Modular Care Device With Motorized Repositioning And Muscle Stretching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients suffering from paralysis or trauma and requiring long-term bed rest face challenges such as bedsores, muscle atrophy, and difficulty in repositioning due to the lack of adjustable and muscle-stretching functions in traditional nursing beds, which increases nursing workload and discomfort.
Innovation Solution
A multifunctional care device comprising three functional parts: a first part with a main body frame, a second part with movable plates and a supporting rod, and a third part with driving devices, allowing for adjustable positioning and muscle stretching through combined use of these parts, including motors, reels, and guide rails for positional adjustment and user transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional nursing bed is used for long-term bedridden patients, then the patient can be kept in bed, but the patient is prone to bed sores and muscle atrophy due to lack of position adjustment and muscle stretching functions
Solution Approach 1:
The nursing bed is divided into multiple functional modules: a lifting mechanism with suspension pads for position adjustment, a stretching mechanism with elastic components for muscle exercise, and a base frame structure. Each module can independently perform its function, allowing the system to address multiple care needs simultaneously while maintaining structural organization.
Solution Approach 2:
The nursing bed integrates multiple functions into a single device: it provides position adjustment through the lifting mechanism, muscle stretching through the elastic bands and handles, and support for bedridden patients. This multi-functional design eliminates the need for separate exercise equipment and positioning devices, directly resolving the adaptability limitation of traditional nursing beds.
2Ease of operation
If manual turning is used for heavy patients, then the patient can be repositioned, but the medical staff consume much energy and the work becomes difficult
Solution Approach 1:
The manual mechanical turning operation is replaced with an automated lifting mechanism that uses a motor-driven reel system. The suspension pads are lifted and repositioned automatically through the winding and unwinding of ropes on rotating reels, eliminating the need for staff to manually lift and turn heavy patients, thereby significantly reducing energy consumption.
Solution Approach 2:
The lifting mechanism enables the patient to be repositioned with minimal human intervention. The motorized system performs the heavy lifting and positioning work autonomously, allowing medical staff to simply operate the control mechanism rather than physically exerting themselves to move the patient.
3Adaptability or versatility
If traditional nursing bed without stretching function is used, then the structure is simple, but the practicability is restricted and brings troubles to the user
Solution Approach 1:
The stretching function is merged with the existing nursing bed structure by integrating elastic bands into the frame and attaching handles to the suspension pads. This combination allows the bed to provide both support and therapeutic stretching without requiring entirely separate equipment, thus adding functionality while controlling complexity.
Solution Approach 2:
The stretching mechanism uses elastic bands that can dynamically adjust to different patient needs and positions. The elastic components provide variable resistance and adaptability, allowing the same structural element to serve multiple stretching purposes for different muscle groups without requiring complex mechanical adjustments.
