Solution Overview
Problem
Current electronic devices using stylus brushes for input lack the ability to replicate the tactile experience of actual writing materials, as they primarily function similarly to stylus pens, failing to provide a genuine feeling of drawing with brushes.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stylus brush is used as an input device, then the apparent shape resembles a general brush providing intuitive drawing input, but the input operation performs in the same manner as a stylus pen without replicating actual writing material experience
Solution Approach 1:
The system changes the parameters of signal detection by analyzing multiple characteristics (signal strength, contact area, movement speed, pressure) rather than relying on a single parameter. This allows the system to distinguish between different input devices and simulate appropriate writing effects, resolving the contradiction between intuitive operation and realistic simulation.
Solution Approach 2:
The touch panel is designed to serve multiple functions: it can detect not only touch position but also signal strength, contact area, and movement characteristics. This multi-functionality enables the system to handle both stylus pen and stylus brush inputs with appropriate simulations, achieving versatility while maintaining ease of operation.
2Device complexity
If the electronic device detects only basic touch input, then the system complexity remains low, but the device cannot provide varied drawing effects based on input device characteristics
Solution Approach 1:
The detection system is segmented into multiple analysis components: signal strength detection, contact area measurement, movement speed calculation, and pressure sensing. Each component handles a specific aspect of input characterization, allowing the system to achieve high adaptability while keeping individual components relatively simple and manageable.
3Manufacturing precision
If the system processes detailed input characteristics, then realistic drawing effects can be achieved, but the processing time and computational resources increase
Solution Approach 1:
The system applies partial processing by selecting and prioritizing the most relevant input characteristics for each drawing operation. Not all parameters are processed with equal depth - the system adjusts the level of analysis based on the specific input device and drawing context, achieving sufficient precision without excessive processing time.
