Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication connection is used for FLASH programming, then data transmission reliability is improved, but operational flexibility and range are worsened due to cable length limitations
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The scan tool uses a wireless interface to communicate with the personal computer, eliminating the physical cable that limited operational range and flexibility. This substitution maintains data transmission reliability while dramatically improving ease of operation and technician mobility.
2Length of moving object
If cable length is extended to increase operating range, then distance capability is improved, but cable durability and reliability are worsened due to increased susceptibility to damage
Solution Approach 1:
The patent eliminates the mechanical cable system entirely by implementing wireless communication between the scan tool and personal computer. This removes the physical constraints of cable length and the associated reliability issues of cable damage from high-traffic areas, while providing unlimited operational range.
3Stability of the object's composition
If wired connection is used for software updates, then connection stability is improved, but maintenance requirements are worsened due to cable deterioration
Solution Approach 1:
The patent replaces the wired connection system with a wireless communication system, eliminating physical cables that deteriorate over time. The wireless connection maintains stable data transmission for software updates while completely eliminating maintenance requirements associated with cable insulation deterioration and physical wear.
4Ease of operation
If wireless communication is implemented, then operational range and flexibility are improved, but communication protocol compatibility is worsened
Solution Approach 1:
The patent employs communication protocol translators as intermediary devices that facilitate wireless communication between the scan tool and personal computer. These translators handle protocol conversion and compatibility issues, allowing the wireless system to support multiple vehicle communication protocols (CAN, LIN, ISO 9141, J1850) without compromising operational flexibility.
Data Source
AI summary
A diagnostic tool and method are provided wherein the diagnostic tool includes a wireless communication circuit to retrieve diagnostic software from a remote computing device. When operated, the scan tool can determine if the loaded diagnostic software is appropriate for the vehicle under test. If not, the diagnostic tool can retrieve the appropriate diagnostic software from the remote computing device. The retrieved or second diagnostic software is then operated to reprogram the diagnostic tool to remove the previously loaded software and allow a user to service a vehicle.
