Hanging Seat Training Device for Fall Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Treadmills designed for physical medicine and rehabilitation often pose a risk of users, especially the elderly or those with weakened strength, falling due to difficulty matching their slower steps with the conveyor belt speed.
Innovation Solution
A training device incorporating a conveyor belt with a hanging seat and adjustable frame and handrail mechanisms, featuring elastic belts and step sensors, to provide support and stability for users, allowing them to walk or run safely and adjustably.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the conveyor belt speed is increased to improve training effectiveness, then the training efficiency is improved, but the safety of weak users deteriorates as they cannot match their steps with the belt speed
Solution Approach 1:
The patent applies beforehand cushioning by providing a hanging seat that can support the user's weight before a fall occurs. The seat is positioned to catch the user if they stumble or cannot keep up with the belt speed, preventing injuries from falling to the ground. This safety mechanism allows the conveyor belt to operate at higher speeds for better training efficiency while maintaining user safety through the pre-positioned protective support.
2Ease of operation
If the conveyor belt speed is reduced to match the steps of wounded, elderly, or ill people, then the ease of operation is improved, but the training effectiveness deteriorates due to slower speed
Solution Approach 1:
The patent applies dynamics by making the supporting mechanism adjustable and adaptable to different user needs and progression levels. The hanging seat can be adjusted in position and support level, allowing users to start with lower belt speeds and more support, then progressively increase speed and reduce support as they strengthen. This dynamic adjustment resolves the contradiction by enabling both slow speeds for ease of operation and faster speeds for training effectiveness at different stages.
Solution Approach 2:
The hanging seat provides beforehand cushioning that gives users confidence to walk at various speeds. Knowing they have safety support allows them to attempt faster paces for better training effectiveness while the seat catches them if they slow down too much. This enables users to push their limits safely rather than being constrained to very slow speeds.
3Reliability
If a hanging seat is added to provide safety support, then the user safety is improved, but the device complexity increases
Solution Approach 1:
The patent uses an intermediary approach by employing simple belts and a basic frame structure to create the hanging seat, rather than complex mechanical support systems. The belts serve as intermediaries between the user and the frame, providing safety support through a simple, lightweight structure that adds minimal complexity while effectively preventing falls.
4Adaptability or versatility
If adjustable handrails and extendable sticks are added to enhance support and adaptability, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the support structure into separate, independently adjustable components: extendable vertical sticks, adjustable handrails, and a hanging seat. Each component can be adjusted separately to suit different user heights and support needs. This modular segmentation provides high adaptability while keeping each individual component relatively simple, avoiding the need for a complex integrated adjustment mechanism.
