Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recovery devices are often size-specific, time-consuming, and expensive, failing to provide comprehensive relief for both lumbar and knee issues, and are not suitable for individuals without joint or muscle complications.
Innovation Solution
A device with a main chassis, rotatable chassis, and tilt actuator, featuring upper and lower traction assemblies with linear actuators, allowing for adjustable sliding and rotational motions to facilitate lumbar and knee recovery maneuvers, controlled by a control unit with memory and processor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple size-specific devices are used to accommodate different body sizes and conditions, then the adaptability and versatility are improved, but the device complexity and cost increase
Solution Approach 1:
The patent applies universality by designing a single recovery device capable of performing multiple functions: lumbar traction, knee traction, and positioning for different body sizes. The device includes adjustable components such as movable armrests, adjustable footrests, and configurable traction mechanisms that can be repositioned to accommodate various users and treatment requirements, eliminating the need for multiple specialized devices
Solution Approach 2:
The patent implements dynamics through adjustable and movable components including linear actuators that enable dynamic positioning of the upper and lower traction assemblies. The rotatable chassis allows the device to transition between different operational positions, while sliding frames and movable armrests provide continuous adjustment capabilities, allowing the same device to adapt to different body sizes and treatment needs
2Reliability
If specialized devices are used for specific body areas, then the treatment effectiveness is improved, but the time required to switch between different devices increases
Solution Approach 1:
The patent merges multiple specialized functions into a single integrated device by combining lumbar traction mechanisms, knee traction mechanisms, and positioning systems in one unit. The upper traction assembly and lower traction assembly can be used sequentially or simultaneously on different body areas, eliminating the need to move between separate devices and reducing overall treatment time
Solution Approach 2:
The device uses dynamic reconfiguration through linear actuators and movable components to switch between different treatment modes. The rotatable chassis can be rotated to reposition the traction assemblies, and the sliding frames can be adjusted to accommodate different body areas, allowing rapid transition between lumbar, knee, or other treatment positions without requiring device replacement
3Adaptability or versatility
If existing recovery devices are used for areas not designed for them, then the versatility is improved, but the device complexity and cost increase
Solution Approach 1:
The patent designs a universal recovery device with standardized adjustable components that can be manufactured as a single integrated unit. The modular design with standardized connection points and adjustable mechanisms allows one device to serve multiple purposes for lumbar, knee, and other body areas, simplifying manufacturing compared to producing multiple specialized devices
Data Source
AI summary
A device for lumbar and knee recovery may include a rotatable chassis that may be mounted on a main chassis. An upper traction assembly and a lower traction assembly may be slidably mounted on the rotatable chassis and may provide two perpendicular translational degrees of freedom and a rotational degree of freedom. A patient may be positioned within the device and a control unit may be utilized for performing lumbar and knee recovery maneuvers by urging a plurality of actuators to activate the two translational degrees of freedom and the one rotational degree of freedom. Such activation of the degrees of freedom of the device may be carried out based at least in part on recovery and traction maneuvers stored on a memory of the device or received via a user interface unit from a user.
