Metal-Resin Composite Structure With One-Sided Resin Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing metal-resin composites face challenges in achieving high joint strength and rigidity while maintaining a simple structure, as the thickness of the metal plate decreases due to cross-sectional restrictions and the complexity of resin material distribution on both surfaces complicates handling and versatility.
Innovation Solution
A metal-resin composite design featuring cut-and-raised portions with cutout holes and raised pieces on one surface, integrated with a resin material, which secures high joint strength by burying the cut-and-raised portions in the resin, reducing resin layers to one side, and using burring to form tapered shapes for enhanced adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If resin material is disposed on both surface sides of the metal plate, then joint strength is improved, but structure becomes complicated and handling becomes difficult
Solution Approach 1:
The invention extracts the resin material from one surface side of the metal plate, disposing it only on the other surface side. This reduces the structure from two resin layers to one, simplifying the overall structure while maintaining joint strength through the cut-and-raised portion design that ensures adequate resin-metal contact area.
2Strength
If resin material is disposed on both surface sides of the metal plate, then joint strength is improved, but handling becomes difficult and versatility is lacking
Solution Approach 1:
By removing the resin material from one surface side and disposing it only on the other surface side, the invention simplifies handling operations. The reduced structure allows for easier manipulation, assembly, and integration with other members, thereby improving versatility without compromising joint strength.
3Volume of moving object
If metal plate thickness is reduced for cross-sectional restriction, then compactness is improved, but rigidity decreases
Solution Approach 1:
The invention creates a composite structure by integrating the metal plate with the resin material through the cut-and-raised portion. This composite design allows for reduced metal plate thickness while maintaining overall rigidity, as the resin material compensates for the reduced metal thickness by providing additional structural support and forming an integrated rigid assembly.
