Solution Overview

Problem

Existing devices fail to adequately address pain and discomfort caused by friction and pressure in the coccyx and sacral areas during seated core exercises, such as sit-ups and abdominal crunches, due to inadequate distribution of load and lack of contoured support, leading to prolonged healing times and reduced fitness activity.

Innovation Solution

A lumbar support device with a posterior support and recess, providing a concave curvature to reduce pressure and friction, and a convex contoured lumbar support to match the natural curvature of the spine, along with a void to alleviate contact pressure near the coccyx and sacral areas, allowing for a more distributed support and reduced skin-on-skin interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a flat support surface is used, then the device structure is simple, but it creates concentrated loads and fails to distribute the user's body weight adequately, causing pain and discomfort in the coccyx and sacral areas

Engineering Contradiction:
Improvedevice structure simplicityVSAvoidconcentrated loads and pressure pain
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The support device incorporates a contoured surface with a concave depression that matches the natural curvature of the human posterior region. This curved geometry distributes the user's body weight across a larger surface area, eliminating concentrated loads on the coccyx and sacral areas while maintaining structural integrity and comfort during seated core exercises.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Reliability

If conventional lumbar support devices are used, then they provide basic lumbar curvature support, but they fail to address skin-on-skin friction and pressure in the coccyx and sacral areas, leading to discomfort and prolonged healing times

Engineering Contradiction:
Improvelumbar support functionVSAvoidskin friction and pressure pain
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The support device is divided into distinct functional zones: a lumbar support region that maintains proper spinal curvature, and a posterior support region with a concave depression that specifically addresses the coccyx and sacral areas. This segmentation allows each region to perform its specialized function independently, providing comprehensive support while eliminating harmful friction and pressure points.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The contoured posterior support acts as an intermediary between the user's body and the exercise surface. By introducing this specially shaped support structure, the device mediates the interaction between the user and the ground, distributing pressure and reducing skin-on-skin friction in the problematic coccyx and sacral areas during seated core exercises.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If repetitive abdominal exercises are performed on a flat surface, then the exercise effectiveness is maintained, but friction and pressure in the lower spinal regions cause skin irritation, scabbing, and scarring that delay rehabilitation

Engineering Contradiction:
Improveexercise effectivenessVSAvoidhealing time and activity interruption
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The contoured support device provides preemptive protection by distributing pressure and reducing friction before skin irritation can occur. The concave depression in the posterior support area cushions the coccyx and sacral regions during repetitive abdominal exercises, preventing the development of painful conditions that would otherwise require extended healing time and interrupt rehabilitation progress.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

The preferred embodiment of the invention provides relief from pressure, increased friction and skin-to-skin interaction, particularly in the lower lumbar, sacral and coccyx areas to a person exercising when performing Seated Core Exercises by means of a lumbar support and posterior support. Said posterior support is preferably further characterized by a recess or void to provide pressure relief in the region near the user's posterior proximal to the coccyx and sacral areas.
