Solution Overview

Problem

Conventional beverage cans cannot be resealed after opening, leading to carbonation loss, spoilage, and potential spills, which results in wastefulness and contamination risks.

Innovation Solution

A resealable beverage can lid design featuring a magnetized tab portion and closure element, allowing for easy resealing without specialized tools, using a scored opening mechanism that can be rotated to close the lid securely.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional beverage can lid is used, then the can can be opened easily, but the can cannot be resealed after opening

Engineering Contradiction:
Improveease of openingVSAvoidresealability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The lid is divided into functional segments: a tab portion for opening, a closure element for sealing, and a scored opening portion. The closure element can be independently positioned to seal the opening after use, while the tab remains attached for potential reuse.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The closure element is designed to be movable relative to the lid body, allowing it to transition between an open position (where it does not block the opening) and a closed position (where it seals the opening). This dynamic positioning enables both easy opening and effective resealing.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the scored opening portion is pushed into the can body to create an opening, then the can can be opened, but the opening cannot be closed again

Engineering Contradiction:
Improveease of openingVSAvoidstructural simplicity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The opening mechanism and closing mechanism are segmented into separate components: the tab portion with scored opening for creating the aperture, and the closure element for sealing it. This segmentation allows each component to perform its function independently without complicating the overall manufacturing process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The closure element acts as an intermediary component that mediates between the opened state and the sealed state. It is positioned over the opening created by the scored portion and provides a simple mechanical means to close the opening without requiring complex mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the tab portion is magnetized and connected to a closure element, then the can can be resealed, but the device complexity increases

Engineering Contradiction:
ImproveresealabilityVSAvoidmechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The magnetic field replaces complex mechanical linkages, springs, and latches. The magnetized tab portion and closure element interact through magnetic attraction to maintain the sealed position, eliminating the need for intricate mechanical retention mechanisms while ensuring reliable resealing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic attraction between the tab portion and closure element provides self-aligning and self-retaining functionality. When the closure element is positioned over the opening, magnetic forces automatically hold it in place without requiring additional mechanical fasteners or complex assembly steps.

Inventive Principle:
Principle #25Self-service
