Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cable loom connections are used for power supply and data transmission, then reliable electrical connection is achieved, but device complexity and assembly time increase significantly
Solution Approach 1:
The patent combines power supply and data transmission functions into a single integrated flexible layer with printed circuits. The flexible polymer film layer integrates power conductors, data conductors, and control circuits into one unified structure, eliminating the need for separate cable looms and multiple connection points. This merging reduces the number of components and simplifies installation while maintaining reliable electrical connections.
Solution Approach 2:
The patent replaces mechanical cable loom connections with a flexible printed circuit board system. Instead of using traditional mechanical wiring harnesses that require manual routing and connection, the flexible layer with printed conductors provides a more streamlined electrical connection system that is easier to install and maintain.
2Adaptability or versatility
If multiple separate components are installed for information panels, then functional requirements are met, but assembly time increases to several hours
Solution Approach 1:
The patent merges multiple functional components into a single integrated display unit. The flexible layer integrates power supply, data transmission, and control functions into one assembly, allowing the entire information panel to be installed as a single unit rather than assembling multiple separate components, thereby reducing assembly time from several hours to minutes.
Solution Approach 2:
The patent segments the information panel into modular components that can be independently configured but assembled into a unified system. The flexible layer can be customized with different circuit configurations for power, data, and control functions, allowing functional adaptability while maintaining quick assembly through standardized integration.
3Productivity
If integrated circuits on flexible layer are used, then assembly time and complexity are reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent replaces manual circuit assembly with automated printed circuit technology. The flexible polymer film layer uses printed conductors and integrated circuits that are manufactured with precise positioning through printing and lamination processes, eliminating the need for manual wiring and reducing assembly time while maintaining high precision through automated manufacturing techniques.
4Reliability
If conventional power supply with cable looms is used, then power delivery is reliable, but the system requires manual installation and maintenance
Solution Approach 1:
The patent combines power supply functionality directly into the flexible layer that also handles data transmission and control. This integration eliminates the need for separate cable loom installation and simplifies maintenance, as the power supply is now part of the single flexible assembly that can be easily replaced or serviced as one unit while maintaining reliable power delivery.

AI summary
An indicator apparatus for guiding interior aircraft occupants has a mounting device fastenable to a wall portion of the interior and having an indicator conveying an item of visual information to occupants. An indicator can be or is operated electrically, and the indicator can be or is connected to a power supply for operation. To create an indicator apparatus which helps improve orientation of cabin passengers, can be produced, installed and serviced easily, and which can be operated in a fail-safe manner in an emergency situation of the aircraft, the indicator has an at least one-piece layer, on which circuitry necessary for operation is provided in an integrated fashion, and the power supply is formed by a composite structure battery built up layer by layer and can be or is connected to the layer. A method for producing an indicator apparatus of this kind is disclosed.
