Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional backlight module illuminates the entire keyboard device, then the keyboard device provides basic lighting, but the visual feedback effect is insufficient and lacks diversity
Solution Approach 1:
The backlight module is divided into multiple independent light emitting components, each corresponding to specific character symbols on key units. This segmentation allows selective illumination of different character symbols based on input modes, transforming a uniform lighting system into a diversified visual feedback system that can highlight specific characters while keeping others dark.
Solution Approach 2:
Different regions of the keyboard are provided with different illumination characteristics. By controlling individual light emitting components, the system creates local quality variations where specific character symbols receive illumination while others remain dark, providing context-aware visual feedback that adapts to different input modes.
2Adaptability or versatility
If multiple light emitting components are added to each key unit to provide diversified illumination, then the visual feedback effect is enhanced, but the device complexity increases
Solution Approach 1:
The light emitting components serve multiple functions: they can illuminate different character symbols on the same key unit, support various input modes, and provide contextual visual feedback. This multi-functionality reduces the need for separate lighting systems for different purposes, as a single set of light emitting components can handle diverse illumination requirements through selective activation.
Solution Approach 2:
The patent combines multiple character symbols on a single key unit and uses shared light emitting components to illuminate them. Instead of having separate lighting systems for each character or key, the system merges the illumination function into a unified backlight module where light emitting components are strategically positioned to serve multiple characters across multiple keys.
3Loss of information
If selective illumination of specific character symbols is implemented, then the current input mode is emphasized, but the control system complexity increases
Solution Approach 1:
The system implements feedback by detecting the current input mode and automatically adjusting the illumination pattern accordingly. The detection module monitors the input mode state and feeds this information back to the control system, which then activates the appropriate light emitting components to highlight the relevant character symbols, creating a closed-loop system that adapts to user input preferences.
Solution Approach 2:
The light emitting components are pre-positioned and configured to correspond to specific character symbols before operation. This preliminary arrangement allows the control system to simply activate predetermined components based on the detected input mode, rather than dynamically calculating which components to activate, thereby reducing real-time control complexity.
