Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the magnetic field sensor is designed to be non-removable and fixed in a specific location, then the installation and structural simplicity are improved, but the versatility and adaptability to different environments and applications deteriorates
Solution Approach 1:
The patent implements dynamics by enabling the magnetic field sensor to adapt its calibration parameters dynamically based on detected environmental characteristics. The sensor transitions from a static, fixed calibration to a dynamic, environment-dependent calibration system that automatically adjusts to different applications and locations.
Solution Approach 2:
The patent applies parameter changes by modifying the calibration parameters of the magnetic field sensor according to the detected environment. Different calibration parameter sets are selected and applied based on environmental detection results, allowing the same hardware to function accurately in multiple different contexts.
2Measurement precision
If the magnetic field sensor uses fixed pre-calibration data for a specific environment, then the measurement precision in that environment is improved, but the adaptability to different environments and applications deteriorates
Solution Approach 1:
The system dynamically switches between different calibration parameter sets based on the detected environment. Instead of using a single fixed calibration, the sensor adapts its calibration parameters in real-time according to the environmental context, maintaining precision across multiple applications.
Solution Approach 2:
The patent implements feedback by using the environment detector to continuously monitor the operational environment and feed this information back to the processor, which then selects the appropriate calibration parameter set. This closed-loop feedback ensures the sensor maintains accuracy by adapting to environmental changes.
3Ease of manufacture
If the magnetic field sensor requires pre-calibration data from external sources, then the initial setup and configuration are simplified, but the independence and self-supporting capability deteriorates
Solution Approach 1:
The patent applies self-service by enabling the magnetic field sensor to perform its own calibration automatically based on environment detection. The sensor no longer requires external pre-calibration data or manual configuration, as it independently detects the environment and selects appropriate calibration parameters autonomously.
