Solution Overview

Problem

The collection and disposal of kitchen waste pose challenges due to vermin attraction, odor issues, and health hazards, as existing methods require frequent collection and lack effective on-site processing solutions for domestic and commercial kitchens.

Innovation Solution

An apparatus that processes kitchen waste into a stable, dry, and rot-resistant granular form by comminuting, dewatering, compressing, and mixing with a cementitious powder to inhibit bacterial growth, allowing for on-site treatment and reduced collection frequency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If kitchen waste is stored for collection, then collection frequency can be reduced, but vermin attraction and odor problems worsen

Engineering Contradiction:
Improvecollection frequencyVSAvoidvermin attraction and odor
Core Design Contradiction:
Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The apparatus performs preliminary processing of kitchen waste by comminuting, dewatering, compressing, and mixing with cementitious powder before final disposal. This preliminary action stabilizes the waste, preventing vermin attraction and odor generation, thereby allowing for reduced collection frequency while eliminating the harmful effects associated with stored waste.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The apparatus changes the physical and chemical parameters of kitchen waste through comminution (reducing particle size), dewatering (removing moisture), compression (increasing density), and mixing with cementitious powder (altering chemical composition). These parameter changes transform the waste into a stable, non-attractive form that does not generate odors or attract vermin.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If on-site processing is implemented, then vermin attraction and odor issues are reduced, but device complexity increases

Engineering Contradiction:
Improvevermin attraction and odorVSAvoidprocessing apparatus complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The processing apparatus is segmented into distinct functional modules: comminution device, dewatering device, compression device, and mixing device. Each module performs a specific function in the waste treatment process, making the overall system more manageable and easier to implement while effectively reducing vermin attraction and odor problems through comprehensive processing.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If waste is processed into granular form, then storage stability improves, but processing time and energy consumption increase

Engineering Contradiction:
Improvewaste storage stabilityVSAvoidprocessing energy consumption
Core Design Contradiction:
Stability of the object's compositionVSUse of energy by moving object

Solution Approach 1:

The apparatus applies parameter changes through controlled compression and mixing with cementitious powder to transform waste into stable granular form. The compression process densifies the waste while the cementitious powder chemically stabilizes it, creating a product that maintains its composition during storage. This approach achieves stability while managing energy consumption through efficient processing parameters.

Inventive Principle:
Principle #35Parameter changes

AI summary

A method of processing waste, such as food waste, from a kitchen is described in which apparatus on the premises of the kitchen receives the waste, comminutes the received waste to provide comminuted waste, dewaters the comminuted waste to provide dewatered waste, compresses the dewatered waste to produce compressed waste; and provides processed waste to await collection.
