Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex pairing processes are used for portable devices with tracking systems, then pairing reliability is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvepairing reliabilityVSAvoidease of pairing

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system enables self-service pairing by having the portable device autonomously generate motion gestures and the tracking system automatically recognize and verify these gestures against pre-stored patterns, eliminating the need for manual configuration or complex user intervention while maintaining secure authentication

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces traditional manual pairing mechanisms (button presses, code entry) with motion-based gesture recognition, where the portable device's physical movements are captured by the tracking system and compared against stored gesture patterns to establish authentication

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If gesture data processing includes all three dimensions, then measurement precision is improved, but device complexity increases

Engineering Contradiction:

Improvegesture recognition precisionVSAvoiddata processing complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system extracts and processes only the relevant spatial components of gesture data by comparing motion patterns in the horizontal plane while deliberately minimizing or excluding vertical Z-coordinate motions, reducing processing complexity while maintaining accurate gesture recognition for pairing authentication

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

In embodiments of portable device pairing with a tracking system, a pairing system includes a portable device that generates device acceleration gesture data responsive to a series of motion gestures of the portable device. The pairing system also includes a tracking system that is configured for pairing with the portable device. The tracking system recognizes the series of motion gestures of the portable device and generates tracked object position gesture data. A pairing service can then determine that the series of motion gestures of the portable device corresponds to the series of motion gestures recognized by the tracking system, and communicate a pairing match notification to both the tracking system and the portable device to establish the pairing.
