Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple smashing processor is used for kitchen waste, then the device complexity is reduced, but the treatment effectiveness and resource utilization capability deteriorate
Solution Approach 1:
The treatment device is divided into multiple functional modules: smashing module, filtration module, drying module, and resource utilization module. Each module performs a specific function in the waste treatment process, allowing the system to achieve comprehensive treatment effectiveness while maintaining manageable device complexity through modular design.
Solution Approach 2:
Multiple treatment functions (smashing, filtration, drying, and resource recovery) are combined into a single integrated device. The device processes kitchen waste through multiple stages within one system, simultaneously achieving waste reduction and resource utilization, thereby improving overall treatment effectiveness without requiring separate devices for each function.
2Loss of time
If kitchen waste is not treated timely, then the loss of time for waste accumulation increases, but environmental pollution and health hazards worsen
Solution Approach 1:
The device performs preliminary treatment of kitchen waste immediately upon generation by capturing waste at the source through the smashing and filtration modules. This preliminary action prevents waste accumulation and subsequent environmental pollution by processing waste in real-time before it can cause harm.
Solution Approach 2:
The treatment device operates continuously to process kitchen waste as it is generated, maintaining an ongoing treatment process rather than batch processing. The continuous operation ensures waste is treated promptly, minimizing accumulation time and preventing environmental pollution and health hazards associated with stored waste.
3Device complexity
If simple smashing is performed without further treatment, then the device complexity is reduced, but the resource utilization capability and waste reduction effectiveness deteriorate
Solution Approach 1:
The device separates waste into different components through filtration and drying modules, recovering usable resources such as dried organic matter for composting or energy generation. This recovery process reduces the volume of waste that needs to be discarded, achieving significant waste reduction while maintaining reasonable device complexity through systematic separation and recovery mechanisms.

AI summary
The embodiments of the present disclosure provide a centralized treatment device for kitchen waste. The centralized treatment device includes an upper box, an outer cover, a pulverizer, an inner cover, a filter press, a drying granulator, a lower box, an electrolysis device, a hanging basket, a material box, an exhaust fan, and a linkage mechanism. Smashed kitchen waste is subjected to solid-liquid separation by the filter press. Filter residues enter the drying granulator to be partially carbonized, and partially carbonized filter residues and mixed powder treatment agent form solid residue particles. The solid residue particles degrade and adsorb pollutants in the water after being activated by an acidic solution. Meanwhile, accumulated water-absorbing solid residue particles help to degrade the pollutants in the water through the electrolysis device. A separation area is configured to separate oil and discharge the oil separately.
