Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting systems for rescuing trapped victims are cumbersome and time-consuming, posing risks to rescue workers due to the need for multiple component assembly and unstable conditions during deployment.
Innovation Solution
A compact, integrated lifting system with an inflatable body connected to a fluid conduit that is wound around a rotation axis, allowing for remote operation and rapid deployment via a reel mechanism, incorporating a fluid reservoir and electronic control, and featuring a rolling undercarriage for safe positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the lifting system uses multiple separate components (air hoses, compressed air cylinder, pressure controller, control unit), then the system functionality is complete, but the assembly time increases and rescue worker safety decreases
Solution Approach 1:
The patent combines multiple separate components (compressed air cylinder, pressure controller, control unit, air hoses) into an integrated lifting system where the control unit and pressure controller are mounted on the platform, and the compressed air cylinder is integrated with the reel mechanism. This merging reduces assembly time by eliminating the need to couple multiple separate components during rescue operations.
2Ease of operation
If the rescue worker approaches the object to place the lifting system, then the placement can be performed, but the rescue worker is exposed to danger from unstable objects
Solution Approach 1:
The lifting system is designed to be self-positioning through the reel mechanism that automatically winds and unwinds the air hose as the platform is moved into position. The integrated design allows the system to be deployed with minimal manual intervention near the unstable object, as the reel mechanism handles the hose management automatically.
3Productivity
If the fluid conduit is coupled to an external fluid system, then the inflatable body can be inflated, but the coupling process increases assembly time and reduces response speed
Solution Approach 1:
The compressed air cylinder and pressure controller are pre-integrated with the platform and reel mechanism before deployment. The air hose is pre-attached to the inflatable body, and all components are positioned and connected in advance, eliminating the need for time-consuming coupling operations during the rescue response.
4Ease of manufacture
If the lifting system components are distributed separately, then each component can be optimized independently, but the overall system size and storage requirements increase
Solution Approach 1:
The air hose is wound around the reel mechanism, which is mounted on the platform. The pressure controller and control unit are mounted on the platform structure. The compressed air cylinder is integrated with the reel assembly. This nested arrangement allows all components to be stored in a compact configuration on the platform, reducing the overall system volume and improving portability.

AI summary
A lifting system comprises a platform (10) with at least one inflatable body (21, 22) which is connected to a fluid conduit (23, 24) for the purpose of receiving an inflating fluid, particularly a gas under increased pressure such as compressed air. In a first aspect the at least one inflatable body (21, 22) is connected for rotation about a rotation axis (H) relative to the platform (10). The inflatable body (21, 22) bounds here a winding space (40) in which the fluid conduit, when not in use, is received in a state in which it is wound around the rotation axis. In a second aspect the lifting system comprises on or at the platform (10) a fluid system (51, 52) which is remotely controllable.
