Solution Overview

Problem

Conventional methods for pairing processor-based mobile devices with touch screen devices in public locations are complex, require specific wireless networking capabilities, and involve tedious manual operations, making them not intuitive or quick enough for users.

Innovation Solution

The system pairs mobile devices with touch screen devices by detecting a physical contact and matching the orientation of the mobile device with the touch screen device, using sensors to coordinate user actions and initiate pairing without the need for complex manual inputs or specific wireless capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional pairing methods (QR codes, PIN entries, NFC, Bluetooth) are used, then pairing capability is achieved, but device complexity and ease of operation deteriorate due to requiring specific wireless networking capabilities and tedious manual operations

Engineering Contradiction:
Improvepairing operation simplicityVSAvoidwireless networking capabilities requirement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the pairing initiation function from complex wireless communication protocols and implements it through basic sensor detection (accelerometer, gyroscope, touch sensor). The core pairing trigger is separated from the need for Bluetooth, NFC, or QR code scanning capabilities, allowing pairing to be initiated through simple physical actions like placing the device on a surface or rotating it to a specific orientation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system enables self-service pairing by automatically detecting device orientation and physical contact through onboard sensors, then autonomously initiating the pairing process without requiring manual user input. The device monitors its own sensor data and automatically determines when pairing conditions are met, eliminating the need for users to manually scan codes or enter PINs.

Inventive Principle:
Principle #25Self-service

2Productivity

If conventional pairing methods are used, then pairing functionality is achieved, but loss of time increases due to tedious manual operations

Engineering Contradiction:
Improvepairing speedVSAvoidmanual operation time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by continuously monitoring device orientation and physical contact conditions through sensors before pairing is actually needed. The system is already tracking accelerometer, gyroscope, and touch sensor data in real-time, so when the user simply places or rotates the device, the pairing conditions are immediately recognized and the process starts without any additional user steps or waiting time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent skips the traditional multi-step pairing process (scanning, selecting, confirming, entering PINs) and rushes directly to pairing initiation through sensor-based detection. By using physical actions like device rotation or placement as the trigger, the system bypasses intermediate manual operations and moves quickly from user action to pairing establishment.

Inventive Principle:
Principle #21Skipping (Rushing through)

3Ease of operation

If orientation-based pairing is implemented, then ease of operation improves through intuitive user actions, but device complexity increases due to sensor coordination requirements

Engineering Contradiction:
Improveintuitive user action recognitionVSAvoidsensor coordination system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies universality by using the device's existing sensor system (accelerometer, gyroscope, touch sensors) for multiple purposes: not only for motion tracking and display orientation but also for pairing initiation detection. These sensors already exist in modern devices for other functions, and the patent extends their utility to include pairing triggers, avoiding the need for dedicated pairing hardware.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses sensor data as an intermediary between the user's physical action and the pairing process. Instead of direct user input like button presses or code scanning, the system mediates through sensor detection of orientation and contact, translating physical movements into pairing triggers. This intermediary layer simplifies user interaction while managing the complexity of sensor coordination internally.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Systems and methods are provided for pairing a mobile device with a second device based on the mobile device being placed flat against a touch screen of the second device. The mobile device determines that is has been placed in a predetermined orientation that matches the orientation of the display of the second device. The second device detects the contact of the mobile device with its touch screen. Both devices send timestamps of their respective determinations to a server that compares the timestamps. If the timestamps match within a predetermined threshold, the server initiates pairing of the devices.
