Elastic Shoulder Support with Adjustable Tension Loops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoulder support devices are uncomfortable, unattractive, and ineffective in teaching proper posture as they fail to provide selective tension adjustment and often hinder natural movement, while most focus on stretching shoulders back without addressing the need to pull them downward and ignore individual shoulder slouching differences.
Innovation Solution
A shoulder support device featuring a flexible elastic continuous ring band with a slide that divides into laterally opposed arm receiving loops, allowing for adjustable tension distribution to cup the deltoid region and gently pull shoulders back and downward, enabling natural movement and selective tension adjustment for each shoulder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shoulder support devices use tight elastic bands to pull shoulders back, then posture correction effectiveness is improved, but comfort and skin irritation worsen
Solution Approach 1:
The device divides the shoulder support function into two separate adjustable loops, one for each shoulder. This segmentation allows independent tension adjustment for each shoulder, enabling effective posture correction while distributing tension more evenly to reduce skin irritation and discomfort.
Solution Approach 2:
The device uses adjustable slides on elastic bands that allow dynamic tension adjustment. Users can modify the tension level on each shoulder independently, enabling the device to adapt to different comfort levels and posture correction needs, thereby maintaining effectiveness while reducing harmful skin irritation.
2Ease of manufacture
If shoulder support devices provide uniform tension on both shoulders, then manufacturing simplicity is improved, but adaptability to individual shoulder differences worsens
Solution Approach 1:
The device is manufactured as a single continuous band with two separate loops and independent slides, maintaining manufacturing simplicity while enabling selective tension adjustment. The segmented loop design allows each shoulder to be adjusted independently without complicating the overall manufacturing process.
Solution Approach 2:
The device uses a universal design with identical loops and slides for both shoulders, simplifying manufacturing. However, the independent adjustability of each loop provides versatility, allowing the same device structure to adapt to individual differences in shoulder posture and tension requirements.
3Reliability
If shoulder support devices focus only on stretching shoulders back, then addressing forward slouching is improved, but comprehensive posture correction worsens
Solution Approach 1:
The device segments the posture correction function into two independent loops that can address different directional needs. Each loop can be adjusted to provide backward tension for forward slouching or downward tension for upward shoulder positioning, enabling comprehensive posture correction.
Solution Approach 2:
The adjustable slide mechanism allows dynamic reconfiguration of the tension direction and magnitude for each shoulder. This enables the device to adapt to various posture problems including forward slouching, upward shoulder positioning, and asymmetric posture issues, providing comprehensive correction capability.
4Reliability
If shoulder support devices are designed as medical or orthopedic apparatus, then functional effectiveness is improved, but aesthetic appeal and public wearability worsen
Solution Approach 1:
The device uses elastic bands that can be manufactured in various colors and patterns, transforming it from a clinical medical device into a fashionable accessory. The colorful bands worn over clothing improve aesthetic appeal while maintaining the functional effectiveness of posture support.
Solution Approach 2:
Instead of designing the device as a traditional medical apparatus worn under clothing, the invention inverts the approach by designing it to be worn over clothing as a visible fashion accessory. This maintains functional effectiveness while dramatically improving aesthetic appeal and public wearability.

AI summary
A shoulder support device includes a flexible elastic continuous ring band and a slide adjustably movable on the band that divides the band into a pair of loops defining arm receiving apertures that are cupped over the curved deltoid region of each shoulder of a wearer to pull the shoulders back and downward under tension to achieve a correct posture position. The slide is moveable to adjust tension distributed to the wearer's shoulders. When the slide is positioned midway between the shoulder blades at the back of the wearer, it provides equal distributed tension on both shoulders. Moving the slide more to the left or more to the right allows the wearer to selectively adjust which shoulder receives more tension.
