Slip Training Device with Movable Platforms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current physical therapy methods lack effective equipment to train individuals with spinal cord injuries or the elderly to prevent slip-related falls, as there is no device that can create standardized perturbations at the foot or simulate slipping while controlling parameters.
Innovation Solution
A slip training device comprising a frame with movable platforms and rotatable elements that mimic slipping by allowing platforms to move unpredictably, replicating the experience of slipping on a slippery surface, thereby engaging muscles responsible for balance and improving control over the center of mass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If perturbation training is applied using external pushes at the trunk, shoulder, or upper leg, then reactive balance responses can be elicited, but the training cannot simulate slipping conditions at the foot level
Solution Approach 1:
The device segments the perturbation application by providing multiple independent platforms at different locations (foot level, knee level, shoulder level, trunk level) that can be independently configured as movable or stationary. This allows selective activation of specific body segments for balance training while addressing the limitation of only pushing at upper body locations.
Solution Approach 2:
The device introduces dynamic elements by making certain platforms movable along the frame while keeping others stationary. The movable platforms can be positioned at various locations and allow slipping motion when activated, creating realistic slip conditions at the foot level that were previously impossible to simulate with static push-based training devices.
2Reliability
If standardized perturbation parameters are implemented, then training consistency is improved, but device complexity increases
Solution Approach 1:
The device enables parameter standardization by allowing precise control over perturbation characteristics including platform position along the frame, platform mass, friction coefficients between platform and user footwear, and the degree of platform mobility. These adjustable parameters provide consistent, repeatable training conditions while the modular design keeps complexity manageable.
3Adaptability or versatility
If multiple platforms with different configurations are provided, then training versatility is enhanced, but device complexity increases
Solution Approach 1:
The device achieves multi-functionality through a modular platform design where each platform can be independently configured as movable or stationary, positioned at different locations along the frame, and adjusted to different masses. This universal platform architecture allows a single device to provide multiple training configurations (foot-level slip, knee-level perturbation, shoulder-level push, trunk-level balance) without requiring separate equipment for each training type.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively trains individuals to enhance their reactive balance responses and reduce the risk of slip-related falls by simulating slipping conditions, improving their ability to maintain balance and control their center of mass within their base of support.
Implementation Method 1
rotatable elements disposed below the at least platform... The rotatable elements allow the movement of the at least one platform along the frame
Data Source
AI summary
The present disclosure is directed to a slip training device. The training device comprises an outer frame having two ends; a plurality of platforms disposed on the outer frame, and at least one rotatable element disposed below each platform for enabling the movement of the platform with respect to the frame. Each platform is configured to be either movable along the frame or stationary with respect to the frame. In use as a slip training device, a user steps on one end of the device and walks across the device, not knowing whether a platform is moveable or stationary. If the user steps on a moveable platform, then the user will need to use balance to prevent a fall. If the user steps on a stationary platform, then the user can walk across that platform normally. Whether a particular platform is moveable or stationary can be changed each time the user traverses the device.
