Wireless Communication Device Search Effort Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication devices face high power consumption and inefficiency when searching for and connecting to multiple devices, limiting their ability to handle a large number of connections effectively.
Innovation Solution
The communication device controls its search effort based on the relevance of previously connected or paired devices and communication protocols, optimizing power usage by prioritizing frequently used devices and protocols, thereby reducing power consumption and increasing the number of devices that can be handled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a round-robin search is performed for all known devices, then all devices can be found, but power consumption increases and connection time increases
Solution Approach 1:
The patent applies local quality by assigning different search efforts to different devices based on their individual relevance to the communication device. Frequently used devices receive higher search effort (lower search thresholds) while less important devices receive lower search effort (higher search thresholds), optimizing the balance between connectivity versatility and power consumption
Solution Approach 2:
The patent changes the search threshold parameter dynamically based on device relevance. The search threshold for each device is adjusted according to usage frequency and recency, allowing the system to adapt search parameters to match actual connectivity needs rather than using a uniform threshold for all devices
2Adaptability or versatility
If a round-robin search is performed for all known devices, then all devices can be found, but average connection time increases
Solution Approach 1:
The patent applies local quality by assigning different search efforts to different devices based on their individual relevance to the communication device. Frequently used devices receive higher search effort (lower search thresholds) while less important devices receive lower search effort (higher search thresholds), optimizing the balance between connectivity versatility and power consumption
Solution Approach 2:
The patent performs preliminary actions by pre-calculating and storing relevance metrics for each device based on historical connection data. This preliminary assessment allows the system to prioritize search efforts for important devices without performing exhaustive searches for all devices, reducing average connection time
3Use of energy by moving object
If search is performed only when not connected to any device, then power consumption is reduced, but the device cannot efficiently handle multiple simultaneous connections
Solution Approach 1:
The patent applies dynamics by making the search behavior adaptive rather than static. The system continuously monitors connection status and dynamically adjusts search activities based on current connectivity state and device relevance, enabling efficient handling of multiple connections while maintaining power efficiency
Solution Approach 2:
The system performs self-service by automatically managing search priorities based on its own usage patterns. The communication device analyzes its own connection history and autonomously determines which devices should receive higher search effort, eliminating the need for manual configuration or exhaustive searches

AI summary
There is provided a method of wirelessly connecting a communication device to other devices using a communication protocol, wherein the communication device searches for external devices known to the communication device by executing a search activity in which the search effort to be spent by the communication device increases with the number of known external devices to be searched, wherein the communication device adjusts the search effort spent on the search activity for each one of the external devices according to the relevance of that external device, with a higher relevance of the external device resulting in a higher search effort, and wherein the search effort is determined by at least one of the following parameters of the search activity: scheduling frequency, duty cycle and transmission power.
