Handheld Exercise Device With Rotating Disk And Tethers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise devices are either too heavy and bulky for portability or overly simplified, resulting in diminished effectiveness for users seeking a lightweight, portable, and efficacious physical workout.
Innovation Solution
A hand-held exercise device with a central disk and tethers that allows users to apply cyclic pulling forces to fatigue target muscle groups by rotating the disk, enabling effective exercise through various positions and movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional exercise devices are made heavy and bulky, then exercise effectiveness is improved, but portability deteriorates
Solution Approach 1:
The exercise device is segmented into a central disk component and multiple tether components that can be independently configured. The tethers can be attached to the disk at different locations (e.g., opposite sides vs. adjacent sides) to create different exercise configurations, allowing a single lightweight device to provide multiple exercise functions that would traditionally require multiple separate devices.
Solution Approach 2:
The device achieves multi-functionality through configurable tether attachments to the central disk. By attaching tethers to different locations on the disk, the same basic device structure can provide various exercise routines targeting different muscle groups, eliminating the need for multiple specialized heavy devices.
2Weight of moving object
If conventional exercise devices are simplified for portability, then device weight is reduced, but exercise effectiveness deteriorates
Solution Approach 1:
The device incorporates dynamic elements where the tethers can be attached to different locations on the central disk, creating variable resistance patterns and motion paths. This dynamic configurability allows the simplified lightweight device to adapt to different exercise requirements, maintaining effectiveness despite reduced weight and complexity.
3Adaptability or versatility
If multiple exercise functions are provided, then adaptability is improved, but device complexity increases
Solution Approach 1:
The device structure nests multiple exercise functions within a single central disk component. Rather than creating separate devices for different exercises, the tethers and their attachment configurations are nested within the basic disk structure, allowing multiple exercise routines to be contained within one simple device framework.

AI summary
A method of fatiguing a target muscle group of a user using an exercise device includes grasping in each hand one of a pair of outer handles of an exercise device, positioning the user's feet to be substantially aligned with the user's shoulders while maintaining the user's torso in a substantially upright orientation, positioning each hand in an initial position relative to the user's torso, cyclically pulling the outer handles away from one another in a cyclic motion to apply a cyclic pulling force to the tethers to cause the central disk to alternately rotate in opposing directions of rotation, and moving one or both hands to a secondary position relative to the user's torso and repeating the application of the cyclic force to fatigue the initial target muscle group or to fatigue a secondary target muscle group.
