Rescue Sled Assembly With Integrated Lighting And Handles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rescue devices lack the necessary features to effectively and safely rescue individuals who have fallen through ice on a body of water, as they do not incorporate lights, handles, and tethers to facilitate the rescue process.
Innovation Solution
A rescue sled assembly comprising buoyant floats, a connecting frame, tethers, handles, light emitters, and a power source, designed to allow for safe and efficient rescue by providing a grip for the person to hold onto and illumination for visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing rescue devices are used on ice-covered water, then the rescue operation can be performed, but the safety and effectiveness of the rescue is insufficient due to lack of lights, handles, and tethers
Solution Approach 1:
The patent combines multiple rescue functions into a single integrated sled device. The sled merges the flotation device, handling mechanism (handles and tethers), and illumination system (lights with power source) into one unified rescue apparatus, eliminating the need for separate equipment and improving overall rescue safety
Solution Approach 2:
The rescue sled serves multiple functions simultaneously: it provides flotation and stability on water, offers handles and tethers for secure handling and pulling, and includes lights for visibility in low-light conditions. This multi-functionality addresses various rescue needs within a single device structure
2Ease of operation
If existing rescue devices without handles are used, then the device structure remains simple, but the ease of operation during rescue is reduced
Solution Approach 1:
The sled incorporates multiple separate handles positioned at different locations on the frame structure. This segmentation allows rescuers to grab onto specific handles based on their position and needs, improving ease of operation while maintaining a relatively simple overall device structure
3Illumination intensity
If existing rescue devices without illumination are used, then the device complexity remains low, but the visibility and effectiveness during rescue operations is insufficient
Solution Approach 1:
The sled is equipped with lights and a power source that are pre-installed and ready for use before the rescue operation begins. This preliminary preparation ensures immediate visibility when needed, without requiring complex electrical setup during the emergency rescue situation
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
The rescue sled assembly enables safe and efficient rescue operations by providing a stable grip and illumination, allowing individuals to be pulled out from openings in ice-covered bodies of water effectively.

AI summary
A rescue sled assembly for use on ice or water includes a pair of floats being buoyant in water and being capable of sliding upon the ice-covered body of water. A frame is coupled to the pair of floats, wherein the frame connects the floats to each other. A plurality of tethers is engaged with the frame and facilitates pulling of the frame and floats in a selected direction and orientation. A plurality of handles is coupled to the frame and provides a grip for a person to grab onto the frame when being pulled out from an opening of an ice-covered body of water. A plurality of light emitters is coupled to the frame and emits light when turned on.
