Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate lighting systems with individual bulbs are used, then lighting functionality is provided, but maintenance complexity and weight increase

Engineering Contradiction:
Improvemaintenance efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines separate lighting, signage, and display systems into a single integrated LED panel system. Multiple functions that previously required separate bulbs, wiring systems, and control mechanisms are merged into one unified structure using high-density LED arrays on flexible circuit boards, eliminating the need for individual bulb replacements and reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The LED panel system performs multiple functions simultaneously - providing ambient lighting, displaying safety signage, showing directional indicators, and presenting video content - all through a single multi-functional device. This universal approach replaces numerous single-function components with one adaptable system that can switch between different operational modes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If conventional lighting systems are used, then basic lighting is provided, but interactivity and flexibility are limited

Engineering Contradiction:
ImproveinteractivityVSAvoidoperational flexibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system transitions from static, fixed-function lighting to a dynamic, programmable display system. The LED panels can change colors, patterns, and content in real-time based on control signals, enabling interactive capabilities such as responsive lighting scenes, animated safety messages, and synchronized entertainment displays that adapt to different operational contexts.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system allows dynamic adjustment of multiple parameters including brightness levels, color temperature, display content, and operational timing. These parameters can be modified through software control to create different lighting scenes, adjust display intensity based on ambient conditions, and customize the system behavior for various flight phases or passenger needs.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple separate systems are installed, then comprehensive functionality is achieved, but weight increases

Engineering Contradiction:
Improvedisplay functionalityVSAvoidsystem weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent consolidates multiple separate systems (lighting fixtures, signage displays, video screens) into a single integrated LED panel structure. This merging eliminates redundant components such as separate power supplies, control systems, and mounting structures, thereby reducing the total weight while maintaining all required functionalities within a unified lightweight platform.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An integrated aircraft lighting and display panel includes high-density arrays of micro-scale light-emitting diodes (LED) set into a flexible printed circuit board (PCB). The PCB and LED arrays may be set into structural layers corresponding to overhead panels, side panels, bin panels, divider panels, doorway panels, or other interior structural panels of the aircraft. The LED arrays may be activated by a controller to provide cabin lighting, indicate aircraft signage, display high-resolution image or video graphics, or any simultaneous combination of all three. The panel may have a translucent or transparent decorative outer skin which may mimic the outward appearance of wood, stone, bamboo, or other decorative materials while the integrated lighting and display panels are inactive. Highly reflective core materials, such as an aluminum core in a honeycomb pattern, may guide the luminous output of the LED arrays through the outer skin.
