Solution Overview

Problem

Existing refuse collection systems face issues with loose coupling between containers and lifting devices, leading to inconvenient and noisy emptying processes, especially in crowded areas, where a sturdy and noise-reduced connection is necessary.

Innovation Solution

The implementation of bayonet-type coupling means with elongate slots and rotatable locking members, along with support plates and displaceable reinforcements, provides a stiff and reliable connection between the refuse collection container and the lifting device, allowing for easy and efficient coupling from various directions, reducing noise and play.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional coupling means are used to connect the refuse collection container and lifting device, then the coupling process is simple, but the connection becomes loose with play, causing noise and inconvenience during lifting and turning

Engineering Contradiction:

Improveconnection stabilityVSAvoidnoise generation

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The coupling system employs rotatable locking members that can rotate into locked positions within elongate slots, transforming a static loose connection into a dynamic system that adapts from approach to locked connection, eliminating play while maintaining coupling simplicity

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The bayonet-type coupling means acts as an intermediary mechanism between the container and lifting device, providing a stiff connecting structure that mediates the connection and eliminates the loose coupling and noise generation of conventional systems

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If conventional coupling means are used to connect the refuse collection container and lifting device, then the coupling structure is simple, but play between components makes lifting and turning inconvenient

Engineering Contradiction:

Solution Approach 1:

The rotatable locking members provide a dynamic coupling mechanism that transitions from approach to locked position, ensuring stiffness during lifting and turning operations while maintaining ease of coupling through rotational motion

Inventive Principle:

Solution Approach 2:

The coupling system is segmented into coupling supports with elongate slots and separate rotatable locking members, allowing independent optimization of each component to provide both ease of operation and coupling stiffness

Inventive Principle:
