Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional bottles with narrow openings make it difficult to refill and clean, especially around the shoulder area, and existing removable bases often trap condensation or liquid between the base and the bottle.

Innovation Solution

A bottle design with two openings, one at the top and one at the bottom, featuring a removable base that fits snugly over the wider bottom opening, using flexible materials and various attachment mechanisms to secure the base, and includes features to prevent condensation or liquid pooling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a narrow opening is used at the top of the bottle, then liquid can be poured precisely and reliably, but it becomes difficult to refill and clean the inside of the bottle

Engineering Contradiction:

Improvepouring precisionVSAvoidcleaning ease

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The bottle is divided into two functional openings: a narrow top opening for precise pouring and a wide bottom opening for easy refilling and cleaning. This segmentation allows each opening to optimize its specific function without compromise.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of having the functional opening at the top, the invention places a functional opening at the bottom of the bottle. This inversion allows the bottom opening to serve as the access point for refilling and cleaning, while the top opening maintains its pouring function.

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of operation

If a removable base is added to enable refilling and cleaning, then access to the bottle interior is improved, but condensation or liquid becomes trapped in the gap between the base and the bottle

Engineering Contradiction:

Improvecleaning accessVSAvoidliquid trapping

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The problematic gap between the removable base and bottle body is eliminated by integrating the base as a permanent, flush-mounted component. This extraction of the gap removes the space where liquid could become trapped.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The design proactively prevents liquid trapping by creating a flush surface between the base and bottle body, eliminating the gap before liquid can enter and become trapped. This preliminary design choice prevents the harmful effect rather than addressing it after occurrence.

Inventive Principle:

Principle #9Preliminary anti-action

3Strength

If the bottle uses conventional thick glass walls for durability, then strength is improved, but impact between bottles in a bar well increases and sound dampening is reduced

Engineering Contradiction:

Improveglass wall strengthVSAvoidimpact and sound

Core Design Contradiction:

StrengthVSObject-generated harmful factors

Solution Approach 1:

The bottle utilizes a removable base design that allows for thinner glass walls while maintaining structural integrity. The base acts as a flexible element that can absorb impact, reducing the need for excessively thick glass walls and thereby reducing impact and sound between bottles.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

The present application relates to a bottle comprising a reservoir, a first opening on a first end of the bottle providing access to the reservoir, a second opening on a second end of the bottle providing access to the reservoir; and a removable base covering the second opening.
