Insomnia Treatment Device Using Adaptive Bedtime Sleepiness Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insomnia treatment systems burden users with frequent sleepiness tests, making it difficult to accurately evaluate cognitive and psychomotor abilities throughout the day and requiring continuous testing, which can lead to abandonment.
Innovation Solution
A system that sets a user's bedtime based on sleep efficiency and schedules a sleepiness test earlier than bedtime, with optional reminders at varying times, allowing for a single daily test that aligns with insomnia improvement, thereby minimizing user burden and improving test relevance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sleepiness tests are performed throughout the day to accurately evaluate cognitive and psychomotor abilities, then measurement precision is improved, but device complexity and user burden increase
Solution Approach 1:
The system performs a sleepiness test in advance before bedtime to evaluate the user's cognitive and psychomotor abilities. This preliminary assessment provides insight into the user's sleep quality and alertness level without requiring multiple tests throughout the day, thereby reducing user burden while still achieving meaningful measurement
Solution Approach 2:
The invention extracts the essential measurement function by performing a single sleepiness test at a specific time (before bedtime) rather than requiring multiple tests throughout the day. This extraction of the critical measurement moment maintains evaluation accuracy while significantly reducing the complexity and burden of frequent testing
2Reliability
If continuous testing is performed to monitor insomnia improvement, then reliability of treatment monitoring is improved, but ease of operation deteriorates due to user abandonment
Solution Approach 1:
The system implements periodic sleepiness testing at predetermined intervals (specifically before bedtime) rather than requiring continuous testing throughout the day. This periodic approach maintains reliable monitoring of insomnia improvement while significantly reducing user burden and the likelihood of treatment abandonment
Solution Approach 2:
By performing the sleepiness test in advance before bedtime, the system establishes a consistent, predictable testing routine that is easy for users to follow. This preliminary timing ensures continuous monitoring of treatment progress while maintaining high ease of operation and user retention
3Productivity
If sleepiness tests are performed at fixed predetermined times, then productivity of test execution is improved, but adaptability to individual insomnia states deteriorates
Solution Approach 1:
The system dynamically adjusts the bedtime parameter based on individual user data and insomnia improvement state. By setting the sleepiness test time adaptively relative to the user's personalized bedtime rather than using a fixed predetermined time, the system maintains both execution efficiency and adaptability to individual conditions

AI summary
Provided is an insomnia treatment assistance device including: a bedtime setting unit (14) that sets a bedtime of a user on the basis of sleep efficiency of the user and notifies it to the user; an execution time setting unit (15) that sets a time earlier than the bedtime by a first predetermined time as a sleepiness test execution time; and a reminder message presentation unit (16) that presents a reminder message for prompting execution of a sleepiness test to the user at the sleepiness test execution time. The sleepiness test can be performed at an appropriate time depending on the sleep efficiency that suggests a degree of amelioration of insomnia even in a case where the sleepiness test is performed once a day. It is possible to appropriately measure user's sleepiness depending on the degree of amelioration of insomnia while minimizing a user's burden for the sleepiness test.
