Motorized Stretching Device with Rotational Hip Joint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stretching devices fail to provide effective, portable, and adjustable stretching for various muscle groups, particularly the hamstring muscle group, often requiring user effort, causing strain on users with back problems, and lacking in range of motion, portability, and compactness.
Innovation Solution
A portable and adjustable stretching device with a motorized system that allows for multiple angles and orientations, including rotational movement at the hip joint, enabling various stretches for muscle groups like hamstrings, glutes, inner thighs, calves, and quadriceps, with a support base and motor assembly that can be easily repositioned and controlled via a remote device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual stretching devices are used, then users can perform stretching exercises, but users must exert their own energy and strength which causes strain particularly for users with back problems
Solution Approach 1:
The patent replaces the manual mechanical stretching system with an automated motorized system. The motor assembly performs the stretching motion automatically, eliminating the need for users to exert physical effort or strain their bodies to perform the stretching exercise.
Solution Approach 2:
The stretching device performs the stretching action autonomously without requiring user effort. The motorized system self-regulates the stretching motion, positioning, and duration, allowing the device to serve itself rather than requiring the user to actively participate in the mechanical action.
2Adaptability or versatility
If stretching devices are designed for specific muscle groups, then they can provide targeted stretching, but multiple separate devices are needed for different body parts
Solution Approach 1:
The patent designs a universal stretching device with a motor assembly and adjustable support members that can accommodate multiple body parts including legs, feet, ankles, and other extremities. The device provides targeted stretching for different muscle groups through a single multi-functional apparatus rather than requiring separate devices for each body part.
Solution Approach 2:
The stretching device incorporates adjustable and reconfigurable support members that can be positioned at various angles and orientations. This dynamic adjustability allows the same device structure to adapt to different stretching requirements for various muscle groups and body parts.
3Weight of moving object
If stretching devices are made portable and compact, then they can be easily stored and transported, but they may lack the stability and range of motion for effective stretching
Solution Approach 1:
The stretching device is divided into modular components including a motor assembly, adjustable support members, and a base structure. This segmentation allows the device to be compact and portable while maintaining structural integrity and effectiveness when assembled for use.

AI summary
An apparatus and method for use of an improved stretching device providing various stretches and manipulation of a user's muscle groups, including lower body muscle groups. Movement of the upper and lower support members can be achieved with a controller or wireless controller, such as a cellular phone executing an application operatively connected via a transceiver of the stretching device. The upper support member and lower support member may be independently controlled by a secondary motor assembly at a rotational connection between the support members. Some embodiments may provide removable support members for switching between left and right-side manipulation of a user's left and right legs with a single device. Other embodiments may include a track to allow for a sliding movement of the motor assembly or the upper and lower support members between left and right sides of the stretching device.
