Inflatable Corpse Mattress for Rapid Lifting in Tight Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for lifting and transporting corpses from inaccessible locations are cumbersome, potentially injurious to personnel, and difficult when the corpse is heavy, as they often require manual repositioning and lack adequate support.
Innovation Solution
An inflatable mattress system with two elongated chambers and a rectangular chamber, equipped with straps for securing the corpse and an inflation device for rapid inflation to a selected height, allowing easy transfer from the location of death to a gurney or mortuary cot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional methods (cot or board) are used to lift and move the corpse, then the corpse can be supported and moved, but personnel may be injured and it is difficult to maneuver through tight spaces
Solution Approach 1:
The patent uses an inflatable mattress with air chambers to lift and support the corpse. By inflating the mattress with air, the corpse is elevated to a comfortable working height without requiring personnel to physically lift or support the heavy body, thereby eliminating injury risk while maintaining ease of movement through tight spaces.
Solution Approach 2:
The mattress can be inflated to different heights depending on the situation. This parameter change allows the corpse to be lifted to an optimal height for maneuvering through doorways or positioning on a gurney, making the operation easier and safer without fixed height constraints.
2Adaptability or versatility
If the corpse is lifted and positioned fully upright to move through doorways or corners, then the corpse can be maneuvered through various locations, but it becomes physically taxing and dangerous for heavy corpses
Solution Approach 1:
The inflatable mattress provides buoyant support that allows the corpse to be elevated and repositioned without personnel bearing the full weight. The air-filled chambers create a supportive surface that can be easily maneuvered while reducing physical strain on handlers.
Solution Approach 2:
The mattress can be dynamically adjusted by inflating or deflating chambers as needed during the moving process. This allows the system to adapt to different maneuvering requirements while maintaining ease of operation, as the mattress can be quickly adjusted to facilitate movement through various locations.
3Ease of operation
If additional support devices are provided for lifting and moving the corpse, then lifting and moving becomes easier, but the location and distance may not allow additional support to be easily provided
Solution Approach 1:
The inflatable mattress serves multiple functions: it provides lifting support, creates a movable platform for transport, and can be adjusted to different heights. This multi-functionality eliminates the need for multiple separate support devices, reducing overall system complexity while maintaining ease of operation.
Solution Approach 2:
The mattress can be inflated to different heights based on the specific situation, providing adaptable support without requiring complex mechanical adjustment mechanisms. This parameter change capability allows the same simple device to accommodate various lifting and moving scenarios.
4Productivity
If the inflatable mattress is inflated rapidly to raise the corpse, then the lifting time is reduced, but the inflation system must be compact and portable
Solution Approach 1:
The system uses a portable air compressor or pump to rapidly inflate the mattress chambers. This pneumatic approach enables quick lifting (within 2 minutes as specified) while keeping the inflation device compact and portable, suitable for emergency response scenarios.
Solution Approach 2:
The inflation system is pre-positioned at the scene and can be activated immediately upon arrival. The rapid inflation capability allows the mattress to be deployed and the corpse lifted within 2 minutes, minimizing response time without requiring complex or bulky equipment.
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 inflatable mattress provides stable support for the corpse, reducing manual labor and injury risk, enabling safe and efficient transport of corpses, even those exceeding 250 pounds, by inflating to a suitable height in under 2 minutes, facilitating movement through tight spaces and reducing physical strain on personnel.
Implementation Method 1
The inflatable mattress may be at least partially inflated with compressed gas provided into the inflatable mattress to raise the human corpse located on the surface of the mattress a selected height

AI summary
An inflatable mattress is placed in a deflated state at a location a human corpse departed from life. The inflatable mattress may include two elongated chambers and one rectangular mattress chamber that supports the human corpse. The inflatable mattress may include one or more devices for coupling the human corpse to a top surface of the inflatable mattress. An inflation device coupled to the inflatable mattress is used to inflate the inflatable mattress to a selected height in less than about 2 minutes with the human corpse coupled to the inflatable mattress. The inflatable mattress is movable, with the human corpse coupled to the inflatable mattress, from the location the human corpse departed from life to a secondary location.
