Solution Overview

Problem

Existing electronic device pairing methods often require manual user intervention and suffer from latency issues, leading to unintended device control and setting conflicts when switching between different computing devices.

Innovation Solution

A computing device transmits a first identifier quickly to establish a preliminary pairing, followed by a second, more detailed identifier to confirm the correct device, reducing latency and ensuring accurate pairing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single detailed identifier is transmitted for device pairing, then pairing reliability is improved, but pairing time increases due to transmission latency

Engineering Contradiction:
Improvepairing reliabilityVSAvoidpairing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The identifier transmission is segmented into two phases: a first identifier transmitted during a first time frame for quick preliminary pairing, and a second identifier transmitted during a second time frame for confirmation. This segmentation allows the system to achieve both fast initial pairing and reliable verification without requiring the complete second identifier to be transmitted before pairing can begin.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If manual user intervention is required for device pairing, then pairing accuracy is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvepairing accuracyVSAvoidease of pairing
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The pairing system performs self-verification by comparing the first identifier received during the first time frame with the second identifier received during the second time frame. This automatic verification process eliminates the need for manual user intervention to confirm pairing accuracy, as the system independently validates that the correct device has been paired through identifier matching.

Inventive Principle:
Principle #25Self-service

AI summary

A computing device comprises a logic subsystem and a storage subsystem holding instructions executable by the logic subsystem to transmit a first identifier of the computing device to a separate electronic device, the first identifier being transmitted during one time frame of a plurality of sequential time frames. A second identifier of the computing device is transmitted to the electronic device, the second identifier including more data than the first identifier, the second identifier being transmitted over two or more time frames of the plurality of sequential time frames. An electronic pairing is established between the computing device and the electronic device based at least in part on one or both of the first and second identifiers, the electronic pairing enabling receiving of control inputs from the electronic device at the computing device.
