Solution Overview

Problem

Current compacting apparatuses for waste material are voluminous and inefficient, limiting their capacity to handle large volumes of waste while occupying excessive space, and lack a simple, reliable, and cost-effective solution for compacting waste in small spaces like households and industries.

Innovation Solution

A compacting apparatus with an arcuate compression chamber and a press plunger that pivots externally, allowing a large moving angle and efficient compression, minimizing the machine's volume while maximizing waste handling capacity, featuring a power transmission mechanism with a connecting member and an output module for easy waste collection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the press plunger is arranged with an axis inside the compression chamber, then the mechanism occupies less space, but the moving angle is limited and the compression chamber size is restricted

Engineering Contradiction:
Improvecompression chamber volumeVSAvoidpress plunger moving angle
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The axis of the press plunger is inverted from being inside the compression chamber to being outside the compression chamber. This inversion allows the press plunger to achieve a larger moving angle (greater than 90 degrees) while the mechanism still occupies compact space through the external axis arrangement and arcuate channel design.

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

2Device complexity

If a traditional power transmission mechanism is used, then the structure is simple, but the mechanism takes much space in the machine

Engineering Contradiction:
Improvepower transmission mechanism structureVSAvoidtotal machine volume
Core Design Contradiction:
Device complexityVSVolume of moving object

Solution Approach 1:

The power transmission mechanism is merged with the compression chamber structure through the arcuate channel design. The arcuate channel serves both as the compression path and as part of the power transmission system, eliminating the need for separate, space-consuming transmission components while maintaining structural simplicity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The compression chamber is designed with an arcuate (curved) channel instead of a straight channel. This curvature allows the press plunger to move through a larger angle while following the arcuate path, reducing the overall space required for the mechanism while maintaining effective compression capability.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Ease of manufacture

If the compression chamber is designed with straight walls, then the manufacturing is simpler, but the compression efficiency for large volumes is reduced

Engineering Contradiction:
Improvecompression chamber constructionVSAvoidwaste handling capacity
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The compression chamber employs arcuate (curved) walls instead of straight walls. This curvature enables the press plunger to traverse a larger compression path, increasing the compression volume and handling capacity. The arcuate design, while slightly more complex to manufacture, provides significantly improved productivity for waste material compression.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

A compacting apparatus (1) and method for compressing waste material comprising: A filling opening (3), filling chamber (2), a compression chamber (4) and a press plunger (7). The press plunger (7) is moved from a first position to a second position by the activating of a power supply (14). The compression chamber (4) is formed as a uniformly arcuate channel (11) comprising an arcuate front wall (5), an arcuate rear wall (6) both having a sectional view formed as an arc. They are concentric with each other. The press plunger (7) follows the arcuate channel following and substantially touches the entire inner surface of the arcuate channel (11). The press plunger (7) is pivotally arranged about an axis (18) placed outside the compression chamber (4).
