Solution Overview
Problem
Mobile terminals face challenges in achieving both waterproof and heat radiation functions while maintaining an aesthetically pleasing design, particularly when the outer and inner cases are independently fabricated and coupled, as metal materials have diverse properties that complicate integral formation and require additional processing costs.
Innovation Solution
A mobile terminal design featuring a metal plate with high heat conductivity and a middle case made of SUS or STS, where a molding unit is used to couple these components, providing a waterproof and heat radiation-enhanced structure with curved surfaces for improved grip and aesthetics, and differing materials are used for unique characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the outer case and inner plate are independently fabricated and coupled, then manufacturing flexibility and material selection are improved, but waterproof performance and heat radiation performance deteriorate
Solution Approach 1:
A molding unit is introduced as an intermediary component between the outer case and inner plate. This molding unit fills the gap formed by the coupling structure and provides waterproof sealing, thereby maintaining manufacturing flexibility while ensuring waterproof performance through the mediating sealing function.
Solution Approach 2:
The patent employs different materials for the outer case (metal plate with high heat conductivity) and inner plate (SUS or STS), creating a composite structure. This allows each component to be optimized for its specific function while the molding unit bridges the materials to ensure both waterproofing and heat radiation performance.
2Ease of manufacture
If the outer case and inner plate are independently fabricated and coupled, then manufacturing flexibility and material selection are improved, but heat radiation performance deteriorates
Solution Approach 1:
The outer case is made of metal plate with high heat conductivity while the inner plate uses SUS or STS, creating a composite thermal management structure. The molding unit connects these materials to enable effective heat transfer from internal components through the metal outer case, maintaining heat radiation performance despite independent fabrication.
Solution Approach 2:
The molding unit acts as a thermal bridge between the inner plate and outer case, ensuring continuous heat conduction path while allowing independent fabrication of components. This mediator maintains thermal performance without compromising manufacturing flexibility.
3Temperature
If metal materials are used for outer case and inner plate, then heat conductivity and aesthetics are improved, but processing complexity and cost increase
Solution Approach 1:
The metal structure is segmented into separate components (outer case, inner plate, molding unit) that can be manufactured independently using different processes. This segmentation reduces processing complexity for each component while maintaining the overall heat conductivity benefits of metal materials.
Solution Approach 2:
The patent uses a composite structure combining metal plate for the outer case with SUS/STS for the inner plate and a molding unit material, allowing each component to be processed with appropriate methods for its material properties, thereby reducing overall processing complexity while maintaining heat conductivity.
