Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing container designs, particularly bottle caps, often result in litter due to separable caps and lack effective resealing mechanisms.

Innovation Solution

A bottle cap design featuring integrally molded or permanently affixed caps with mating structures and a pull tab mechanism that allows for easy opening and resealing without the need for additional tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If bottle caps are made separable for easy opening, then ease of operation is improved, but litter is generated and environmental harm increases

Engineering Contradiction:

Improveease of openingVSAvoidlitter

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The cap and bottle are merged into a single integrated structure where the cap cannot be completely separated from the bottle. The cap includes an integrally formed or permanently affixed structure that remains attached to the bottle body, eliminating loose cap litter while maintaining opening functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The cap is segmented into functional portions: a removable sealing portion for opening/closing operations and a permanent attachment portion that remains with the bottle. This segmentation allows easy opening while preventing complete separation and litter.

Inventive Principle:

Principle #1Segmentation

2Object-generated harmful factors

If bottle caps are permanently affixed to prevent litter, then environmental harm is reduced, but ease of operation deteriorates due to difficulty in opening and resealing

Engineering Contradiction:

Improvelitter preventionVSAvoidease of opening and resealing

Core Design Contradiction:

Object-generated harmful factorsVSEase of operation

Solution Approach 1:

The cap incorporates dynamic elements including a pull tab mechanism and resilient sealing portions that enable easy opening and resealing operations. The resilient material allows the sealing portion to flex and return to its sealing position, facilitating repeated opening and closing while the cap remains permanently attached to the bottle.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If traditional bottle caps are used without resealing mechanisms, then device complexity is reduced, but reliability deteriorates due to inability to reseal

Engineering Contradiction:

Improvecaps without resealing mechanismsVSAvoidresealing capability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The cap incorporates self-service resealing functionality through integrated sealing portions and pull tab mechanisms that enable the user to open and reseal the bottle without external tools or additional components. The resilient sealing portions automatically return to their sealing position when the cap is closed, providing reliable resealing through the cap's own structural properties.

Inventive Principle:

Principle #25Self-service

AI summary

Bottles include closures, such as corks, having a ring which seals against the inside surface of the bottle, allowing for the bottle to be opened, closed, and reopened. An annular channel in the closure seals against the outside bottle surface. A vertical channel in the closure fits on the rim of the bottle, allowing for the bottle closure to be secured and stored on the bottle while the bottle is open.
