Solution Overview

Problem

Conventional keyboards with lighting capabilities can only operate in a binary light mode, where all patterns on a key are either bright or dark, failing to provide individual control for each pattern to suit different scenarios.

Innovation Solution

A keyswitch assembly comprising a display unit, carrier, contact pads, a light-shielding layer with transparent patterns, and a transparent keycap, allowing each pattern to be independently controlled for brightness, using a manufacturing method that forms contact pads, positions the display unit, forms a light-shielding layer with transparent patterns, and positions the transparent keycap.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If all patterns on one key are switched together in a binary light mode, then the structure is simple and easy to control, but the adaptability to different scenarios is limited

Engineering Contradiction:
Improveadaptability to different scenariosVSAvoidcontrol complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the light patterns on a key into multiple independently controllable groups. Each group of patterns can be controlled separately, allowing selective illumination of different patterns based on different scenarios. This segmentation enables the keyboard to adapt to various usage situations without requiring complete reconfiguration of the lighting system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic control of light patterns by allowing different patterns to be independently switched on and off based on real-time operational needs. The system can dynamically adjust which patterns are illuminated depending on the current scenario, providing versatility while maintaining manageable control through programmed scenarios.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple patterns on one key are individually controlled, then the adaptability to different scenarios is improved, but the device complexity increases

Engineering Contradiction:
Improveindividual pattern controlVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the key patterns into multiple independently controllable segments or groups. Each group can be individually controlled through separate control signals, enabling fine-grained adjustment of which patterns are illuminated. This segmentation approach provides individual pattern control capability while organizing the complexity into manageable discrete units.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a universal control system that can handle multiple lighting scenarios through a standardized interface. The same hardware infrastructure supports various lighting configurations and scenarios, allowing the system to perform multiple functions without requiring separate dedicated controls for each scenario.

Inventive Principle:
Principle #6Universality (Multi-functionality)
