Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users own multiple drinking vessels of different sizes and types, then various consumption needs are accommodated, but inconvenience and unnecessary duplication occur

Engineering Contradiction:

Improveversatility of drinking vesselVSAvoidnumber of vessels needed

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a single lid that can be used with both the first vessel and the second vessel. The lid is configured to fit the opening of the first vessel when nested within the second vessel, and also fit the opening of the second vessel when used separately. This multi-functionality resolves the contradiction by allowing one lid to serve multiple purposes, reducing the need for multiple specialized vessels while maintaining adaptability to different consumption needs

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent applies nesting by placing the first vessel inside the second vessel. The first vessel has a smaller capacity and is designed to nest within the larger second vessel. This nesting arrangement allows the system to function as a single unit when needed, reducing the apparent complexity of having multiple vessels, while still providing the versatility of different vessel sizes for different consumption scenarios

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If a single lid is designed to cover both nested and separate vessels, then versatility is improved, but lid design complexity increases

Engineering Contradiction:

Improveuniversal lid compatibilityVSAvoidlid design

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lid is designed with universal compatibility to fit both the first vessel opening and the second vessel opening. By making the lid dimensions and attachment mechanism suitable for both vessels, the patent achieves multi-functionality that resolves the contradiction between versatility and design complexity. The lid serves as a universal component that works across different vessel configurations

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The lid design incorporates adjustable or variable parameters that allow it to adapt to different vessel openings. This may include flexible sealing mechanisms, adjustable attachment features, or dimensional parameters that can accommodate both the smaller first vessel opening and the larger second vessel opening, thereby achieving universality without excessive complexity

Inventive Principle:

AI summary

Described herein are embodiments of a dual container drinking vessel with a universal lid. In one embodiment, the apparatus includes a first vessel and a second vessel, where the first vessel and the second vessel are at least partially nested together, and further includes a lid adapted to cover an open end of the first vessel when the first vessel and the second vessel are at least partially nested together, and to cover an open end of the second vessel when the first vessel and the second vessel are not nested together.
