Solution Overview

Problem

Current systems for recreational vehicle navigation lack real-time, three-dimensional data sharing and comparison of vehicle performance, limiting users' ability to replicate routes and adjust based on real-time conditions.

Innovation Solution

A system comprising camera modules, sensors, interface circuitry, and processing circuitry that collects and adjusts vehicle and map data to create a three-dimensional representation, allowing for real-time data sharing and comparison between vehicles, including vehicle speed, GPS coordinates, and external conditions like temperature and air quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If real-time three-dimensional vehicle performance data is collected and shared, then users can compare vehicle performance and make informed route decisions, but system complexity and data processing requirements increase

Engineering Contradiction:
Improvevehicle performance dataVSAvoiddata collection and processing system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines multiple data collection functions (camera modules, sensors, GPS) and data processing tasks into an integrated system. The processing circuitry merges vehicle data, map data, and environmental data into a unified three-dimensional representation, reducing overall system complexity while maintaining comprehensive data collection capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system employs multi-functional components that serve multiple purposes. For example, the camera modules not only capture visual data for three-dimensional representation but also provide environmental context. The sensors collect both vehicle performance metrics and external condition data, eliminating the need for separate dedicated systems for each function.

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

2Measurement precision

If detailed vehicle data and map data are collected for three-dimensional reproduction, then navigation accuracy and route decision-making improve, but data storage and transmission requirements increase

Engineering Contradiction:
Improvevehicle position and performance measurementVSAvoiddata volume
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The system extracts only the essential and relevant data elements needed for three-dimensional vehicle reproduction and performance comparison. Rather than transmitting all raw sensor data, the processing circuitry identifies and extracts key parameters such as vehicle position, speed, orientation, and critical environmental factors, significantly reducing data volume while maintaining measurement precision.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transforms traditional two-dimensional map data and vehicle telemetry into a three-dimensional representation. This dimensional transformation allows the system to convey comprehensive vehicle performance and environmental information more efficiently, as the third dimension enables compact encoding of spatial relationships and vehicle orientation that would otherwise require multiple separate data streams.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If real-time sharing of three-dimensional vehicle reproduction is implemented, then users can observe and compare vehicle performance, but energy consumption and computational load increase

Engineering Contradiction:
Improvereal-time data accuracyVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

Instead of continuous real-time transmission of all vehicle data, the system employs periodic updates at strategically determined intervals. The processing circuitry assesses when significant changes in vehicle performance or environmental conditions occur and triggers data transmission only at these moments, maintaining real-time accuracy while dramatically reducing energy consumption compared to continuous transmission.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system implements selective data transmission, sending only the partial set of data that is most critical for maintaining real-time accuracy. Rather than transmitting complete vehicle state information continuously, the processing circuitry identifies and transmits only the essential parameters that users need for performance comparison and route decision-making, reducing computational load and energy usage.

Inventive Principle:
Principle #16Partial or excessive action
