Solution Overview

Problem

Existing bottle openers for effervescent liquids like sparkling wine or champagne pose safety risks due to the cork being propelled as a projectile upon release, requiring manual dexterity and effort, and often necessitate risky steps like removing the wire cage before venting.

Innovation Solution

A bottle opener with retaining and damping means that secure the cork during extraction, allowing controlled gas release and minimizing manual effort by utilizing the cork's energy, featuring a guide foot, damping chamber, and tilting mechanism to manage the cork's movement safely.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional bottle opener is used to open a sparkling wine bottle, then the capsule and crown cork are removed, but the sparkling liquid spills out and foam is generated

Engineering Contradiction:
Improveease of openingVSAvoidliquid spill and foam generation
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent applies preliminary action by providing a cover that is already in place on the bottle before opening. This cover prevents the harmful effects (spill and foam) from occurring in the first place, rather than trying to deal with them after they occur during the opening process

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The cover acts as an intermediary element between the sparkling liquid and the external environment. It mediates the opening process by containing the liquid and preventing direct exposure to air, thereby eliminating foam generation and spillage while still allowing the bottle to be opened

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the bottle is opened quickly to serve guests promptly, then service speed is improved, but liquid spill and foam generation occur

Engineering Contradiction:
Improveservice speedVSAvoidliquid spill and foam generation
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The cover is placed on the bottle in advance, before the opening operation. This preliminary protective measure allows the bottle to be opened quickly without risk of spill or foam, thus maintaining high service speed while preventing harmful effects

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention converts the potential harm of quick opening (which causes spill and foam) into a benefit by using the cover to contain any pressure release. The quick opening action is maintained, but the harmful effects are transformed into controlled venting under the cover

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Object-generated harmful factors

If a cover is added to prevent liquid spill and foam, then harmful effects are reduced, but device complexity increases

Engineering Contradiction:
Improveliquid spill and foam generationVSAvoidbottle opening system complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The cover is designed to perform multiple functions: it prevents liquid spill, prevents foam generation, and can be integrated with the bottle opener mechanism. By combining these functions into a single component, the overall device complexity is minimized while achieving multiple protective benefits

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the cover with the bottle opener system, integrating the protective function into the existing opening mechanism. This combination eliminates the need for separate protective devices, thereby reducing overall device complexity while maintaining spill and foam prevention

Inventive Principle:
Principle #5Merging (Combining)

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 opener ensures safe and effortless bottle opening by preventing cork ejection and reducing manual force required, utilizing the cork's energy for extraction, and controlling gas release, thus enhancing user safety and ease of use.

AI summary

The invention relates to a bottle opener which is configured to remove a cork (10) from a bottle (1) containing a sparkling liquid. The cork (10) is initially inserted into a neck (11) of the bottle (1) and retained by a muselet (12) tied under a ring (13) of a neck (14) of the bottle (1). The bottle opener includes retaining means (42) for forming an abutment against the ring (13), and allows free access to a loop of the muselet (12) for the untying thereof. The bottle opener includes damping means (6) for accompanying the cork (10) as it exits the neck (11) in an extraction direction (F) until a released position, in cooperation with the retaining means (42).
