Solution Overview

Problem

Current waste treatment methods are inefficient in handling heterogeneous mixtures of household and economic waste, particularly due to the need for prior sorting, which often results in significant portions being incinerated or buried, rather than being recycled or composted, leading to environmental pollution and high costs.

Innovation Solution

A process involving a sorting machine that separates waste into fractions less than 180 mm and a composting installation to treat biodegradable waste, while non-biodegradable recyclable waste is sorted and recycled, allowing for the recovery of a large portion of the waste mixture in an automated and cost-effective manner.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If households perform pre-sorting of waste, then the quantity of waste requiring industrial sorting is reduced, but the reliability of sorting is insufficient and additional infrastructure is required

Engineering Contradiction:
Improvetime for industrial sortingVSAvoidsorting reliability
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

Instead of having households sort waste into separate categories, the invention inverts the approach by collecting all waste together and using automated industrial sorting with optical sensors and AI to identify and separate recyclable materials. This reverses the traditional hierarchy from manual pre-sorting to automated post-collection sorting, achieving both time efficiency and high reliability.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The invention replaces manual mechanical sorting by households with automated optical sensing systems and AI-based identification. The system uses cameras, light sensors, and machine learning algorithms to automatically detect and sort different waste types, eliminating the need for manual pre-sorting infrastructure while achieving superior sorting accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If complex waste is incinerated or buried, then the treatment process is simple, but environmental pollution increases

Engineering Contradiction:
Improvetreatment process complexityVSAvoidenvironmental pollution
Core Design Contradiction:
Device complexityVSObject-generated harmful factors

Solution Approach 1:

The invention extracts recyclable materials from the waste stream using automated sorting systems before the remaining waste is treated. By separating recyclables early in the process, the system enables appropriate treatment for different waste types - recycling for valuable materials and controlled incineration or landfill for residual waste, thereby reducing environmental pollution while maintaining manageable process complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the parameter of waste composition by selectively removing recyclable materials through automated sorting. This parameter change allows the remaining waste stream to be more suitable for environmentally friendly treatment methods, reducing harmful emissions and pollution while keeping the overall treatment process complexity acceptable through modular system design.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If selective collection infrastructure is organized, then waste sorting capability is improved, but costs and traffic generation increase

Engineering Contradiction:
Improvewaste sorting capabilityVSAvoidcosts and traffic
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The invention merges all waste collection into a single stream that is then sorted automatically at the processing facility. This eliminates the need for multiple separate collection infrastructures for different waste types, reducing the number of collection vehicles and associated traffic while maintaining excellent sorting capability through centralized automated processing.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The automated sorting system performs the sorting function automatically without requiring household participation or manual sorting infrastructure. The system uses self-contained optical sensors, AI algorithms, and robotic mechanisms to identify and separate waste types, achieving high sorting capability while eliminating the need for costly multi-bin infrastructure and reducing collection traffic.

Inventive Principle:
Principle #25Self-service
