Corkscrew Paddles Grip Cork to Prevent Fracture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When opening a wine bottle, corks often fracture or break, making extraction difficult and causing bits of cork to fall into the wine, which can affect the taste and enjoyment of the wine, and the screw portion of a corkscrew may penetrate the cork, leading to further debris in the bottle.
Innovation Solution
A corkscrew with a screw shaft and pair of wings that lift the screw shaft when compressed, along with a housing and paddles that grip the cork to prevent it from breaking and falling into the bottle, ensuring controlled leverage and cork integrity during removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional corkscrew is used to extract the cork, then the cork can be removed from the bottle, but the cork may fracture or break apart during extraction
Solution Approach 1:
The corkscrew is divided into functional segments: a screw shaft for penetration, a collar for positioning, and paddles for cork support. This segmentation allows each component to perform its specific function, with the paddles providing support to prevent fracture while the screw shaft enables extraction.
Solution Approach 2:
The paddles act as an intermediary element between the screw shaft and the cork. They provide a support surface that distributes the extraction forces, preventing direct stress concentration on the cork that would cause fracture, while still allowing the screw to effectively pull the cork out.
2Force
If the screw portion penetrates deeply into the cork to ensure grip, then extraction force is improved, but the screw may penetrate the bottom of the cork causing debris to fall into the wine
Solution Approach 1:
The paddles are positioned to engage the cork before the screw shaft penetrates the bottom. This preliminary support action prevents the screw from going too deep by providing an earlier grip point, ensuring sufficient extraction force while avoiding cork debris generation.
3Device complexity
If the cork is pulled directly by the screw shaft without additional support, then the extraction process is simple, but the cork becomes more difficult to extract fully when it breaks
Solution Approach 1:
The patent merges the screw shaft function with the paddle support system into a single integrated device. The paddles are attached to the collar structure, combining the penetration, support, and extraction functions into one unified mechanism that works together to ensure complete cork removal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The corkscrew effectively lifts the cork without breaking it, preventing debris from entering the wine and ensuring a clean extraction, maintaining the quality and enjoyment of the wine.
Implementation Method 1
The pair of paddles are connected to the housing in a manner to urge the pair of paddles radially inwardly when the pair of paddles are forced to move radially outwardly
Implementation Method 2
a pair of wings configured to lift the screw shaft when the pair of wings is compressed
