Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current illumination devices for electronic devices, such as desk lamps or clip-on lamps, often cause dazzling reflective light that can be uncomfortable for users due to the difficulty in adjusting the angle to avoid direct irradiation on the display screen or keyboard.
Innovation Solution
An illumination device with a clamping portion and a light source positioned at a fixed angle relative to the keyboard surface, using a lampshade and optical design to direct light away from the user's eyes, and incorporating features like an optical lens and inclination sensor for optimal positioning and adjustable settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the illumination device is manually adjusted to change the angle, then the user can find a suitable position, but it takes time and effort and is not easy to find the right angle
Solution Approach 1:
The illumination device incorporates an inclination sensor that automatically detects the angle between the illumination device and the keyboard surface, and a control unit that automatically adjusts the illumination angle based on sensor feedback, eliminating the need for manual adjustment and enabling the device to self-optimize its positioning
Solution Approach 2:
The system uses an inclination sensor to continuously monitor the angle of the illumination device relative to the keyboard surface and provides feedback to the control unit, which then adjusts the illumination angle accordingly to maintain optimal positioning without user intervention
2Illumination intensity
If the light source is positioned to illuminate the keyboard, then the keyboard is well-lit, but the reflective light may directly enter users' eyes and cause discomfort
Solution Approach 1:
The illumination angle is dynamically adjusted based on the detected angle between the illumination device and the keyboard surface, allowing the system to adapt in real-time to different usage scenarios and maintain optimal illumination while preventing glare
Solution Approach 2:
The control unit changes the illumination parameters (angle, intensity) based on feedback from the inclination sensor and ambient light sensor, optimizing the balance between providing sufficient keyboard illumination and preventing reflective light from entering the user's eyes
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces eye discomfort by ensuring that reflective light does not directly enter the user's eyes, providing a comfortable and efficient illumination experience with adjustable brightness and color temperature settings.
Implementation Method 1
The light source is disposed in the lampshade and provides an illuminating light having an optical axis, wherein a fixed angle is formed between the optical axis of the illuminating light and the keyboard surface
Implementation Method 2
the reflective light provided by the illumination device will not dazzle users' eyes and the reflective light reflected from the display screen or the keyboard will not directly enter users' eyes
