Solution Overview

Problem

Current refuse chutes handle a single waste stream, leading to environmental impact due to difficulty in separating materials for recycling, and existing separation methods like rotatable turrets are prone to damage from refuse impact.

Innovation Solution

A separator assembly with a set of vertically aligned chutes and a positioning mechanism that aligns each chute with a refuse chute outlet to direct waste to specific receptacles, reducing maintenance and enabling straightforward separation of different waste types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a rotatable turret or moveable deflector plate is used to separate refuse, then waste can be directed to different receptacles, but the turret/deflector is regularly damaged by heavy waste impact and requires frequent maintenance

Engineering Contradiction:
Improvewaste separation capabilityVSAvoiddevice durability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system divides the waste stream into multiple separate chutes, each handling a specific category of waste. Instead of one large moveable component, multiple fixed chutes are positioned to receive different types of refuse, eliminating the need for a single large turret while achieving the same separation function.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of moving a large turret to redirect waste, the invention inverts the approach by keeping chutes fixed and moving only the smaller inlet gates that control waste flow into each chute. This reverses the traditional mechanism, reducing the size and vulnerability of moveable parts.

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

2Device complexity

If a single outlet refuse chute is used, then the system is simple, but waste cannot be separated into different categories and most waste ends up in landfill

Engineering Contradiction:
Improvechute system simplicityVSAvoidwaste categorization capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The single outlet is segmented into multiple outlets, each leading to a separate chute for different waste categories. This segmentation allows waste separation while maintaining relative system simplicity by using a modular approach where each chute is a straightforward vertical channel.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a single vertical dimension to multiple vertical dimensions by positioning several chutes side-by-side. Each chute handles a different waste category, effectively adding spatial separation in the horizontal plane while maintaining vertical waste flow paths.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If manual sorting of waste is performed after collection, then recyclability is reduced, but the system requires only a single outlet chute

Engineering Contradiction:
Improvesystem construction simplicityVSAvoidrecyclable material recovery
Core Design Contradiction:
Ease of manufactureVSLoss of substance

Solution Approach 1:

The system performs waste separation at the source, before waste is collected and transported. By separating waste into different categories at the point of disposal, the system eliminates the need for later manual sorting and ensures recyclable materials are properly directed from the beginning.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention replaces manual sorting operations with an automated mechanical separation system. The inlet gates and chute positioning mechanism automatically direct different waste types to appropriate receptacles, substituting human labor with a automated mechanical system that improves both efficiency and material recovery.

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

AI summary

There is described a separator assembly (100, 200, 300, 400) for a refuse chute (10). The separator assembly (100, 200, 300, 400) comprises a set of separating chutes (110, 120, 130), each comprising an inlet (112, 122, 132) for receiving refuse and an outlet (114, 124, 134) for outputting refuse. The assembly (100, 200, 300, 400) also comprises a positioning mechanism (140) configured to locate the set of separating chutes (110, 120, 130) relative to the refuse chute (10) to align an inlet (112) from one of the set of separating chutes (110) with an outlet (12) of the refuse chute (10). Suitably, each of the set of separating chutes (110, 120, 130) are arranged to direct refuse to a different location when the corresponding inlet (112, 122, 132) is aligned with the outlet (12) of the refuse chute (10). There is also described a separator system (1000) comprising the aforementioned assembly (100, 200, 300, 400).
