Solution Overview
Problem
Current bed control systems fail to provide high-quality sleep experiences by not effectively managing the timing of wake-up processes, posture adjustments, and environmental conditions such as light and wind to ensure users wake up comfortably and reliably.
Innovation Solution
A control apparatus that includes an acquisition unit to gather biological information from sensors and a controller to adjust the bed's back angle and environmental conditions like light and wind based on the user's posture and wake-up timing, ensuring a comfortable wake-up process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bed control system adjusts the back angle and environmental conditions at wake-up time, then the user wakes up more reliably and comfortably, but the system complexity increases due to multiple sensors and coordinated control functions
Solution Approach 1:
The patent combines multiple functions (biological information sensing, posture detection, back angle adjustment, light control, and wind control) into an integrated bed control system. The controller coordinates all these functions through a unified control logic that processes sensor data and executes complementary actions, thereby achieving reliable wake-up while managing system complexity through functional integration.
Solution Approach 2:
The bed control system is designed as a multi-functional apparatus that simultaneously performs biological monitoring, posture recognition, mechanical adjustment, and environmental control. This universal system handles multiple tasks through a single integrated controller, improving wake-up reliability without proportionally increasing complexity.
2Measurement precision
If the system uses multiple sensors to detect biological information and posture, then the wake-up timing accuracy improves, but the device complexity and cost increase
Solution Approach 1:
The sensing system is segmented into specialized sensors for different functions: biological information sensors (heart rate, respiration), posture sensors (pressure distribution), and environmental sensors (light, temperature). Each sensor type targets specific parameters, and the controller processes them separately through dedicated detection routines, achieving high measurement precision while managing complexity through functional segmentation.
Solution Approach 2:
The system implements feedback loops where sensor data continuously monitors user state, and the controller adjusts wake-up timing and control actions based on real-time information. This feedback mechanism ensures accurate wake-up timing by dynamically adapting to actual user conditions, with the controller processing sensor inputs through established algorithms.
3Ease of operation
If the controller coordinates multiple control actions (back angle adjustment, light control, wind control), then the wake-up comfort improves, but the control complexity increases
Solution Approach 1:
The controller executes control actions in a predetermined sequence: first adjusting the back angle to a comfortable position, then gradually increasing light intensity, and finally introducing wind flow. This preliminary ordering of actions ensures wake-up comfort by preparing the environment step-by-step, while the structured sequence reduces control complexity compared to simultaneous multi-parameter adjustment.
Solution Approach 2:
The control system dynamically adjusts multiple parameters (back angle, light intensity, wind speed) based on real-time user response and detected biological information. The controller modifies control actions adaptively during the wake-up process, optimizing comfort while managing complexity through dynamic rather than static control.

AI summary
A control apparatus includes: an acquisition unit configured to acquire first information from a first sensor, the first information including biological information of a user of a bed, the bed including a back section, and a controller configured to determine a timing when the user is to wake up based on the first information. If the user is to wake up, the controller performs at least one of an operation of increasing lightness at the location of the bed and an operation of sending wind toward the bed after increasing an angle of the back section.
