Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If spectrometry is used to measure flowing liquid in a pipeline, then measurement simplicity and speed are improved, but measurement precision deteriorates due to impurities attachment and bubbles

Engineering Contradiction:

Improvemeasurement speedVSAvoidoptical spectrum measurement accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The patent extracts and removes bubbles from the liquid sample using a centrifugal separation mechanism. The rotating valve cavity creates centrifugal force that separates bubbles from the liquid, extracting the harmful phase (gas bubbles) before measurement to improve optical spectrum accuracy

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent performs preliminary actions by rotating the liquid in the valve cavity before measurement to achieve two purposes: (1) centrifugal separation of bubbles from liquid, and (2) flushing of impurities from optical components. This preliminary treatment eliminates measurement errors before the actual spectrometry occurs

Inventive Principle:

Principle #10Preliminary action

2Difficulty of detecting and measuring

If light penetrates through the central area of the valve cavity, then detection sensitivity is improved, but measurement precision deteriorates due to bubble interference

Engineering Contradiction:

Improvedetection sensitivityVSAvoidoptical spectrum accuracy

Core Design Contradiction:

Difficulty of detecting and measuringVSMeasurement precision

Solution Approach 1:

The patent applies local quality by making different regions of the valve cavity serve different functions: the central area is designed for bubble discharge and light transmission, while the peripheral area handles liquid rotation and centrifugal separation. The light path is specifically positioned to pass through the central region where bubbles are removed, ensuring high detection sensitivity without bubble interference

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent converts the harmful effect of bubbles into a beneficial separation mechanism. By introducing rotation, bubbles are pushed to the center and concentrated, making them easier to remove. The centrifugal force that initially causes bubble movement is transformed into a useful separation tool that improves measurement accuracy

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Measurement precision

If liquid rotation is implemented to remove bubbles, then measurement precision is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies universality by designing the valve cavity to perform multiple functions simultaneously: (1) liquid rotation for bubble removal, (2) flushing of optical components, (3) sample holding, and (4) light transmission path provision. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving improved measurement precision
