Solution Overview

Problem

Existing waste collection devices in public spaces are cumbersome and require significant effort to pivot from filling to emptying positions, leading to potential waste spillage and injury risks due to their heavy and massive design.

Innovation Solution

A waste collection device with a pivotably mounted waste container and an inner container, utilizing a locking mechanism and a pneumatic or hydropneumatic pivoting means with adjustable damping to facilitate easier and controlled pivoting, allowing for a reduced pivoting angle of less than 90°, thereby simplifying the emptying process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If the waste container is made massive and robust for durability, then the service life is extended, but the pivoting effort increases significantly

Engineering Contradiction:
Improveservice lifeVSAvoidpivoting effort
Core Design Contradiction:
Duration of action of stationary objectVSEase of operation

Solution Approach 1:

The waste container is divided into two parts: an outer waste container (2) that remains fixed and robust for durability, and an inner container (4) that is lighter and can be easily removed. This segmentation allows the heavy outer container to provide structural strength while the lighter inner container handles the pivoting and emptying operations, reducing the effort required.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner container (4) is extracted as a separate removable component from the outer waste container (2). This extracted inner container can be easily pivoted and removed for emptying, while the outer container remains in place, solving the contradiction between robustness and ease of operation.

Inventive Principle:
Principle #2Taking out (Extraction)

2Strength

If the waste container is made heavy for structural integrity, then the container is more durable, but the risk of waste spillage and injury increases

Engineering Contradiction:
Improvestructural integrityVSAvoidwaste spillage and injury risk
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

By segmenting the container into a fixed outer container (2) and a removable inner container (4), the heavy outer container provides structural integrity while the lighter inner container can be safely handled and removed. This reduces the risk of waste spillage and injury associated with moving heavy containers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner container (4) acts as an intermediary between the heavy outer container (2) and the emptying process. It can be easily removed and emptied without requiring the movement of the entire heavy outer container, thereby reducing the risk of waste spillage and injury.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the waste container is pivoted by more than 90° for complete emptying, then the waste can exit completely, but the pivoting control becomes difficult

Engineering Contradiction:
Improveemptying completenessVSAvoidpivoting control
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The inner container (4) is extracted and removed from the outer container (2) after a limited pivoting movement. This allows complete emptying without requiring the outer container to be pivoted by more than 90°, maintaining pivoting control while achieving complete waste removal.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The inner container (4) is preliminarily positioned and secured in the outer container (2) during the pivoting process. This preliminary arrangement allows the inner container to be easily removed and emptied after a limited pivoting angle, achieving complete emptying without excessive pivoting.

Inventive Principle:
Principle #10Preliminary action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables easier and safer emptying of waste without great effort, reducing the risk of waste spillage and injury, while ensuring secure access through a locking mechanism and efficient use of space with a spring-loaded and damped pivoting mechanism.

Implementation Method 1

a gas pressure spring 9 can be used as the pivoting means 9 as a hydropneumatic pivoting means 9. Adjusting the filling pressure of such a gas pressure spring 9 allows the pressure force that can be applied by the gas pressure spring 9 for pivoting to be varied.

Methodology Applied
Scientific EffectGas pressure: Pressure Increase

Implementation Method 2

The pivoting means 9 is formed here by an adjustable damping cylinder 9 as a pneumatic pivoting means, which includes a pressure tube 90 and a piston rod 91. The damping cylinder 9 is filled with oil, for example, and prevents uncontrolled pivoting of the waste container 2 about the pivot axis 5.

Methodology Applied
Scientific EffectDamping: Damping

Implementation Method 3

a gas pressure spring 9 can be used as the pivoting means 9 as a hydropneumatic pivoting means 9

Methodology Applied
Scientific EffectHydraulic pressure: Hydraulic Press

AI summary

The device (1) has a waste container (2) with an upper discharge opening, and a pivotal hinge (6) arranged at the waste container, so that the waste container is pivotably supported from filling position to emptying position around a pivot axis (5) running perpendicular to a longitudinal axis (L). A holding profile (10) designed as a U-profile is articulatedly connected at the waste container over the hinge. The hinge, a pivoting unit (9) e.g. adjustable damping cylinder, and a locking device (8) are placed in the holding profile.
