Aircraft Evacuation Slide Visual Guidance System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The efficiency of aircraft evacuation slides is hindered by passenger hesitation and incorrect entry methods, leading to increased egress time and potential injuries due to pushing and non-optimal positioning, especially in multi-lane scenarios.
Innovation Solution
The implementation of visually distinct jump targets and lane markers on the slide, illuminated by fuselage and ramp lights, to guide passengers on optimal entry points and lane usage, along with a central divider and end indicators to enhance visibility and clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If visual markings and lighting are added to the slide, then passenger guidance and entry efficiency are improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-positioning visual markings (lane markers, jump targets, end indicators) and lighting systems on the slide before evacuation occurs. These elements are prepared in advance to guide passengers through the correct entry procedure, reducing hesitation and improving evacuation efficiency without requiring complex real-time control systems.
Solution Approach 2:
The patent utilizes color changes and visual contrast by employing brightly colored lane markers, jump targets, and end indicators that stand out against the slide background. The lighting system enhances visibility by illuminating these visual cues, making them easily distinguishable to passengers in various lighting conditions, thereby improving guidance without adding mechanical complexity.
2Productivity
If multiple slide lanes are provided, then evacuation capacity is improved, but passenger confusion and incorrect entry increase
Solution Approach 1:
The patent applies segmentation by dividing the slide into distinct lanes with clear visual separators (lane markers). Each lane is independently marked with jump targets and end indicators, allowing passengers to quickly identify and enter the correct lane without confusion. This segmentation maintains high evacuation capacity while improving entry clarity through visual differentiation.
Solution Approach 2:
The patent implements local quality by providing specific visual markings and lighting at different locations along each lane (entry markers at the top, jump targets in the middle, end indicators at the bottom). Each section has tailored visual characteristics that guide passengers through their specific path, making multi-lane navigation intuitive and reducing confusion while maintaining high evacuation capacity.

AI summary
An evacuation slide to provide an egress path from an exit of an aircraft. The evacuation slide includes one or more slide lanes. One or more jump targets and indicators are positioned along each of the slide lanes to visually inform persons how to enter a ramp of the slide. Lights illuminate one or more sections of the slide to further provide visual guidance on how to enter the ramp.
