Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If standard laboratory methods are used for frying oil characterization, then measurement precision is improved, but time consumption and operational complexity increase significantly

Engineering Contradiction:
Improveoil quality characterization accuracyVSAvoidtesting time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces complex mechanical/chemical laboratory analysis systems with optical measurement systems. Specifically, it uses optical sensors and spectrophotometric methods to measure oil quality parameters, substituting the need for time-consuming chemical tests and laboratory equipment with rapid optical detection that provides real-time or near-real-time results without requiring complex sample preparation or skilled laboratory staff.

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

Solution Approach 2:

The patent changes the measurement parameter from chemical composition analysis to optical property measurement. By monitoring changes in optical properties (absorbance, reflectance, transmittance) of the frying oil, the system能够快速 detect oil degradation without performing time-consuming chemical analyses, thus maintaining measurement precision while dramatically reducing testing time.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If chemical test methods are used for frying oil monitoring, then measurement precision is improved, but safety hazards increase due to handling hot oil

Engineering Contradiction:
Improveoil quality detection accuracyVSAvoidsafety hazards
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an optical intermediary (light) to measure oil quality without direct contact with hot oil. The optical sensor measures optical properties of the oil through a non-contact or minimal-contact method, using light as the intermediary carrier to transfer information about oil quality without requiring the operator to handle hot oil, thus eliminating safety hazards while maintaining measurement precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces mechanical sampling and chemical testing procedures with optical measurement systems. Instead of physically taking oil samples and performing chemical tests that require handling hot oil, the system uses optical sensors to measure oil quality parameters remotely or through minimal contact, substituting the hazardous mechanical/chemical process with a safe optical detection method.

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

3Ease of operation

If visual inspection methods are used for oil quality assessment, then ease of operation is improved, but measurement precision deteriorates due to subjectivity

Engineering Contradiction:
Improveoil quality assessment simplicityVSAvoidquality assessment accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent utilizes color changes in the frying oil as an objective indicator of degradation. By measuring optical properties such as absorbance, reflectance, or transmittance at specific wavelengths, the system quantifies color changes that occur during oil degradation. This provides an objective, numerical measurement rather than subjective visual assessment, thereby improving measurement precision while maintaining ease of operation through automated optical detection.

Inventive Principle:
Principle #32Color changes

4Productivity

If dielectric measurement instruments are used for oil monitoring, then productivity is improved, but device complexity and operational difficulty increase

Engineering Contradiction:
Improveoil testing efficiencyVSAvoidmeasurement instrument complexity
Core Design Contradiction:

Solution Approach 1:

The patent replaces complex dielectric measurement instruments with simpler optical measurement systems. Instead of using dielectric sensors that require calibration, heating to specific temperatures, and filtering procedures, the system employs optical sensors and spectrophotometric methods that are inherently simpler, require no special preparation, and provide direct measurements of oil quality parameters, thus maintaining productivity while reducing device complexity and operational difficulty.

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