Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional diagnostic methods are used for vehicle component repair, then comprehensive error information can be obtained through extensive testing, but the repair process becomes time-consuming and complex
Solution Approach 1:
The patent applies preliminary action by storing error information in advance on RFID tags attached to vehicle components during manufacturing or previous service operations. This pre-stored information includes diagnostic data, error codes, and component history that would otherwise require extensive testing to gather. When repair is needed, this information is immediately available for retrieval, eliminating the need for time-consuming diagnostic procedures while ensuring complete error information is obtained.
2Reliability
If extensive diagnostic testing is performed to gather complete error information, then accurate repair decisions can be made, but the complexity of the repair process increases
Solution Approach 1:
The patent extracts error information and diagnostic data from the complex diagnostic testing process and stores it directly on RFID tags attached to components. This separation removes the need for complex diagnostic equipment and procedures, as the essential information is already captured and stored on the component itself. The RFID tag acts as a self-contained information repository that simplifies the repair decision-making process while maintaining high reliability.
3Productivity
If error information is stored on RFID devices for quick retrieval, then the repair process is simplified and accelerated, but energy is required for wireless communication operations
Solution Approach 1:
The patent employs passive RFID tags that require minimal energy for communication. These passive tags harvest energy from the electromagnetic field generated by the reader during brief communication windows, eliminating the need for batteries or power sources. The energy consumption is negligible and limited to short bursts during data retrieval, making the productivity gain worthwhile while keeping energy usage minimal. The tags are designed for single-use or long-term passive operation without active power management.
