Gradual Lamp Fade-In Alarm Clock Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional alarm clocks with integrated lamps startle or irritate users with abrupt light and sound, making waking up uncomfortable due to sudden illumination and noise.
Innovation Solution
An alarm clock with a gradually fading-in lamp and adjustable alarm activation, where the lamp gradually increases brightness and the alarm sounds only after the lamp is fully lit, using a microcomputer with a timer to control the lamp drive and pulse width signals to manage the light and sound activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lamp is immediately lit up at the set time, then the alarm function is activated promptly, but the user is dazzled and irritated by the abrupt light
Solution Approach 1:
The lamp is activated in advance of the alarm signal, gradually increasing its brightness before the alarm sounds. This preliminary action allows the user's eyes to adjust to the light progressively, preventing dazzling and irritation while ensuring the alarm is activated promptly afterward.
2Reliability
If the alarm is issued immediately at the set time, then the alarm function responds quickly, but the user is startled and irritated by the abrupt sound
Solution Approach 1:
The lamp is activated and gradually brightened before the alarm sound is issued. This preliminary visual activation prepares the user's senses in advance, reducing the startle response and irritation from the abrupt alarm sound while maintaining quick alarm response.
Solution Approach 2:
The lamp brightness is dynamically adjusted over time, transitioning from off to gradually increasing brightness rather than abrupt on. This dynamic adjustment creates a smooth transition that prevents startling the user while maintaining timely alarm activation.
3Reliability
If the lamp turns on completely at the set time, then the lighting function is activated fully, but the user experiences discomfort from the sudden brightness change
Solution Approach 1:
The lamp brightness is dynamically controlled to increase gradually over a period of time rather than switching on completely at once. This dynamic brightness adjustment maintains full lamp activation functionality while significantly improving user comfort during the wake-up process by avoiding sudden brightness changes.
Solution Approach 2:
The lamp's brightness parameter is changed progressively over time rather than abruptly. The brightness transitions from 0% to 100% in a controlled gradual manner, maintaining complete lamp activation while improving comfort by avoiding sudden parameter changes that would dazzle the user.

AI summary
An alarm clock includes a power supply unit; a key input setting unit (110); the lamp (140); a microcomputer (120) configured to be provided with a timer having a clock function; the time display unit (170); the alarm module (160) configured to be selectively turned on and off in response to the alarm control signal output by the microcomputer (120); a lamp power supply control unit (130) configured to be selectively switched on and off in response to the lamp drive control signal output by the microcomputer (120); and a lamp current adjustment unit (160) configured to perform control so that an amount of current flowing through the lamp (140) gradually increases based on the pulse width signal output by the microcomputer (120). The lamp gradually fades in and an alarm is issued after the lamp has been completely lit up.
