Solution Overview

Problem

Existing peer-to-peer communication devices face difficulties in initiating connections due to the lack of a straightforward method for users to pair devices, often resulting in confusion and errors, especially in crowded environments where similar or identical device names are common.

Innovation Solution

The method involves using sensors to detect shared physical experiences, such as non-radio signals or touch screen swipes, to generate and compare local and remote data, allowing communication devices to pair securely and intuitively based on correlated physical characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users select from arbitrary device names to initiate peer-to-peer communication, then devices can be paired, but the process becomes confusing and laborious

Engineering Contradiction:
Improvepairing accuracyVSAvoidpairing process simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical/manual selection process with an automatic sensor-based detection system. Instead of users manually scanning and selecting from lists of device names, the system uses sensors (optical, acoustic, vibrational) to automatically detect and recognize shared physical experiences, substituting the manual mechanical interaction with an automated sensing mechanism that eliminates confusion and labor.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables devices to pair themselves automatically by detecting shared physical experiences in their environment. Rather than requiring user intervention to initiate pairing, the devices autonomously sense their surroundings, compare sensor data, and establish connections based on correlated physical characteristics, making the pairing process self-service and intuitive.

Inventive Principle:
Principle #25Self-service

2Productivity

If devices use arbitrary names for pairing, then connection initiation is possible, but errors increase in crowded environments

Engineering Contradiction:
Improvepairing speedVSAvoidpairing accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where devices continuously sense their physical environment and compare sensor readings in real-time. When devices experience correlated physical phenomena (such as being near each other in space or detecting the same acoustic signal), this feedback loop enables automatic identification and confirmation of the correct device to pair with, eliminating errors that occur with arbitrary names in crowded environments.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system changes the pairing parameter from arbitrary textual names to physical characteristics detectable by sensors. Instead of relying on user-selectable names that can be identical or similar, the system uses measurable physical parameters (optical signals, acoustic waves, vibrational patterns) that naturally differentiate devices based on their actual physical state and position, thereby improving both speed and accuracy of pairing.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If manual name selection is used for pairing, then devices can connect, but user experience deteriorates

Engineering Contradiction:
Improvepairing mechanism simplicityVSAvoiduser interaction requirement
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent extracts the pairing function from the complex manual name-selection interface and implements it through simple sensor detection. By taking out the pairing mechanism from the traditional name-based system, the invention enables devices to automatically identify and connect based on shared physical experiences, dramatically reducing user interaction requirements while simplifying the overall user experience.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Apparatus and methods for pairing communication devices are disclosed. An exemplary apparatus includes at least one sensor to produce a data signal responsive to sensing physical characteristics of an environment of the communication device, and a capture component to capture portions of the data signal to generate local data indicative of the physical characteristics. A peer interface component receives, via the wireless transceiver, remote data from at least one other communication device that is indicative of physical characteristics of an environment of the other communication device. A data correlation component compares the local data with the remote data and initiates, when the comparison indicates the communication device and the other communication device are sensing the same physical characteristics, a pairing of the communication device with the other communication devices.
