Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses and methods struggle to determine additional parameters of analytes in a liquid, particularly when the analytes are optically similar, making it difficult to distinguish and quantify them accurately.
Innovation Solution
An apparatus with a translucent porous element and a light-based system is used to measure time response values of analytes in a liquid, allowing for the determination of parameters such as molecular weight, shape, and viscosity by diffusing analytes through dead-end pores without external energy, and combining this with optical measurements to derive additional information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional apparatuses are used to measure analytes, then basic detection is possible, but additional parameters such as time response values cannot be determined
Solution Approach 1:
The patent combines optical detection with temporal resolution capabilities in a single measurement system. The apparatus integrates a light source, porous element, and detector to simultaneously capture both optical properties and time response data, eliminating the need for separate measurement systems and thereby obtaining additional parameters without proportionally increasing device complexity
Solution Approach 2:
The patent introduces dynamic temporal resolution to a traditionally static optical measurement system. By capturing light transmission data at multiple time points during the diffusion process, the system transforms from a single-point optical measurement to a dynamic, time-resolved measurement capability, enabling determination of time response values and diffusion characteristics
2Measurement precision
If optical measurements are used to detect analytes, then concentration can be determined, but analytes with similar optical properties cannot be distinguished
Solution Approach 1:
The patent introduces time response as an additional differentiation parameter beyond optical properties. By measuring the temporal profile of light transmission during diffusion, the system can distinguish analytes based on their unique diffusion rates and time response characteristics, even when their optical absorption spectra are similar or identical
Solution Approach 2:
The patent adds the temporal dimension to optical measurement data. Instead of relying solely on spatial/optical parameters for analyte identification, the system incorporates time-resolved data, creating a two-dimensional parameter space (optical + temporal) that enables differentiation of analytes that would be indistinguishable in one dimension alone
3Measurement precision
If diffusion through porous elements is used, then analytes can be separated by size, but larger particles may enter the pores
Solution Approach 1:
The patent employs porous elements with spatially varying pore sizes and optimized local structures. The porous medium is designed with specific pore diameter distributions and geometries that create a size-selective barrier, allowing small analyte molecules to diffuse into the pores while preventing larger particles from entering, thereby achieving both separation and protection

Data Source
AI summary
An apparatus that determines time response values of at least one analyte in a liquid includes a translucent element having dead end pores extending into the translucent element from respective openings in the translucent element. A cross-sectional dimension of the openings is dimensioned to prevent larger particles or debris from entering the pores while allowing the analyte(s) in the liquid to enter the pores via diffusion. One or more light sources illuminates the pores. A light detector receives light emerging from the pores in response to illumination by the one or more light sources. The light detector generates one or more signals based on the received light. Each signal is temporally resolved and representative of at least a part of the received light. The apparatus further includes a data processing device having a processor that determines one or more time response values based on the one or more signals.
