Rollable Base Plate With Integrated Retaining Tabs For Injured Person Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing towable and portable transport means are limited in their ability to facilitate ground and helicopter transport, particularly for injured persons, due to lack of flexibility and additional equipment requirements, and do not allow for efficient sliding over varying surfaces.
Innovation Solution
A base plate that can be rolled up during transport with integrated retaining tabs and stiffening elements, allowing for easy attachment of transport aids without compromising sliding properties, and featuring retractable stiffening elements and carrying straps for versatile use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stiffening elements are added to support the upper body of an injured person, then transport stability and support capability are improved, but device complexity and setup time increase
Solution Approach 1:
The retaining tabs are integrated directly into the base plate structure, combining the support function with the transport device itself. This eliminates the need for separate stiffening elements while maintaining the capability to support an injured person's upper body during transport.
Solution Approach 2:
The base plate structure serves its own stiffening function through the integrated retaining tabs, eliminating the need for additional external equipment. The device provides its own structural support rather than requiring separate components.
2Productivity
If the base plate surface is made smooth and closed for ground transport, then sliding efficiency is improved, but fastening capability deteriorates
Solution Approach 1:
The base plate has different surface characteristics in different areas: the outer surface is smooth and closed for efficient ground sliding, while the inner surface has retaining tabs with insertion openings that provide fastening capability. Each surface is optimized for its specific function.
3Ease of operation
If the base plate is rolled up in the longitudinal direction for transport, then portability is improved, but the structure becomes more compact
Solution Approach 1:
The base plate is designed to be rolled up in the longitudinal direction into a compact cylindrical form for transport. This curved configuration reduces the volume and makes the device portable while maintaining the functional structure when unrolled.

AI summary
According to the invention, a transporting means that can be pulled and carried has a flexible base plate (2), which is rolled up in the longitudinal direction in the transporting state and spread out flat for accommodating a load to be transported and raised at least on the longitudinal sides during use, such that the base plate has an approximately U-shaped cross-section, is provided with holes (5) for accommodating handles (8), belts (7), or strings at least along the two longitudinal edges (3) of the base plate (2). The center region forms the bearing surface (4) for an injured person, wherein retaining straps (9) are provided on the inside of the base plate (2) at least in the bearing surface (4) for the upper body of the injured person. The retaining straps each form an opening for feeding a transport aid (10, 11, 13) through.
