Solution Overview
Problem
Existing exercise cycles are often too large, heavy, or restrictive in terms of resistance range and portability, making them unsuitable for many users who lack access to suitable exercise equipment or prefer versatile and compact options.
Innovation Solution
A portable rotary motion exercise device with a flexible connection to the user, utilizing multiple wraps of a band around a shaft for rotational resistance, which can be adjusted by tension mechanisms, and a support system that includes a flexible apparatus for secure use on various surfaces, allowing for compact storage and versatile exercise configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid connection between the exercise cycle and the user or chair is added, then stability and support are improved, but size and weight increase making it harder to transport or store
Solution Approach 1:
The patent uses a flexible band instead of a rigid connection to attach the exercise cycle to the user or chair. The band provides sufficient stability and support while being lightweight and collapsible, allowing the device to be easily transported or stored without requiring a heavy rigid frame.
Solution Approach 2:
The connection system is divided into separate components: the flexible band, the attachment points on the exercise cycle, and the attachment points on the user or chair. This segmentation allows each component to be optimized independently, with the band providing flexibility and the attachment points providing secure connection without requiring a monolithic rigid structure.
2Adaptability or versatility
If a larger device for producing pedaling resistance is used, then resistance range and selection ease are improved, but weight and size increase
Solution Approach 1:
The patent changes the parameter of resistance production from a large stationary device to a flexible band system wrapped around the crankshaft. By adjusting the number of wraps and tension on the band, a wide range of resistance levels can be achieved without requiring a large device, thus reducing weight while maintaining versatility.
Solution Approach 2:
Instead of increasing resistance through a larger spatial footprint, the patent achieves variable resistance by changing the dimensional parameters of the band wraps around the crankshaft. Multiple wraps of the band create a compact resistance mechanism that provides a wide resistance range without increasing the overall size or weight of the device.
3Adaptability or versatility
If multiple wraps of a band around a shaft are used for rotational resistance, then resistance range is improved, but device complexity increases
Solution Approach 1:
The band wrap system is designed to be self-adjusting and self-regulating. The flexible band naturally maintains tension and provides consistent resistance without requiring complex control mechanisms. Users can easily adjust resistance by modifying the number of wraps or tensioning the band, making the system simple yet versatile.
Solution Approach 2:
The flexible band acts as an intermediary element between the crankshaft and the resistance mechanism. Instead of directly attaching resistance components to the shaft, the band mediates the connection, allowing for multiple wraps and variable tension while maintaining a simple overall structure that is easy to manufacture and operate.
