Solution Overview

Problem

Existing kitchen garbage treatment devices require a power source to dry kitchen garbage, which limits their use without access to electricity.

Innovation Solution

A kitchen garbage treatment material composed of water-absorbent powders or grains made from fluff pulp and water-absorbent polymer obtained from sanitary products, which absorb moisture from kitchen garbage, eliminating the need for a power source.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a heater is used to dry kitchen garbage, then moisture removal effectiveness is improved, but dependency on power source increases

Engineering Contradiction:

Improvemoisture removal effectivenessVSAvoid usability without power source

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent replaces the mechanical heating system with a chemical absorption system. Water-absorbent materials (such as calcium oxide, calcium hydroxide, or molecular sieves) are placed in the storage container to chemically absorb moisture from kitchen garbage, eliminating the need for electrical heaters and enabling operation without power sources while maintaining moisture removal effectiveness

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the operational parameter from active heating (requiring power) to passive chemical absorption (no power needed). By selecting appropriate water-absorbent materials with different absorption capacities and characteristics, the system achieves effective moisture removal without electrical power, thereby improving adaptability to various usage environments

Inventive Principle:

Principle #35Parameter changes

2Productivity

If a heater for drying is used, then moisture removal capability is improved, but device complexity increases

Engineering Contradiction:

Improvemoisture removal capabilityVSAvoid device structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent simplifies the device structure by replacing the complex heating system (power source, heater, control circuitry) with a simple chemical absorption system. The water-absorbent material is directly placed in the storage container, eliminating multiple components and reducing device complexity while maintaining moisture removal capability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts the moisture removal function from the heating system and implements it through a separate, simpler chemical absorption mechanism. This separation allows the core function to be achieved without the complex heating infrastructure, reducing overall device complexity

Inventive Principle:

Principle #2Taking out (Extraction)
