Corkscrew Lever Coupling System for Stable Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corkscrews with double propping levers face issues such as unstable support during cork extraction, leading to premature wear and potential cork breakage due to non-vertical extraction, and interference between levers that can prevent complete cork removal.
Innovation Solution
A corkscrew design featuring a coupling system between two levers using slots and pins that allows for a translation movement, ensuring the second lever is in a stable position during extraction, preventing interference and maintaining a vertical cork trajectory, thus enhancing stability and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two independent propping levers are hinged at the same pivot point, then the corkscrew can provide propping support during cork extraction, but the levers interfere with each other and cause unstable support leading to premature wear and potential cork breakage
Solution Approach 1:
The single common pivot point is segmented into two separate pivot points, one for each lever. This segmentation eliminates the interference between levers while maintaining the propping function, resolving the contradiction between reliability and device complexity
Solution Approach 2:
A coupling element is introduced as an intermediary between the two levers. This coupling element coordinates the movement of both levers independently, ensuring stable propping support without direct interference between the levers themselves
2Device complexity
If the levers are freely rotatable on the pivot point independently of each other, then the structure is simple, but the support is unstable causing lateral sliding of the propping tooth
Solution Approach 1:
The coupling element acts as an intermediary that connects the two independently rotatable levers, providing coordination and stability. This maintains the simplicity of independent rotation while preventing lateral sliding through the coupling mechanism
Solution Approach 2:
The system changes from completely independent free rotation to coupled rotation where the relationship between lever positions is controlled. This parameter change in rotational freedom achieves stable propping tooth engagement
3Reliability
If the first lever remains in position after initial propping, then it provides stable support for the first phase extraction, but it interferes with the second lever during the final extraction phase
Solution Approach 1:
The levers transition from static fixed positions to dynamic positions that change during operation. The coupling element enables the levers to move relative to each other, allowing the first lever to clear the cork path while the second lever completes extraction
Solution Approach 2:
The first lever performs preliminary propping action and then automatically moves out of the way through the coupling mechanism, preparing the system for the second lever's final extraction action without manual intervention

AI summary
Corkscrew for the extraction of a cork from the neck of a bottle, wherein the corkscrew has a body, an extraction screw, an articulated lever having a first lever and a second lever, which are coupled with each other by a coupling system with at least one set of slots, a set of pins and a set of holes, which guide the reciprocal movement of the second lever with respect to the first lever.
