Solution Overview

Problem

Pelvic misalignment, often caused by leg length inequity or pre-existing pelvic misalignment, leads to body misalignment and pain, and existing treatments like muscle exercises are inadequate in providing effective alignment and pain relief.

Innovation Solution

A device with leg cups and straps that provide resistance during abductions and adductions to align the pelvis, utilizing a monolithic piece with specific strut and hole configurations to offer optimal resistance and elasticity, made from materials with a Young's Modulus of 7,000 MPa-15,000 MPa or 2,000 MPa-4,000 MPa, enhancing muscle engagement and alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If exercises are performed without resistance equipment, then the device complexity is reduced, but the effectiveness of muscle strengthening and pelvic alignment is insufficient

Engineering Contradiction:

Improvedevice complexityVSAvoideffectiveness of muscle strengthening

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent changes the physical parameters of the exercise by introducing resistance through springs. The spring constant and compression distance can be adjusted to modify the resistance level, transforming simple bodyweight exercises into resistance-based exercises that more effectively strengthen pelvic muscles for alignment.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The device acts as an intermediary between the user's legs, using springs as mechanical mediators to provide resistance during abduction and adduction movements. This intermediary mechanism enables effective muscle strengthening without requiring complex equipment.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If a rigid structure is used for the device, then the resistance provided is consistent, but the comfort and adaptability to different user leg positions is reduced

Engineering Contradiction:

Improvestructural stabilityVSAvoidadaptability to different leg positions

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The device transitions from a static rigid structure to a dynamic system with movable components. The springs can compress and extend, allowing the device to adapt to different leg positions and user anatomies while maintaining structural stability through the rigid frame.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The device is segmented into rigid structural components (frame, legs) and flexible functional components (springs, pads). This segmentation allows the rigid parts to provide stability while the flexible parts provide adaptability to different user configurations.

Inventive Principle:

Principle #1Segmentation

3Reliability

If multiple components are used to provide resistance and support, then the effectiveness is improved, but the manufacturing cost and device complexity increase

Engineering Contradiction:

Improveeffectiveness of pelvic alignmentVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The device uses multi-functional components that serve multiple purposes. For example, the spring-provided resistance serves both to strengthen muscles and to provide a measurable alignment reference. The footrests provide both support and positioning functionality, reducing the need for separate components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The present invention is a device for aligning a user's pelvis. The device may have a first end with a first end leg cup and a first end strap. A second end may be configured opposite the first end. The second end may have a second end leg cup and second end strap. A bridge may connect the first end and second end. The device may be placed between a user's legs whereby one of the user's legs is configured at least partially within the first end leg cup and the other of the user's legs is configured at least partially within the second leg cup. The user's legs may be secured to the device by the first end strap and second end strap. The user may perform a series of abductions and adductions whereby the device provides resistance to the user which aids in aligning the user's pelvis.
