Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional beverage bottles require opening and pouring into a glass for consumption, which is inconvenient and unhygienic, especially for small volumes or shared drinking, and necessitates glass washing, wasting manpower and resources.

Innovation Solution

A bottle design where the bottom is detachable and screwable, allowing the bottle to be used upright with the cap below, enabling direct drinking from the bottle neck while maintaining a secure seal until opening, and facilitating easy recycling of components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the bottle is opened and the beverage is poured into a glass for consumption, then the beverage can be consumed in a traditional manner, but the process becomes inconvenient and unhygienic, especially for small volumes or shared drinking, and necessitates glass washing

Engineering Contradiction:

Improveconvenience of beverage consumptionVSAvoidtime for glass washing

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent merges the bottle and glass functions into a single integrated structure. The bottle body is designed with an upwardly directed reception space that can contain a glass, and the bottom portion can be detached to serve as a stable base for drinking directly from the bottle or for placing a glass. This integration eliminates the need for separate glassware and washing processes.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The bottle is designed with multiple functions: it serves as a beverage container, a drinking vessel, and a stable base (when the bottom is detached). The reception space within the bottle body can accommodate a glass for traditional pouring, or the user can drink directly from the bottle neck or bottom opening. This multi-functionality eliminates the need for dedicated glassware.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If the bottle mouth is permanently closed with a cap, then the seal integrity and hygiene are maintained, but the bottle cannot be used in an inverted position safely

Engineering Contradiction:

Improveseal integrityVSAvoidpositioning flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The bottle is segmented into a removable bottom portion and a main body. The bottom portion can be detached to create an opening for inverted positioning, while the main body retains the permanently closed cap for maintaining seal integrity during normal storage and transport. This segmentation allows the bottle to adapt to different positioning requirements while preserving seal reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bottle transitions from a static, permanently closed structure to a dynamic configuration where the bottom portion can be removed. This allows the bottle to switch between a closed state (for maintaining seal integrity) and an open state (for inverted positioning or direct drinking), providing adaptability while preserving reliability when needed.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the bottom is made detachable and screwable, then the bottle can be used upright with the cap below and components can be recycled easily, but the structural complexity increases

Engineering Contradiction:

Improveusage position flexibilityVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bottle design inverts the traditional usage orientation by allowing the cap to be positioned at the bottom and the detachable bottom portion to be at the top, creating a stable upright position for drinking. This inversion enables the bottle to be used in non-traditional positions while maintaining structural simplicity through the use of a straightforward screw-threaded connection.

Inventive Principle:

Principle #13The other way round (Inversion)

4Ease of repair

If the bottom is detachable, then the components can be separated for recycling, but the manufacturing process becomes more complex

Engineering Contradiction:

ImproverecyclabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

Ease of repairVSEase of manufacture

Solution Approach 1:

The bottle is segmented into separable components (bottom portion and main body) connected by a screw-threaded interface. This segmentation enables easy separation for recycling purposes while using a standard, well-established manufacturing technique for the connection interface, minimizing the increase in manufacturing complexity.

Inventive Principle:

Principle #1Segmentation

AI summary

The invention regards a bottle, adapted in particular for containing beverages, which is characterised in that its bottom (4) is not integral with the, rest of the bottle, but is fixable to the aforesaid by means of reversible fixing means; in particular, said bottom can be screwed to the rest of the bottle. Once the bottle is rotated so that its bottom is turned upward, after having opened said bottom the bottle may be set, in opposite position to the normal positioning of the aforesaid bottle, atop this bottom (4), where there are present means of locking and clasping with the part normally arranged on the top part of the bottle and with the related cap, this permitting the user to drink the contents of the bottle by bringing his lips to that which normally composes the bottom of the aforesaid bottle, naturally once it is open.
