Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a temperature sensor is mounted on the board to measure shutter temperature, then the measurement process becomes feasible, but the measurement precision deteriorates due to temperature difference between board and shutter

Engineering Contradiction:

Improvefeasibility of temperature measurementVSAvoidtemperature measurement precision

Core Design Contradiction:

Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent introduces a shutter temperature compensation value as an intermediary parameter to bridge the temperature difference between the board (where the sensor is mounted) and the shutter (the actual component being measured). This compensation value is obtained through calibration measurements and is used to correct the board temperature reading, thereby resolving the contradiction between feasibility and precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the parameter used for temperature measurement from the raw board temperature reading to a corrected shutter temperature that incorporates the compensation value. By transforming the measurement parameter to account for the temperature discrepancy, the system achieves both feasibility (using board sensor) and precision (corrected temperature).

Solution Approach 1:

The patent employs feedback mechanisms through calibration processes where the system measures temperature at known reference conditions to determine compensation values. These feedback-derived compensation values are then applied to correct subsequent measurements, enabling continuous operation while maintaining precision despite noise interference.

Inventive Principle:

Solution Approach 2:

The patent converts the harmful effect of noise and temperature discrepancies into beneficial correction data through calibration measurements. By measuring temperature differences under controlled conditions and using these to derive compensation values, the system transforms what would be measurement errors into corrective factors that improve overall measurement precision.
