Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld electronic devices, such as smartphones and laptops, lack a built-in lighting solution for navigation and keyboard illumination in low-light conditions, requiring external light sources and separate flashlights.
Innovation Solution
Integration of a rechargeable LED lighting device into the casing of electronic equipment, providing a directed illumination source that avoids glare on display screens and is powered by the device's existing power source, allowing simultaneous charging with other electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lighting device is integrated into handheld electronic equipment, then illumination functionality is provided for navigation and keyboard illumination, but device complexity increases
Solution Approach 1:
The patent combines the lighting device with the handheld electronic equipment by integrating the LED light source, battery, and control circuitry into the device housing. The light is mounted within the casing and powered by the device's existing battery or a dedicated rechargeable battery, creating a unified multi-functional device that eliminates the need for separate flashlights or external lighting equipment.
Solution Approach 2:
The integrated lighting device serves multiple functions including navigation illumination, keyboard illumination for laptops, and emergency lighting. The system can be activated through various methods such as button presses, motion sensors, or automatic triggering, providing universal illumination solutions across different usage scenarios and device types.
2Object-affected harmful factors
If the light provides directed illumination, then glare on display screens is avoided, but manufacturing precision requirements increase
Solution Approach 1:
The lighting device employs directed or focused illumination that concentrates light in specific zones such as the keyboard area or navigation path while minimizing light dispersion toward the display screen. This localized lighting approach reduces glare on the screen while providing adequate illumination where needed, achieved through strategic positioning of LEDs and use of reflectors or diffusers.
3Loss of time
If the lighting device is recharged with the same recharger, then loss of time for charging is reduced, but use of energy from the power source increases
Solution Approach 1:
The lighting device shares the power source and charging infrastructure with the main handheld electronic equipment. The same rechargeable battery or external power source charges both the device and its integrated light, eliminating the need for separate charging equipment and reducing overall charging time compared to maintaining separate power systems.
