Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual refilling of water tanks is used, then the machine can operate with simple structure, but frequent refilling is required which reduces productivity

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoidconnection system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces a connecting device as an intermediary component that bridges the beverage machine and the city water distribution network. This mediator includes a valve arrangement and control unit that automatically manages water supply, eliminating the need for frequent manual refilling while maintaining manageable system complexity through modular design

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The connecting device is designed to be universally applicable to various beverage machines with water tanks. It provides multiple functions including automatic water supply, overflow prevention, and easy installation/removal, making it a versatile solution that improves productivity across different machine types without requiring complex machine-specific modifications

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If direct connection to city water network is implemented, then continuous water supply is achieved, but overflow issues may occur

Engineering Contradiction:
Improvecontinuous water supplyVSAvoidoverflow risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The control unit receives feedback from level sensors that monitor the water level in the beverage machine's tank. When the tank reaches its maximum capacity, the sensor signals the control unit to close the valve arrangement, automatically preventing overflow while maintaining continuous supply capability from the city water network

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The valve arrangement is designed to be dynamically controllable, switching between open and closed states based on real-time tank level conditions. This dynamic control enables the system to adapt to varying water levels and prevent overflow while maintaining efficient continuous water supply when the tank has capacity

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If valve arrangement with control unit is added, then automatic liquid supply and overflow prevention are achieved, but device complexity increases

Engineering Contradiction:
Improveautomatic operationVSAvoidcontrol system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control unit and valve arrangement form an automated self-service system that monitors tank levels and controls water supply without user intervention. The system automatically opens the valve when water is needed and closes it when the tank is full, providing ease of operation while keeping the control logic simple and manageable

Inventive Principle:
Principle #25Self-service

4Productivity

If connecting device is integrated into beverage machine, then continuous water supply is enabled, but retrofitting difficulty increases

Engineering Contradiction:
Improvecontinuous operationVSAvoidretrofitting ease
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The connecting device is segmented into a separate, modular unit that can be independently installed on existing beverage machines. This segmentation allows the device to be retrofitted without modifying the machine's core structure, maintaining ease of manufacture and installation while enabling continuous water supply functionality

Inventive Principle:
Principle #1Segmentation
