Aluminium Frame Waste Container with Cardboard Repository
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plastic waste containers face issues with cleaning complexity and high maintenance costs due to non-recyclable materials, while recyclable cardboard containers lack stability and strength, and existing solutions with metal frames are rigid and not versatile.
Innovation Solution
A container design comprising an aluminium support structure and a cardboard repository, featuring a modular, recyclable, and stable structure with a magnetic cover system, allowing both rear and side loading, and incorporating advertising surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional plastic containers are used, then impermeability to liquid waste is improved, but cleaning complexity and maintenance cost increase
Solution Approach 1:
The container is divided into two distinct parts: a plastic base structure that provides impermeability and a removable cardboard insert that contains the waste. This segmentation allows the cardboard insert to be easily removed and replaced, simplifying cleaning operations while the plastic base maintains its protective impermeable properties.
Solution Approach 2:
The cardboard repository is designed as a disposable or frequently replaceable component. When soiled with organic waste, it can be discarded and composted along with the waste, eliminating the need for complex cleaning processes while the permanent plastic structure continues to provide structural support and impermeability.
2Adaptability or versatility
If recyclable cardboard containers are used, then recyclability and environmental friendliness are improved, but stability and strength deteriorate
Solution Approach 1:
The container combines two different materials with complementary properties: cardboard provides recyclability and environmental benefits, while the plastic base structure provides strength, stability, and impermeability. This composite approach allows both materials to contribute their advantageous properties to the overall system.
Solution Approach 2:
By separating the container into a permanent plastic structural framework and a removable cardboard repository, the design allows the cardboard to be optimized for recyclability while the plastic framework maintains structural integrity and stability throughout the container's life.
3Strength
If metal frame structures are used, then stability and strength are improved, but rigidity and versatility deteriorate
Solution Approach 1:
The container design incorporates removable and replaceable components, particularly the cardboard repository that can be easily taken out and replaced. This dynamic design allows the container to adapt to different uses and maintenance needs, contrasting with rigid metal frame structures that are difficult to modify or replace.
Solution Approach 2:
The plastic base structure serves multiple functions: providing structural support, ensuring impermeability, and accommodating various removable repository types. This multi-functionality increases versatility while maintaining stability, unlike specialized metal frame designs that are optimized for a single configuration.
4Object-affected harmful factors
If plastic containers are used, then impermeability is improved, but maintenance cost increases
Solution Approach 1:
The cardboard repository is designed to be replaced rather than cleaned when soiled. This disposable approach eliminates expensive cleaning operations involving chemical products and large water quantities, while the permanent plastic base structure requires minimal maintenance due to its durability and impermeability.
Solution Approach 2:
The cardboard repository can be discarded after use and recovered through composting along with the organic waste it contained. This eliminates the need for costly cleaning and maintenance operations while the plastic base structure continues to provide long-term service with minimal maintenance requirements.

AI summary
Disclosed is a container for collecting urban waste, formed from an aluminium support structure that contains and protects a cardboard repository, which is characterised in that it comprises: a support structure comprising an external housing frame formed by a series of straight profiles and a flippable circular profile that forms the front access or entry of the container for the introduction of waste; a flippable circular plate or opening that closes the front access generated by the circular profile; a removable flippable cover that closes the frame assembly, the cover being able to flip open by means of gravity when the container is turned over; a bottom grate; and a cardboard repository contained in and supported by the housing frame, which is formed from cardboard sheets with flat folded faces.
