Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If mobile phones use built-in display screens, then portability is maintained, but display capacity is limited
Solution Approach 1:
The patent transitions the display function from the mobile phone's internal display to an external display device, effectively moving the display capacity to another dimension (external space). The mobile phone connects to external displays via RFID technology, allowing the phone to leverage the larger screen real estate of external devices while maintaining its own compact form factor.
2Quantity of substance
If mobile phones connect to external display devices, then display capability is enhanced, but connection complexity increases
Solution Approach 1:
The RFID tag embedded in the external display device automatically provides configuration information to the mobile phone when detected. This self-service mechanism eliminates the need for manual configuration steps, allowing the mobile phone to automatically obtain and apply the necessary connection parameters, thereby reducing connection complexity while enhancing display capability.
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 mobile devices to utilize external display devices with greater capacity, effectively enhancing the display capabilities of mobile phones and handheld devices by transmitting and regenerating images on larger, higher-resolution screens.
Implementation Method 1
Radio Frequency Identification (RFID) is an electronic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. An RFID tag is a small object that can be attached to or incorporated into a device. RFID tags contain silicon microchips and antennas to enable the tags to receive and respond to Radio-Frequency (RF) queries from an RFID transmitter-receiver (transceiver).
Data Source
AI summary
A method and system for providing enhanced display capability for mobile phones and handheld devices, such as Personal Digital Assistants (PDAs), when such devices are within range of external display devices equipped with Radio Frequency Identification (RFID) tags and display data receivers. The mobile phone searches for RFID tag-equipped external display devices, and upon locating such a device sends a request to the external device for connection and configuration information. Once the connection and configuration information from the external display device is received by the mobile phone or handheld device, a process of automatic synchronization between the mobile phone and the external display device occurs. The output images of the mobile phone are then transmitted to the external display device, which includes the functionality or mechanisms to receive and regenerate the output images.
