Wake-Up Alarm System with Motion-Triggered Illumination Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illumination control systems for wake-up times do not account for individual user preferences and convenience, as they require users to manually adjust illuminance after waking up and lack detection of wake-up events.
Innovation Solution
A method and system where a communications terminal connected to an illumination device via a network controls the illuminance state before and after wake-up time, using first and second illumination settings to automatically adjust from a dim state to normal brightness based on user motion detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the illumination device uses a fixed illuminance setting for wake-up time, then the control system is simple, but it cannot adapt to individual user preferences and convenience
Solution Approach 1:
The system stores multiple illumination setting combinations (first illumination setting before wake-up, second illumination setting after wake-up) in advance. The communications terminal automatically selects and applies the appropriate setting combination based on the detected wake-up event, eliminating the need for real-time manual adjustment while adapting to user preferences.
Solution Approach 2:
The illumination settings are made dynamic by transitioning from a single fixed illuminance value to multiple time-dependent setting combinations. The system switches between the first illumination setting (dim state before wake-up) and the second illumination setting (normal brightness after wake-up) based on the user's sleep and wake states, providing adaptability without excessive complexity.
2Ease of operation
If the system requires manual adjustment of illuminance after waking up, then device complexity is low, but ease of operation deteriorates
Solution Approach 1:
The system performs self-service by automatically detecting the wake-up event through motion sensing and autonomously switching from the first illumination setting to the second illumination setting. This eliminates the need for manual user intervention while enhancing convenience, with the complexity managed through automated algorithms.
Solution Approach 2:
The system uses motion detection feedback to determine whether the user has woken up. When motion exceeding a threshold is detected, the system interprets this as a wake-up event and automatically adjusts the illumination settings accordingly, creating a closed-loop control system that improves ease of operation.
3Productivity
If the system does not detect wake-up events automatically, then device complexity is low, but productivity and user experience deteriorate
Solution Approach 1:
The system replaces manual wake-up detection (mechanical/user-action-based) with automated motion sensing technology. The motion sensor detects physical movements associated with waking up, and the communications terminal processes this data to automatically trigger illumination setting changes, significantly improving detection efficiency.
Solution Approach 2:
The communications terminal acts as an intermediary between the motion sensor and the illumination device. It receives motion detection data, processes it to determine wake-up events, and sends control signals to adjust illumination settings, thereby enabling automatic wake-up detection without requiring direct complex integration between sensors and illumination controls.
4Illumination intensity
If the illumination device maintains constant brightness, then control simplicity is high, but it cannot provide appropriate illuminance for different wake-up stages
Solution Approach 1:
The illumination control is segmented into distinct time-based phases: the first illumination setting for the period before wake-up (dim state) and the second illumination setting for the period after wake-up (normal brightness). This segmentation allows appropriate illuminance for different wake-up stages while managing complexity through clear phase separation.
Solution Approach 2:
The system changes illumination parameters (brightness level, color temperature) based on the wake-up stage. By transitioning from the first illumination setting with lower brightness to the second illumination setting with higher brightness, the system provides appropriate illuminance for different stages of the wake-up process.

AI summary
A method for controlling a communications terminal is provided. The method includes causing a computer included in the communications terminal to store first illumination setting information and second illumination setting information in the memory; causing the computer of the communications terminal to transmit, at a certain illumination start time at which the illumination device is to be turned on, a first control signal corresponding to the first illumination setting information to the illumination device such that the illumination device is set to the first illumination state; and causing the computer of the communications terminal to transmit, in a case where the sensor senses a motion of the communications terminal after the certain illumination start time has passed, a second control signal corresponding to the second illumination setting information to the illumination device such that the illumination device is set to the second illumination state.
