Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If vehicle scanners use sophisticated electronic equipment and extensive diagnostic processes to diagnose complex modern vehicles, then diagnostic accuracy is improved, but repair time and learning curves increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring and storing multiple diagnostic test suites in the scanner's memory, each tailored for specific vehicle systems or fault types. When a technician selects a test suite, the scanner automatically executes the pre-programmed diagnostic sequence, eliminating the need for technicians to manually navigate through extensive diagnostic procedures during repair, thus reducing repair time while maintaining diagnostic accuracy
Solution Approach 2:
The patent segments the comprehensive diagnostic process into multiple independent test suites, each focusing on a specific vehicle system or fault category. This segmentation allows technicians to quickly select and execute only the relevant diagnostic tests needed for the particular problem, rather than running through all possible diagnostic procedures, thereby reducing overall diagnostic time while preserving accuracy for the specific issue at hand
2Reliability
If vehicle scanners provide comprehensive diagnostic capabilities for complex vehicles, then diagnostic thoroughness is improved, but device complexity increases
Solution Approach 1:
The patent segments the comprehensive diagnostic functionality into multiple separate, standardized test suites that can be independently stored and executed. Each test suite is self-contained and focuses on a specific diagnostic function, allowing the scanner to provide thorough diagnostic capabilities through a modular architecture rather than a monolithic complex system, making the device more manageable and easier to operate
Solution Approach 2:
The patent implements universality by designing a standardized test suite format and interface that can be applied across different vehicle types and diagnostic scenarios. The scanner can execute the same basic test suite structure for various vehicle systems, reducing the need for entirely separate diagnostic tools for each function, thereby providing comprehensive diagnostic thoroughness without proportionally increasing device complexity
3Adaptability or versatility
If repair technicians use manual diagnostic procedures with extensive equipment, then diagnostic coverage is improved, but ease of operation decreases
Solution Approach 1:
The patent applies self-service by enabling the scanner to automatically execute diagnostic test suites with minimal technician intervention. Once a technician selects the appropriate test suite for the vehicle or fault type, the scanner autonomously performs the diagnostic sequence, interprets results, and presents findings, reducing the burden on technicians to manually operate complex diagnostic equipment while maintaining comprehensive diagnostic coverage
Solution Approach 2:
The patent uses preliminary action by pre-configuring standardized test suites with all necessary diagnostic procedures, parameters, and interpretation logic already programmed into the scanner. This preparation in advance allows technicians to simply select and execute tests without needing to understand or manually configure complex diagnostic parameters, greatly simplifying operation while ensuring comprehensive diagnostic coverage through the pre-validated test sequences
Data Source
AI summary
Disclosed are systems and methods for a vehicle scanner to automatically execute applications from a removable storage card. The method includes detecting a presence of one or more executable diagnostic requests in removable data storage, and responsive to the detection, transmitting one or more corresponding requests for vehicle diagnostic data to the vehicle via a vehicle interface. Responsive to the transmission, the vehicle scanner receives and processes diagnostic data from the vehicle. The vehicle scanner may store the data back to the removable storage card, or may transmit the data via a wired or wireless interface to a display device. As part of the detection process, the vehicle scanner may first authenticate the removable storage card before executing vehicle diagnostic instructions from the card.
