Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal device captures pictures of external devices and retrieves their data, then user interface capability and information accessibility are improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent employs an image recognition system as an intermediary that automatically identifies external devices in captured pictures and retrieves their data. This mediator handles the complex tasks of image analysis, device identification, and data correlation, allowing the terminal device to provide enhanced user interface capabilities without directly managing the complexity of device communication and data processing.
Solution Approach 2:
The system performs preliminary actions by pre-processing and storing data from external devices before they are needed. When a picture is captured, the device already has access to pre-retrieved information about external devices, enabling rapid display and interaction without real-time processing delays. This preliminary data preparation reduces the computational burden during actual user interaction.
2Loss of information
If the terminal device detects and displays information from multiple external devices, then information completeness is improved, but processing time and computational resources increase
Solution Approach 1:
The patent extracts only the essential and relevant information from external devices based on their types and user needs. Rather than processing and displaying all available data from every external device, the system selectively extracts key attributes such as device identity, location, and relevant status information, thereby maintaining information completeness while significantly reducing processing time and computational resources.
Solution Approach 2:
The system applies local quality by tailoring the amount and type of information retrieved from each external device according to its specific characteristics and the context. Different external devices provide different levels of detail based on their capabilities and relevance, allowing the terminal device to optimize processing efficiency while maintaining appropriate information completeness for each device type.
Data Source
AI summary
A terminal device, an information display system and a method of controlling the terminal device are disclosed. The terminal device includes a camera unit configured to capture a picture in which an external device connected with a network is included, a control unit configured to detect the external device from the captured picture, a communication unit configured to transmit and receive data and a display unit configured to display the captured picture. If the detected external device in the captured picture is selected, the control unit controls the communication unit to receive information on the external device based on a sensing history of the external device and can control the display unit to display the received information on the external device on the display unit.
