Stylus Wireless Link Control for Noise-Induced Abnormal Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Styluses experience abnormal functions due to noise interference during wireless communication with electronic devices, such as tablet computers and mobile phones, leading to inefficiencies in interaction.
Innovation Solution
An electronic device detects noise affecting wireless communication with a stylus and adjusts control parameters like voltage and frequency to mitigate interference, sending indication information to the stylus to adjust these parameters accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication parameters are kept fixed for stable communication, then communication stability is maintained, but noise interference causes abnormal functions and reduces reliability
Solution Approach 1:
The patent implements dynamic adjustment of wireless communication parameters (voltage and frequency) based on real-time noise detection. The electronic device continuously monitors noise levels and dynamically changes communication parameters to adapt to varying interference conditions, transforming the static parameter system into a dynamic one that can respond to environmental changes and maintain reliable communication despite noise interference.
Solution Approach 2:
The patent directly applies parameter changes by modifying voltage and frequency values in response to detected noise. When noise is detected, the system changes these physical parameters to values that are less susceptible to interference, thereby resolving the contradiction between maintaining stable parameters for reliability and adapting to changing noise conditions.
2Reliability
If communication parameters are dynamically adjusted to counteract noise, then anti-interference ability is improved, but system complexity increases due to noise detection and parameter adjustment mechanisms
Solution Approach 1:
The patent implements a feedback mechanism where the electronic device detects noise levels and uses this information to adjust communication parameters. The noise detection module continuously monitors the communication environment and feeds this information back to the parameter adjustment logic, creating a closed-loop control system that automatically responds to interference without requiring complex manual intervention or sophisticated algorithms.
Solution Approach 2:
The system performs self-adjustment by automatically detecting noise and modifying its own communication parameters without external intervention. The electronic device and stylus autonomously monitor their communication environment and self-correct parameter settings to maintain optimal performance, reducing the need for complex external control systems.
