Stretching Module Height Locking for Stable Joint Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The movable range of human joints decreases due to lack of exercise, injury, or aging, leading to increased joint injury risk and reduced motion function, necessitating a stretching apparatus that can accommodate individual physical characteristics and exercise purposes.
Innovation Solution
A stretching apparatus with a body frame, support frames, and an upward and downward adjustment module that is adjustable in height and rotatable within a certain angle range, featuring a guide slit, bearings, and a locking mechanism to allow for customizable stretching positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stretching apparatus uses a fixed structure, then the structural stability is maintained, but the adaptability to individual physical characteristics and exercise purposes deteriorates
Solution Approach 1:
The stretching apparatus employs adjustable components including a height adjustment mechanism that allows vertical positioning of the stretching member, and an angle adjustment mechanism that enables rotation within a certain angle range. These dynamic adjustments allow the apparatus to adapt to different user heights, body types, and exercise requirements without requiring multiple fixed structures.
Solution Approach 2:
The stretching apparatus is divided into independent adjustable modules: a height adjustment module with bearings and guide slits for vertical movement, an angle adjustment module with locking mechanisms for rotational positioning, and a stretching member that can be independently positioned. This segmentation allows each component to be adjusted separately to suit individual user needs.
2Adaptability or versatility
If the upward and downward adjustment module is made movable to adjust level, then the adaptability improves, but the stability of the stretching position deteriorates
Solution Approach 1:
The apparatus uses adjustable components including a height adjustment mechanism that allows vertical positioning of the stretching member, and an angle adjustment mechanism that enables rotation within a certain angle range. These dynamic adjustments allow the apparatus to adapt to different user heights, body types, and exercise requirements without requiring multiple fixed structures.
Solution Approach 2:
The locking protrusion and level adjustment groove mechanism enables users to pre-set and lock the stretching member at desired heights and angles before beginning exercise. Once positioned, the locking mechanism maintains the preset position stably throughout the exercise routine, preventing unwanted movement while allowing easy repositioning when needed.
3Ease of operation
If the stretching apparatus includes adjustment mechanisms, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The height adjustment mechanism utilizes gravity and friction through the bearing and guide slit arrangement to allow users to easily move the stretching member vertically without requiring additional power sources or complex controls. The locking protrusion automatically engages with the level adjustment groove to maintain position, eliminating the need for separate locking actuators.
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 apparatus enhances joint mobility and flexibility by providing adjustable stretching positions tailored to individual needs, improving joint range of motion and reducing injury risk.
Implementation Method 1
a first bearing located at each of both ends of the stretching member to be inserted into the guide slit, and a second bearing located at each of both ends of the stretching member to be inserted into the guide slit and configured to rotate around the first bearing as an axis within the guide slit when the upward and downward adjustment module rotates
Implementation Method 2
One of the stretching member and the level support may include a locking protrusion supported in a locking manner and configured to fix a level of the upward and downward adjustment module, and another one of the stretching member and the level support may include a level adjustment groove configured to support the locking protrusion

AI summary
A stretching apparatus includes a body frame including a pair of support frames extending in parallel in upward and downward directions at a certain interval and a connection frame connecting the pair of support frames, an upward and downward adjustment module that is movable in upward and downward directions to adjust a level thereof in the upward and downward directions between the pair of support frames and rotatable within a certain angle range based on the upward and downward directions, and a level support fixed to an inner side of each of the pair of support frames and configured to allow upward and downward movements of the upward and downward adjustment module or limit a downward movement of the upward and downward adjustment module depending on a rotation angle of the upward and downward adjustment module.
