Multifunctional Hospital Bed Transforming Into Standing Aid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hospital beds for rehabilitation are highly specialized, complex, and bulky, limiting their use in home rehabilitation and hospital wards with space constraints, and lack the ability to transform into standing aids, leading to inefficiencies and increased complexity in operation and maintenance.
Innovation Solution
A multifunctional hospital bed that can be transformed into a standing aid using standard fittings, featuring a C-shaped frame with adjustable support struts and a flexible pulling cable system, allowing for bidirectional stretching and rotation, and incorporating electric lift and power struts for therapeutic exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If highly specialized hospital beds are used for rehabilitation, then therapeutic effectiveness is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines a hospital bed and standing aid into a single multifunctional device. The bed frame serves as the base structure for both lying/sitting functions and standing assistance functions, eliminating the need for separate specialized devices while maintaining therapeutic effectiveness.
Solution Approach 2:
The invention merges previously separate devices (hospital bed and standing aid) into one integrated system. The support struts, pulling cable system, and bed frame work together to provide both bed functions and standing assistance, reducing overall device complexity and space requirements.
2Reliability
If highly specialized hospital beds are used for rehabilitation, then therapeutic effectiveness is improved, but space requirements and availability increase
Solution Approach 1:
The multifunctional device allows a single piece of equipment to serve multiple therapeutic purposes (rehabilitation exercises, standing assistance, body positioning), thereby reducing the total space needed in hospital wards or home rehabilitation settings while maintaining comprehensive therapeutic capabilities.
3Reliability
If complex specialized beds are used, then rehabilitation capabilities are improved, but ease of operation and patient independence decrease
Solution Approach 1:
The standing aid function enables patients to assist themselves in transitioning from sitting to standing position using the support struts and pulling cable system, reducing dependence on healthcare staff and improving patient independence in their rehabilitation process.
4Adaptability or versatility
If separate specialized devices are used for bed and standing aid functions, then functional specificity is improved, but device complexity and maintenance requirements increase
Solution Approach 1:
The patent creates a single device that performs both bed functions and standing aid functions, eliminating the need to maintain multiple separate specialized devices. The integrated design reduces maintenance complexity while preserving the specific therapeutic capabilities of each function.

AI summary
The invention relates to the field of medical technology, and more particularly to multi-functional hospital beds. The claimed structure comprises a vertical stand in the shape of an inverted L, which is connected to a folding bed. The bed has two sections, one of which can be folded onto the other, whereupon both sections can be folded to the vertical stand. A movable frame is disposed in the top corner of the stand, wherein said frame can be fastened in two positions: to the top part of the stand, and also at an angle of 45 degrees to the stand. A motor is provided, which pulls a cable. Said cable passes through the stand and the end of the movable frame. This provides two operating modes: Mode 1 is that of a bed. In this case, the frame is fastened to the stand, and the bed is unfolded. Traction or fixation can be applied to individual parts of a patient's body. Mode 2 is that of a standing aid. In this case, the bed is folded, and the frame is positioned at an angle of 45 degrees. The legs of the bed form a support, and the patient can be verticalized with the aid of the cable and a harness. The invention is simple and universal and is also capable of replacing several pieces of hospital equipment at once.
