Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing environmental and humanitarian issues caused by the disposal of plastic bottles, particularly PET plastic, due to their limited recyclability and tendency to end up in landfills and oceans, necessitate a solution that promotes recycling and reuse.
Innovation Solution
Development of scalable, modular, and interlocking containers made from materials like PET that can be used for storing and transporting liquids, serving as building materials, and easily assembled into structures, thereby encouraging recycling and reducing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If plastic bottles are disposed of after use, then consumers have convenient access to single-use containers, but environmental degradation and waste accumulation occur
Solution Approach 1:
The container is divided into modular segments that can be separated and reconfigured. The body portion can be detached from the closure assembly, allowing the container to be disassembled for recycling while maintaining ease of use during its service life. This segmentation enables the container to transition from a single-use disposable item to a recyclable component system.
Solution Approach 2:
The container design incorporates multiple functional capabilities: it serves as a beverage container, a building block, and a recyclable material source. The modular segments can be reused for different purposes after their primary function, reducing waste. The container can be stacked with other containers or used as construction elements, extending its useful life beyond single-use disposal.
2Object-generated harmful factors
If plastic bottles are made recyclable, then environmental waste is reduced, but manufacturing complexity and cost increase
Solution Approach 1:
By segmenting the container into standardized modular portions (body, closure, ring assembly), each component can be independently recycled through established processes. The segmentation uses common connection interfaces that simplify disassembly during recycling, reducing the complexity burden despite the modular design.
Solution Approach 2:
The container employs parameter optimization in its modular design, using standardized dimensions and material specifications that align with existing recycling infrastructure. The materials selected for each segment are chosen for their recyclability within current systems, balancing complexity with practical recycling feasibility.
3Stability of the object's composition
If containers are designed for lateral interlocking, then structural stability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The interlocking mechanism uses asymmetric geometries with tapered surfaces and complementary male-female interfaces. This asymmetry provides self-aligning characteristics that tolerate minor manufacturing variations, achieving stable connections without requiring extremely tight tolerances. The asymmetric design ensures proper orientation during assembly while maintaining stability.
Solution Approach 2:
The interlocking features incorporate curved and rounded surfaces rather than sharp edges, allowing for smoother engagement and accommodation of manufacturing tolerances. The curved interfaces provide gradual contact areas that distribute stresses and reduce sensitivity to precision variations, maintaining structural stability while easing manufacturing requirements.

AI summary
Described are devices and containers that are scalable, modular, and lockable laterally and vertically with other like containers for a variety of applications. A container is formed by a wall attached at first end to a top end section with an opening and attached at a second end by a bottom end section. A container may have one or more of a tongue, formed on the wall, having and interconnecting mechanism to be received and interlocked by a groove. Vertical interconnectivity is accomplished with mechanisms to stack containers and prevent swivel using a ridge and channel interlocking arrangement.
