Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques face difficulties in sharing and updating connection information between information processing devices and display devices, especially when the connection information changes, leading to complex user operations and potential input errors.
Innovation Solution
An information processing system that includes a display device with a wireless communication unit, storage unit, and change unit for updating connection information, and a first information processing device with a wireless reader/writer, acquisition unit, and writing unit to easily acquire and write new connection information to a wireless tag, facilitating seamless sharing and updating of connection information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If connection information is stored in the display device's storage unit, then the display device can maintain connection information, but other information processing devices cannot easily access or share the connection information when it changes
Solution Approach 1:
The patent introduces a wireless tag as an intermediary device between the display device and other information processing devices. The wireless tag stores connection information and can be read by multiple devices, eliminating the need for direct access to the display device's storage unit. This mediator approach enables easy information sharing while keeping the display device's internal structure simple.
Solution Approach 2:
The patent separates the connection information storage function from the display device by using an external wireless tag. This segmentation allows the connection information to be accessed by multiple devices independently of the display device's internal storage structure, simplifying the overall system architecture while improving information accessibility.
2Adaptability or versatility
If the display device has a wireless reader/writer to write connection information in a wireless tag, then connection information can be shared with other devices, but the cost of the display device increases
Solution Approach 1:
The patent enables other information processing devices to perform the writing operation themselves using their own wireless reader/writer functions. Instead of requiring the display device to have writing capability, the system allows client devices to autonomously update the wireless tag with connection information, reducing the display device's hardware requirements and cost.
Solution Approach 2:
Instead of the display device actively pushing connection information to devices or requiring writing capability, the system inverts the approach by allowing devices to passively read and actively write to the wireless tag. This role reversal eliminates the need for expensive writing hardware in the display device while maintaining full functionality.
3Adaptability or versatility
If connection information changes in the display device, then the display device can use updated information, but existing connections to other devices may become invalid or require manual reconfiguration
Solution Approach 1:
The patent stores connection information in advance in the wireless tag, which can be read by multiple devices. When connection information needs to be updated, the change is immediately reflected in the tag, and other devices can automatically pick up the updated information without manual reconfiguration. This preliminary storage approach ensures continuous validity of connection information across all devices.
Solution Approach 2:
The system enables a feedback mechanism where updated connection information in the wireless tag is automatically detected and adopted by other information processing devices. This feedback loop ensures that all devices automatically synchronize with the latest connection information without requiring manual intervention, maintaining ease of operation during updates.

AI summary
A display device includes: a first wireless communication unit which performs wireless communication in a first format with an external device; a storage unit which stores connection information used in the wireless communication in the first format; a change unit which changes the connection information stored in the storage unit; and a display unit which displays an image received via the first wireless communication unit from the external device. A first information processing device includes: a wireless reader/writer which performs wireless communication in a second format in order to read information from or write information in a wireless tag; an acquisition unit which acquires the changed connection information; and a writing unit which outputs, to the wireless reader/writer, a signal for writing the connection information acquired by the acquisition unit into a first wireless tag.
