Solution Overview

Problem

Existing mixing vessels fail to effectively mix hot beverages, leading to a 'grainy' texture and rapid settling due to low shear forces, and pose safety risks with leakage when used for hot liquids.

Innovation Solution

A mixing vessel with a sealing member that transitions between two stable configurations, increasing volume to control pressure and prevent rapid depressurization, allowing for vigorous mixing and safe handling of hot beverages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If traditional stirring methods are used to mix hot beverages, then the mixing process is simple and safe, but the shear force is insufficient resulting in grainy texture and rapid settling

Engineering Contradiction:
Improveshear forceVSAvoidmixing operation
Core Design Contradiction:
ForceVSEase of operation

Solution Approach 1:

The lid is designed with a pressable button that transitions between extended and retracted states, enabling dynamic volume adjustment. When the button is pressed, the lid moves from an extended state (larger volume) to a retracted state (smaller volume), creating dynamic compression and expansion of the beverage to generate high shear forces for effective mixing.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mixing mechanism utilizes pneumatic pressure generated by compressing the beverage within the sealed container. Pressing the button reduces the internal volume, increasing pressure and forcing the beverage against the mixing element, thereby generating the necessary shear force without requiring manual stirring.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Reliability

If mixing is performed in a sealed container, then leakage is prevented, but pressure buildup may cause safety risks

Engineering Contradiction:
Improveleakage preventionVSAvoidpressure safety risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The lid incorporates a spring element that acts as a cushioning mechanism. When pressure builds up inside the sealed container during mixing, the spring compresses to absorb the excess pressure, preventing dangerous pressure buildup while maintaining the sealed environment for effective mixing.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The spring element undergoes elastic deformation (a mechanical phase transition) when compressed by internal pressure. This allows the system to transition from a high-pressure state to a balanced state, dissipating pressure safely while maintaining the seal integrity.

Inventive Principle:
Principle #36Phase transitions

3Volume of stationary object

If the container volume is increased to accommodate mixing, then more space is available for ingredients, but the container size becomes larger and less portable

Engineering Contradiction:
Improvecontainer volumeVSAvoidcontainer structure
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The lid's volume is dynamically adjustable through the pressable button mechanism. The lid transitions between an extended configuration (providing larger internal volume for mixing) and a retracted configuration (reducing overall container size for portability). This dynamic adjustment allows the same container to serve both mixing and travel functions effectively.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mixing mechanism is nested within the lid structure itself. The button, spring, and volume-adjustment components are integrated into the lid, allowing the mixing functionality to be contained within the existing container footprint without requiring additional external components or significantly increasing overall size.

Inventive Principle:
Principle #7Nested doll (Nesting)
