Solution Overview

Problem

Current pairing processes for wireless peripheral devices in congested environments with multiple candidate host information handling systems are inefficient, prone to security risks, and create distractions due to simultaneous pairing notifications, especially for headless devices lacking input capabilities.

Innovation Solution

A pre-pairing host contention and arbitration module executed by the wireless peripheral device's microcontroller filters out candidate systems based on proximity using RSSI measurements, determining the closest system for secure pairing through proximity beacons and reducing unnecessary pairing notifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the wireless peripheral device broadcasts pairing requests to all candidate host systems in range, then more host systems can potentially pair with the device, but this causes simultaneous pairing notifications that create user distraction and security risks

Engineering Contradiction:

Improvepairing capabilityVSAvoiduser distraction and security risks

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by determining proximity of candidate host systems to the wireless peripheral device before initiating pairing requests. This pre-assessment filters out distant systems that are unlikely to be the intended pairing target, thereby preventing unnecessary pairing notifications and reducing user distraction while maintaining security

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system applies different treatment to different candidate host systems based on their local characteristics - specifically their proximity to the wireless peripheral device. Host systems that are close to the device receive pairing requests, while distant systems do not, creating a localized pairing approach that reduces noise and security risks

Inventive Principle:

Principle #3Local quality

2Productivity

If the wireless peripheral device initiates pairing with multiple host systems simultaneously, then pairing opportunities are maximized, but this increases processing complexity and pairing time

Engineering Contradiction:

Improvepairing efficiencyVSAvoidpairing process complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The pairing process is segmented into distinct phases: first determining proximity of candidate host systems, then selectively initiating pairing requests only with close systems. This segmentation simplifies the overall process by breaking it into manageable steps rather than attempting to manage multiple simultaneous pairings

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary proximity determination before initiating pairing requests, which filters the candidate pool and reduces the number of simultaneous pairing operations needed, thereby reducing processing complexity and time

Inventive Principle:

Principle #10Preliminary action

AI summary

A system and method for pre-pairing arbitration of a wireless peripheral device among a plurality of candidate host information handling systems comprising a hardware microcontroller executing code instructions of a pre-pairing host contention and arbitration module to transmit a first pairing proximity discovery beacon and a second pairing proximity beacon to the candidate host information handling systems, the first pairing proximity beacon having lower signal power than the second pairing proximity beacon, and to transmit an instruction to cease pairing to any candidate host information handling system failing to respond to the first pairing proximity beacon. The proximity distances for remaining candidate host information handling systems are determined based on received signal strength indicator values of the first pairing proximity discovery beacon and the second pairing proximity beacon to select a closest first candidate host information handling system and prompt pairing at that first candidate host information handling system.
