Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional bottle tests are used to determine gelation time, then the method is simple and widely adopted, but human error occurs and lack of uniform standard exists

Engineering Contradiction:

Improvesimplicity of methodVSAvoidaccuracy of gelation time determination

Core Design Contradiction:

Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent replaces manual visual observation and mechanical bottle inversion with an automated optical detection system. A bubble generator injects gas bubbles at a known position, and optical sensors automatically track bubble movement and position, eliminating human error in determining gelation time while maintaining operational simplicity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces gas bubbles as intermediary objects to indicate the gelation state. The bubbles serve as tracers that make the invisible gelation process visible and measurable, allowing precise determination of when the gel structure forms by observing bubble movement cessation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If manual observation methods are used, then device complexity is low, but reliability and consistency of measurement are poor

Engineering Contradiction:

Improvecomplexity of measurement systemVSAvoidconsistency of gelation time measurement

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent implements automated feedback through optical sensors that continuously monitor bubble position and provide real-time data to a control system. This feedback mechanism ensures consistent and reliable gelation time measurements by objectively detecting when bubble movement stops, eliminating variability in manual observations.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs self-measurement by automatically tracking bubble positions and determining gelation time without human intervention. The optical detection system and control algorithm work together to autonomously complete the measurement process, ensuring high reliability and reproducibility across different tests.

Inventive Principle:

Principle #25Self-service

3Quantity of substance

If bubbles are released continuously, then measurement coverage is complete, but difficulty in detecting when gelation occurs increases

Engineering Contradiction:

Improvenumber of bubbles releasedVSAvoiddifficulty of detecting gelation point

Core Design Contradiction:

Quantity of substanceVSDifficulty of detecting and measuring

Solution Approach 1:

The patent uses periodic bubble release at predetermined time intervals rather than continuous release. This periodic injection creates discrete, easily trackable bubbles whose positions can be clearly monitored over time, making it simpler to detect when gelation occurs by observing when bubbles no longer reach expected positions.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent segments the measurement process by releasing bubbles at discrete time intervals and tracking each bubble's position separately. This segmentation transforms the continuous gelation process into discrete measurable events, making it easier to identify the precise moment when gelation begins by comparing bubble positions across different time points.

Inventive Principle:

Principle #1Segmentation

AI summary

A method and a system to determine a gelation time of a substance in a container is disclosed. The system includes a container, a bubble generator arranged at a first end of the container, and a bubble sensor arranged at the second end of the container. The container holds a substance having a surface adjacent the second end. The bubble generator is configured to generate a bubble at the first end. The bubble sensor is configured to sense the bubble at the surface of the substance. The method includes releasing a gas into a first end of the container such that the gas bubbles rise from the first end of the container to a second end of the container, sensing the released bubbles, determining an absence of a bubble released by the bubble generator at the bubble sensor, and determining a gelation time based on a number of detected bubbles.
