Solution Overview

Problem

Conventional bottles with narrow openings make it difficult to refill and clean, especially 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 with a larger diameter than the bottle, includes a removable cap covering the first opening and a removable base, and a removable base, which facilitates easy cleaning and prevents internal lips or ridges within the reservoir, and a tapering internal taper, and a tapering internal diameter from the shoulder to the second opening, along with a flexible material for the base to prevent condensation and impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a narrow opening is used at the top of the bottle, then pouring precision is improved, but cleaning difficulty increases

Engineering Contradiction:
Improvepouring precisionVSAvoidcleaning difficulty
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 cleaning and refilling. 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 large functional opening at the bottom of the bottle. This inversion solves the cleaning difficulty problem while maintaining the narrow top opening for pouring precision.

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of operation

If a removable base is added to the bottle, then cleaning ease is improved, but liquid trapping increases

Engineering Contradiction:
Improvecleaning easeVSAvoidliquid trapping
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The removable base is designed to sit substantially flush with the bottom exterior surface of the bottle, creating an equipotential surface that prevents liquid accumulation in gaps or recesses, thereby eliminating the liquid trapping problem.

Inventive Principle:
Principle #12Equipotentiality

Solution Approach 2:

The removable base incorporates a tapered internal diameter that matches the bottle's shoulder taper, creating a smooth transition surface that prevents liquid buildup at the interface between the base and bottle.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If a removable base with larger diameter than bottle is used, then cleaning access is improved, but structural stability worsens

Engineering Contradiction:
Improvecleaning accessVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The removable base features a tapered internal diameter that locally matches the bottle's shoulder geometry, creating a precise fit that enhances structural stability while maintaining overall larger diameter for cleaning access.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The tapered curved surface of the removable base complements the bottle's shoulder curvature, creating a smooth transitional interface that distributes mechanical stresses evenly and maintains structural integrity.

Inventive Principle:
Principle #14Spheroidality (Curvature)
