Solution Overview

Problem

Existing waste compactors require significant investment and operational constraints, including the need to move skips and position mechanical arms for optimal compaction, which is inefficient and costly, especially when dealing with skips of varying shapes and sizes.

Innovation Solution

A compacting roller with a rotatable frame that can orient itself relative to a mechanical arm, allowing for adaptable compaction of waste in dumpsters of different shapes, using a stirrup-shaped frame, direct motor transmission, and hydraulic actuation for efficient power and longevity, enabling compaction of waste in a flexible and robust manner.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed compactor is used, then compaction can be performed, but the skip must be moved and positioned in the longitudinal axis of the mechanical arm, which reduces operational efficiency and increases time loss

Engineering Contradiction:
Improvecompaction capabilityVSAvoidtime for moving and positioning skip
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Instead of moving the skip to the compactor, the compactor is made mobile and moves to the skip. The mechanical arm with the compactor travels along the platform to reach different skips, inverting the traditional fixed compactor approach and eliminating the need to reposition skips.

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

Solution Approach 2:

The compactor is transformed from a fixed structure to a mobile system. The mechanical arm can dynamically position the compactor at different locations along the platform, allowing flexible access to multiple skips without requiring skip movement.

Inventive Principle:
Principle #15Dynamics

2Productivity

If a mechanical arm positions the compactor for optimal compaction, then compaction effectiveness is improved, but the system complexity and investment cost increase

Engineering Contradiction:
Improvecompaction efficiencyVSAvoidmechanical arm system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The mechanical arm is designed as a multi-functional device that can perform both compaction operations and transport operations. This universal design allows the same equipment to serve multiple purposes, reducing overall system complexity and investment requirements while maintaining compaction efficiency.

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

3Ease of operation

If the compactor is positioned at one end of the bucket in the axis of the mechanical arm, then longitudinal to-and-fro movements can be performed, but this limits adaptability to different skip shapes and sizes

Engineering Contradiction:
Improvelongitudinal compaction operationVSAvoidadaptability to different skip shapes
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The mechanical arm can dynamically adjust its position and orientation to access different parts of various skip shapes. The compactor can operate not only in longitudinal movements but also in lateral and diagonal trajectories, adapting to rectangular, circular, or irregular skip geometries.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The compaction operation is extended from one-dimensional longitudinal movements to two-dimensional or three-dimensional trajectories. The mechanical arm can move the compactor in multiple directions (longitudinal, lateral, diagonal) to effectively compact waste in skips of various shapes and sizes.

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