Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional data communication systems are used for touchscreen data transmission, then basic data transfer is achieved, but data transmission efficiency and security are insufficient
Solution Approach 1:
The patent introduces a user's body (specifically the hand or finger) as an intermediary medium for data transmission. The touchscreen display generates electromagnetic signals that couple with the user's body, which then transmits the data wirelessly to a receiving device. This intermediary approach enables both efficient data transfer and enhanced security through biometric authentication, as the user's body characteristics serve as a unique authentication mechanism.
2Reliability
If biometric authentication is implemented for secure communication, then data transmission security is improved, but system complexity increases
Solution Approach 1:
The patent employs the user's own body as the authentication mechanism, eliminating the need for external authentication hardware or complex verification systems. The user's body naturally couples with the electromagnetic signals from the touchscreen, and the receiving device automatically detects the unique biometric characteristics of the user's body to verify authentication. This self-service approach simplifies the overall system while maintaining high security.
3Ease of operation
If touchscreens are integrated with computing devices for seamless user interaction, then ease of operation is improved, but data transmission reliability deteriorates
Solution Approach 1:
The patent replaces traditional mechanical or wired data transmission methods with electromagnetic field-based wireless transmission. The touchscreen display generates electromagnetic signals that couple with the user's body to transmit data wirelessly to a receiving device. This substitution eliminates physical connections and mechanical interfaces, thereby improving ease of operation while maintaining transmission reliability through the use of the user's body as a stable transmission medium.

AI summary
A computing device includes signal generation circuitry and also includes a location on the computing device that is operative to couple a signal generated by the signal generation circuitry into a user. For example, the computing device includes signal generation circuitry that generates a signal that includes information corresponding to a user and/or an application that is operative within the computing device. The signal generation circuitry couples the signal into the user from a location on the computing device based on a bodily portion of the user being in contact with or within sufficient proximity to the location on the computing device that facilitates coupling of the signal into the user. Also, the signal may be coupled via the user to another computing device that includes a touchscreen display that is operative to detect and receive the signal.
