Stretcher Receiving Device With Tilting Joint And Guide Carriage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The loading of stretchers into transport vehicles, especially in emergency and military contexts, is cumbersome, strenuous, and dangerous due to the need for multiple handlers and the potential for stretchers to be at elevated heights, making it difficult and time-consuming.
Innovation Solution
A stretcher receiving device with a tilting joint and guide carriage system that allows for easy loading and unloading by two people, featuring a frame with longitudinal and transverse members, a storage platform, and locking elements to secure the stretcher at hip height, enabling efficient and safe handling even when the loading area is above the helper's height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If stretchers are loaded by traditional manual methods, then multiple handlers are required, but this increases the time-consuming and strenuous nature of the loading process
Solution Approach 1:
The patent introduces a receiving device as an intermediary mechanism between the stretcher and the transport vehicle. This device includes a tilting platform and guide carriage system that facilitates the transfer of the stretcher from horizontal carrying position to vertical storage position, reducing the manual effort and time required for loading while maintaining safety.
Solution Approach 2:
The receiving device employs dynamic elements including a tilting platform that can rotate between horizontal and vertical positions, and a guide carriage that moves along rails. These dynamic components enable the device to adapt to different loading scenarios and reduce the physical strain on handlers by mechanically assisting the stretcher transfer process.
2Ease of operation
If stretchers are loaded at elevated heights, then the loading area can be accessed, but this makes the loading process dangerous and strenuous for rescuers
Solution Approach 1:
The tilting platform rotates from a horizontal position (for easy stretcher placement) to a vertical position (for secure storage), allowing handlers to load stretchers at elevated heights without exposing themselves to danger. The mechanical tilting action brings the loading surface to the handler's level while maintaining safety at the elevated position.
Solution Approach 2:
The guide carriage system acts as an intermediary mechanism that bridges the gap between the handler's level and the elevated loading area. The carriage moves along rails to position the stretcher receptacle at the appropriate height, reducing the physical strain and safety risks associated with manual lifting at elevated positions.
3Quantity of substance
If multiple stretchers are arranged one on top of the other, then more patients can be accommodated, but this makes loading even more difficult
Solution Approach 1:
The receiving device can accommodate multiple stretchers vertically by tilting the platform to vertical positions for each stretcher. The guide carriage system allows sequential loading of multiple stretchers in the same vertical space, increasing the number of patients that can be accommodated without making loading more difficult.
Solution Approach 2:
The patent transitions from horizontal stacking to vertical stacking by utilizing the vertical dimension through the tilting platform and guide carriage mechanism. This dimensional change allows multiple stretchers to be arranged one on top of the other while maintaining ease of loading through the mechanical assistance provided by the receiving device.
4Ease of operation
If the stretcher receptacle is positioned horizontally within the frame, then it is compact, but this prevents easy loading when the loading area is at or above person height
Solution Approach 1:
The stretcher receptacle is mounted on a tilting platform that can rotate between horizontal and vertical positions. This dynamic positioning allows the receptacle to be horizontal for compact storage within the frame, yet easily tiltable to vertical positions for loading stretchers at or above person height, maintaining both compactness and ease of operation.
Solution Approach 2:
The receiving device is segmented into functional components: the tilting platform for position change, the guide carriage for movement along rails, and the stretcher receptacle for holding the stretcher. This segmentation allows each component to perform its specific function independently, managing structural complexity while enabling easy loading at elevated positions.
