Solution Overview

Problem

Existing drinkware containers lack effective temperature retention and controlled pouring mechanisms, particularly for hot or cold beverages, as they often rely on simple insulation and lack a secure, controlled spout system.

Innovation Solution

An insulating container with a double-wall vacuum construction and a spout adapter system that includes a magnetic cap and docking surface for secure sealing, along with a spout adapter that provides a narrower opening for controlled pouring, utilizing a combination of materials like steel, titanium, and polymers for enhanced thermal resistance and user-friendly handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple insulation structure is used, then the device complexity is reduced, but the temperature retention capability deteriorates

Engineering Contradiction:
Improveinsulation structureVSAvoidtemperature retention
Core Design Contradiction:
Device complexityVSTemperature

Solution Approach 1:

The patent implements a double-wall construction where an inner wall containing the beverage is nested within an outer wall, creating a vacuum-insulated chamber between them. This nested structure provides effective thermal insulation to maintain beverage temperature without requiring complex active cooling or heating systems.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent creates a vacuum environment (inert atmosphere free of heat-conducting molecules) in the space between the inner and outer walls. This vacuum layer acts as an excellent thermal insulator, preventing heat transfer between the beverage and external environment, thus maintaining temperature effectively.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

2Ease of operation

If a wide opening is used in the container, then the ease of operation for filling is improved, but the temperature retention capability deteriorates due to increased heat loss

Engineering Contradiction:
Improvefilling convenienceVSAvoidtemperature retention
Core Design Contradiction:
Ease of operationVSTemperature

Solution Approach 1:

The patent divides the opening into two functional segments: a wide mouth opening for easy filling and pouring, and a separate narrow spout opening for controlled dispensing. The spout adapter with its narrow aperture allows precise pouring while the wide mouth remains available for rapid filling, thus resolving the contradiction between ease of operation and temperature retention.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spout adapter acts as an intermediary component that provides a controlled narrow opening for pouring while maintaining the integrity of the vacuum insulation system. It mediates between the need for controlled dispensing and the requirement to minimize heat loss through openings.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If a magnetic coupling system is used, then the reliability of sealing is improved, but the device complexity increases

Engineering Contradiction:
Improvesealing securityVSAvoidcoupling mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical sealing mechanisms (such as threads, clips, or latches) with a magnetic coupling system. Magnets embedded in the spout adapter and corresponding magnetic elements in the cap create a secure seal through magnetic attraction, eliminating the need for complex mechanical fastening while improving sealing reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An insulating container can be configured to retain a volume of liquid, and include a canister having a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The opening can be sealed by a spout adapter, the spout adapter having a spout channel extending between the internal reservoir and a spout opening, smaller than the opening of the canister. The spout opening may be sealed with a cap having a magnetic top surface, and the spout adapter may be further removably coupled to a lid that may be used as a cup into which a volume of the liquid can be poured.
