Hinged Vaginal Strengthening Device with Adjustable Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for strengthening pelvic floor musculature in women often fail to accurately recruit the desired muscles, leading to asymmetry and dysfunction, and do not provide optimal stabilization or closure, potentially causing bladder and urethral irritation, and are not customizable to individual anatomy.
Innovation Solution
A device with elongated semi-round primary arms and secondary arms connected by hinges, featuring adjustable resilient members and a handle, designed for vaginal insertion to promote both horizontal and vertical closure, customizable in diameter and resistance to target the three distinct layers of the pelvic floor musculature without overpowering weaker muscles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If flat closure devices are used to strengthen pelvic floor musculature, then the device structure is simple, but the stability and closure effectiveness are reduced by nearly 66%
Solution Approach 1:
The patent applies spheroidality by designing the device with a curved, ovoid shape that matches the natural anatomy of the vaginal canal and pelvic floor. The curved surface area of the device conforms to the cylindrical and ovoid structures of the vaginal canal and rectum, enabling optimal contact and closure effectiveness without requiring complex multi-surface designs. This curved geometry allows the device to provide stable vertical closure while maintaining structural simplicity.
2Device complexity
If devices promote outward pushing movement of the vagina, then the device structure is simple, but the device puts pressure on the bladder and urethra causing irritation and pain
Solution Approach 1:
The patent inverts the conventional approach by promoting inward and upward closure movement instead of outward pushing. The device is designed to be inserted into the vaginal canal and rotated to engage the pelvic floor musculature, creating an inward and upward closing force that stabilizes the pelvis and urogenital structures without exerting pressure on the bladder and urethra. This inverted mechanism eliminates the harmful irritation and pain associated with outward pushing devices.
3Ease of manufacture
If devices use fixed resistance and dimensions, then the device manufacturing is simple, but the device cannot be customized to individual user needs and anatomy
Solution Approach 1:
The patent applies dynamics by designing the device with adjustable resistance mechanisms and customizable dimensions. The device incorporates interchangeable resistance components that can be adjusted to match individual user needs and anatomical variations. The device dimensions and resistance levels can be modified to accommodate different stages of pelvic floor recovery, allowing the same basic device structure to adapt to various user requirements without requiring custom-manufactured versions for each user.
4Device complexity
If devices are designed for global contraction of pelvic floor musculature, then the device structure is simple, but the stronger musculature overrides the weaker musculature perpetuating asymmetry and dysfunction
Solution Approach 1:
The patent applies local quality by designing the device with multiple resistance axes positioned at different locations along the device length. Each resistance axis provides targeted resistance to specific segments of the pelvic floor musculature, allowing localized strengthening rather than global contraction. This distributed resistance system ensures that weaker muscle segments receive appropriate challenge while stronger segments are not overloaded, preventing the override effect and promoting balanced muscle activation across the entire pelvic floor.
Applied Scientific Principles

Function Achieved in This Case
The device effectively strengthens the pelvic floor musculature, reducing vaginal gapping, improving bladder control, and enhancing orgasmic potential by providing adjustable resistance and customizable fit, suitable for various user needs and anatomies, thereby addressing the limitations of existing devices.
Implementation Method 1
resilient members between the semi-round primary arms. Repeated use of this device, by contracting and relaxing the associated musculature, increases pelvic floor health.

AI summary
A hinged vaginal strengthening device has three points of resistance along its length, which correspond with the three layers of pelvic musculature. The device is inserted into a vagina and compressed by the pelvic floor musculature, in accordance with various regimens to achieve goals such as decreasing vaginal gap or overcoming painful intercourse. The device can be of various dimensions, and various compression resiliencies thereby allowing a user to progress through multiple steps to achieve their goal of increasing or decreasing their vaginal space, as well as increasing muscle tone.
