Collapsible Refuse Container Extension Frame for Handling and Lid Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large refuse containers are difficult to maneuver due to their size and weight, often resulting in splashing of grime and water, animal access, and potential tipping, leading to messy cleanups and waste dispersal.
Innovation Solution
An extension device with a central frame, handle, lid securement, and locking mechanism that provides mechanical advantage and secures the lid, preventing opening and providing stability during handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If large-wheeled bins with hinged lids are used to increase capacity, then waste storage capacity is improved, but ease of operation deteriorates due to difficulty in transitioning and moving the container
Solution Approach 1:
The extension device is divided into multiple functional segments: a handle section with upper and lower frame arms for gripping and lifting, articulating frame arms for connection, and a lid securement section with locking tabs. This segmentation allows each component to perform its specific function efficiently while working together to solve the overall problem of moving large containers.
Solution Approach 2:
The extension device acts as an intermediary mechanical system between the user and the heavy refuse container. By attaching to the container's existing handle and lid mechanism, it provides additional leverage and control, enabling users to safely and easily maneuver containers that would otherwise be too heavy and unwieldy.
2Strength
If the handle is positioned close to the side of the container to support the hinged lid mechanism, then structural integrity is improved, but ease of operation deteriorates due to difficulty in gripping and moving
Solution Approach 1:
The extension device extends the handle functionality into a new spatial dimension by adding upper frame arms that project outward from the container side. This creates a lever arm that provides both structural support for the lid mechanism and an ergonomic gripping surface远离 the container body, solving both the strength and ease of operation requirements.
3Volume of stationary object
If large-wheeled bins are used for waste storage, then waste storage capacity is improved, but object-generated harmful factors worsen due to splashing of water and grime onto users
Solution Approach 1:
The extension device serves as a protective intermediary between the user and the container. By providing extended handle arms and a secure gripping mechanism, it allows users to maintain greater distance from the container during handling operations, preventing water and grime splashes from reaching the user while still enabling effective control of the heavy container.
4Productivity
If containers are not emptied for several days, then productivity is improved by reducing collection visits, but object-generated harmful factors worsen due to animal access and potential tipping
Solution Approach 1:
The lid securement section with locking tabs implements preliminary anti-action by proactively securing the lid in the closed position before animals or external forces can cause opening or tipping. The locking mechanism prevents these harmful events from occurring during the several-day storage period, maintaining sanitation and preventing waste dispersal.
5Reliability
If the lid securement mechanism is added to prevent animal access and tipping, then reliability is improved, but device complexity increases
Solution Approach 1:
The lid securement function is merged with the existing extension device structure. The locking tabs are integrated into the frame arms, and the securement mechanism utilizes the same articulating joints and connection points already present in the design. This merging approach provides reliable lid security without significantly increasing overall device complexity.
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
Facilitates easy maneuvering of refuse containers while keeping grime off users and preventing animal access and spillage, even when knocked over.
Implementation Method 1
The handle section can provide a gripping surface for a user and can provide separation distance between the user and the container. The vertical support legs can extend downward from the frame and can work in conjunction with the handle to provide a mechanical advantage when tilting and/or moving the refuse container.

AI summary
An extension device for a refuse container includes a central frame section having a pair of upper frame arms, a pair of lower frame arms and a pair of articulating frame arms. The frame section includes a shape and a size that designed to be compatible with commercial grade refuse containers. An extendable handle section is connected to the pair of upper frame arms, a pair of extendable support legs are connected to the pair of lower frame members, and a pair of extendable lid securement arms are connected to the pair of articulating frame arms and secure the lid of the refuse container in the closed position. Locking tabs located along the pair of lower frame arms secure the device onto the refuse container. The device transitions between a fully extended position for engagement with the refuse container and a fully collapsed position for storage.
