Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the in-vehicle information communication apparatus forms a scatter network with a mobile communication apparatus operating as a master communication apparatus, then the apparatus can participate in Bluetooth communication, but it cannot acquire sensing information from sensing devices without additional pairing operations
Solution Approach 1:
The mobile communication apparatus serves as an intermediary device between the in-vehicle information communication apparatus and the sensing devices. It establishes a proxy relationship where the mobile apparatus can access sensing information from devices in its piconet and forward this information to the in-vehicle apparatus, eliminating the need for the in-vehicle apparatus to directly pair with each sensing device.
Solution Approach 2:
The mobile communication apparatus performs multiple functions: it operates as a master communication apparatus forming a piconet with sensing devices, simultaneously acts as a peripheral device joining the in-vehicle apparatus's piconet, and functions as a proxy to transmit sensing information between the two networks. This multi-functionality enables seamless scatter network operation without additional pairing.
2Reliability
If the in-vehicle information communication apparatus performs pairing operations with each sensing device, then it can acquire sensing information, but this increases user burden and operation complexity
Solution Approach 1:
The mobile communication apparatus acts as a mediator that centralizes the connection management. Instead of the in-vehicle apparatus performing multiple pairing operations with individual sensing devices, the mobile apparatus maintains connections with sensing devices and provides a unified interface to the in-vehicle apparatus, significantly reducing operational complexity.
Solution Approach 2:
The system enables automatic service establishment where the mobile communication apparatus autonomously manages connections to sensing devices and automatically forwards relevant information to the in-vehicle apparatus without requiring user intervention for each pairing operation.
3Adaptability or versatility
If Bluetooth scatter network function is used for data transmission, then device connectivity is enabled, but there is no standard for bridge/routing of data preventing automatic data acquisition
Solution Approach 1:
The mobile communication apparatus implements a software-based routing solution that acts as an intelligent intermediary. It receives data from sensing devices in its piconet, processes and forwards relevant information to the in-vehicle apparatus through the scatter network connection, effectively creating a bridge without requiring changes to Bluetooth hardware standards.
Solution Approach 2:
The invention changes the operational parameters of Bluetooth communication by utilizing the mobile apparatus's dual role in two different piconets. By changing how data flows through the scatter network - using the mobile apparatus as a data relay point - the system achieves automatic data acquisition functionality despite the lack of standardized bridge/routing protocols.

AI summary
A communication apparatus capable of functioning as a central device and being connected to a first piconet and capable of functioning as a peripheral device and being connected to a second piconet using a communication method complying with a Bluetooth standard, receives, from a first device functioning as the peripheral device on the first piconet, information for identifying a service supported by the first device and data associated with the service, and transmits the information for identifying the service to a second device functioning as the central device on the second piconet.
