Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If NFC technology is used for device communication, then wireless communication capability is improved, but device size increases due to additional proximity card readers
Solution Approach 1:
The touch panel's existing electrodes and driver IC are made to serve dual purposes: traditional touch sensing and wireless communication. The driving electrodes and sensing electrodes that originally formed capacitance structures for touch detection are now also used as sending and receiving electrodes for near field communication, eliminating the need for separate NFC hardware components.
Solution Approach 2:
The patent merges the touch panel's electrical components with the communication function. The same physical structure (electrodes on the board) performs both touch detection and wireless signal transmission/reception, combining two functions into a single integrated component to reduce device complexity and size.
2Loss of information
If traditional data sharing methods are used between devices, then data can be shared, but complex operations are required and user convenience deteriorates
Solution Approach 1:
The system pre-configures the touch panel electrodes to dual-purpose functionality before use. The driving electrodes and sensing electrodes are pre-programmed to serve both touch detection and communication purposes, so when a user brings devices close together, the system automatically initiates the appropriate function based on proximity detection without requiring manual configuration.
Solution Approach 2:
The system automatically detects when another device is in proximity and initiates the data sharing process without requiring complex user input. The touch panel's capacitance structure naturally detects the presence of another device's electrode, and the system self-manages the connection establishment and data transmission based on this detection.
3Adaptability or versatility
If additional proximity card readers are added to enable NFC functionality, then communication capability is improved, but device layout and element arrangement become limited
Solution Approach 1:
The touch panel's existing electrodes and driver IC are made to serve dual purposes: traditional touch sensing and wireless communication. The driving electrodes and sensing electrodes that originally formed capacitance structures for touch detection are now also used as sending and receiving electrodes for near field communication, eliminating the need for separate NFC hardware components.

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables rapid and efficient sharing of applications and files between devices by establishing a touch link based on physical proximity, allowing simultaneous or individual display of applications and files on receiving devices, reducing the need for complex operations and additional hardware.
Implementation Method 1
The touch panel can be the touch panel without a display function, such as the touch pad, or with a display function, such as a touch screen. The touch sensor includes driving electrodes and sensing electrodes set on the board set of the board for forming the capacitance structure. At least one of the driving electrodes and the sensing electrodes is used as the sending electrode, and at least one is used as the receiving electrode. Thus, the signal can be sent and received by the existing electrodes and driver IC of the touch panel device for achieving the touch transmission based on the electric field
