Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If post-installation reference settings are used to verify device orientation, then device orientation can be verified, but manual adjustments are required which reduces operational efficiency

Engineering Contradiction:

Improveorientation verification accuracyVSAvoidinstallation efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The processor is pre-programmed with specification data indicating the correct orientation and location for attachment to the tank. This preliminary configuration enables automatic orientation verification without requiring post-installation manual reference settings or adjustments, thereby resolving the contradiction between measurement precision and installation efficiency

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The device automatically determines its own orientation by comparing accelerometer data with the pre-stored specification data. This self-service mechanism eliminates the need for manual orientation verification and adjustment by installers, simultaneously achieving accurate orientation verification and maintaining high installation efficiency

Inventive Principle:

Principle #25Self-service

2Reliability

If manual orientation adjustment is required after installation, then correct orientation can be achieved, but operational inefficiencies occur due to additional manual steps

Engineering Contradiction:

Improvecorrect installation assuranceVSAvoidinstallation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The processor continuously monitors accelerometer data and automatically compares it with the pre-programmed specification data to determine whether the device is correctly oriented. This feedback mechanism provides automatic verification of correct installation without requiring manual orientation adjustment, thereby ensuring reliability while maintaining ease of operation

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The manual mechanical adjustment process is replaced by an automated electronic system using accelerometer sensors and processor-based comparison logic. This substitution eliminates the need for manual orientation adjustment while ensuring correct installation, resolving the contradiction between reliability and ease of operation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If accelerometer continuously monitors orientation, then tampering detection is immediate, but energy consumption increases

Engineering Contradiction:

Improvetampering detection capabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The processor polls the accelerometer at periodic intervals rather than continuously, and only triggers alerts when orientation changes exceed predetermined thresholds. This periodic monitoring approach enables effective tampering detection while significantly reducing power consumption compared to continuous monitoring

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system monitors changes in acceleration parameters and triggers detection only when changes exceed specific thresholds indicating potential tampering. This parameter-based approach enables reliable tampering detection while minimizing energy consumption by avoiding continuous full-power operation of the sensor and processor

Inventive Principle:

Principle #35Parameter changes
