Foldable Collection Bin with Hinged Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waste collection bins, typically made of cardboard, are prone to toppling in winds, disintegrating in rain or snow, and lack stability, leading to spills and difficulties in relocation, with inadequate fastening for liners and poor durability, resulting in environmental impact from disposal.
Innovation Solution
A reusable, collapsible bin with a central hinge system allowing for easy folding and storage, featuring strategically cut handles, secure fasteners for liners, and a locking top piece to prevent spills, constructed from durable materials to withstand environmental challenges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a cardboard bin is used for waste collection, then it is lightweight and easy to manufacture, but it topples in light winds and disintegrates in rain or snow
Solution Approach 1:
The bin material is changed from cardboard to a durable plastic composition, fundamentally altering the physical parameters of the bin to achieve weather resistance and structural stability while maintaining lightweight properties through the specific plastic formulation
Solution Approach 2:
The bin is constructed from a composite plastic material that combines multiple properties: durability against weather elements, lightweight characteristics, and flexibility for folding. This composite material resolves the contradiction between light weight and reliability
2Stability of the object's composition
If a rock is used to weight the bin down to counter wind, then the bin becomes more stable, but the bottom blows out from the weight of refuse or the rock
Solution Approach 1:
The bin bottom is designed with increased strength through the durable plastic construction, allowing it to support the weight of rocks for ballast without blowing out. The material parameters are changed to accommodate the additional weight while maintaining overall bin integrity
Solution Approach 2:
The design explicitly incorporates ballast rocks as a counterweight mechanism to prevent the bin from toppling in wind, resolving the stability issue while the strengthened bottom accommodates this counterweight solution
3Reliability
If the bin is made rigid for durability, then it withstands environmental challenges, but it becomes difficult to transport and store
Solution Approach 1:
The bin incorporates a dynamic folding mechanism with hinges that allow it to transition between a rigid, durable configuration for use and a compact, flexible configuration for transport and storage. This dynamic capability resolves the contradiction between rigidity for durability and flexibility for portability
Solution Approach 2:
The bin is segmented into multiple panels connected by hinges, allowing it to be folded into a compact form factor for easy transport and storage while maintaining structural integrity and durability when deployed in its expanded configuration
4Device complexity
If no fastener is used for the liner, then the bin structure remains simple, but the liner rarely fastens well to the rim
Solution Approach 1:
The bin rim is designed with self-fastening features such as integrated clips or gripper elements that automatically secure the liner when placed in position, eliminating the need for separate fasteners while ensuring reliable liner attachment through the self-service mechanism

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 (10) through the grasping holes (13) on the top of the bin.
