Remote Vehicle Diagnostics Using VIN and VEC File Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Advanced vehicle diagnostic systems are designed for local use by technicians and require significant memory storage, making them unsuitable for real-time remote diagnostics and inaccessible to average drivers due to their complexity and memory requirements.
Innovation Solution
A vehicle diagnostic system that uses a vehicle identification number (VIN) to remotely obtain diagnostic status information and perform output controls through a host device connected to the vehicle, utilizing a vehicle electronic configuration (VEC) file to facilitate access to vehicle control modules, with stored instructions that operate within low memory constraints, enabling remote communication and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If advanced vehicle diagnostic systems are implemented with large database subscriptions stored on local computers, then diagnostic analysis capability is improved, but memory storage requirements increase and real-time remote diagnostics become prohibitive
Solution Approach 1:
The patent introduces a remote server as an intermediary that hosts the large diagnostic databases. The local diagnostic tool no longer needs to store complete database subscriptions, instead accessing only necessary data through the server. This mediator architecture enables comprehensive diagnostic analysis while dramatically reducing local memory requirements.
Solution Approach 2:
The patent transitions the storage dimension from local (device-based) to remote (cloud-based). By moving database subscriptions from the local computer's memory to a remote server's storage infrastructure, the system achieves both high diagnostic capability and low local memory footprint, effectively adding a spatial dimension to data storage.
2Measurement precision
If diagnostic systems are configured for local use with sophisticated analysis capabilities, then diagnostic depth is improved, but accessibility to average drivers deteriorates due to complexity
Solution Approach 1:
The remote server acts as an intelligent intermediary that handles complex diagnostic analysis. The local tool can remain simple and user-friendly while the server performs sophisticated data interpretation. This separates the complexity of analysis from the simplicity of operation, making advanced diagnostics accessible to non-experts.
Solution Approach 2:
The patent enables multiple instances of the diagnostic tool to access the same remote database subscriptions simultaneously. Each user gets a copy of the tool interface but shares the backend analytical resources, allowing average drivers to use simplified interfaces while still benefiting from expert-level diagnostic depth through the shared server infrastructure.
3Loss of information
If large database subscriptions are stored locally for comprehensive vehicle diagnostics, then diagnostic information completeness is improved, but real-time remote access and control capability deteriorates
Solution Approach 1:
The patent shifts data storage from a single local dimension to a distributed architecture spanning local devices and remote servers. This dimensional transition enables simultaneous local processing (for speed) and remote access (for completeness), achieving both real-time responsiveness and comprehensive diagnostic information availability.
Solution Approach 2:
The remote server provides universal access to diagnostic databases for multiple users and devices simultaneously. It serves as a centralized resource that enables both local real-time diagnostics and remote access control functions, making the system multi-functional and eliminating the trade-off between information completeness and remote capability.
