Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual programming is used to configure engine controllers during engine interchange, then the process can be performed with simple equipment, but human error occurs during programming
Solution Approach 1:
The patent replaces manual mechanical programming operations with automated optical scanning and wireless data transmission. A mobile device scans a computer-readable label on the engine to automatically obtain trim values, eliminating the need for manual programming and reducing human error while maintaining system simplicity through wireless communication.
Solution Approach 2:
The engine controller performs self-configuration by automatically receiving trim values through wireless communication from a mobile device that scans the engine's label. This self-service approach eliminates the need for technician intervention in the actual programming process, improving reliability while keeping the system straightforward to implement.
2Productivity
If manual programming is used by technicians, then equipment requirements are minimal, but the process is time-consuming and prone to errors
Solution Approach 1:
The patent replaces time-consuming manual programming with automated optical scanning and wireless data transmission. The mobile device rapidly scans the computer-readable label and transmits trim values wirelessly to the engine controller, significantly reducing configuration time while maintaining minimal equipment requirements.
Solution Approach 2:
The trim values are pre-encoded on the computer-readable label attached to the engine before interchange. This preliminary preparation allows for rapid automatic retrieval during configuration, eliminating the need for manual data entry and accelerating the programming process without requiring additional equipment.
3Reliability
If automated wireless transmission is implemented, then programming accuracy improves, but device complexity increases
Solution Approach 1:
The patent uses a mobile device, which is a universal multi-functional tool already common in maintenance environments. The mobile device performs optical scanning, data extraction, and wireless communication functions that would otherwise require specialized equipment, thereby improving accuracy without significantly increasing system complexity.
Solution Approach 2:
The computer-readable label serves as an intermediary carrier that stores trim values in machine-readable format. This intermediary enables automatic data transfer from the engine to the controller through wireless communication, improving programming accuracy while using a simple, non-intrusive component that does not add significant complexity to the system.
Data Source
AI summary
Systems and methods for configuring operation of an engine are described herein. A computer-readable label associate with the engine is read by a mobile device to obtain label information having at least one trim value for the engine encoded therein. The at least one trim value is extracted from the label information on the mobile device. The at least one trim value is wirelessly transmitted from the mobile device to a data transmission unit of the engine. The data transmission unit is configured for instructing an electronic engine controller to trim the engine with the at least one trim value during operation of the engine.
