Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing illuminated keyboards with dynamic light effects is time-consuming due to the need for manual updating of driver color data tables when the arrangement of light emitting diodes changes, as the pre-set data does not match the new layout, requiring significant human effort and time.
Innovation Solution
A method and apparatus that automatically generate a second driver color data table matched with the current key light driver array arrangement by using a microprocessor to process a first driver color data table unmatched with the array, allowing for rapid updating of light effects without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual updating of driver color data tables is used when key light arrangement changes, then design accuracy can be maintained, but time consumption and labor effort increase significantly
Solution Approach 1:
The system performs self-service by automatically generating the second driver color data table through the microprocessor comparing the first driver color data table with the actual key light arrangement, eliminating the need for manual intervention and significantly reducing design time while maintaining data accuracy
Solution Approach 2:
The manual mechanical process of updating driver color data tables is replaced with an automated electronic system where the microprocessor electronically compares and generates updated data tables, substituting human labor with computational processing
2Productivity
If pre-set driver color data tables are used without updating, then design time is reduced, but the light effects become incorrect when arrangement changes
Solution Approach 1:
The system implements feedback by comparing the first driver color data table with the actual key light arrangement order stored in the microprocessor, detecting mismatches and automatically generating corrected second driver color data tables to ensure light effect accuracy
Solution Approach 2:
The system performs preliminary action by pre-storing the correct arrangement order of key lights in the microprocessor memory, enabling automatic comparison and correction before actual keyboard operation, ensuring reliability without manual intervention
3Loss of time
If automatic generation of driver color data tables is implemented, then time consumption is reduced, but system complexity increases
Solution Approach 1:
The microprocessor serves multiple functions: storing the key light arrangement order, comparing driver color data tables, generating updated data tables, and controlling the key light driver array, consolidating what could be separate complex components into a single multi-functional device
