Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional material level indicators fail to detect environmental conditions and material properties in warehouses, which can lead to issues such as temperature-related explosions or spoilage, as they only measure material level without considering environmental factors like temperature and humidity.
Innovation Solution
A material level indicator comprising a probe with signal compensating units and a controlling module that uses electromagnetic signals to measure travel time differences to correct for environmental coefficients and detect dielectric coefficients of materials, incorporating signal boosters and weights to enhance signal intensity and reduce noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional material level indicators are used to measure material level only, then the device complexity is low, but the measurement precision is insufficient because environmental conditions and material properties cannot be detected
Solution Approach 1:
The material level indicator is designed to perform multiple functions: measuring material level, detecting environmental conditions (temperature, humidity), and analyzing material properties (dielectric coefficient). This multi-functional approach resolves the contradiction by enabling comprehensive detection without requiring separate devices, thus improving measurement precision while maintaining reasonable device complexity
Solution Approach 2:
The patent introduces signal compensating units as intermediaries to correct measurement errors caused by environmental factors. These compensating units serve as mediators between the electromagnetic signals and the measurement process, enabling accurate detection of material level and properties while accounting for environmental variations
2Measurement precision
If signal compensating units are added to correct environmental coefficients, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The signal compensating units are segmented into multiple independent components distributed along the probe. Each segment handles specific compensation tasks, allowing the system to achieve comprehensive environmental compensation while maintaining modular architecture that manages device complexity through distributed functionality
3Length of stationary object
If electromagnetic signals are transmitted through long distances in the probe, then the material level detection range is extended, but the signal intensity decreases and noise increases
Solution Approach 1:
Signal boosters are introduced as intermediary devices along the probe to amplify electromagnetic signals during transmission. These boosters act as mediators that compensate for signal attenuation over long distances, enabling extended detection range while maintaining signal quality and reducing noise impact
Solution Approach 2:
The patent ensures continuous signal transmission and amplification along the entire length of the probe through strategically placed signal boosters. This continuous action maintains signal integrity over extended distances, allowing long detection range without significant signal degradation or noise accumulation
