Weighted Pelvic Tilt Trainer for Dynamic Gait Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercises for correcting anterior pelvic tilt often fail to effectively engage the necessary muscles during dynamic movement, leading to poor posture and chronic back pain, as they are typically performed in static positions.
Innovation Solution
A paddle-shaped exercise device strapped around the waist with a handle and rope connected to weights, which causes anterior pelvic tilt initially, prompting a natural compensation to walk upright and strengthen the appropriate muscles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If static exercises are performed to correct anterior pelvic tilt, then the pelvic alignment can be improved in a stationary position, but the muscles are not effectively engaged during dynamic movement leading to poor posture translation
Solution Approach 1:
The device transitions the user from static to dynamic movement by having them walk forward while pulling weights. The paddle-shaped device moves with the user's body during walking, providing continuous proprioceptive feedback during dynamic activity rather than requiring stationary exercises. This allows pelvic alignment training to occur during natural gait cycles.
Solution Approach 2:
The device leverages the user's natural compensatory mechanism - when the paddle pushes against the pelvic area creating anterior tilt, the user's body naturally compensates by walking more upright to counteract the pressure. This self-correcting mechanism trains the lumbo-pelvic-hip complex muscles during everyday movement patterns.
2Strength
If weights are attached to pull during walking, then the Lumbo-Pelvic-Hip Complex muscles are strengthened through dynamic movement, but the device initially causes increased anterior pelvic tilt that must be compensated for
Solution Approach 1:
The device applies a preliminary anterior pelvic tilt force through the paddle pressing against the pelvic area. This intentional harmful effect serves as a training stimulus that requires the user's lumbo-pelvic-hip complex muscles to activate and compensate, thereby strengthening these muscles through the act of counteracting the induced tilt during walking.
Solution Approach 2:
The device converts the harmful effect of increased anterior pelvic tilt into a beneficial training mechanism. By deliberately inducing anterior tilt through the weighted pull, the device creates a scenario where the user must engage their core and pelvic stabilizer muscles to maintain upright posture, thus transforming a postural deviation into a strength-building exercise.
3Loss of information
If a paddle-shaped device is strapped around the waist with weights, then proprioceptive input is provided during active movement, but the device complexity increases compared to simple static exercises
Solution Approach 1:
The device uses a flexible paddle-shaped component that straps around the user's waist and stomach area. This flexible design allows the device to conform to the body's contours during movement while maintaining the necessary structural integrity to deliver proprioceptive feedback through pressure against the pelvic area during walking.

AI summary
An exercise device and a method for its use to aid in the correction of Anterior pelvic tilt. A base has an upper support and a lower support. The base device is strapped around a user's stomach and connected to a rope. The rope passes through the user's legs and is attached to a weight holder behind the user. As the user walks forward, the weight holder is dragged along the floor and the force of the weights on the weight holder pressed the base against the user's stomach and aids in proper alignment of the pelvic region.
