Stylus Erasing Device Physical and Virtual Message Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touchpad peripherals, such as styluses, lack functionality beyond basic touch operations and do not enable efficient erasure of messages on touch-sensitive devices like touchpads and electronic screens.
Innovation Solution
A message erasing device with a device body, processing module, and erasing module, featuring a movable unit and clearing unit, which allows for the erasure of actual messages on touch-sensitive devices and generates corresponding erasing signals to synchronize the removal of virtual messages on electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stylus is used for touchpad operation, then basic touch functionality is achieved, but additional functions such as message erasure are not available
Solution Approach 1:
The stylus is designed to perform multiple functions: it can both write messages on the touchpad surface and erase them. The erasing module includes a clearing unit that contacts the touchpad to erase physical messages, while the movable unit activates a processing module to generate erasing signals for virtual messages, making the stylus a universal tool for both creation and deletion of messages
Solution Approach 2:
The stylus is divided into functional segments: a device body housing the processing module, an erasing module with a clearing unit for physical erasure, and a movable unit that triggers the erasing function. This segmentation allows each component to specialize in a specific task while maintaining overall functionality
2Loss of information
If only virtual message erasure is implemented, then digital synchronization is achieved, but physical message erasure capability is lost
Solution Approach 1:
The patent combines two erasure mechanisms into one device: a clearing unit that physically contacts the touchpad to erase written messages, and a processing module that generates erasing signals to remove virtual digital messages. This merging allows both physical and virtual message erasure to be performed through a single unified action of touching the touchpad with the stylus
3Adaptability or versatility
If a complex erasing mechanism is added to the stylus, then message erasure functionality is achieved, but the device becomes more complicated
Solution Approach 1:
The stylus utilizes the existing touchpad surface and its sensor capabilities to perform erasure functions. The clearing unit simply needs to contact the touchpad surface, and the processing module leverages the touchpad's existing signal generation ability to create erasing signals, rather than requiring complex independent erasing mechanisms

AI summary
A message erasing device and a message erasing system, and the message erasing system includes a message erasing device and a message receiving device. The message erasing device includes a device body, a processing module, and an erasing module. The device body touches the message receiving device by a clearing unit and erases an actual message of the message receiving device, and the movable unit touches the processing module according to the clearing unit touching the message receiving device, so that the processing module generates an erasing signal to the message receiving device. The message receiving device provides a clear signal to an electronic device according to the erasing signal.
