Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor systems lack a method to effectively characterize the reliability and quality of measurement values, leading to uncertainties in measurement accuracy and potential failures due to varying signal-to-noise ratios and environmental changes.
Innovation Solution
A method and sensor system that generate and transmit primary measurement value signals along with coefficient signals, which characterize the reliability and quality of measurements, allowing for feedback loops to adjust the system and indicate when recalibration is needed, while maintaining compatibility with existing transmission protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor systems transmit only primary measurement value signals, then transmission protocol compatibility is maintained, but measurement reliability and quality characterization are insufficient
Solution Approach 1:
The patent combines primary measurement value signals with coefficient signals into a single transmitted signal package. The coefficient signals, which characterize measurement quality and reliability, are merged with the primary measurement data, allowing comprehensive measurement information to be transmitted together without requiring separate communication channels or protocols.
Solution Approach 2:
The patent introduces coefficient signals as intermediary elements that mediate between the raw measurement data and the evaluation system. These coefficient signals provide quality characterization information that helps the evaluation system assess measurement reliability without requiring complex additional verification procedures or changing the fundamental measurement transmission protocol.
2Reliability
If coefficient signals are added to characterize measurement quality, then measurement reliability improves, but data transmission volume increases
Solution Approach 1:
The patent applies local quality by adding coefficient signals that provide quality characterization specifically for each measurement value or measurement package. Rather than transmitting redundant full measurement data or using complex error correction codes, the coefficient signals provide targeted quality information locally associated with each measurement, enabling efficient data transmission with enhanced reliability assessment.
3Measurement precision
If feedback loops are implemented to adjust the system based on measurement quality, then measurement accuracy improves, but system complexity increases
Solution Approach 1:
The patent implements feedback loops that use coefficient signals to characterize measurement quality and reliability. The evaluation system receives both primary measurement values and coefficient signals, and uses the coefficient information to determine when recalibration is needed or when measurements should be rejected. This feedback mechanism improves measurement accuracy by enabling real-time quality assessment without requiring complex additional sensing hardware.
