Solution Overview

Problem

Wheeled waste containers are prone to being knocked over by animals or strong winds, especially when left outdoors, leading to nuisance and potential spillage.

Innovation Solution

An anti-rollover device that immobilizes a laterally projecting handle of the container to a vertical support using a cage with a longitudinal housing and a closing mechanism, allowing the handle to be secured without lifting the container.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a U-shaped hook retaining device is used to immobilize the container handle, then the container can be secured to a vertical support, but the container must be lifted to insert the handle into the hook, which is cumbersome and inconvenient

Engineering Contradiction:
Improvecontainer stabilityVSAvoidhandle insertion ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

Instead of requiring the handle to be inserted upward into a hook (as in prior art), the invention inverts the approach by providing a longitudinal housing that receives the handle horizontally as the container is rolled into position. The closing means then secures the handle from above, reversing the insertion direction and eliminating the need to lift the container.

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

Solution Approach 2:

The invention introduces a closing means as an intermediary element that actively secures the handle within the longitudinal housing. This closing means acts as a mediator between the handle and the vertical support, providing reliable immobilization through a automated closing action rather than requiring manual insertion into a passive hook structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the container is lifted to insert the handle into the retaining device, then the handle can be secured in the retaining device, but this requires additional physical effort and time

Engineering Contradiction:
Improvehandle immobilizationVSAvoidtime to secure container
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The longitudinal housing is pre-positioned on the vertical support at the appropriate height and orientation. As the container is rolled into place, the handle automatically aligns with and enters the pre-prepared housing, eliminating the need for lifting and manual insertion operations that consume time and effort.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system is designed so that the container's own movement (rolling into position) performs the insertion action. The handle automatically enters the longitudinal housing through the container's rolling motion, making the securing process self-service rather than requiring external manual intervention to lift and insert the handle.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If a lateral opening is provided in the cage for handle insertion, then the handle can be inserted by rolling the container, but the opening must be closed to ensure proper immobilization

Engineering Contradiction:
Improvehandle insertion easeVSAvoidcage structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The closing means transforms the static cage structure into a dynamic system. The lateral opening is not merely a fixed hole but is controlled by a closing means that can open to allow handle insertion and then close to secure the handle. This dynamic element adds functionality without significantly increasing overall structural complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The closing means serves multiple functions: it closes the lateral opening to secure the handle, provides a locking mechanism to prevent handle removal, and can be designed to allow easy opening for container removal when needed. This multi-functional element justifies the added complexity by delivering multiple operational benefits from a single structural addition.

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

AI summary

Anti-rollover device (1) for a wheeled container (CR) configured to immobilize a handle (PG) of the container, projecting laterally, to a vertical support (SV) such as a wall (M) or furniture extending vertically from a floor, said anti-rollover device comprising: - at least a first cage (Ca1) and preferably a second cage (Ca2) spaced apart from each other by a free clearance (DG) each comprising an upper wall (10), a lower wall (11), a bottom wall (12) defining a groove forming a longitudinal housing (LG) for a horizontal bar of the handle, the groove having a lateral opening (OL) to allow insertion of the horizontal bar of the handle into the groove, - a first closing means (131) and preferably a second closing means (132) synchronized by a mechanical link (LI),The locking mechanisms are configured to transition from an open state (EO) to a closed state (EF) of the lateral opening, ensuring that the handle is immobilized.
