Solution Overview

Problem

Large garbage containers with hinged lids face issues during emptying, such as jamming with vehicle components, damage to the lid or vehicle, and interference with the pressing device, due to the lid opening during tilting and contact with garbage, which complicates the emptying process and can lead to damage.

Innovation Solution

A hinged lid design featuring a first and second partial lid element, where the second partial lid element is pivotably arranged on the first and can be fixed in an open position using a mechanical locking device, reducing the lid's contact area and preventing flapping during emptying, allowing it to yield under forces and avoid damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a hinged lid is used on a large refuse container, then the container can be easily closed and secured, but the lid opens during the tipping process and comes into contact with vehicle components and garbage, causing jamming and damage

Engineering Contradiction:
Improveease of closingVSAvoidlid stability during emptying
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The lid is divided into a first partial lid element that is articulated to the container body and a second partial lid element that is pivotally connected to the first partial lid element. This segmentation allows the second element to be independently positioned and fixed during emptying, preventing it from flapping and contacting vehicle components while maintaining the ease of closing function.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second partial lid element is pivotally connected to the first partial lid element before the emptying process begins. This preliminary configuration allows the lid structure to be prepared in advance so that during tipping, the second element can be positioned to avoid contact with garbage and vehicle components, preventing jamming before it occurs.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If the second partial lid element is pivotally connected to the first partial lid element, then the lid can adapt to different positions, but the second partial lid element swings back and forth freely during emptying, causing damage

Engineering Contradiction:
Improvelid position flexibilityVSAvoidlid structural integrity
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The lid system transitions from a static single-piece structure to a dynamic two-element system where the second partial lid element can pivot relative to the first. This dynamic configuration allows the lid to adapt to different positions during closing and emptying operations while maintaining structural integrity through controlled movement rather than rigid fixation.

Inventive Principle:
Principle #15Dynamics

AI summary

The cover has two cover part elements (23,24), where the latter cover part element is arranged at the former cover part element in a pivoted moving manner. A fixing unit (31) is provided for fixing the latter covering part element in an open position. The both cover part elements are connected with each other by a hinge connection (30). An independent claim is also included for a waste container, particularly large waste container, which has a waste container body.
