Solution Overview

Problem

Low back pain affects a significant portion of the population, with existing exercise methods failing to effectively strengthen the lumbopelvic complex, leading to spinal instability and chronic pain.

Innovation Solution

An exercise machine with a stationary and rotating bench, adjustable resistance bar, and load arm mechanism that allows for linear and rotational adjustments, combined with various attachments such as inflatable hemispheres and swivel platforms, to provide progressive resistance and simulate exercises like planks, glute bridges, and bird-dogs, targeting the lumbopelvic core muscles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If existing exercise methods are used, then general trunk stabilization is provided, but the lumbopelvic core muscles are not effectively strengthened

Engineering Contradiction:

Improvestrength of lumbopelvic core musclesVSAvoideffectiveness for spinal stability

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The exercise machine incorporates a rotating bench that can be adjusted to various angles (α ranging from 90 to 210 degrees) relative to the stationary bench, allowing dynamic adjustment of exercise positioning to effectively target the lumbopelvic core muscles (multifidus and transverse abdominus) for spinal stability strengthening

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The machine allows modification of exercise parameters including bench angle (α), resistance magnitude, and resistance type (weight stack, resistance band, guided weight, or friction-based), enabling progressive overload and adaptive training to effectively strengthen the lumbopelvic core muscles

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If a fixed resistance system is used, then simple exercise execution is possible, but progressive resistance and varied exercise angles cannot be provided

Engineering Contradiction:

Improveadjustable resistance and anglesVSAvoidcomplexity of load arm mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The load arm mechanism serves multiple functions: it provides linear adjustment of the resistance bar position, rotational adjustment of the resistance bar orientation, and supports multiple resistance types (weight stack, resistance band, guided weight resistance, or friction-based resistance), making the machine versatile for various lumbopelvic strengthening exercises

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The resistance system is divided into separate adjustable components including the load arm mechanism with linear and rotational adjustment capabilities, allowing independent modification of resistance parameters to suit different exercise requirements and user needs

Inventive Principle:

Principle #1Segmentation

AI summary

An exercise machine is used to train the low back core musculature and lumbopelvic complex. The exercise machine can also be used to provide stability to the lumbar spinal column. The exercise machine includes a stationary bench substantially parallel to the floor and a rotating bench that is capable of rotating at an angle α about an axis, wherein the axis is located between the stationary bench and the rotating bench. A resistance means is used to adjust the amount of force required to move a resistance bar away from the rotating bench, while performing at least one of: a plank, a side plank, a bird-dog, a superman, a lumbar extension, a glute bridge, a single leg raise, a dual-leg raise, a bent leg raise, or a resisted push-up.
