Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-mode communication device supports simultaneous communications across different protocols (IEEE 802.11 and Bluetooth), then communication versatility is improved, but device complexity increases
Solution Approach 1:
The patent implements a multi-mode communication device that can simultaneously support multiple communication protocols (IEEE 802.11 for WLAN and Bluetooth for PAN) within a single device. The device includes separate communication modules for each protocol, allowing it to perform multiple communication functions concurrently, thereby achieving versatility while managing complexity through modular design.
2Length of moving object
If personal area network communications are used for very short distance communications, then communication simplicity is maintained, but transmission distance is limited
Solution Approach 1:
The patent combines different communication protocols (IEEE 802.11 for long-distance WLAN communication and Bluetooth for short-distance PAN communication) into a single multi-mode device. This merging allows the device to leverage the short-distance advantage of PAN protocols for nearby communications while using WLAN protocols for extended range, effectively extending overall transmission distance without requiring a single complex protocol.
3Reliability
If encryption techniques are employed to securely transmit data, then communication security is improved, but processing time increases
Solution Approach 1:
The patent implements encryption mechanisms that operate in advance of data transmission, establishing secure communication channels before actual data transfer. The encryption is applied at the protocol level, where security operations are performed on data structures before they are transmitted, allowing secure transmission without significant delays to the overall communication process.

AI summary
An integrated circuit radio transceiver and associated method comprises a multi-mode device operable to support personal area network communications as well as traditional wireless local area network communications. In one embodiment, IEEE 802.11 protocol IBSS communications are used to transport Bluetooth communication data packets. Thus, the multi-mode device is operable to establish traditional BSS communications with an Access Point in addition to establishing peer-to-peer communications with another multi-mode device to transport the Bluetooth communications over the 802.11 IBSS communication link.
