Engineering Contradiction Analysis
1Ease of manufacture
If the case is formed by bending a metal sheet, then the case can be manufactured with simple structure, but gaps are generated at joints causing electromagnetic noise leakage
Solution Approach 1:
The case is divided into multiple separate metal sheet components that are joined together through bending and joining processes, allowing for modular manufacturing while maintaining electromagnetic shielding effectiveness through proper joining techniques
Solution Approach 2:
Electromagnetic shielding material or conductive sealing elements are introduced as intermediary components at the joints of the metal sheet case to bridge gaps and prevent electromagnetic noise leakage while maintaining the bent sheet structure
2Device complexity
If the case is formed by bending a metal sheet, then manufacturing process is simple, but electromagnetic noise cannot be sufficiently reduced
Solution Approach 1:
Thin conductive shielding films or flexible electromagnetic shielding materials are applied to the inner surfaces of the bent metal sheet case, conforming to the complex geometry while providing continuous electromagnetic shielding without requiring complex structural modifications
Solution Approach 2:
The surface properties of the metal sheet case are modified through coating or treatment to enhance electromagnetic shielding capabilities, changing the electrical conductivity or magnetic properties of the case surface to improve noise reduction effectiveness
