Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If incineration method is used to treat household refuse, then energy recovery is possible, but safety hazards increase due to high water content and low heat value
Solution Approach 1:
The patent changes the temperature parameter from high-temperature incineration to low-temperature electromagnetic field heating (below 200°C), and changes the energy conversion mechanism from combustion to electromagnetic resonance, thereby recovering energy while avoiding safety hazards associated with traditional incineration of high-moisture refuse
2Ease of manufacture
If landfill method is used to treat household refuse, then disposal is achieved, but land resources are occupied
Solution Approach 1:
The patent replaces the mechanical landfill disposal system with an electromagnetic field-based thermal treatment system that decomposes organic matter in place, converting it to water, carbon dioxide, and mineralized residue, thereby eliminating the need for landfill space while maintaining simple operational procedures
3Productivity
If refuse classification is carried out in remote villages, then treatment efficiency improves, but labor requirements increase due to low knowledge level of villagers
Solution Approach 1:
The patent creates a universal treatment device that accepts mixed household refuse without pre-classification and automatically performs separation and treatment functions through electromagnetic field action, making the system adaptable to remote villages with limited technical knowledge while maintaining high treatment efficiency
Solution Approach 2:
The device enables self-service operation where the electromagnetic field automatically separates and treats different types of refuse based on their physical and chemical properties, eliminating the need for manual classification by villagers and reducing labor requirements while improving treatment efficiency
4Productivity
If long transportation distance is used for refuse, then centralized treatment is possible, but cost increases and environmental pollution occurs
Solution Approach 1:
The patent segments the centralized treatment function into distributed on-site treatment units that can be deployed in remote villages, eliminating the need for long-distance transportation while maintaining effective refuse treatment capability and preventing environmental pollution from transport processes

AI summary
A device for wholly treating urban and rural mixed household refuse at low temperature on site is provided. The device includes a vibration sieving and crushing system, a magnetic separator, conveyor belts, a magnetic pulse mineralization reactor and a tail gas purifying device. By using the device, urban and rural mixed household refuse is continuously fed; the mixed household refuse is sieved by the vibrating sieve according to viscosity, weight and size; nonferrous metal is sieved through a magnetic field; and organic substances are conveyed to the magnetic pulse mineralization mixed household refuse treatment device for terminal treatment. So, efficient reduction and harmlessness of the organic substances in the mixed household refuse are realized, and the pollution of organic wastes on the environment is effectively eliminated.
