Biomechanical Exercise Machine with Adjustable Torso and Shoulder Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise machines fail to anatomically orient users in a biomechanically optimized position for targeting lower torso muscles, leading to increased risk of injury to the knee joints and lumbar spine while attempting to achieve comprehensive health and fitness.
Innovation Solution
A strength and fitness exercise machine with a main frame comprising a front support section, central support section, and rear support section, featuring an adjustable inclined upper torso support, shoulder support, and foot support assembly, which allows users to perform exercises in a biomechanically optimal range of motion, reducing joint stress and accommodating various body sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users perform leg exercises on conventional exercise machines, then they can target lower body muscles, but they risk injury to the knee joints and lumbar spine due to non-optimal anatomical positioning
Solution Approach 1:
The machine employs dynamic, adjustable support surfaces including an inclined upper torso support with cushioned pad, adjustable shoulder support, and foot support carriage that can be positioned along a declined path. These components allow the system to adapt to different user anatomies and exercise phases, maintaining biomechanically optimal positioning throughout the range of motion while reducing injury risk to the knee joints and lumbar spine
Solution Approach 2:
The machine changes key positioning parameters including the inclination angle of the upper torso support, the position of the shoulder support along the track assembly, and the position of the foot support along the declined path. These parameter adjustments enable customization to match individual user anatomy and optimize biomechanical alignment for safe and effective lower torso muscle targeting
2Adaptability or versatility
If exercise machines use fixed support structures, then they are simple in design, but they cannot accommodate various body sizes and optimize biomechanical positioning for all users
Solution Approach 1:
The support structure is divided into separate, independently adjustable segments: the upper torso support with cushioned pad on an inclined carriage, the shoulder support on a track assembly, and the foot support on a movable carriage. This segmentation allows each component to be adjusted independently to accommodate various body sizes and proportions, enabling comprehensive adaptability without requiring complete structural redesign
Solution Approach 2:
The machine employs universal adjustment mechanisms including the inclined upper torso support that can be positioned at different angles, the shoulder support that can be relocated along the track assembly, and the foot support that can be positioned along the declined path. These multi-functional adjustments allow a single machine design to serve users of various body sizes and types while maintaining biomechanical optimization
