Stand-up Abdominal Exercise Device with Adjustable Knee and Ankle Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current exercise devices for abdominal and back muscles often exacerbate lower back pain due to inadequate foot anchors, friction, and over-reliance on the device for support, leading to discomfort and ineffectiveness in strengthening muscles.
Innovation Solution
A stand-up abdominal/back muscle exercise device with adjustable ankle and knee supports, featuring a t-bar and telescoping shafts for secure ankle positioning, and a knee radial pivot lock bracket for customizable leg support, allowing users to perform gentle, effective exercises without floor contact, focusing on body weight for muscle strengthening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If floor-based exercises are used to strengthen abdominal and back muscles, then muscle strengthening can be achieved, but lower back pain and friction on contact areas increase
Solution Approach 1:
The patent introduces an intermediary device (the exercise machine with support structures) between the user and the floor. The machine provides support surfaces and anchor points that eliminate the need for direct floor contact, thereby reducing friction and pressure on the lower back while still enabling effective abdominal and back muscle exercises through controlled body weight movement.
Solution Approach 2:
The patent transitions the exercise from a horizontal floor-based planar motion to a vertical standing-based three-dimensional motion. By supporting the user in a standing position with adjustable support surfaces, the exercise utilizes vertical body weight and range of motion, changing the dimensional orientation of the exercise and thereby reducing harmful friction on the lower back while maintaining muscle strengthening effectiveness.
2Ease of operation
If floor-based exercises are used, then abdominal and back muscles can be exercised, but inadequate foot anchors cause friction and discomfort
Solution Approach 1:
The machine provides intermediary support surfaces (foot rests, back supports, and anchor points) that replace direct floor contact. These support surfaces are designed with appropriate cushioning and contact areas to distribute pressure, eliminating the friction and discomfort caused by inadequate foot anchors on the floor while maintaining ease of operation.
3Object-affected harmful factors
If device-based exercises are used to avoid floor contact, then friction and back pain are reduced, but device complexity and cost increase
Solution Approach 1:
The exercise machine is divided into separate functional modules: support surfaces for the body, adjustable support surfaces for positioning, anchor points for stability, and control mechanisms for adjustment. This segmentation allows each component to perform its specific function independently, simplifying the overall design and reducing complexity while still achieving the goal of eliminating floor contact and reducing friction and back pain.
