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

VSEngineering 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

Engineering Contradiction:
Improveconnection method compatibilityVSAvoidradio interference
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improveconnection flexibilityVSAvoidcommunication stability
Core Design Contradiction:
Ease of operationVSReliability

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improveconnection capacityVSAvoidradio interference
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

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.

Inventive Principle:
Principle #15Dynamics
