Solution Overview

Problem

Existing reusable containers can only hold a single beverage at a time, lacking the ability to retain multiple beverages or foods at different temperatures simultaneously and provide customizable mixing options.

Innovation Solution

A dual-chambered container with thermally isolated compartments and a user-controlled lid mechanism that allows for simultaneous storage and mixing of multiple beverages, enabling adjustable output percentages of each liquid.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single-chamber container is used, then the device complexity is low, but the versatility is limited to holding only one beverage at a time

Engineering Contradiction:
Improveability to hold multiple beverages simultaneouslyVSAvoidcontainer structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container body is divided into multiple separate chambers (first chamber and second chamber) that are thermally isolated from each other, allowing simultaneous storage of different beverages at different temperatures. This segmentation enables the container to hold multiple beverages independently while maintaining thermal integrity for each compartment.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple containers are used to hold different beverages, then the versatility is improved, but the bulk and portability deteriorate

Engineering Contradiction:
Improveability to store multiple beveragesVSAvoidoverall container size
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

Multiple beverage storage chambers are merged into a single integrated container body, allowing users to carry multiple beverages in one container rather than multiple separate containers. The chambers share a common structural framework and lid assembly, reducing overall bulk while maintaining the ability to store different beverages independently.

Inventive Principle:
Principle #5Merging (Combining)

3Temperature

If chambers are thermally isolated, then the temperature retention is improved, but the device complexity increases

Engineering Contradiction:
Improvetemperature retention of beveragesVSAvoidthermal isolation structure
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The thermal isolation function is extracted as a separate structural feature between chambers, with insulating walls positioned between the first and second chambers to prevent heat transfer. This allows each chamber to maintain its temperature independently while using a relatively simple insulating barrier approach rather than complex active thermal management systems.

Inventive Principle:
Principle #2Taking out (Extraction)

4Adaptability or versatility

If a fixed lid mechanism is used, then the device complexity is low, but the adaptability for customizable mixing is limited

Engineering Contradiction:
Improvecustomizable mixing optionsVSAvoidlid mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lid mechanism incorporates movable or adjustable components that allow dynamic control over beverage dispensing and mixing ratios. Users can adjust the lid configuration to control the output percentage of each liquid, transforming a static lid into a dynamic control interface for customizable mixing ratios.

Inventive Principle:
Principle #15Dynamics

AI summary

A container assembly for storing multiple liquids is disclosed. The container assembly comprises a container body having a first compartment and a second compartment. Each compartment comprises an upper end, an opening at the upper end, and a lower end. The container assembly further comprises an insulator provided between the first compartment and the second compartment configured to separate both compartments, thereby allowing the container body to store multiple liquids simultaneously. Further, the container assembly further comprises a rotatable lid detachably attached to the upper end of the container body configured to prevent and stop any leakage, wherein the rotatable lid is activated to set the amount of liquid to be dispensed from each compartment.
