Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refractometers with fixed temperature trays require multiple scales for different temperatures, leading to inaccurate concentration measurements when temperature changes, while ambient tray refractometers use approximations that are limited by data points and memory constraints, failing to provide precise concentration readings across varying temperatures and concentrations.
Innovation Solution
A universal refractometer system employing a 3D polynomial scale that correlates refractive index, concentration, and temperature on a single scale, using a single advanced polynomial equation to accurately determine concentrations over a range of temperatures and concentrations, replacing the need for multiple scales.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple scales are used for different temperatures in fixed temperature tray refractometers, then measurement accuracy for specific temperatures is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The patent implements a single universal scale that can accurately measure concentration across multiple temperature ranges (e.g., -20°C to 40°C) without requiring separate scales for different temperatures. This universal scale incorporates temperature compensation data, allowing one scale to replace multiple temperature-specific scales, thereby reducing device complexity while maintaining measurement accuracy.
Solution Approach 2:
The patent uses temperature compensation technology to adjust measurement parameters dynamically based on temperature changes. By incorporating temperature data into the measurement system and using algorithms that compensate for temperature effects, the system maintains accurate concentration readings across varying temperatures without requiring multiple physical scales.
2Device complexity
If ambient tray refractometers use approximation methods with limited data points, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent employs advanced temperature compensation algorithms that dynamically adjust measurement parameters based on real-time temperature data. These algorithms use comprehensive calibration data and mathematical models to calculate accurate concentration values across wide temperature ranges, achieving high precision without requiring extensive stored lookup tables or complex data structures.
Solution Approach 2:
The patent replaces traditional mechanical scale adjustments with electronic temperature compensation calculations. Instead of using physical scales that must be manually selected or switched, the system uses electronic sensors and computational algorithms to automatically compensate for temperature effects, reducing the need for extensive stored data while maintaining high measurement precision.
3Reliability
If fixed temperature tray refractometers use multiple scales, then accuracy at fixed temperatures is maintained, but adaptability to varying temperatures is reduced
Solution Approach 1:
The patent designs a universal measurement system that can accurately measure concentration across a wide temperature range (-20°C to 40°C) using a single scale. This universal scale incorporates temperature compensation capabilities, allowing the system to adapt to varying temperatures while maintaining the reliability of fixed-temperature measurements, thereby eliminating the trade-off between fixed-temperature accuracy and temperature flexibility.

AI summary
A portable liquid design system includes a portable information handling system (IHS) that employs a liquid design application capable of operating in different modes to design different liquids such as corn syrup, espresso, coffee, soda pop and others. The portable liquid design system may include a refractometer to measure the refractive index and temperature of a liquid under test. The liquid design application may apply the measured refractive index and temperature to a 3 dimensional representation of the correlation of refractive index, temperature and concentration (% total dissolved solids) to determine a particular concentration corresponding to the measured refractive index and temperature. A single 3 dimensional scale may apply to virtually all values of interest of refractive index, temperature and concentration for a particular liquid under test.
