Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illuminated keyboards have limited adjustability in brightness and illumination effect for specific keys due to the fixed location of the light-emitting unit in the backlight module.
Innovation Solution
The light-emitting module includes a reflector plate, a light guiding plate, a light shielding plate, a base plate, a thin film circuit board, and a light-emitting element, where the light-emitting elements are disposed on the thin film circuit board, allowing for easier replacement and adjustment of the illuminating effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light-emitting unit is fixed in the backlight module, then the structural design is simplified, but the adjustability of brightness for specific keys is limited
Solution Approach 1:
The backlight module is divided into multiple independent light-emitting units, each corresponding to a specific key region. This segmentation allows individual adjustment of brightness for different keys while maintaining a relatively simple overall structure. Each light-emitting unit can be controlled independently through the control circuit board, enabling selective illumination adjustment without redesigning the entire backlight system.
Solution Approach 2:
The patent introduces a control circuit board that enables dynamic adjustment of brightness for specific keys. The light-emitting units are designed to be controllable individually, allowing the system to adapt brightness levels dynamically based on user needs. This dynamic control capability resolves the contradiction by providing adjustability without requiring a completely complex reconfigurable structure.
2Adaptability or versatility
If the light-emitting unit location is unchangeable, then the manufacturing process is simplified, but the illuminated effect of each key is limited
Solution Approach 1:
The backlight module is segmented into multiple light-emitting units that can be independently positioned and controlled. This segmentation allows for flexible illumination patterns across different keys while maintaining standardized manufacturing processes for each module. The modular design enables easy assembly and positioning during manufacturing.
Solution Approach 2:
The light-emitting units are designed with universal mounting structures and standardized interfaces, allowing them to be manufactured using the same processes but deployed in various configurations. The control circuit board provides multi-functional control capabilities, enabling a single hardware design to achieve different illumination effects through software control.
3Ease of operation
If a conventional backlight module is used, then the device structure is simplified, but the ability to adjust brightness of specific keys is difficult
Solution Approach 1:
The patent incorporates a control circuit board that provides dynamic brightness adjustment capabilities for individual keys. The light-emitting units are designed to respond to control signals, enabling users to adjust brightness levels easily through software or control interfaces. This dynamic control system maintains operational simplicity while enhancing functionality.
Solution Approach 2:
The control circuit board acts as an intermediary between the user interface and the light-emitting units. It receives adjustment commands and translates them into appropriate control signals for the individual light-emitting units, thereby simplifying the user interaction while managing the complexity of individual key control through a centralized control mechanism.
