Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless apparatuses experience radio interference when standing by for connections from information processing apparatuses using different communication methods, leading to unstable communication, video delays, or packet loss.
Innovation Solution
A wireless apparatus that includes a wireless control unit and a standby control unit, which stands by for both peer-to-peer (P2P) and infrastructure connections from an information processing apparatus and stops standing by for P2P connections when performing an infrastructure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wireless apparatus stands by for both P2P connection and infrastructure connection simultaneously, then the adaptability and versatility of the wireless apparatus is improved, but radio interference occurs between different communication methods
Solution Approach 1:
The patent implements dynamic switching of standby modes based on current connection state. When an infrastructure connection is established, the apparatus dynamically stops standing by for P2P connections. Conversely, when a P2P connection is active, it stops standing by for infrastructure connections. This dynamic adjustment eliminates radio interference while preserving the capability to support multiple connection types when needed.
2Ease of operation
If the wireless apparatus supports multiple communication methods, then the ease of operation is improved, but communication stability deteriorates due to radio interference
Solution Approach 1:
The system dynamically adjusts its operational state by enabling or disabling standby for specific connection types based on what is currently active. This ensures that only one communication method stands by at a time, preventing radio interference and maintaining communication stability while still offering users flexibility to choose different connection methods as needed.
3Productivity
If the wireless apparatus stands by for connections from multiple information processing apparatuses, then the productivity is improved, but radio interference increases causing video delays and packet loss
Solution Approach 1:
The patent implements dynamic standby control where the wireless apparatus monitors its current connection state and adjusts which connection types it stands by for. When an infrastructure connection is active, it stops standing by for P2P connections, and vice versa. This dynamic approach allows the system to maintain high connection capacity when needed while preventing radio interference that would cause video delays and packet loss.

AI summary
A wireless apparatus (20) is wirelessly communicable with an information processing apparatus (40) and includes a wireless control unit (27) and a standby control unit (24). The wireless control unit (27) stands by for both a peer-to-peer (P2P) connection and an infrastructure connection from the information processing apparatus (40). The standby control unit (24) causes the wireless control unit (27) to stop standing by for the P2P connection when the wireless control unit (27) is performing the infrastructure connection with the information processing apparatus (40).
