Peripheral Device Discovery Beacon for Wireless Network Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low-power peripheral devices waste resources by responding to unnecessary discovery probes and requests, as they are often visible to other devices with which they are not configured to communicate.
Innovation Solution
A method where peripheral devices broadcast a connection configuration indicating they are not configured for communication, but network devices can determine, based on an associated identifier, that the device is actually configured for communication, allowing targeted communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If peripheral devices broadcast connection configuration indicating they are not configured for communication, then power consumption is reduced, but network devices cannot discover devices they are configured to communicate with
Solution Approach 1:
The patent segments the discovery process into two stages: initial discovery using broadcast connection configuration (power-saving mode), and subsequent identification using device identifiers (full communication mode). This allows devices to remain discoverable while minimizing power consumption by only engaging in full communication when necessary.
Solution Approach 2:
The patent implements preliminary action by having peripheral devices broadcast connection configuration and device identifiers in advance. Network devices can identify configured devices from these broadcasts without requiring the peripheral devices to maintain continuous communication readiness, thus saving power while ensuring discoverability.
2Productivity
If peripheral devices respond to all discovery probes, then all devices can be discovered, but battery power is wasted on unnecessary responses
Solution Approach 1:
The patent applies local quality by making the response behavior specific to each network device based on its identifier. Peripheral devices examine the identifier of each probing network device and respond only to those with matching identifiers, rather than responding uniformly to all probes. This selective response approach improves discovery efficiency for configured devices while conserving battery power.
Solution Approach 2:
The patent implements partial action by having peripheral devices perform only the necessary communication actions. Instead of responding to all discovery probes (excessive action), devices respond only to probes from network devices they are configured to communicate with (partial action), thus avoiding wasted battery power while maintaining effective discovery.
3Adaptability or versatility
If peripheral devices remain visible to all devices, then discoverability is maximized, but resource consumption increases
Solution Approach 1:
The patent implements dynamics by making the visibility and responsiveness of peripheral devices dynamic rather than static. Devices adjust their response behavior based on the identifier of the probing network device, being visible and responsive to configured devices while remaining invisible to others. This dynamic approach maximizes discoverability for intended devices while minimizing resource consumption.
