Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Analog sensors, such as Hall sensors and sliding rheostats, suffer from output value errors due to individual differences and installation position variations, leading to limited sampling ranges that affect user control accuracy and experience.
Innovation Solution
A dynamic sampling method that sets a preset sampling range, compares the analog sample value with the actual sampling range, and adjusts the range dynamically to ensure all values within the actual output range are collected, adapting to different applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed sampling range is set to account for sensor errors, then reliability is improved, but measurement precision deteriorates
Solution Approach 1:
The patent implements dynamic sampling range adjustment by continuously monitoring sensor output values and automatically expanding or contracting the sampling range based on actual sensor performance. This transforms the static fixed range into a dynamic adaptive range that maintains reliability while preserving measurement precision across different sensor individualities.
Solution Approach 2:
The system establishes a feedback mechanism where sensor output values are continuously monitored and fed back to adjust the sampling range. This feedback loop enables the system to learn from actual sensor behavior and automatically optimize the sampling range, resolving the contradiction between maintaining reliability and preserving measurement precision.
2Reliability
If a fixed sampling range is set to account for sensor errors, then reliability is improved, but adaptability deteriorates
Solution Approach 1:
The patent transforms the static fixed sampling range into a dynamic adaptive range that automatically adjusts to different sensor individualities and installation conditions. This dynamic adjustment mechanism enables the system to adapt to various sensor characteristics while maintaining reliable operation, thus resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The system changes the sampling range parameter dynamically based on actual sensor output values. By adjusting this key parameter adaptively, the system maintains reliability across different sensor individualities while improving adaptability to various sensor characteristics and installation conditions.
3Reliability
If a fixed sampling range is set to account for sensor errors, then reliability is improved, but device complexity deteriorates
Solution Approach 1:
The patent implements a self-service mechanism where the system automatically adjusts its own sampling range based on sensor output values without requiring external intervention or complex configuration. This self-adjusting capability maintains reliability while minimizing the increase in device complexity by using simple automatic adjustment logic.
Solution Approach 2:
The feedback mechanism monitors sensor outputs and automatically adjusts the sampling range without requiring complex external control systems. This simple feedback-based approach maintains reliability while keeping device complexity manageable through automatic self-regulation.

AI summary
A dynamic sampling method for an analog sensor and devices thereof are disclosed. The method includes reading a preset sampling range, taking a minimum value of the preset sampling range as a minimum value of an actual sampling range, and taking a maximum value of the preset sampling range as a maximum value of the actual sampling range; sampling an output of the analog sensor to obtain an analog sample value; outputting an actual sample value according to a comparison result between the analog sample value and the actual sampling range; and adjusting the actual sampling range according to the comparison result between the analog sample value and the actual sampling range. The dynamic sampling method realizes a dynamic adjustment of the actual sampling range of the analog sensor. When the analog sample value exceeds the preset sampling range, the actual sampling range is timely and dynamically updated.
