Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for analyzing the contents of containers, such as X-ray examination, are inadequate as they cannot distinguish between organic materials and fail to identify hazardous liquid mixtures that can produce explosive or toxic substances when combined, especially when contained in opaque or colored bottles.
Innovation Solution
A device that emits and receives an electromagnetic field at various frequencies to measure the complex impedance of the container and its contents, combined with spectral analysis using infrared radiation between 1100 nm and 3 μm to determine the nature of the contents, and incorporates additional physical data like mass to improve reliability and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If X-ray examination is used to analyze container contents, then the examination method is simple and widely available, but it cannot distinguish between different organic materials and fails to identify hazardous liquid mixtures
Solution Approach 1:
The patent combines electromagnetic field measurement means and spectral analysis means into a single integrated device. The electromagnetic field means measure complex impedance to identify polar liquids, while the spectral analysis means use infrared radiation to detect molecular vibrations. Both measurement systems work together to provide comprehensive liquid identification, resolving the contradiction between detection accuracy and device complexity.
Solution Approach 2:
The patent measures complex impedance at multiple frequencies (at least two different frequencies) to detect changes in dielectric characteristics. By analyzing impedance parameters at different frequency points, the device can distinguish between different liquid compositions, including hazardous mixtures, thereby improving detection accuracy through parameter variation.
2Measurement precision
If spectral analysis device with lid is used to limit ambient light effects, then measurement accuracy is improved, but the device requires numerous manipulations and is not suitable for rapid repeated analyzes
Solution Approach 1:
The patent extracts the essential measurement function from complex manual operations. By using electromagnetic field means that measure complex impedance through the container walls, the system eliminates the need for manual lid opening/closing and container handling. The measurement is performed through the existing container structure, allowing rapid repeated analysis while maintaining precision through the electromagnetic measurement approach.
3Reliability
If electromagnetic field measurement is used to detect liquid composition, then the device can identify polar liquids, but it cannot reliably distinguish between authorized liquids and hazardous mixtures when contained in opaque or colored bottles
Solution Approach 1:
The patent employs a multi-functional measurement approach where the electromagnetic field means measure complex impedance to identify polar liquids, and the spectral analysis means use infrared radiation to detect molecular vibrations. This universal measurement system works through various container materials (transparent, opaque, colored) to provide reliable liquid identification, overcoming the limitation of single-method detection.
Solution Approach 2:
The patent uses electromagnetic fields and infrared radiation as intermediaries that can penetrate container walls to reach the liquid contents. These electromagnetic intermediaries transmit information about the liquid composition without requiring direct contact or visual access, enabling reliable detection through opaque and colored containers.
4Measurement precision
If additional physical data like mass is obtained to improve analysis reliability, then the accuracy of determining content nature is improved, but the device complexity increases
Solution Approach 1:
The patent integrates mass measurement capability into the existing support means for the container. The support means not only holds the container during electromagnetic and spectral analysis but also measures the mass of the container with contents. This merging of functions provides additional physical data for improved identification precision without significantly increasing overall device complexity.

AI summary
The device has a measuring unit for measuring complex impedance of a transmitter/receiver unit influenced by load constituted by a container i.e. bottle, and contents i.e. liquid. A spectral analysis unit measures wave absorptions by the container and contents. An information providing unit provides information relative to nature of contents of the container as a function of complex measured impedance and absorption measurement. The analysis unit sends waves with wavelengths in an infrared spectrum and measures absorption of the waves by the container and contents.
