Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional adhesive labels on aircraft distribution assemblies are difficult to read, require multiple labels for maintenance, and fail to identify wireless connections, making maintenance and troubleshooting inefficient, especially when the system is powered off.
Innovation Solution
An electronic label system with a communication link to a line replaceable unit, providing real-time information via a chip or RFID tag, which can be accessed even when the unit is powered off, including critical failure data, health data, and connection information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional adhesive labels are used on distribution assembly, then labeling is simple and inexpensive, but the labels are difficult to read, cannot be updated, and fail to identify wireless connections
Solution Approach 1:
The patent replaces traditional mechanical adhesive labels with an electronic label system that uses electronic displays and communication protocols. The electronic label includes a display element and can communicate with the line replaceable unit through a communication link, substituting the static mechanical labeling system with a dynamic electronic information system that provides real-time data access.
Solution Approach 2:
The patent introduces an electronic label as an intermediary between the line replaceable unit and the maintenance personnel. This electronic label acts as a mediator that can display information, store data, and communicate system status, bridging the gap between the internal unit data and external human operators more effectively than traditional labels.
2Loss of information
If multiple adhesive labels are used for maintenance instances, then more information can be provided, but the device complexity increases and maintenance becomes less efficient
Solution Approach 1:
The patent implements a universal electronic label system that can perform multiple functions: displaying identification information, showing system status, providing maintenance instructions, and storing diagnostic data. This single multi-functional electronic label replaces the need for multiple specialized adhesive labels, reducing overall system complexity while maintaining comprehensive information availability.
Solution Approach 2:
The electronic label system is dynamic and can update its displayed information in real-time based on the system state, whereas traditional adhesive labels are static. The electronic label can change its content to reflect different maintenance instances, system configurations, and diagnostic information without requiring physical replacement or addition of labels.
3Loss of information
If aircraft is powered on to access system information, then complete diagnostic data is available, but maintenance time increases and system availability decreases
Solution Approach 1:
The electronic label system performs preliminary action by continuously monitoring and storing diagnostic information from the line replaceable unit while the system is operating. This pre-capture of diagnostic data allows maintenance personnel to access complete system information without needing to power on the aircraft, as the data has already been collected and is ready for immediate review during maintenance activities.
