Vacuum Bottle Cap Structure for Beverage Freshness Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle covers lack an effective mechanism for evacuating air from beverage containers, which is crucial for maintaining the freshness of beverages like juice, soup, or tea, as most containers do not incorporate a pumping function for this purpose.
Innovation Solution
A bottle cover design featuring a bottom member, a sleeve, a top member, a hollow base, and an elastic component, where the sleeve is movable toward the hollow base, allowing air to be evacuated through a sealing mechanism that includes a first sealing component with a buckle and cover component, enabling air to pass through a second hole, and a locking mechanism to secure the cover tightly on the bottle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pumping mechanism is added to the bottle cover, then the ability to evacuate air from the bottle is improved, but the device complexity increases
Solution Approach 1:
The patent combines the pumping mechanism with the bottle cover structure, integrating the evacuation function into the cap assembly. The piston, sealing components, and spring are merged within the cap's hollow structure, creating a multi-functional unit that both seals the bottle and evacuates air, thereby improving reliability without proportionally increasing overall device complexity
Solution Approach 2:
The patent employs a nested structure where the piston is housed within the hollow base, which is integrated into the bottle cover. The sealing components are nested between the piston and the bottle opening, creating a compact arrangement that maximizes functionality within limited space, resolving the contradiction between evacuation capability and structural complexity
2Reliability
If a sealing mechanism is implemented to maintain negative pressure, then the freshness preservation is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent uses a dynamic sealing mechanism where the piston can move between positions. During opening, the piston moves to allow air ingress, automatically releasing the negative pressure seal. This dynamic behavior maintains freshness during storage while ensuring ease of operation during opening, as the user simply needs to break the seal rather than overcome vacuum pressure
Solution Approach 2:
The spring acts as an intermediary element that stores energy during the evacuation process and releases it during opening. The sealing components serve as intermediaries that control air flow, allowing the system to maintain negative pressure for freshness while providing a straightforward opening mechanism that doesn't require the user to directly combat vacuum forces
3Productivity
If the sleeve is made movable to enable pumping, then the air evacuation capability is improved, but the device complexity increases
Solution Approach 1:
The sleeve is designed as a movable component that can shift position during the pumping operation. This dynamic element works in conjunction with the piston to create the evacuation action, allowing air to be drawn out through the sealing mechanism. The movability is essential for productivity but adds to complexity, which is mitigated by the overall integration into the cap structure
Solution Approach 2:
The movable sleeve is merged with the piston assembly and sealing components, forming an integrated pumping mechanism. Rather than being a separate complex device, the sleeve's movement is coordinated with other elements within the cap, combining multiple functions into a unified structure that achieves effective air evacuation without proportionally increasing complexity
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 bottle cover effectively evacuates air from the bottle, creating a negative pressure environment that prolongs the freshness of beverages by preventing spoilage and ensuring easy opening after use.
Implementation Method 1
an elastic component having one end sleeved with the hollow base and the other end sleeved with the sleeve, the elastic component being compressed upon movement of the sleeve towards the hollow base
