Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each key is independently connected to MCU with separate input and output pins, then key detection function is achieved, but PCB layout becomes complex and wiring increases significantly
Solution Approach 1:
The patent merges multiple independent key connection functions into a single integrated circuit chip. Each key is assigned to a specific integrated circuit chip, and multiple chips are connected in cascade through data lines, consolidating what would otherwise require hundreds of separate pin connections into a streamlined architecture with significantly reduced PCB complexity.
Solution Approach 2:
The integrated circuit chip performs multiple functions: key detection, data transmission, and RGB color control. By making the chip universal and multi-functional, the patent eliminates the need for separate dedicated circuits for each function, thereby reducing overall system complexity while maintaining full functionality.
2Illumination intensity
If LED lights are added to each key for aesthetics, then visual effect is improved, but number of wiring and components doubles leading to tighter PCB layout
Solution Approach 1:
The patent combines the RGB color driving circuit with the key detection function within the same integrated circuit chip. This merging means that LED control signals are generated and transmitted through the existing data line infrastructure, eliminating the need for separate LED control wiring and reducing component count while maintaining full RGB lighting capability.
Solution Approach 2:
The integrated circuit chip is designed as a universal module that simultaneously handles key detection, data transmission, and RGB LED control. This multi-functionality allows a single chip to replace what would traditionally require multiple separate components, thereby reducing wiring complexity while providing both aesthetic lighting and functional key detection.
3Adaptability or versatility
If separate circuits are used for key detection and RGB control, then functional independence is achieved, but circuit structure becomes complex and operational stability decreases
Solution Approach 1:
The patent merges key detection and RGB control circuits into a single integrated circuit chip that operates under unified control from the MCU. This consolidation maintains functional independence through software-controlled task separation while eliminating the complexity of multiple independent hardware circuits, thereby improving operational stability.
Solution Approach 2:
The integrated circuit chip is designed as a universal module capable of performing both key detection and RGB control functions. By making the circuit universal rather than specialized, the patent reduces overall circuit structure complexity while preserving functional versatility through software-based function assignment.
4Reliability
If multiple independent circuits are implemented, then specific functions are achieved, but number of components increases and power consumption rises
Solution Approach 1:
The patent merges key detection, data transmission, and RGB control functions into a single integrated circuit chip. This consolidation dramatically reduces component count compared to implementing separate independent circuits for each function, while maintaining full functionality through the chip's integrated design and the MCU's coordination.
