Solution Overview
Problem
Conventional food waste disposal systems face inefficiencies in processing time, generation of noxious gases and odors, inconvenient operation, and excessive water usage, as well as the inability to handle packaging waste and hard materials, leading to degraded processing efficiency and environmental impact.
Innovation Solution
A food waste separating apparatus that sorts input garbage into decomposable food waste and impurity garbage using a crushing unit, filtering chamber with perforation members, and a sweeper device, coupled with a BOD reducing apparatus to purify wastewater, reducing water consumption and improving operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional decomposition methods using microorganisms are used, then organic waste can be disposed of, but processing time is excessively long and processing efficiency is low
Solution Approach 1:
The patent applies preliminary action by pre-crushing the organic waste before decomposition to increase surface area, and pre-heating the air before introducing it to the decomposition chamber. These preliminary treatments prepare the waste and environment for more efficient decomposition, reducing the overall processing time while maintaining effective organic waste disposal.
2Productivity
If conventional decomposition apparatuses are used, then organic waste can be processed, but noxious gases and offensive odors are generated due to incomplete decomposition
Solution Approach 1:
The patent uses heated air (a form of accelerated oxidation) to enhance the decomposition process. By providing thermal energy and oxygen through pre-heated air, the decomposition occurs more completely and rapidly, preventing the generation of noxious gases and offensive odors that result from incomplete decomposition in conventional systems.
Solution Approach 2:
The patent implements continuous agitation of the organic waste during decomposition through rotating blades. This continuous mechanical action ensures uniform heating and oxygen distribution throughout the waste mass, maintaining consistent decomposition conditions and preventing localized incomplete decomposition that would generate harmful gases and odors.
3Ease of operation
If manual operation with analogue switches is used, then the apparatus can be operated, but manipulation is inconvenient and operation mode selection is impossible
Solution Approach 1:
The patent replaces the mechanical analogue switch system with an electronic control system featuring push-button switches and digital display. This substitution eliminates the inconvenience of manual manipulation while providing clear operation mode selection and status indication, improving ease of operation without significantly increasing perceived device complexity.
4Productivity
If the shell case cannot be washed, then the structure remains simple, but offensive odor is generated and disposal efficiency degrades
Solution Approach 1:
The patent implements a self-cleaning function where water is automatically supplied to wash the interior walls of the shell case after the decomposition cycle completes. This self-service cleaning mechanism maintains disposal efficiency and prevents offensive odors without requiring manual intervention, effectively addressing the issue of waste residue accumulation while keeping the operation simple for the user.
