Solution Overview

Problem

Existing composting devices face issues with material clumping and blockages in the composting chamber, leading to malfunctions and reduced operational reliability.

Innovation Solution

A composting device with a conveying unit that operates in two modes: conveying organic material to subsequent chambers and mixing it within the initial chamber, using a control device to manage the direction of rotation and prevent blockages, and incorporating heating, ventilation, and humidification for optimal composting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the bottom of the composting chamber is opened to remove compost material, then the composted material can be collected, but material blockages can occur at the opening and cause system malfunction

Engineering Contradiction:
Improvecompost material removalVSAvoidsystem operational reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The composting chamber is divided into multiple sections with intermediate discharge openings, allowing分段 removal of compost material and preventing complete blockage of the main outlet

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A conveying unit with conveying elements acts as an intermediary mechanism between the composting chamber and collection container, transporting material through controlled pathways that prevent direct contact and potential blockages at chamber openings

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If organic material is placed in the composting chamber, then composting can proceed, but material can clump together causing blockages

Engineering Contradiction:
Improvecomposting processVSAvoidmaterial flow reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The conveying unit operates in two modes with reversible rotation direction - conveying mode for material transport and mixing mode for preventing clumping, dynamically switching between functions to maintain reliable operation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The conveying unit periodically alternates between conveying and mixing operations, creating cyclic action that prevents material from settling and clumping during the composting process

Inventive Principle:
Principle #19Periodic action

3Device complexity

If a conveying unit with single rotation direction is used, then material transport is simple, but material blockages occur and operational reliability decreases

Engineering Contradiction:
Improveconveying unit structureVSAvoidoperational reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The conveying unit incorporates reversible rotation capability, allowing it to switch between conveying mode (one direction) and mixing mode (opposite direction), adding dynamic functionality that prevents blockages while maintaining relatively simple structure

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The same conveying unit performs multiple functions - both material conveying and material mixing - eliminating the need for separate mechanisms and maintaining structural simplicity while improving reliability

Inventive Principle:
Principle #6Universality (Multi-functionality)
