direction away from the second side wall toward the first wall. The first side wall is elastically deformable such that it swells in the direction.
