Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional composite housing with electromagnetic wave shielding is used, then the housing structure is simple and manufacturing is easy, but electromagnetic waves can enter through gaps between components and affect electronic components
Solution Approach 1:
The shielding portion is nested within the housing structure, positioned between the radiator and the housing interior. This nested configuration allows the shielding function to be integrated into the existing housing without requiring a completely redesigned structure, thereby blocking electromagnetic waves from entering through gaps while maintaining structural simplicity.
Solution Approach 2:
The shielding portion acts as an intermediary element between the radiator and the housing interior. This intermediate shielding structure blocks electromagnetic waves generated by the radiator or entering from outside, preventing them from affecting electronic components while allowing the housing to maintain its original simple design.
2Object-affected harmful factors
If the housing is designed to cover the outer periphery of electronic components, then structural protection is provided, but gaps between components allow electromagnetic waves to penetrate and affect electronics
Solution Approach 1:
Instead of requiring the entire housing to provide uniform electromagnetic shielding, the shielding portion is strategically placed in the specific local region where electromagnetic waves can penetrate through gaps between components. This localized shielding approach provides effective protection against electromagnetic wave penetration while maintaining the overall structural integrity and simplicity of the housing.
3Object-affected harmful factors
If a shielding portion is added to block electromagnetic waves, then electromagnetic shielding effectiveness is improved, but the device becomes more complex and larger
Solution Approach 1:
The shielding portion is merged with the existing housing and radiator structures. By integrating the shielding function into the existing components rather than adding a separate standalone shielding system, the overall device volume is minimized while still achieving effective electromagnetic wave blocking between the radiator and electronic components.
