Solution Overview

Problem

Existing waste compression systems face challenges when compacting waste containing voluminous materials like paper or plastic packaging, which occupy excessive space in collection containers, leading to inefficiencies in waste collection and logistics.

Innovation Solution

A waste compression system equipped with a primary press mechanism that can be maneuvered into two positions - a closing position to compact voluminous waste and a freeing position to allow waste to enter the collection container, utilizing a pendulum device to move waste from the compactor to the container while the primary press either presses against or folds away to accommodate the waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If waste containing voluminous materials like paper or plastic packaging is compacted using existing compression systems, then the waste occupies less space, but the collection container cannot be filled to its full capacity due to the materials being compressed too early

Engineering Contradiction:
Improvespace occupied by wasteVSAvoidfilling degree of collection container
Core Design Contradiction:
Volume of moving objectVSProductivity

Solution Approach 1:

The primary press is designed to be movable between two positions: a closing position for compacting voluminous waste materials, and an open position that allows the compacting aperture to remain clear for receiving waste. This dynamic positioning enables the system to adapt its compaction function based on the waste material being processed, thereby maximizing the collection container's filling degree while still achieving effective compaction when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs preliminary compaction of voluminous waste materials at the compactor before transferring them to the collection container. By compacting these materials in advance, the system reduces their volume before they enter the collection container, allowing more waste to be stored while maintaining optimal space utilization.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If a fixed compaction system is used, then the structure is simple, but it cannot adapt to different types of waste materials requiring different compaction levels

Engineering Contradiction:
Improvestructure of compression systemVSAvoidadaptability to different waste materials
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The primary press is designed to be movable between two positions: a closing position for compacting voluminous waste materials, and an open position that allows the compacting aperture to remain clear for receiving waste. This dynamic positioning enables the system to adapt its compaction function based on the waste material being processed, thereby maximizing the collection container's filling degree while still achieving effective compaction when needed.

AI summary

The present invention pertains to a device and a method for waste compression for use especially in a compactor (5) arranged at a collection container (4) for waste. This compactor (5) features a compacting compartment (6) with a loading aperture (7) through which the waste in a container (11) is arranged to be emptied and then moved with a pendulum (13) via a compacting aperture (15) to the collection container for further storage. The collection container (4) according to the invention features a primary press (16), with two positions, a first position substantially closing the compacting aperture (15) and a second position substantially freeing the compacting aperture (15). Wherein the primary press, it is closing position, makes it possible to compact voluminous waste.
