Solution Overview

Problem

Current systems for in-vehicle position detection, such as those used in aircraft, require manual seat selection by passengers, which is inefficient and inconvenient when passengers change seats during transit.

Innovation Solution

A method and system that utilize wireless emitters positioned at known locations within the vehicle to determine the position of a personal device relative to the vehicle's floor plan, automatically associating the device with different seats as the passenger moves, and updating the floor plan accordingly, while also managing and transferring settings for vehicle management components like entertainment and climate control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual seat selection is used, then passengers can control their seat assignments, but the process becomes inefficient and inconvenient when passengers change seats

Engineering Contradiction:
Improveseat selection processVSAvoidtime to reselect seat
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system automatically detects passenger seat changes using wireless emitters and personal devices, eliminating the need for manual reselection. The automatic association between passenger devices and seat locations enables the system to self-update without passenger intervention, resolving the contradiction between ease of operation and time loss.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical process of seat selection with an automated electronic detection system using wireless emitters and personal devices. This substitution eliminates the need for passengers to manually interact with the system when changing seats, significantly reducing the time and effort required.

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

2Extent of automation

If automatic position tracking is implemented, then seat association updates seamlessly, but the system complexity increases

Engineering Contradiction:
Improveautomatic seat associationVSAvoidposition detection system
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The wireless emitters and personal devices serve multiple functions: position detection, seat association, and triggering vehicle management events. This multi-functionality reduces the need for separate dedicated systems, thereby managing complexity while achieving high automation.

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

Solution Approach 2:

The patent uses wireless emitters as intermediary elements positioned at known locations to facilitate position detection. These emitters act as mediators between the physical seat locations and the digital tracking system, simplifying the overall system architecture by providing standardized detection points throughout the vehicle.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If wireless emitters are positioned at known locations, then position detection accuracy improves, but the device complexity and cost increase

Engineering Contradiction:
Improveposition detection accuracyVSAvoidemitter network
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The vehicle space is segmented into discrete zones with wireless emitters positioned at known locations. This segmentation allows the system to determine passenger position by identifying which emitter's signal the personal device is closest to, providing accurate position detection without requiring a continuous complex sensor network.

Inventive Principle:
Principle #1Segmentation
