Solution Overview

Problem

Existing waste collecting devices face issues with stability in low-ceiling facilities, high energy consumption, and potential failure in low temperatures due to hydraulic systems, especially when lifting containers for unloading waste.

Innovation Solution

A waste collecting device with a compactor and ejector panel system that allows waste compaction and unloading without tilting the container, using a screw conveyor and movable ejector panel to push waste out, with a motor-driven mechanism for efficient operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a hydraulic piston is used to lift the container at an angle, then waste can flow out with gravity, but the device becomes unsuitable for low-ceiling facilities and raises stability issues due to high center of gravity

Engineering Contradiction:

Improvewaste discharge capabilityVSAvoidvehicle stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

Instead of lifting the container to discharge waste (conventional approach), this patent inverts the approach by keeping the container horizontal and using a movable ejector panel at the bottom to push waste out. The ejector panel moves between a retracted position (allowing waste accumulation) and an extended position (pushing waste out through discharge openings), eliminating the need for tilting and maintaining vehicle stability.

Inventive Principle:

Principle #13The other way round (Inversion)

2Productivity

If a hydraulic system is used for compaction and unloading, then waste can be processed, but the system becomes expensive, energy consuming, and prone to failure in low temperature conditions

Engineering Contradiction:

Improvewaste compaction and unloading capabilityVSAvoidsystem reliability in low temperature

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

This patent replaces the hydraulic mechanical system with a more reliable mechanism. The ejector panel is moved by a mechanical drive system (such as a screw mechanism or gear system) that is less sensitive to temperature variations. The compaction function is achieved through the same ejector panel mechanism that pushes waste out, combining both functions in a single mechanical system that operates reliably across temperature ranges.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If the container is tilted for waste discharge, then waste can flow out efficiently, but the center of gravity is raised high above ground creating stability risks

Engineering Contradiction:

Improvewaste discharge efficiencyVSAvoidcontainer stability

Core Design Contradiction:

ProductivityVSStability of the object's composition

Solution Approach 1:

Instead of tilting the container upward to discharge waste, this patent inverts the approach by keeping the container horizontal and using a bottom-mounted ejector panel to push waste out through discharge openings. The ejector panel's movement along the longitudinal axis allows efficient waste discharge while maintaining the container's horizontal position and low center of gravity.

Inventive Principle:

Principle #13The other way round (Inversion)

4Adaptability or versatility

If a movable ejector panel is used for waste discharge, then the device can operate in low-ceiling facilities, but the device complexity increases

Engineering Contradiction:

Improveadaptability to low-ceiling facilitiesVSAvoidejector panel mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The ejector panel is designed to perform multiple functions: it acts as both the compaction element (when in the retracted position, compressing waste against the container bottom) and the discharge mechanism (when in the extended position, pushing waste out through discharge openings). This multi-functionality reduces the need for separate hydraulic pistons and complex tilting mechanisms, thereby reducing overall device complexity while maintaining adaptability to low-ceiling facilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)
