Cigar Moisture Meter Relative Humidity Conversion Circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cigar moisture meters provide readings of moisture content rather than relative humidity, which is the parameter cigar smokers are accustomed to, and lack the capability to display relative humidity levels inside the cigar.
Innovation Solution
A cigar moisture meter with electrical probes connected to a circuit that converts resistance readings into relative humidity values using a preinstalled table and microprocessor, displaying the results on a digital screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing moisture meters display moisture content instead of relative humidity, then the device complexity is reduced, but the ease of operation deteriorates because users cannot obtain direct relative humidity readings
Solution Approach 1:
The patent transforms the displayed parameter from moisture content to relative humidity by incorporating a lookup table that converts resistance measurements into relative humidity values based on pre-stored data corresponding to different temperature and moisture content conditions
Solution Approach 2:
The patent introduces a microprocessor and lookup table as intermediary components that automatically perform the conversion from moisture content to relative humidity, eliminating the need for manual calculation while maintaining device simplicity
2Loss of information
If existing moisture meters provide only moisture content readings, then the device complexity is reduced, but the loss of information increases because users cannot obtain relative humidity data
Solution Approach 1:
The patent changes the information parameter from moisture content to relative humidity by using a lookup table that stores pre-calculated relative humidity values corresponding to various moisture content and temperature combinations, enabling direct display of the desired parameter
Solution Approach 2:
The patent performs preliminary calculations by pre-computing and storing relative humidity values in a lookup table during manufacturing, so that during operation the microprocessor only needs to retrieve and display the pre-calculated value corresponding to the measured conditions

AI summary
A meter includes prongs that detect the moisture content value of a tobacco product, and an electrical circuit of the meter receives this information and converts the moisture content value to a relative humidity value of the tobacco product. The relative humidity value is displayed as a numeral on a display sensor connected to the electrical circuit.
