Adaptive Wake-Up Signal for Blood Pressure Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The sudden awakening of individuals with hypertension by traditional alarm systems during the morning peak blood pressure period can lead to severe health risks due to sudden blood pressure increases, posing a hidden danger to their cardiovascular health.
Innovation Solution
A user reminding method and apparatus that determines a user's safety level based on their physical status and blood pressure values, sending customized reminding signals to gradually wake users, thereby avoiding sudden blood pressure spikes and improving safety and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a traditional alarm rings suddenly to wake up a user, then the user can be awakened promptly, but the user's blood pressure increases suddenly causing health risks
Solution Approach 1:
The alarm system dynamically adjusts the awakening strategy based on real-time blood pressure monitoring. When blood pressure is normal, a standard alarm is used. When blood pressure is elevated, the system transitions to a gradual awakening mode with softened audio output and extended duration, resolving the contradiction between quick wake-up and health safety
Solution Approach 2:
The system changes the parameters of the alarm signal based on blood pressure levels. The audio output level, duration, and type of alarm signal are adjusted according to the monitored blood pressure values, transforming a fixed alarm into an adaptive signal that prevents harmful blood pressure spikes while ensuring effective awakening
2Reliability
If blood pressure monitoring and analysis systems are added to terminal devices, then user safety can be improved, but device complexity increases
Solution Approach 1:
The terminal device integrates multiple functions into a single system: blood pressure monitoring, sleep state detection, alarm signal generation, and adaptive control. This multi-functional integration improves user safety without proportionally increasing complexity, as the same hardware components serve multiple purposes
Solution Approach 2:
The system automatically monitors blood pressure, analyzes sleep states, determines safety levels, and adjusts alarm parameters without requiring manual user intervention. The device self-regulates the awakening process based on real-time physiological data, reducing the need for complex user interfaces and manual configurations

AI summary
A user reminding method and apparatus, and a mobile terminal includes, obtaining, by a terminal device, a physical status of a user and a first blood pressure value of the user when a time difference between a current time and a preset reminding time is less than a first threshold; determining a first safety level based on the physical status and the first blood pressure value; and sending a first reminding signal in a manner corresponding to the first safety level.
