Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical connection is used for docking, then connection reliability is improved, but device versatility and usage environment are limited
Solution Approach 1:
The patent replaces the mechanical connection system (physical docking ports and cables) with a wireless communication system. The portable device and docking center establish connections through Wi-Fi direct peer-to-peer communication, eliminating the need for physical connectors while maintaining functional reliability for audio and display operations.
Solution Approach 2:
The patent introduces a docking center as an intermediary device that facilitates wireless connections between portable devices and external peripherals. The docking center acts as a mediator that manages Wi-Fi direct connections, handles docking protocols, and coordinates communication between the portable device and connected peripherals without requiring direct physical connections.
2Stability of the object's composition
If physical connection is required for docking, then connection stability is improved, but application coverage is limited
Solution Approach 1:
The patent implements a universal wireless docking protocol that enables multiple functions through a single docking center. The system supports audio playback, display output, file transfer, and peripheral connections through standardized Wi-Fi direct communication protocols, allowing one docking center to serve multiple purposes without requiring different physical connectors for each function.
Solution Approach 2:
The patent changes the connection parameter from physical presence to wireless signal-based connection. By using Wi-Fi direct technology, the system maintains connection stability through protocol-based communication while enabling broader application coverage. The docking protocol dynamically establishes and manages connections based on service requirements rather than fixed physical interfaces.
3Adaptability or versatility
If wireless connection is used for docking, then usage environment is expanded, but connection reliability may be compromised
Solution Approach 1:
The patent implements feedback mechanisms in the wireless docking protocol to monitor and maintain connection quality. The docking center and portable device exchange status information and can dynamically adjust connection parameters based on signal strength and service requirements, ensuring reliable operation despite the wireless medium's inherent variability.
Solution Approach 2:
The patent performs preliminary actions during the docking discovery and pairing phases to establish reliable wireless connections before actual service begins. The system exchanges capability information, negotiates connection parameters, and establishes secure Wi-Fi direct connections in advance, ensuring reliability is prepared before the actual docking service starts.
Data Source
AI summary
A method for performing a docking service using Wi-Fi by a wireless dockee (WD), includes transmitting a probe request including a docking information element (IE) 1 for discovering to docking service to a wireless docking center (WDC); receiving a probe response including a docking IE 2 from the wireless docking center (WDC) which has received the probe request; and performing a docking connection with the wireless docking center (WDC) based on the received probe response, wherein the docking IE 1 includes at least one of a device name parameter indicating a name of a device, a device Identifier parameter for identifying a device, or a docking information request parameter indicating a command of a docking service discovery.
