Aircraft Display Module Dynamic Content Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display modules for aircraft are inflexible, limiting the number of pictograms and languages that can be displayed, requiring significant development and long delivery times, and are not optimized for new communication systems that require more complex information.
Innovation Solution
A display module with a control unit, storage device, and interfaces that allow for the storage and display of various image elements, icons, video sequences, and texts, enabling flexible use of available space and support for multiple languages, with operation modes including databus, DC data, and standalone modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed pictograms are integrated in the light disc, then the display module structure is simple and reliable, but the flexibility and adaptability are limited
Solution Approach 1:
The patent applies the dynamics principle by replacing fixed pictograms with a dynamic display system that can change content based on stored data. The display module can now show different pictograms, texts, and images depending on the stored data content, making the system adaptable without requiring physical reconfiguration.
Solution Approach 2:
The patent uses the copying principle by storing pictogram data and other display content in a storage device rather than physically integrating them. This allows the same physical display hardware to represent multiple different pictograms and content types through data copying and retrieval, eliminating the need for multiple physical light discs.
2Adaptability or versatility
If more pictograms and languages are to be displayed, then the information content increases, but the development time and cost increase significantly
Solution Approach 1:
The patent applies the preliminary action principle by pre-storing pictogram data, text data, and other display content in the storage device during manufacturing or setup. This allows the display module to be quickly configured for different languages and pictograms without requiring time-consuming development and qualification processes for each new configuration.
Solution Approach 2:
The patent uses parameter changes by allowing the display content to be changed through data parameters stored in memory rather than physical modifications. Different languages and pictograms are selected by changing the data parameters retrieved from storage, enabling rapid reconfiguration without redevelopment.
3Adaptability or versatility
If text explanations are firmly entered into the light disc, then the display is simple, but the ability to provide multi-language explanations is limited
Solution Approach 1:
The patent applies the copying principle by storing text explanations and pictogram data separately in the storage device, allowing the same physical display to present different languages and content combinations. This separates the physical display structure from the content, enabling multi-language capability without increasing physical complexity.
4Adaptability or versatility
If only two pictograms are incorporated in the light disc, then the device remains simple, but the capability to display complex information from new communication systems is limited
Solution Approach 1:
The patent applies the dynamics principle by enabling the display to dynamically adapt its content capacity based on the communication system requirements. The storage device can hold multiple pictograms and complex information, allowing the display to expand its capacity when needed for new communication systems without physical redesign.
