Solution Overview

Problem

Conventional air conditioner control methods require manual setting of turn-on times, which can lead to inefficient heating and increased power consumption, as they do not account for the user's sleep state or optimal heating timing.

Innovation Solution

A method and device that utilize sensors in wearable devices to detect changes in sleep states, such as transitions from deep to light sleep, to automatically turn on the air conditioner for heating at the appropriate time, determining the optimal timing based on historical sleep data to ensure room temperature is elevated when the user wakes up.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual timing setting is used to turn on the air conditioner, then the heating function can be provided before the user wakes up, but the operation complexity increases and energy efficiency decreases

Engineering Contradiction:
Improveoperation simplicityVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system automatically detects the user's sleep state through sensors and autonomously determines the optimal turn-on time for heating, eliminating the need for manual timing settings. The air conditioner serves itself by using real-time physiological data to make intelligent control decisions, thereby simplifying operation and optimizing energy consumption.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors the user's sleep state through sensors and uses this feedback to dynamically adjust the heating control strategy. By detecting transitions from deep sleep to light sleep, the system receives real-time feedback about user conditions and optimizes the turn-on timing accordingly, improving both operational simplicity and energy efficiency.

Inventive Principle:
Principle #23Feedback

2Temperature

If the air conditioner is turned on early for heating, then the room temperature can be elevated before the user wakes up, but the energy consumption increases

Engineering Contradiction:
Improveroom temperatureVSAvoidpower consumption
Core Design Contradiction:
TemperatureVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary heating action by turning on the air conditioner at the optimal time detected through sleep state monitoring. Instead of fixed early timing, the preliminary action is precisely timed based on when the user transitions from deep to light sleep, ensuring the room is warmed just in time without unnecessary early energy consumption.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system changes the control parameter from fixed time-based scheduling to dynamic state-based scheduling. By monitoring physiological parameters and sleep state transitions, the system adjusts the turn-on timing parameter dynamically, achieving optimal temperature elevation with minimized energy consumption.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If fixed timing is used for turning on the air conditioner, then the heating schedule is simple to implement, but it does not adapt to individual sleep patterns

Engineering Contradiction:
Improvesleep pattern adaptationVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control system transitions from static fixed timing to dynamic adaptive timing. The system continuously monitors sleep state parameters and adjusts the turn-on time dynamically based on detected transitions from deep to light sleep, enabling adaptation to individual sleep patterns while maintaining manageable system complexity through sensor-based automation.

Inventive Principle:
Principle #15Dynamics
