Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If one-to-one communication is used between two appliances, then partner specification is simple, but one-to-many wireless communication cannot be performed efficiently
Solution Approach 1:
The communication process is segmented into two distinct phases: first, a pairing phase using short-range communication (infrared) to establish trusted relationships and exchange identifying information between pairs of appliances; second, a data communication phase using wireless LAN where appliances can communicate with multiple partners simultaneously. This segmentation allows the system to achieve one-to-many communication capability while keeping the initial pairing process manageable through sequential one-to-one interactions.
Solution Approach 2:
The patent performs preliminary pairing and identifying information exchange through short-range communication before the actual wireless LAN data transmission. By pre-establishing trusted relationships and collecting identifying information in advance, the system prepares the necessary foundation for efficient one-to-many communication, reducing the complexity during the actual data transmission phase.
2Area of stationary object
If wireless LAN is used for communication, then coverage area is extended, but identifying information specification becomes necessary and complex
Solution Approach 1:
The patent introduces short-range communication (infrared) as an intermediary mechanism that operates before wireless LAN communication. This intermediary step establishes trusted relationships and exchanges identifying information in a controlled, secure manner. Once this preliminary pairing is complete, the wireless LAN can operate with extended coverage without requiring complex real-time partner specification, as the identifying information has already been established through the intermediary short-range communication phase.
3Productivity
If multiple appliances communicate simultaneously, then communication efficiency increases, but the number of pairing processes increases
Solution Approach 1:
The communication process is divided into a pairing phase and a data transmission phase. During the pairing phase, appliances perform sequential one-to-one pairings using short-range communication, which is time-consuming but necessary for security. Once pairing is complete, the system transitions to the data transmission phase using wireless LAN, where multiple appliances can communicate simultaneously with high efficiency. This segmentation concentrates the time loss in the initial pairing phase while maximizing productivity during the subsequent data transmission phase.
Solution Approach 2:
The patent performs all necessary pairing and identifying information exchange as preliminary actions before bulk data communication begins. By completing the time-consuming pairing processes in advance through short-range communication, the system eliminates the need for repeated pairing during subsequent wireless LAN communication, thereby achieving high communication efficiency without repeatedly incurring pairing processing time.

AI summary
Each game apparatus participating in a network system has a wireless communication module for performing a one-to-many wireless communication with reference to identifying information and a local communication module for performing a one-to-one infrared communication without referring to it. In a case that the one-to-many wireless communication is performed, pairing processing is executed in a tournament method such that a master and a slave are first decided between its own game apparatus and any one of the game apparatuses over the local communication module, and identifying information stored on the slave side is collected into the master side. In a case that its own game apparatus becomes the only master game apparatus as a result of a series of pairing processing, it transmits a signal including identifying information of all the game apparatuses over the wireless communication module whereas in a case that its own game apparatus becomes the slave apparatus, it receives the signal.
