A portable data transmission unit integrated with an aircraft engine's on-board performance monitoring system, enabling real-time voice and data communication via a transceiver, with a user interface for displaying and receiving maintenance data, and allowing direct communication with remote terminals for assistance during maintenance operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If maintenance personnel use cell phones and hard copy manuals during servicing, then they can access information and communicate, but they must juggle multiple devices and documents which is time-consuming and hazardous
Solution Approach 1:
The patent combines the cell phone, hard copy manual, and tools into a single integrated maintenance terminal. The terminal displays maintenance information from manuals on its screen, provides communication capabilities through an integrated phone system, and stores all necessary information in one location, eliminating the need to juggle multiple separate devices and documents during maintenance operations.
Solution Approach 2:
The maintenance terminal is designed as a multi-functional device that performs multiple functions: it displays maintenance information, provides communication capabilities, stores maintenance data, and integrates with the aircraft's monitoring systems. This universal device replaces the need for multiple specialized tools and documents, allowing maintenance personnel to access all necessary information and communicate through a single unit.
2Loss of information
If maintenance personnel use cell phones and hard copy manuals, then they can communicate and consult information, but clear communication becomes difficult when juggling multiple devices
Solution Approach 1:
The maintenance terminal merges communication functions directly into the maintenance interface. The terminal includes an integrated phone system and display that shows maintenance information while allowing communication with support personnel. This integration ensures that maintenance personnel can communicate clearly without having to switch between multiple devices, as all communication and information access occur through the single terminal unit.
3Reliability
If maintenance personnel physically move away from the maintenance area to use communication devices, then they can communicate more effectively, but safety is compromised and time is lost
Solution Approach 1:
The maintenance terminal combines all necessary communication and information access functions in a single unit that can be used directly at the maintenance location. The terminal includes an integrated display, phone system, and data storage, allowing maintenance personnel to communicate and consult information without leaving the maintenance area, thereby maintaining safety and eliminating time loss from moving between locations.
