Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle diagnostic systems require preprogrammed functions or reprogramming to convert raw data into human-understandable values, limiting user flexibility in processing and communicating vehicle diagnostic information.
Innovation Solution
A method that allows users to define mathematical functions without programming languages to process raw data from vehicle engine control units, using user-selected PIDs, scaling factors, offsets, and external functions to derive data, enabling the creation of new data values from multiple sources within a vehicle diagnostic computer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If preprogrammed functions are used for data conversion, then the system maintains simplicity and reliability, but user flexibility and adaptability are limited
Solution Approach 1:
The patent introduces a configuration file as an intermediary layer between the user and the diagnostic system. This configuration file allows users to define custom PIDs, scaling factors, and offset values without modifying the core diagnostic software, thereby providing flexibility while maintaining system simplicity.
Solution Approach 2:
The system dynamically loads and applies conversion parameters from configuration files at runtime, allowing users to adapt the diagnostic behavior without reprogramming. This dynamic approach enables flexibility while keeping the base system simple and reliable.
2Adaptability or versatility
If reprogramming is required to create new data values, then customization capability is improved, but ease of operation and accessibility deteriorate
Solution Approach 1:
The system enables users to define their own data processing parameters through configuration files without requiring programming expertise. Users can specify custom PIDs, scaling factors, and offset values in a user-friendly format, allowing self-service customization while maintaining ease of operation.
3Measurement precision
If linear scaling functions are used for data conversion, then processing speed is maintained, but measurement precision and accuracy are limited
Solution Approach 1:
The patent allows users to define custom scaling factors and offset values through configuration files, enabling precise linear transformations of diagnostic data. This approach maintains processing efficiency while improving measurement precision by allowing tailored conversion parameters for different vehicle systems.
