Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple buttons are disposed on the active pen to support multiple functions, then the functional capabilities are improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The voice receiving module and voice analyzing module serve as universal control interfaces for all functions of the active pen. Instead of dedicating separate buttons to each function, a single voice recognition system handles multiple commands (power on/off, color selection, stroke width adjustment, etc.), allowing one component to perform multiple functions and thereby reducing overall device complexity while maintaining versatility
Solution Approach 2:
The patent replaces the mechanical button system with an acoustic field-based voice recognition system. The voice receiving module captures sound waves, and the voice analyzing module processes them to generate control commands, substituting mechanical actuation with acoustic sensing and signal processing to reduce physical components
2Adaptability or versatility
If multiple buttons are disposed on the active pen to support multiple functions, then the functional capabilities are improved, but the manufacturing cost increases
Solution Approach 1:
By using a single voice recognition system to control all functions instead of multiple dedicated buttons, the patent reduces the number of components that need to be manufactured, assembled, and tested. This universal control interface lowers material costs, assembly costs, and quality control expenses while maintaining full functional capabilities
Solution Approach 2:
Replacing mechanical buttons with voice recognition eliminates the need for physical button components, their internal circuitry, and associated assembly processes. This substitution with an acoustic sensing system reduces manufacturing complexity and material costs
3Adaptability or versatility
If a wireless communication module is used to transmit button function information, then the functional capabilities are improved, but the power consumption increases
Solution Approach 1:
The patent replaces wireless electromagnetic communication with electrical signal transmission through the touch panel's existing sensing electrode infrastructure. Voice commands are converted to electrical control commands that travel through the touch panel's conventional signal paths, eliminating the need for separate wireless transmission and reducing power consumption
Solution Approach 2:
The existing touch panel sensing electrode system, originally designed for touch detection, is repurposed to also transmit control commands from the voice recognition system. This multi-functional use of existing infrastructure eliminates the need for dedicated wireless communication hardware and reduces overall power consumption
4Adaptability or versatility
If a wireless communication module is used to transmit button function information, then the functional capabilities are improved, but the device complexity and cost increase
Solution Approach 1:
The touch panel's sensing electrode system performs dual functions: traditional touch input detection and transmission of voice command control signals. This eliminates the need for separate wireless communication modules and their associated antennas, circuitry, and protocols, thereby reducing device complexity while maintaining full functional capabilities
Solution Approach 2:
The patent merges the control command transmission function with the existing touch panel signal transmission infrastructure. By combining these functions into a single communication pathway, the system eliminates redundant components and simplifies the overall device architecture
