Resin Frame Metal Plate Rigidity Airflow Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic apparatus frame, primarily made of resin, lacks sufficient rigidity, which is a challenge for downsizing while maintaining structural integrity.
Innovation Solution
Incorporating a metal plate attached to the resin frame, specifically to the outer periphery, enhances the rigidity without increasing the frame's thickness, and functions as a wall to define air flow paths, reducing the number of parts and height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the frame is entirely formed from resin, then the manufacturing ease is improved, but the rigidity of the frame deteriorates
Solution Approach 1:
The frame is constructed by combining resin and metal materials. The resin frame provides ease of manufacture and molding, while metal plates are attached to specific portions to enhance rigidity. This composite structure resolves the contradiction by leveraging the advantages of both materials without requiring the entire frame to be made from rigid metal.
2Strength
If the thickness or size of the frame is increased to enhance rigidity, then the rigidity is improved, but the downsizing objective deteriorates
Solution Approach 1:
Instead of uniformly increasing the frame's thickness or size, metal plates are strategically attached to specific portions of the resin frame where rigidity enhancement is most needed. This localized reinforcement approach improves structural strength without proportionally increasing the overall frame volume, thereby supporting the downsizing objective.
3Strength
If additional components are added to enhance rigidity, then the rigidity is improved, but the device complexity increases
Solution Approach 1:
The metal plates attached to the frame serve multiple functions: they enhance rigidity, define air flow paths, and act as structural supports. By integrating these multi-functional elements into the frame design, the invention improves rigidity without proportionally increasing device complexity, as the same components perform multiple roles.
