Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a manual densimeter method is used for measuring sugar and alcohol content, then the cost is low and implementation is simple, but the measurement cannot be automated and is sensitive to gas presence in the liquid

Engineering Contradiction:
Improveimplementation simplicityVSAvoidmeasurement automation
Core Design Contradiction:
Ease of manufactureVSExtent of automation

Solution Approach 1:

The patent replaces the manual mechanical densimeter with an electronic measurement system using pressure sensors and level detectors to automatically measure liquid density. The pressure sensor measures pressure at the bottom of the column, while the level detector measures liquid height, enabling automated calculation of density without manual intervention.

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

Solution Approach 2:

The system performs self-measurement by automatically drawing liquid samples through suction, measuring density parameters, and calculating results without requiring manual operation. The electronic device autonomously completes the entire measurement process from sampling to data output.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If a manual densimeter method is used, then the implementation is simple, but the measurement is sensitive to the presence of gas in the liquid

Engineering Contradiction:
Improveoperational simplicityVSAvoidmeasurement reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces the gas-sensitive mechanical densimeter with electronic pressure sensors that measure pressure independent of gas presence. Since pressure measurement at a fixed depth depends only on liquid density and height, not on gas bubbles, the measurement reliability is significantly improved while maintaining ease of operation.

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

3Ease of operation

If sampling is done through a valve on the tank front face, then the sampling process is simple, but the sample is not representative of the entire tank

Engineering Contradiction:
Improvesampling simplicityVSAvoidsample representativeness
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent uses hydraulic suction through a tube extending to the bottom of the tank to draw samples from the deepest layer where settled particles accumulate. This ensures the sample includes all components (liquid, suspended particles, and settled material) making it representative of the entire tank contents, while the automated suction process remains operationally simple.

Inventive Principle:
Principle #29Pneumatics and hydraulics

4Reliability

If CO2 level measurement is used for monitoring winemaking, then fermentation monitoring is possible, but the cost is high and careful sealing is required to avoid contamination

Engineering Contradiction:
Improvefermentation monitoring capabilityVSAvoidsealing requirement
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex sealed CO2 measurement systems with a simpler density measurement system. By measuring liquid density changes during fermentation (which naturally reflect CO2 production and sugar consumption), the system achieves reliable fermentation monitoring without requiring tight sealing or complex gas detection equipment.

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

AI summary

The apparatus (1) has a measuring device measuring density of liquid and comprising a measurement column (2), where the column is provided with a measurement pressure sensor. The sensor is placed at a column bottom. A determination unit determines height of the liquid in the measurement column. A top of the column is provided with a valve device containing anti-contamination liquid for neutralizing at the time of operation of draining of the column. The oxygen contained in outdoor air is aspired to avoid contamination of the liquid in a reinjected medium.
