Innovation Solution

A virtual display arrangement that includes a display device, communication interface, and controller, capable of connecting with remote-controlled vehicles to align and synchronize their navigation based on recorded real-world tracks, adjusting for differences through alignment information and adaptations such as scaling and rotating operations, and enabling seamless transitions between real and virtual worlds using virtual gateways.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If remote-controlled vehicles navigate in different physical locations using separate virtual reality systems, then each user can control their vehicle independently, but the navigation cannot be synchronized and aligned between different locations

Engineering Contradiction:

ImproveAbility to navigate in different physical locationsVSAvoidAlignment and synchronization precision

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent introduces a server as an intermediary that receives track information from multiple virtual display arrangements, performs alignment calculations, and distributes synchronized navigation data back to all users. This mediator enables precise synchronization between different physical locations by centralizing the alignment computation and coordinate system transformation processes.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system transforms navigation parameters by applying coordinate system transformations, scaling factors, and rotation adjustments to align tracks from different physical locations. These parameter changes convert locally-defined track coordinates into a unified global coordinate system, enabling precise alignment and synchronization across distributed locations.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If virtual display arrangements use different recorded real-world tracks, then users can navigate in their own environments, but the tracks cannot be aligned to provide a unified experience

Engineering Contradiction:

ImproveAbility to use local environmentsVSAvoidTrack alignment consistency

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The server applies parameter transformations including scaling, rotation, and translation to recorded track data, converting locally-defined tracks into aligned versions that conform to a common coordinate system. This enables users to navigate their own local environments while maintaining consistent alignment and synchronization across all participants.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

Track alignment and coordinate transformation are performed in advance by the server before navigation begins. The server receives pre-recorded track information, performs alignment calculations, and prepares synchronized navigation data ahead of time, ensuring consistent track alignment without requiring real-time adjustments during navigation.

Inventive Principle:

Principle #10Preliminary action

3Quantity of substance

If remote-controlled vehicles are controlled in different physical locations, then more users can participate, but handling characteristics become inconsistent across locations

Engineering Contradiction:

ImproveNumber of participating usersVSAvoidHandling characteristics consistency

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The system applies parameter transformations to vehicle control inputs and track geometry data, adjusting for differences in physical location characteristics. By transforming coordinates and scaling parameters based on alignment information, the system ensures that handling characteristics remain consistent across different locations, making the navigation experience uniform for all users.
