Collapsible Bin with Rigid Frame and Hinged Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waste collection bins used at events and temporary locations are prone to toppling in winds, disintegrating in rain or snow, and lack stability, often requiring external weights that can cause them to tip over during relocation, and are typically made of cardboard that ends up in landfills after use.
Innovation Solution
A reusable, collapsible bin design featuring a top piece, bottom piece, and side pieces with central hinges that allow the bin to fold in half for easy transport and storage, with integrated handles and a secure fastener system for liners, constructed from durable materials to withstand environmental challenges and wildlife protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If cardboard bins are used for waste collection at events, then they are lightweight and easy to manufacture, but they topple in light winds and disintegrate in rain or snow
Solution Approach 1:
The bin is constructed from a composite structure combining a rigid frame (metal or heavy-duty plastic) with a flexible liner bag, creating a hybrid material system that provides both structural strength and weather resistance while maintaining ease of manufacturing through modular assembly
2Stability of the object's composition
If rocks are used to weight the bin down to counter wind, then stability in wind is improved, but the bin blows out the bottom during relocation
Solution Approach 1:
The bin employs dynamic stability through its rigid frame structure that maintains structural integrity during both stationary use and relocation, eliminating the need for external weights while preventing bottom blowout during movement
Solution Approach 2:
Instead of using external rocks as counterweights, the design integrates weight distribution into the rigid frame structure itself, which provides inherent stability against wind forces without compromising mobility during relocation
3Volume of moving object
If the bin is made collapsible for easy transport, then storage efficiency is improved, but structural integrity may be compromised
Solution Approach 1:
The bin is segmented into a rigid frame structure and a separate flexible liner bag, allowing the frame to collapse for compact storage while the liner can be removed and reused, maintaining structural integrity when assembled
Solution Approach 2:
The flexible liner bag serves as a thin-film containment structure that can be easily stored when empty, while the rigid frame provides the necessary structural integrity when the bin is in use, combining collapsibility with strength
4Object-affected harmful factors
If cardboard lids are pushed on top of the bin, then coverage is provided, but they are never stable
Solution Approach 1:
The lid system uses a rigid frame component that integrates with the bin structure and a secure fastening mechanism, providing stable waste protection unlike the loose cardboard lids of traditional designs

AI summary
A reusable, multi-purpose collection bin for waste collection, particularly at special events requiring waste collection such as concerts, festivals, sporting events, and any other outdoor or indoor event where trash collection is desired. The bin easily contracts simply by pulling upward on the top panels through the grasping holes on the top of the bin.
