Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for removing internal closures from containers, such as corks from bottles, require significant mechanical force, which can lead to cork damage, spillage, and potential injury, and existing devices are either complex or unreliable.

Innovation Solution

An apparatus and method involving a handle and worm assembly with a ram mechanism that applies force to advance the internal closure into the container to break the seal, using a fulcrum and push lock for better control and a ram to minimize damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional screw-type devices are used to remove internal closures, then the closure can be extracted from the container, but significant mechanical force is required which can lead to closure damage, spillage, and potential injury

Engineering Contradiction:

Improvesuccessful closure removalVSAvoidclosure damage and spillage risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Instead of pulling the closure directly outward which risks damage and spillage, the device first pushes the closure further into the container using a ram mechanism. This inversion of the extraction direction allows the seal to be broken in a controlled manner before removal, significantly reducing the risk of closure damage and liquid spillage while maintaining reliable extraction

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If traditional screw-type devices are used to remove internal closures, then the closure can be extracted from the container, but the device complexity increases with additional mechanisms like fulcrum and push lock

Engineering Contradiction:

Improvesuccessful closure removalVSAvoiddevice structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The device combines multiple functions into a single integrated tool: the worm assembly provides both the screw extraction mechanism and the push lock engagement, while the fulcrum serves as both a leverage point and a structural support for the ram mechanism. This merging of functions achieves reliable closure removal without requiring multiple separate components or overly complex mechanisms

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If traditional screw-type devices are used to remove internal closures, then the closure can be extracted from the container, but the force application is uncontrolled which can cause injury to persons or property

Engineering Contradiction:

Improvesuccessful closure removalVSAvoidsafe operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The device performs preliminary action by using the ram mechanism to push the closure further into the container and break the seal before the actual extraction occurs. This preliminary seal-breaking action reduces the force needed during removal and allows for controlled, gradual extraction, significantly improving safety and ease of operation while maintaining reliable closure removal

Inventive Principle:

Principle #10Preliminary action

AI summary

An apparatus and method includes a handle and a worm assembly, mechanically coupled to the handle, the worm assembly configured to extract an internal closure out of an opening in a container and having a straight portion, with one end of the straight portion coupled to the handle through a pivot point allowing rotational freedom between the handle and worm assembly and the other end coupled to a helical portion that is configured to be driven into the internal closure when a rotational force is applied to the handle. The worm assembly further includes a ram, coupled between the straight and helical portions, that applies force in a direction to advance the internal closure into the container over at least a portion of a top surface of the internal closure in order to break the seal between the internal closure and the container prior to extracting the internal closure.
