Solution Overview
Problem
Conventional keyboards lack aesthetics and engagement, making key press detection solely based on mechanical sound dull and unentertaining.
Innovation Solution
A light emitting keyboard with programmable controllers, LED light sources, and switch circuits that activate surrounding keys when a key is pressed, offering various modes such as single key, surrounding keys, breathing light, and ripple styles to enhance user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional keyboard without light sources is used, then the device complexity is low and manufacturing cost is low, but the aesthetics and user engagement are poor
Solution Approach 1:
The patent merges the keyboard key structure with light-emitting components (LEDs or other light sources) into an integrated unit. Each key cap or key housing incorporates a light source that illuminates through or around the key, combining the mechanical input function with optical feedback function into a single integrated component structure.
Solution Approach 2:
The patent employs light sources that can emit different colors or illumination patterns to indicate various keyboard states, functions, or modes. The controller adjusts the illumination characteristics (color, intensity, pattern) to provide visual feedback corresponding to different operational states, enhancing user engagement and aesthetic appeal.
2Illumination intensity
If light sources are added to each key, then the aesthetics and sense of operation are improved, but the use of energy increases
Solution Approach 1:
The patent implements periodic or intermittent illumination rather than continuous lighting. The controller activates light sources only during specific events such as key presses, state changes, or in rhythmic patterns, thereby reducing overall energy consumption while maintaining visual engagement and aesthetic appeal during active use.
Solution Approach 2:
The illumination system is designed to be dynamic and adaptive, adjusting light intensity, duration, and activation patterns based on usage context. The controller modulates the light sources to provide enhanced visual feedback during active typing while reducing or eliminating illumination during idle periods, optimizing the balance between aesthetics and energy consumption.
3Illumination intensity
If light sources are added to each key, then the aesthetics and sense of operation are improved, but the manufacturing cost increases
Solution Approach 1:
The patent structures the keyboard as modular units where each key or key group can be manufactured and assembled independently. The light sources are integrated into individual key caps or key housings as separate modules, allowing for standardized mass production of key units that can be assembled into the complete keyboard, thereby reducing overall manufacturing complexity and cost.
Solution Approach 2:
The patent designs the light-emitting key structure to serve multiple functions: mechanical key input, visual indication of key state, and aesthetic enhancement. This multi-functionality reduces the need for separate components and systems, consolidating functions into integrated key units that simplify the overall manufacturing process and reduce component count.
