Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth interface is used for wireless communication, then device compatibility and ease of operation are improved, but data transmission speed deteriorates
Solution Approach 1:
The patent combines Bluetooth interface and 60 GHz interface into a unified wireless communication system. The Bluetooth component handles device pairing, connection management, and control signaling, while the 60 GHz component handles high-speed data transmission. This merging allows the system to leverage the ease of operation of Bluetooth with the high speed of 60 GHz, resolving the contradiction between compatibility and transmission speed.
2Ease of manufacture
If Bluetooth protocol is used for data transmission, then simplicity of implementation is improved, but productivity deteriorates
Solution Approach 1:
The patent segments the data transmission function into two parts: control signaling through Bluetooth and high-speed data transfer through 60 GHz interface. The Bluetooth protocol stack is used for connection establishment and management, while a separate 60 GHz physical layer handles bulk data transmission. This segmentation allows each component to be optimized for its specific function, maintaining implementation simplicity while achieving high productivity.
Solution Approach 2:
The system implements multi-functionality by using Bluetooth for multiple purposes (device discovery, pairing, control signaling) while dedicating the 60 GHz interface specifically for high-speed data transmission. This universal approach allows the Bluetooth component to maintain simplicity for control functions while the 60 GHz component provides the necessary productivity for data-intensive applications.
3Speed
If high frequency 60 GHz interface is added for high speed transmission, then data transmission speed is improved, but device complexity increases
Solution Approach 1:
The patent introduces a protocol adaptation layer as an intermediary between the Bluetooth stack and the 60 GHz physical layer. This intermediary handles the complexity of coordinating between the two interfaces, managing connection establishment, and translating control signals. By placing this intermediary layer, the system achieves high-speed transmission through 60 GHz while shielding the upper layers from the complexity of dual-interface management.

AI summary
Wireless devices may utilize a communication stack to setup a data transmission session with other devices. The data transmission session may include a physical layer that permits wireless devices to perform operations such as discovery, pairing, and security setup. When a radio interface of a wireless device is insufficient to enable performing a data communication, a data transmission session may be established with at least one of a plurality of other physical layers to accommodate the data communication.
