Posture Brace Pull Cord Shoulder Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing posture correction braces lack adjustability to fit users of different heights and torso widths, often compromising comfort and effectiveness, particularly for individuals with posture-related medical issues like thoracic kyphosis, as they require manual adjustment or customization by a physician.
Innovation Solution
A posture correction brace featuring a pull cord mechanism that adjusts shoulder straps inferiorly along the back, allowing users to pull their shoulders back while wearing the brace, with adjustable shoulder straps and a belt system that includes a slider and pulley system for precise fitting, enabling users to adjust the fit without external assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size brace is used, then manufacturing and inventory are simplified, but it cannot fit users of different heights and torso widths
Solution Approach 1:
The patent applies dynamics by making the shoulder straps adjustable in length. The straps can be moved along the back of the brace from a first position to a second position, allowing the same brace to fit users of different heights and torso widths. This dynamic adjustment capability resolves the contradiction between maintaining a fixed brace structure and achieving adaptability for different users.
2Ease of operation
If shoulder straps are shortened at the front, then the front portion is adjustable, but the shoulders are pulled forward instead of back
Solution Approach 1:
The patent applies the inversion principle by moving the adjustment mechanism from the front of the shoulder straps to the back. Instead of shortening the front portion of the straps, users now adjust the strap length at the back by moving the straps along the back of the brace. This inverted approach ensures that the shoulders are pulled backward into proper alignment rather than forward, eliminating the harmful posture effect while maintaining adjustability.
3Ease of manufacture
If a rigid spinal frame with pre-drilled holes is used, then manufacturing is simplified, but adjustment requires removing the brace and drilling new holes
Solution Approach 1:
The patent applies dynamics by replacing the static, pre-drilled hole adjustment system with a dynamic system where shoulder straps can be continuously adjusted along the back of the brace. The straps can be moved to different positions without removing the brace or drilling new holes, allowing users to make adjustments quickly and conveniently while maintaining a relatively simple manufacturing process for the spinal frame.
4Manufacturing precision
If multiple sizes are produced, then fit accuracy is improved, but inventory complexity and cost increase
Solution Approach 1:
The patent applies the universality principle by designing a single brace model that can serve multiple users of different sizes through adjustable shoulder straps. The ability to move the straps along the back of the brace from a first position to a second position allows one brace to effectively replace multiple fixed-size models, simplifying inventory management while maintaining fit accuracy for different users.

AI summary
A posture correction brace for a person has a tightening mechanism that allows a user to pull a cord to pull down on the back of a pair of shoulder straps, thereby pulling the shoulders back to correct the person's posture. The front ends of the shoulder straps are typically also attached to the back of the wearer, to help the posture correction brace pull the shoulders back as the shoulder straps tighten.
