Stylus Pen Button Adaptation for EMR and BLE Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stylus pens with a single input button are limited in their ability to utilize multiple short-range communication schemes, such as Bluetooth Low Energy (BLE) and Electromagnetic Resonance (EMR), depending on their proximity to the electronic device, which restricts their functionality and user interaction.
Innovation Solution
A stylus pen with multiple buttons that can switch between different communication schemes based on its position relative to the electronic device, allowing for enhanced interaction and functionality by using a processor and memory to manage signal transmission and reception, enabling specific functions based on button presses and proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stylus pen is equipped with a single input button, then the device structure remains simple, but the ability to utilize multiple short-range communication schemes (BLE and EMR) is limited
Solution Approach 1:
The patent implements dynamic button functionality where a single button on the stylus pen changes its operation mode based on the detected communication scheme (EMR or BLE). The button's function is not fixed but adapts dynamically according to the communication protocol being used, allowing one physical button to serve multiple communication purposes without requiring additional buttons for each scheme
Solution Approach 2:
The single input button on the stylus pen is designed to perform multiple functions across different communication schemes. The same button can trigger different actions depending on whether EMR or BLE communication is active, making the button a universal control element that serves both communication protocols without requiring separate dedicated buttons for each scheme
2Adaptability or versatility
If the stylus pen uses EMR communication when close to the display, then short-range communication is enabled, but the button cannot simultaneously operate for BLE wireless communication
Solution Approach 1:
The button's operational characteristics are made dynamic based on the communication scheme in use. When the stylus is in EMR mode (close to display), the button performs EMR-specific functions. When switched to BLE mode (at distance from display), the same button automatically adapts to perform BLE-specific functions, providing seamless operational transition without requiring the user to understand or manually reconfigure the button's mode
3Adaptability or versatility
If multiple buttons are added to the stylus pen to enable multiple communication schemes, then communication versatility is improved, but the device structure becomes more complex
Solution Approach 1:
The patent employs a universal button design where a single button on the stylus pen handles multiple communication schemes (both EMR and BLE). This universal approach allows one button to replace what would traditionally require multiple dedicated buttons, maintaining full communication versatility while significantly simplifying the physical structure of the stylus pen
Solution Approach 2:
The communication functionality is segmented by communication scheme rather than by physical buttons. The system separates EMR communication operations from BLE communication operations at the software/protocol level, allowing a single physical button to be logically divided into different functional modes depending on which communication scheme is active, eliminating the need for multiple physical buttons
