Dual-Mechanism Exercising Device for Circular and Elliptical Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise equipment often requires users to switch between different devices to achieve a variety of aerobic exercises, leading to inefficiencies in gym usage and the need for multiple devices at home, as they typically offer either circular or elliptical motion, not both, limiting user engagement and space utilization.
Innovation Solution
A device with a mechanism allowing for both circular and elliptical movement of the footrest, utilizing synchronized main and secondary wheels connected by rods that change position based on user input, enabling smooth transitions between exercise types and adjustable movement parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users switch between different exercise devices to achieve variety in aerobic exercises, then muscle group diversity is improved, but time loss due to waiting and device switching increases
Solution Approach 1:
The patent combines stationary bicycle and elliptical exercise functions into a single device by integrating both circular pedaling mechanism and elliptical footrest motion capability, allowing users to perform multiple exercise types without switching devices
Solution Approach 2:
The exercising device is designed with universal functionality to perform both stationary bicycle exercises (circular motion) and elliptical exercises (elliptical motion) through a single multi-functional machine, eliminating the need for multiple separate devices
2Adaptability or versatility
If multiple exercise devices are purchased for home use to achieve exercise variety, then adaptability is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent merges stationary bicycle and elliptical exercise machines into one unified device, reducing the number of separate devices needed from two to one while maintaining full exercise variety
Solution Approach 2:
The device achieves multi-functionality by incorporating both circular pedaling and elliptical motion capabilities in a single machine, eliminating the need for multiple specialized devices in home gyms
3Adaptability or versatility
If multiple exercise devices are allocated in gym aerobic area, then exercise variety is improved, but space utilization efficiency decreases
Solution Approach 1:
The patent combines the functions of stationary bicycle and elliptical machines into one device, reducing the total equipment footprint in gym aerobic areas while maintaining exercise variety options
