Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If metal grate channels are used to suppress microwave energy, then microwave leakage is reduced, but material flow becomes blocked or slowed
Solution Approach 1:
The patent employs movable flaps instead of fixed metal grates. These flaps can dynamically adjust their position to balance microwave suppression and material flow requirements, resolving the contradiction between blocking microwaves and allowing material passage
Solution Approach 2:
The patent uses flexible mesh flaps that can conform to the tunnel structure while maintaining microwave suppression effectiveness. These flexible elements can adapt to material flow conditions while continuing to block microwave energy leakage
2Object-affected harmful factors
If water jackets or reflectors are used to suppress microwave energy, then microwave leakage is prevented, but system flexibility and portability are reduced
Solution Approach 1:
The patent divides the suppression system into modular tunnel sections with discrete flap assemblies. This segmentation allows the system to be configured in different sizes and arrangements, improving portability and adaptability while maintaining effective microwave suppression at each access opening
Solution Approach 2:
The patent employs mesh flaps with adjustable parameters such as mesh density, flap size, and tunnel dimensions that can be optimized for different deployment scenarios. This allows the same basic design to adapt to various portability requirements without sacrificing microwave suppression effectiveness
3Object-affected harmful factors
If square channel grates are used for material introduction, then microwave suppression is achieved, but granular material flow is blocked
Solution Approach 1:
The movable flaps can open to accommodate granular material introduction while closing to suppress microwaves. This dynamic behavior eliminates the blockage problem of fixed square channels while maintaining microwave suppression when needed
Solution Approach 2:
The flexible mesh flaps allow granular materials to pass through more easily compared to rigid square channels, while still maintaining effective microwave suppression. The flexibility of the mesh structure accommodates material flow without creating blockages
