Collapsible Refuse Bin With Twinned Wall Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current collapsible containers with twinned wall plastic components lack ease of storage and secure folding within the container when collapsed, and often lack weather resistance and side/top access in an erect position.
Innovation Solution
A collapsible container design featuring pivotally attached side and end walls with a twinned wall structure, allowing for secure storage and weather resistance, with optional lid for added protection, and incorporating concave indentations for increased rigidity and a slide lock mechanism for easy folding along a vertical axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wall components are pivotally attached along a horizontal hinge axis, then the container can collapse, but the components cannot be securely stored within the container when collapsed
Solution Approach 1:
The side walls are divided into multiple sections that can pivot relative to each other along vertical axes, allowing the walls to fold into compact configurations that can be securely stored within the container's periphery when collapsed
Solution Approach 2:
The patent introduces vertical hinge axes (perpendicular to the ground when erect) in addition to horizontal hinge axes, enabling wall sections to fold both horizontally and vertically. This multi-dimensional folding capability allows the walls to be compacted into a small space within the container's base periphery
2Weight of moving object
If the container is made from plastic components, then it is lightweight, but it lacks structural strength and rigidity
Solution Approach 1:
The patent employs twinned wall plastic components where two wall panels are joined together with reinforcing ribs positioned between them. This composite structure provides enhanced strength and rigidity while maintaining the lightweight advantage of plastic materials
Solution Approach 2:
The patent incorporates concave indentations in the wall components that create curved, arch-like structures. These curved features naturally distribute and resist applied loads, increasing the structural strength and rigidity of the plastic walls without adding significant weight
3Strength
If the container is made from twinned wall plastic components, then it is strong and lightweight, but the components cannot be easily and securely stored within the container when collapsed
Solution Approach 1:
The side walls are segmented into multiple pivotally connected sections that can fold independently along vertical axes, enabling the twinned wall components to be compacted into a small space within the container's periphery while maintaining their structural integrity
Solution Approach 2:
The patent employs pivotally attached wall sections with vertical hinge axes that allow dynamic folding and collapsing of the container. This dynamic mechanism enables easy transformation between the erected and collapsed states, facilitating simple storage of the strong twinned wall components within the container itself
4Ease of operation
If the container allows side and top access when erect, then usability is improved, but weather resistance and animal proofing are compromised
Solution Approach 1:
The lid is divided into multiple sections that can pivot independently along vertical hinge axes, allowing selective opening of portions of the lid. This enables users to access the container from the top or from the sides (by pivoting lid sections down) while keeping other portions closed to maintain weather resistance and animal proofing

AI summary
A collapsible refuse bin which has two ends walls and two side walls atop a base. The end walls, side walls and base are twinned wall plastic components. The side walls are made of two panels which are pivotally attached to one another along vertical axis. The end walls are pivotally attached to the base. The side walls engage a base along a tongue and groove means. Side walls and end walls have mutually engaging edges. Removal of the side walls followed by folding down the end walls converts the refuse bin to a collapsed position.
