Ladder Integrated Lighting Device for Smoke Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firefighters face difficulty locating ladders in smoke-filled buildings during fire responses due to limited visibility, and they often need to carry additional tools to break windows, which slows down their entry and exit processes.
Innovation Solution
A lighting device integrated with a ladder that emits different types of lights in various directions, including visible and infrared lights, to illuminate the surrounding area and a cutting blade for breaking windows, allowing firefighters to quickly locate the ladder and enter/exist the building without extra tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If firefighters use conventional ladders without integrated lights, then the ladder structure remains simple, but the visibility of the ladder in smoke-filled buildings is poor
Solution Approach 1:
The patent combines the lighting device with the ladder structure by integrating a coupling mechanism that attaches the light source to the ladder rails. The lighting device is merged with the ladder such that the projections on the lighting device engage with slots or chambers in the ladder rails, creating a unified system where the ladder serves both as access equipment and as a mounting structure for illumination.
Solution Approach 2:
The ladder is enhanced with multiple functions: it serves as both the traditional access tool and as a mounting structure for the lighting device. The coupling mechanism allows the lighting device to be attached to and moved with the ladder, enabling the ladder to provide both structural support and illumination functionality simultaneously.
2Adaptability or versatility
If firefighters carry additional tools to break windows, then the window breaking capability is improved, but the time required for entry and exit is increased
Solution Approach 1:
The cutting blade is integrated into the lighting device by positioning it at the front end of the device. This merging of the cutting function with the lighting function allows the firefighter to break windows and provide illumination using a single integrated tool, eliminating the need to carry separate window-breaking tools.
Solution Approach 2:
The cutting blade is pre-positioned on the lighting device, ready for immediate use. The blade can be used to break windows before the ladder is fully positioned or during the entry process, preparing the access point in advance and reducing the overall time required for entry and exit operations.
3Area of stationary object
If the lighting device emits lights in multiple directions, then the coverage area is improved, but the device complexity is increased
Solution Approach 1:
Different light sources are positioned at different locations within the lighting device to provide targeted illumination in specific directions. The first light source illuminates the area inside the building through the window, while the second light source illuminates the area outside the building, creating localized illumination zones that together provide comprehensive coverage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances visibility of the ladder and surrounding area through targeted lighting, enabling faster access and egress from buildings, even in heavy smoke conditions, and reduces the time needed to break windows with an integrated cutting blade.
Implementation Method 1
The lighting device may include a first light source positioned at a first end of the lighting device and a second light source positioned at a second end of the lighting device

AI summary
Embodiments disclosed herein describe systems and methods for a lighting device that is configured to couple with the end of a ladder. The lighting device may be configured to illuminate a room within a building with different types of light being projected in different, predetermined directions. Therefore, a firefighter within the building may be able to determine the location of the ladder even if heavy smoke is positioned within the building. Accordingly, the firefighter may be able to enter the building quicker because the firefighter may not have to bring an extra light, while also allowing the firefighter to exit the building quicker.
