Torsional Mounting Structure for Secure Panel Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting structures for components face issues with wobbling and potential breaking due to compression stress when temporarily fixed to a mounting target, as they rely on deflection and locking mechanisms that are not robust enough to withstand stress.
Innovation Solution
A mounting structure featuring a main body with an elastic portion and a temporary fixing unit that includes a supporting portion with a distal end, a holding portion with an inclined surface, and a spring portion, which undergoes torsional deformation to prevent stress on the holding portion and enhance adhesion through elastic deformation, ensuring secure temporary fixation without wobbling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the locking element is pushed further into the pass-through opening to improve fixation strength, then the temporary fixation becomes stronger, but the connection portion of the locking element and pin structure may break due to compression stress
Solution Approach 1:
The patent changes the deformation mode from compression to torsion. The spring portion is designed to undergo torsional deformation instead of compression, fundamentally changing the stress parameter and avoiding the breaking issue while maintaining fixation strength
Solution Approach 2:
The temporary fixing unit is segmented into distinct functional portions: supporting portion, spring portion, and holding portion. This segmentation allows each part to perform its specific function - the spring portion handles deformation while the holding portion provides fixation, preventing stress concentration at connection points
2Ease of operation
If the pin structure is used to temporarily fix the component-member supporting body, then the mounting structure can be temporarily fixed to the mounting wall, but the component-member supporting body cannot help wobbling with respect to the mounting wall
Solution Approach 1:
The patent introduces a dynamic elastic portion that can deform to adapt to the mounting target surface. This dynamic characteristic allows the elastic portion to conform to surface irregularities, providing stable contact and preventing wobbling while maintaining ease of installation
Solution Approach 2:
The elastic portion acts as an intermediary between the temporary fixing unit and the mounting target. It mediates the contact by deforming to match the surface geometry, ensuring stable fixation without wobbling while keeping the installation process simple
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents breaking of the temporary fixing unit and enhances adhesion to the mounting target, ensuring the component remains securely attached without wobbling, by distributing stress through torsional deformation and elastic deformation.
Implementation Method 1
a spring portion connecting the distal end portion of the supporting portion and the holding portion and undergoing torsional deformation when the holding portion is pushed down while the inclined surface of the holding portion slides along the edge portion of the aperture
Implementation Method 2
the elastic portion is forced to undergo elastic deformation while pressing against the mounting target

AI summary
A temporary fixing unit includes a supporting portion including a distal end portion passed through an aperture, and a holding portion provided with an inclined surface that slides along an edge portion of the aperture when passed through the aperture. The temporary fixing unit also includes a spring portion connecting the distal end portion of the supporting portion and the holding portion and that deforms in a twisted manner as the holding portion is pushed down when the inclined surface of the holding portion slides along the edge portion of the aperture. When the holding portion is passed through the aperture, a portion of a door panel is held between the holding portion and an elastic portion. Furthermore, the elastic portion is elastically deformed so as to press the door panel.
