Guided Movement Exercise Machine with Dynamic Motion Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise machines fail to provide a stimulating and effective full-body workout, leading to monotony, discomfort, and limited muscle engagement, particularly lacking in eccentric contractions and natural movement patterns, which can result in excessive strain and injury.
Innovation Solution
The exercise machine incorporates a motor-driven system with adjustable foot stands and hand grips that move along pre-set paths, allowing for guided, dynamic movements that simulate natural motions such as squatting, stair-stepping, and rowing, enabling full extension of limbs and varying intensity levels to engage core muscles and promote cardiovascular exercise with reduced impact on joints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional exercise machines use fixed circular/elliptical motion paths, then the machine structure is simple, but the movement is unnatural and causes excessive strain on joints
Solution Approach 1:
The exercise machine uses a motor-driven system with adjustable foot stands and hand grips that move along pre-set paths, allowing the motion characteristics to be dynamically adjusted to simulate natural movements such as squatting, stair-stepping, and rowing, rather than being constrained to fixed circular/elliptical paths
Solution Approach 2:
The machine enables variation in motion parameters including path shape, speed, and range of motion to accommodate different exercise modes and user needs, transforming the fixed motion parameter into an adjustable one that can adapt to natural movement patterns
2Adaptability or versatility
If conventional exercise machines constrain range of motion, then the machine structure is simple, but muscle groups are not sufficiently stretched and exercised
Solution Approach 1:
The motor-driven system dynamically adjusts the range of motion for foot stands and hand grips throughout the exercise cycle, enabling full extension of limbs and varying intensity levels to engage core muscles, rather than constraining to a limited fixed range
Solution Approach 2:
The machine pre-sets optimal motion paths that guide the user through complete ranges of motion including full limb extension, ensuring muscles are adequately stretched and exercised before the user becomes fatigued or adopts poor posture
3Adaptability or versatility
If conventional exercise machines lack external driving force, then the machine structure is simple, but eccentric muscle contractions are not provided
Solution Approach 1:
The motor acts as an intermediary driving force that guides the user's movements, providing the external force needed to produce eccentric muscle contractions during the exercise cycle, particularly during the upward phase of leg movement and pulling phase of arm movement
Solution Approach 2:
The motor-driven system creates periodic cycles of guided movement that alternate between user-initiated concentric contractions and machine-guided eccentric contractions, providing a comprehensive muscle workout that includes both contraction types
4Object-affected harmful factors
If conventional exercise machines require forced circular motion, then the machine structure is simple, but ankles, knees, and hips experience excessive strain and damage
Solution Approach 1:
The guided motion system dynamically adjusts the movement path to follow natural anatomical alignment, reducing excessive strain on ankles, knees, and hips by avoiding forced circular motions that contradict natural joint mechanics
Solution Approach 2:
The machine pre-configures motion paths that prevent harmful joint strain before it occurs, guiding users through movements that maintain proper joint alignment and reduce impact forces, rather than allowing harmful strain to develop and then correcting it
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The machine provides a comprehensive workout that combines cardiovascular exercise, dynamic stretching, and strength training, reducing the risk of injury while effectively engaging major muscle groups, improving muscle tone, and enhancing flexibility and range of motion.
Implementation Method 1
The exercise machine incorporates a motor-driven system with adjustable foot stands and hand grips that move along pre-set paths
Implementation Method 2
a first platform arm pivotally connected to the frame about a first pivot joint proximate to the front end of the frame to flex and extend at least a portion of the lower body

AI summary
An exercise machine can include a frame, one or more platform arms that can be driven by a motor or a hydraulic system, and one or more handle arms that can be grasped by the user's hands. The exercise machine can guide the user through movement that actively flexes and extends portions of a user's body while the user exercises to provide, for example, dynamic stretching and cardio benefits while achieving strength training.
