Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle-based systems for reducing motion sickness during digital content viewing require high bandwidth for transmitting data-intensive virtual reality scenes, are cumbersome due to wired connections, and are not suitable for all seating positions, particularly front-seat passengers.

Innovation Solution

A system comprising a vehicle control unit that preprocesses sensor data to calculate control variables, which are then wirelessly transmitted to data glasses for generating a virtual 3D scene, reducing the data volume required for transmission and ensuring consistency between visual and vestibular perceptions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If virtual reality scenes are transmitted from the vehicle to the data glasses, then the visual perception consistency is improved, but the bandwidth requirement increases

Engineering Contradiction:

Improvevisual perception consistencyVSAvoiddata transmission volume

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential control variables (acceleration, position, orientation data) from the complete sensor data set, transmitting only these critical parameters to the data glasses rather than the entire virtual reality scene data, thereby reducing bandwidth requirements while maintaining visual perception consistency

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of transmitting pre-rendered virtual reality scenes from the vehicle to the glasses, the patent inverts the approach by having the data glasses generate the virtual reality scenes locally using received control variables, shifting the computational burden from the vehicle system to the wearable device

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If a wired connection is used between the vehicle and data glasses, then the data transmission stability is improved, but the ease of operation deteriorates

Engineering Contradiction:

Improvedata transmission stabilityVSAvoiddevice portability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical wired connection system with a wireless communication system, eliminating physical cables and connectors while maintaining data transmission stability through robust wireless protocols, thereby significantly improving the ease of operation and device portability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If the display unit is positioned for rear-seat passengers, then the motion sickness protection is improved, but the adaptability to different seating positions deteriorates

Engineering Contradiction:

Improvemotion sickness protectionVSAvoidseating position compatibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent makes the system universal by implementing it in wearable data glasses that can be used by any occupant regardless of seating position, replacing the position-specific fixed display unit with a portable device that adapts to the user's head position and orientation, providing motion sickness protection for front-seat, rear-seat, and side-seat passengers equally

Inventive Principle:

Principle #6Universality (Multi-functionality)
