Solution Overview

Problem

Existing self-righting container technologies are limited to specific dimensional ratios and are not applicable to general fluid-filled containers, failing to provide a universal solution for self-righting functionality.

Innovation Solution

A self-righting fluid container design featuring a flanged neck portion, a weighted base portion, and an intermediate tapered section, with the center of gravity positioned on the positive side of a critical line extending from the point where the container contacts the support surface, ensuring the container remains upright regardless of fluid level or tilt.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If specific dimensional ratios are used for self-righting containers, then self-righting functionality is achieved, but applicability to general fluid-filled containers is limited

Engineering Contradiction:
Improveapplicability to general fluid-filled containersVSAvoiddimensional ratio constraints
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent establishes universal design criteria for self-righting containers that apply to any fluid-filled container regardless of size or shape. By defining the critical line position relative to the container geometry (at the intersection of the base portion and tapered section) and specifying that the center of gravity must be on the positive side of this critical line, the invention creates a universal solution that works for diverse container types rather than requiring specific dimensional ratios for each case.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes the approach from fixed dimensional ratios to variable parameters that adapt to different container sizes. The key parameter is the position of the center of gravity relative to the critical line, which can be adjusted by modifying the weight distribution in the base portion. This allows the same self-righting principle to apply to containers of various dimensions by simply adjusting the weight parameter rather than redesigning the entire geometry.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If a weighted base portion is added to achieve self-righting, then stability is improved, but container weight increases

Engineering Contradiction:
Improveself-righting stabilityVSAvoidcontainer weight
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The patent uses a weighted base portion that acts as a counterweight to stabilize the container. The weight is strategically positioned in the base portion below the critical line, creating a restoring moment when the container is tilted. This counterweight approach provides the necessary stability for self-righting while concentrating the weight in a specific location rather than distributing it throughout the container.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

Solution Approach 2:

The patent addresses the weight issue by transitioning from considering only the vertical dimension to incorporating the horizontal dimension through the critical line concept. By positioning the center of gravity on the positive side of the critical line (which extends from the contact point through the intersection of base and tapered section), the invention creates a geometric relationship that ensures self-righting stability without requiring excessive weight, as the horizontal positioning relative to the critical line provides the restoring moment.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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 design effectively prevents spillage by maintaining the center of gravity on the positive side of the critical line, allowing the container to self-right and minimizing the required weight of the weighted member, thus reducing the risk of excessive weight and improving handling.

Implementation Method 1

The center of gravity of the container, whether filled or empty, is along the centerline of the container on the positive side of a critical line extending normal to the horizontal plane of the supporting surface

AI summary

A self righting fluid container having a flanged neck portion, a weighted base portion and an intermediate tapered section connecting the neck portion to the base portion. The center of gravity of the container, whether filled or empty, is along the centerline of the container on the positive side of a critical line which line extends normal to the horizontal plane of the support surface on which the container rests from a point where the container contacts the support surface and where the base portion intersects the tapered section.
