Innovation Solution
A dual stylus and dual controller system that can transmit and receive signals according to multiple systems, with the stylus detecting writing pressure to initiate signal reception and switch operation modes based on received signals, ensuring immediate mode setting and optimal communication by transmitting specific function information and switching instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the dual stylus waits to receive signals from the sensor controller before determining operation mode, then it can identify the sensor controller type accurately, but the time required from contact to mode decision increases, causing user inconvenience during quick operations
Solution Approach 1:
The dual stylus performs preliminary actions by detecting contact with the touch surface immediately and proactively transmitting identification signals without waiting for sensor controller signals. This allows the stylus to determine the operation mode based on the sensor controller's response to its transmitted signal, significantly reducing the time from contact to mode decision while maintaining accurate identification.
2Adaptability or versatility
If the dual stylus and dual controller operate according to lower priority systems, then they can maintain intermittent signal transmission and reception, but they fail to achieve optimal communication performance and compatibility with higher priority systems
Solution Approach 1:
The dual stylus and dual controller dynamically change their operational parameters by transmitting and receiving signals according to different systems based on priority levels. When a higher priority system is detected, the stylus switches to that system's communication protocol, ensuring optimal communication performance and reliability while maintaining the ability to adapt to multiple systems through parameter adjustment.

AI summary
A method is carried out by a stylus, wherein the stylus is a dual stylus configured to be capable of transmitting signals pursuant to both a first system and a second system and receiving at least a signal pursuant to the first system. The dual stylus has a detection function of detecting a writing pressure applied to a stylus (pen) tip. The method includes detecting contact between the stylus and a touch surface based on the writing pressure detected by the detection function, activating a signal reception operation pursuant to the first system for a predetermined time period, and, responsive to reception of a signal pursuant to the first system in the predetermined time period, setting an operation mode of the stylus to a first operation mode, in which signals are transmitted and received pursuant to the first system.
