Solution Overview

Problem

Existing beverage bottles that convert into glasses for direct consumption face issues with suboptimal tightness, difficult bottom removal, and hygiene concerns due to threaded contact surfaces.

Innovation Solution

A bottle design featuring a removable bottom with pressure-fitted shaped elements and a tightening collar for improved tightness, along with a metal counter-lid and elastic protruding elements that allow for secure and hygienic conversion into a glass, ensuring the lid is only removed before drinking to prevent foreign body contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the bottom is screwed onto the shaped body of the bottle, then the bottle can be converted into a glass for direct consumption, but the tightness of the bottle is not optimal

Engineering Contradiction:
Improveconversion into glassVSAvoidtightness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The bottom is divided into separate functional elements: a removable closure part with threaded connection for secure sealing, and a glass-forming part with elastic protruding elements. This segmentation allows the threaded portion to provide optimal tightness while the elastic elements enable easy removal and glass conversion.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The elastic protruding elements are nested within the bottom structure, allowing them to be compressed during screwing for secure tightness, then expand to engage with the lid for glass conversion. This nested design enables both optimal sealing and versatile transformation.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If the bottom is screwed onto the shaped body of the bottle, then the bottle can be converted into a glass, but the unscrewing operation is not simple

Engineering Contradiction:
Improveconversion into glassVSAvoidbottom removal
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The bottom is segmented into a closure portion with threaded connection and a glass-forming portion with elastic elements. This allows the user to apply force only to the elastic elements for removal, making the operation simple while maintaining secure threaded sealing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The elastic protruding elements provide dynamic engagement - they compress during screwing for tightness, then can be easily depressed for removal. This dynamic behavior simplifies the unscrewing operation while ensuring secure closure.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the threaded part of the bottle body is used as the glass bottom, then the bottle converts into a glass, but it is not hygienic as the threaded surface contacts the user's lips

Engineering Contradiction:
Improveconversion into glassVSAvoidhygiene
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The glass-forming surface is extracted from the threaded closure portion and placed in a separate bottom element with elastic protruding elements. This extraction ensures that only non-threaded, smooth surfaces contact the user's lips, maintaining hygiene while preserving the threaded connection for secure sealing.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The elastic protruding elements act as an intermediary between the threaded closure and the glass-forming surface. They provide a hygienic, smooth contact surface for the user's lips while the threaded portion remains isolated and dedicated to sealing functions only.

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
