Resin Molded Body Extension Part Protects Mounting Target
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Resin molded bodies with exposed metal attachment members pose challenges in fixing them to mounting targets, such as vehicle bodies, as they can damage the target and complicate the fixing process, reducing working efficiency.
Innovation Solution
Incorporating an extension part made of resin that protrudes further than the metal attachment member, allowing it to contact and deform away from the mounting target, thus avoiding interference and damage, and ensuring efficient fixation without special considerations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal attachment member is exposed or protruded from the surface of the resin molded body, then the fixation strength to the mounting target is improved, but the risk of damaging the mounting target increases and the fixing process becomes more complex
Solution Approach 1:
The patent introduces a resin extension part as an intermediary element between the metal attachment member and the mounting target. This extension part protrudes further than the metal member and makes contact with the mounting target first, serving as a protective mediator that prevents direct contact between the metal member and the target surface, thereby eliminating the risk of damage while maintaining fixation strength.
2Strength
If a metal attachment member is exposed or protruded from the surface of the resin molded body, then the fixation strength to the mounting target is improved, but the working efficiency of the fixing process deteriorates
Solution Approach 1:
The resin extension part performs a preliminary protective action by contacting the mounting target first during the fixing process. This preliminary contact guides the positioning and prevents damage before the metal attachment member makes contact, streamlining the fixing process and improving working efficiency without requiring additional protective measures or special handling procedures.
3Strength
If a metal attachment member is exposed or protruded from the surface of the resin molded body, then the fixation strength to the mounting target is improved, but the complexity of the fixing process increases
Solution Approach 1:
The patent merges the protective function and the guiding function into a single resin extension part structure. This unified design eliminates the need for separate protective covers or alignment aids, simplifying the overall fixing process while maintaining strong fixation through the metal attachment member.
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 resin extension part enhances working efficiency by reducing the risk of damage to the mounting target and preventing interference with the fixation process, allowing for smoother and more efficient attachment of resin molded bodies, even when metal attachment members are exposed.
Implementation Method 1
the at least one part being configured to allow deforming in a direction away from the mounting target upon the resin molded body being fixed to the mounting target

AI summary
A resin molded body (10) includes a metal attachment member (22) and an extension part (33, 34) extending from the resin molded body. At least one part of the metal attachment member (22) is exposed in a mounting surface (20a) of the resin molded body. The mounting surface (20a) is to be facing to the mounting target when the resin molded body is fixed to a mounting target. At least one part of the extension part (33, 34) is protruded outside the mounting surface. A protrusion length of the at least one part of the extension part (33, 34) from the mounting surface is larger than a protrusion length of the metal attachment member (22) from the mounting surface. The at least one part is configured to allow deforming in a direction away from the mounting target when the resin molded body is fixed to the mounting target.
