Solution Overview

Problem

Vending machines for beverages face challenges in accurately dosing ingredients, especially for items like tea leaves or coffee beans, due to the need for pre-programmed preparation parameters that do not account for user preferences or ingredient properties, leading to inefficiencies and potential errors in drink preparation.

Innovation Solution

A measuring vessel with a weighing module and communication module that allows for wireless communication with the vending machine, enabling the recording and transmission of weight information and user preferences, which adapts preparation parameters for customized drink preparation without the need for direct storage of ingredients within the machine.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If pre-programmed preparation parameters are used in vending machines, then drink preparation can be automated, but user preferences and ingredient properties cannot be accounted for

Engineering Contradiction:
Improvedrink preparation automationVSAvoidadaptation to user preferences and ingredient properties
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The patent implements feedback mechanisms where the system records user preferences and ingredient properties, then uses this information to automatically adjust preparation parameters. The weighing module provides feedback on ingredient weight, and this data is stored and used to customize future drink preparations without requiring manual re-programming.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables self-service by automatically adapting to user preferences and ingredient characteristics without requiring manual intervention. The machine learns from user choices and ingredient weights to autonomously optimize preparation parameters for subsequent drinks.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If ingredients are stored directly in the drinks machine, then preparation can be simplified, but storage space requirements increase

Engineering Contradiction:
Improvepreparation simplificationVSAvoidstorage space in drinks machine
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The patent extracts the ingredient storage function from the drinks machine itself. Ingredients are stored externally in separate containers and brought to the machine only when needed for preparation. This eliminates the need for large built-in storage compartments while maintaining operational simplicity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary measuring vessel that serves as a bridge between external ingredient storage and the drinks machine. This mediator allows ingredients to be transferred efficiently without requiring the machine to have its own large storage capacity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If manual input of preparation parameters is required, then customization is possible, but time consumption and error probability increase

Engineering Contradiction:
Improvepreparation parameter customizationVSAvoidtime for parameter input
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by pre-recording user preferences and ingredient properties in a database. When a drink is prepared, the system automatically retrieves and applies the appropriate parameters without requiring manual input, thus eliminating time loss while maintaining full customization capability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system performs self-service by automatically selecting and applying preparation parameters based on stored user preferences and ingredient characteristics, eliminating the need for manual parameter entry while maintaining customization.

Inventive Principle:
Principle #25Self-service

4Adaptability or versatility

If multiple measuring markings are provided on measuring vessels, then different substances can be measured, but the device complexity increases

Engineering Contradiction:
Improvemeasurement capability for different substancesVSAvoidmeasuring vessel complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical system of multiple physical markings on measuring vessels with an electronic measurement system. The weighing module electronically determines the correct amount of each ingredient based on its weight, eliminating the need for multiple visual markings while maintaining versatility for measuring different substances.

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

Solution Approach 2:

The system changes the measurement parameter from visual volume markings to electronic weight measurement. This allows a single measuring vessel to accurately measure different ingredients with varying densities by using weight as the universal measurement parameter instead of volume markings tailored to specific substances.

Inventive Principle:
Principle #35Parameter changes

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

This solution simplifies and enhances the accuracy of ingredient dosing, reduces storage requirements in vending machines, and allows for personalized beverage preparation based on user preferences and ingredient properties, improving user satisfaction and operational efficiency.

Implementation Method 1

The quantity of ingredients positioned in the measurement volume has a weight that causes the scale module to deform or deflect.

Methodology Applied
Scientific EffectDeformation: Deformation

Implementation Method 2

When the weighing module is placed in the measuring volume, the deformation can occur due to a change in pressure corresponding to the weight of the ingredients.

Methodology Applied
Scientific EffectPressure: Pressure Increase
