Solution Overview

Problem

Current medical treatments, particularly for conditions like cancer, often result in severe side effects such as cancer-related fatigue due to disruption of the patient's circadian rhythm, which existing technologies fail to adequately address, leading to reduced medication effectiveness and patient compliance.

Innovation Solution

A circadian rhythm entrainment platform that uses light therapy to synchronize a patient's circadian rhythm with their medication schedule, determining individualized light therapy regimens based on melatonin levels and sleep patterns to minimize side effects and enhance treatment efficacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If medication is administered to treat serious conditions, then treatment effectiveness is improved, but circadian rhythm disruption occurs causing severe side effects

Engineering Contradiction:

Improvemedication effectivenessVSAvoidcircadian rhythm disruption

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system applies light therapy in advance and during medication treatment to counteract circadian rhythm disruption before it fully develops. By detecting early signs of rhythm disturbance and applying compensatory light exposure, the system prevents severe side effects while maintaining medication effectiveness.

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The system continuously monitors circadian rhythm indicators (melatonin levels, sleep patterns, activity levels) and uses this feedback to dynamically adjust light therapy parameters. This closed-loop control ensures that light therapy effectively counteracts medication-induced circadian disruption while minimizing side effects.

Inventive Principle:

Principle #23Feedback

2Object-affected harmful factors

If light therapy is applied to correct circadian rhythm, then side effects are reduced, but treatment complexity increases

Engineering Contradiction:

Improveside effectsVSAvoidtreatment system complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system integrates multiple functions into a single platform: circadian rhythm monitoring, medication tracking, light therapy delivery, and automated regimen adjustment. This multi-functional integration reduces the need for separate devices and simplifies the overall treatment approach despite the complexity of individual components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system automatically adjusts light therapy parameters based on real-time circadian rhythm data without requiring manual intervention from healthcare providers or patients. The automated algorithm interprets monitoring data and modifies treatment regimens independently, reducing operational complexity.

Inventive Principle:

Principle #25Self-service

3Productivity

If individualized light therapy regimens are implemented, then medication compliance is enhanced, but monitoring and customization requirements increase

Engineering Contradiction:

Improvemedication complianceVSAvoidmonitoring requirements

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system uses real-time feedback from circadian rhythm monitoring to automatically customize light therapy regimens for each patient. By continuously tracking individual responses and adjusting parameters accordingly, the system enhances compliance without requiring manual customization by healthcare providers.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system dynamically modifies light therapy parameters (intensity, duration, timing, spectral composition) based on individual patient responses and circadian rhythm data. This automated parameter optimization improves compliance while reducing the burden of manual monitoring and adjustment.

AI summary

A circadian rhythm entrainment platform can use medication circadian profiles that include mappings of medications to circadian rhythm disruptions and can make conversions of such circadian rhythm disruptions to administrations of light therapy to adjust for the disruptions. The circadian rhythm entrainment platform can specify how to entrain a patient's circadian rhythm using light therapy to compensate for or anticipate side effects of medications and for optimizing medication schedules for a patient's circadian rhythm so as to minimize side effects and increase medication effectiveness. The circadian rhythm entrainment platform can also gather information on the effects of medications on circadian rhythms and interact with patients, medical providers, and other providers in relation to light therapy.
