Vehicle Analysis Interface Using WebAssembly Data Mirroring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle testing methods require additional hardware and communication interfaces to separate the application or system under test from the environment, leading to increased hardware costs and performance demands.
Innovation Solution
An assembly utilizing a Web Assembly Interface Type (WIT) to facilitate data transmission and analysis between entities within a vehicle system, allowing for decoupled communication and data filtering/transforming without the need for additional hardware or interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated hardware and communication interfaces are added to separate the system under test from the environment, then system analysis capability is improved, but device complexity and hardware costs increase
Solution Approach 1:
The patent creates a virtual copy of the communication interface using WebAssembly that mirrors the functionality of dedicated hardware interfaces. The WIT-defined interface replicates data transmission and reception capabilities software-based, eliminating the need for physical hardware copies while maintaining system analysis functionality.
Solution Approach 2:
The patent replaces mechanical/hardware communication interfaces with a software-based WebAssembly interface. The WIT-defined communication mechanism substitutes physical data buses and hardware protocols with standardized web technologies, transforming the system from hardware-dependent to software-based communication.
2Reliability
If additional hardware components are added for system testing, then data transmission capability is improved, but loss of substance increases
Solution Approach 1:
The WebAssembly interface defined by WIT serves multiple functions simultaneously: it acts as a communication interface for data transmission, a testing mechanism for system analysis, and a standardized protocol layer. This multi-functionality eliminates the need for separate dedicated hardware components for each function, reducing overall hardware resource consumption.
3Adaptability or versatility
If a vehicle level concept for distributing input data is developed and deployed, then system integration is improved, but device complexity and switch hardware increase
Solution Approach 1:
The patent introduces a new dimensional layer for data distribution using WebAssembly that operates above the traditional hardware switch layer. The WIT-defined interface creates a virtual data distribution network that can route information across the vehicle system without requiring physical switch hardware, adding a software dimension to the data flow architecture.
