Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple discovery modes are supported for different applications, then device compatibility and networking flexibility are improved, but device complexity and power consumption increase
Solution Approach 1:
The patent segments the discovery process by creating separate profiles for different applications, each profile containing specific discovery mode properties (push mode, pull mode, autonomous, network assisted) tailored to that application's needs. This segmentation allows each application to operate with its optimal discovery mode without affecting others, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The patent implements preliminary action by pre-configuring multiple discovery mode profiles before runtime. Each profile is prepared with specific discovery mode properties and device type properties in advance, allowing the system to quickly switch between modes based on application requirements without complex real-time decision-making, thus reducing operational complexity while maintaining adaptability.
2Speed
If device discovery is performed continuously to improve connection speed, then networking efficiency is improved, but power consumption increases
Solution Approach 1:
The patent applies periodic action by implementing discovery modes that can be activated only when needed rather than continuous operation. The system periodically checks for available devices based on the selected discovery mode properties, allowing the device to enter low-power states between discovery cycles, thus balancing discovery speed with power consumption.
Solution Approach 2:
The patent implements dynamics by making the discovery process adaptive - the system dynamically selects which discovery mode to use based on current application requirements and environmental conditions. This dynamic approach allows the device to intensify discovery efforts when connections are urgently needed while conserving power during periods when connections are less critical, resolving the speed-power consumption contradiction.

AI summary
A wireless communication device is configured to store a plurality of profiles associated with applications. Each profile includes at least a discovery mode property and a device type property. In response to an application being activated, the wireless device enables a discovery mode for performing discovery in accordance with the discovery mode property retrieved from a selected profile associated with the application. When one or more devices are available for discovery, the wireless device receives information from each device, filters the received information to provide filtered information associated with one or more devices having a device type that matches the device type property, and provides the filtered information to the application. The wireless device may then establish, in accordance with one or more properties retrieved from the selected profile, a Wi-Fi P2P wireless network connection with at least one of the devices. Different profiles may be enabled concurrently, where discovery in relation to both profiles is performed at the same time.
