Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple temperature sensors are used to measure temperatures of multiple burners simultaneously, then measurement precision is improved, but device complexity and cost increase

Engineering Contradiction:

Improvetemperature measurement accuracyVSAvoidnumber of temperature sensors

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

A single temperature sensor is designed to perform multiple measurement functions by sequentially measuring temperatures of different burners at different time points. The sensor serves as a universal measuring device that can measure any burner's temperature through positional adjustment, eliminating the need for dedicated sensors for each burner.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The temperature sensor is made movable rather than fixed, allowing it to dynamically adjust its position to face different burners. This dynamic positioning capability enables one sensor to replace multiple fixed sensors, reducing overall system complexity while maintaining measurement precision.

Inventive Principle:

Principle #15Dynamics

2Device complexity

If a single temperature sensor is used to measure multiple burners, then device complexity is reduced, but measurement precision deteriorates due to sequential rather than simultaneous measurement

Engineering Contradiction:

Improvenumber of temperature sensorsVSAvoidtemperature measurement accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The system implements periodic measurement cycles where the single temperature sensor sequentially measures each burner in turn. This periodic action allows the sensor to capture temperature data from multiple burners over time, achieving comprehensive monitoring without requiring simultaneous measurement capabilities.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system uses feedback mechanisms to determine which burner needs measurement next based on operational status. The control unit receives feedback about burner operation states and directs the temperature sensor to measure the appropriate burner, ensuring accurate temperature monitoring is maintained despite sequential measurement.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If the temperature sensor is made movable to adjust sensing direction, then adaptability is improved, but device complexity increases due to adding driving mechanisms

Engineering Contradiction:

Solution Approach 1:

The patent replaces complex mechanical positioning systems with electromagnetic actuation. The driving device uses electromagnetic fields to control the temperature sensor's orientation, eliminating the need for complex mechanical gears, linkages, and manual adjustment mechanisms while achieving precise directional control.
