Posture correction mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional posture correction machines are ineffective in correcting sitting posture while a user is reading or studying, as they do not accommodate the need for posture adjustment during these activities.
Innovation Solution
A posture correction mechanism with a housing, gearwheel, screw, and arm rests that allow for adjustable seating and arm positioning to correct kyphosis and lordosis, utilizing spring biasing members to facilitate movement and alignment of the user's posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional posture correction machines are used, then spinal alignment correction is achieved, but the device cannot be used during reading or studying activities
Solution Approach 1:
The arm rests are designed to be rotatable and adjustable, allowing the device to adapt to different user positions and activities. The arm rests can rotate between a first position for reading/studying and a second position for posture correction, enabling the device to serve multiple functions dynamically.
Solution Approach 2:
The device combines posture correction functionality with reading/studying support by providing arm rests that can serve both purposes. The arm rests act as supports during reading activities and as correction elements during posture correction, making the device universal for multiple uses.
2Adaptability or versatility
If fixed arm rests are used, then structural simplicity is maintained, but adjustable positioning for different activities is lost
Solution Approach 1:
The arm rests incorporate a rotation mechanism that allows them to move between fixed and adjustable positions. This dynamic capability enables the simple fixed structure to transform into an adjustable configuration when needed, providing adaptability without permanently increasing complexity.
Solution Approach 2:
The arm rest assembly is divided into separable components including the arm rest body, rotation mechanism, and connection elements. This segmentation allows the adjustable portion to be independently controlled while maintaining the simplicity of the overall structure.
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
Enables effective correction of abnormal spinal curvatures by allowing for adjustable seating and arm positioning, improving spinal alignment and preventing postural faults like humpback during reading or studying.
Implementation Method 1
The housing includes a spring biasing member engaged in the chamber of the housing and contacted and engaged with the screw for biasing and forcing the screw to move upwardly relative to the housing and the gearwheel.
Implementation Method 2
a screw engaged with the screw hole of the gearwheel and moveable up and down relative to the housing for driving the gearwheel to rotate relative to the housing
Implementation Method 3
a first gear rotatably attached to the carrier and engaged with the gearwheel, the first gear being connected to the first shaft for allowing the first gear and the first shaft to be driven by the gearwheel to rotate
Implementation Method 4
a first gear rotatably attached to the carrier and engaged with the gearwheel, the first gear being connected to the first shaft for allowing the first gear and the first shaft to be driven by the gearwheel to rotate relative to the carrier and the housing, a second gear rotatably attached to the carrier and connected to the second shaft, and a pinion engaged with the gearwheel and the second gear for allowing the second gear and the second shaft to be rotated and driven
