Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing displays lack sufficient illumination in dark environments, as the built-in LED indicators are too dim to effectively illuminate the keyboard or other areas, making operations difficult.
Innovation Solution
A display with an illuminating light system comprising multiple LEDs (red, green, blue) controlled by a unit that switches between normal, energy-saving, and high lighting modes, using a controllable switching component and resistors to adjust brightness and color, with a light guiding mechanism to direct light to specific areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the built-in LED indicators are used for illumination, then the display can provide some light in dark environments, but the brightness is insufficient to effectively illuminate the keyboard or other areas
Solution Approach 1:
The patent implements multiple operating modes (normal mode, energy-saving mode, and high lighting mode) that dynamically adjust the illumination intensity. In high lighting mode, all three LEDs (red, green, blue) are activated simultaneously to provide maximum brightness for keyboard illumination, while in normal mode only one LED is activated for indicator purposes. This dynamic adjustment resolves the contradiction by providing sufficient brightness when needed while maintaining low power consumption during normal operation.
Solution Approach 2:
The patent makes the LED indicator serve dual functions: as a status indicator in normal operation and as an illuminating light for keyboard illumination in high lighting mode. By integrating both functions into a single component system, the patent eliminates the need for separate indicator LEDs and illumination LEDs, thereby resolving the brightness insufficiency issue while maintaining design simplicity.
2Illumination intensity
If multiple LEDs are activated simultaneously to increase illumination brightness, then the visibility for keyboard operations is improved, but the energy consumption increases
Solution Approach 1:
The patent dynamically switches between different operating modes based on user needs. In energy-saving mode, only one or two LEDs are activated to minimize power consumption while providing sufficient indicator functionality. In high lighting mode, all three LEDs are activated simultaneously to provide maximum illumination brightness. This dynamic mode switching resolves the contradiction by allowing the system to adapt power consumption levels to actual operational requirements.
Solution Approach 2:
The patent changes the operational parameters of the LED system by activating different combinations of LEDs (one LED for indicator, two LEDs for energy-saving mode, three LEDs for high lighting mode). This parameter change approach allows the system to adjust illumination intensity and power consumption levels flexibly, resolving the contradiction between brightness and energy consumption.
3Device complexity
If the LED serves only as an indicator lamp, then the design is simple and energy consumption is low, but the illumination function is insufficient for dark environment operations
Solution Approach 1:
The patent makes the existing LED indicator system perform both indicator and illumination functions. By activating all three LEDs (red, green, blue) simultaneously in high lighting mode, the system provides sufficient illumination brightness for keyboard operations and reading in dark environments, while maintaining the simple single-component design without requiring additional illumination LEDs.
Solution Approach 2:
The patent changes the operational state of the LED system from single-LED indicator mode to multi-LED simultaneous activation mode for illumination. This parameter change allows the existing simple structure to provide sufficient illumination brightness by utilizing all available LED components, resolving the contradiction between design simplicity and illumination effectiveness.
