Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for monitoring analyte levels, such as creatinine, potassium, and sodium, in patients with kidney and cardiac conditions are invasive and do not provide real-time diet recommendations to manage these levels effectively.
Innovation Solution
A chemical sensing system using wearable and implantable devices with optical-based sensors that measure analyte levels in interstitial fluid or bodily fluids, providing real-time diet recommendations through a user interface based on threshold comparisons and historical data to adjust protein, potassium, or sodium intake.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If invasive methods are used to monitor analyte levels, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces invasive mechanical sampling methods with optical sensing technology. Chemical sensors detect analyte levels through optical property changes in interstitial fluid, eliminating the need for blood draws or tissue biopsies while maintaining measurement accuracy.
Solution Approach 2:
The patent introduces interstitial fluid as an intermediary medium between the body's analyte sources and the optical sensors. This fluid pathway allows non-invasive access to analytes that would otherwise require direct tissue or blood sampling.
2Productivity
If real-time monitoring is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent divides the monitoring system into separate functional modules: wearable optical sensors for analyte detection, mobile computing devices for data processing and threshold comparison, and user interface components for recommendation delivery. This segmentation allows each component to be optimized independently.
Solution Approach 2:
The system implements continuous feedback loops where analyte levels are monitored in real-time, compared against thresholds and historical data, and automatically trigger diet recommendations. This closed-loop feedback enables proactive health management without requiring complex manual intervention.
3Adaptability or versatility
If personalized recommendations are generated, then adaptability is improved, but loss of information increases
Solution Approach 1:
The system performs preliminary actions by establishing personalized thresholds and historical baseline data before acute health events occur. This pre-processing of information enables rapid, context-aware recommendations during critical moments without requiring complex real-time analysis.
Solution Approach 2:
The patent dynamically adjusts monitoring parameters and recommendation thresholds based on individual patient characteristics, health status, and historical responses. This adaptive parameter modification enables personalized care while managing information complexity through structured decision frameworks.

Data Source
AI summary
Systems, devices, and methods include approaches involving comparing an analyte level measured using a chemical sensor and based on an optical property to a threshold; determining that a creatinine level, a potassium level, or a sodium has reached the threshold; and generating a visual recommendation on a user interface to consume a source of protein, a source of potassium, or a source of sodium.
