Elastic Exercise Device with Removable Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise devices lack adjustability and versatility for multiple exercises at various resistance levels, making them unsuitable for comprehensive workouts, especially for individuals who lack strength or have limited access to gym equipment.
Innovation Solution
A fitness device featuring a central handle with removably coupled rods and an elastic member, adjustable handles, and interchangeable weights, allowing for customizable resistance levels and multiple exercise configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional gym equipment is used, then resistance strength is sufficient for workouts, but the equipment is bulky and not portable
Solution Approach 1:
The exercise device is divided into separable components including a central handle, removable rods, and interchangeable weights. This segmentation allows the device to be disassembled into compact parts for easy transport while maintaining full functionality when assembled, resolving the contradiction between providing sufficient resistance strength and remaining portable.
2Ease of operation
If single-task exercise devices are used, then the device is simple and easy to use, but it lacks versatility for multiple exercises
Solution Approach 1:
The device incorporates a universal central handle that can accommodate multiple types of rods (first rod, second rod, third rod) and interchangeable weights. The resistance adjustment mechanism works across all configurations, allowing a single device to perform multiple exercise functions while maintaining ease of operation through consistent controls.
Solution Approach 2:
The device features adjustable components including movable resistance adjusters on the rods and interchangeable weight systems. These dynamic elements allow the device to adapt to different exercise requirements and resistance levels while maintaining a simple base structure, balancing versatility with ease of operation.
3Device complexity
If fixed resistance devices are used, then the device structure is simple, but it cannot accommodate different fitness levels
Solution Approach 1:
The device enables resistance adjustment through multiple mechanisms: changing the position of resistance adjusters along the rods, interchangeably mounting different weight values on the central handle, and selecting different rod configurations. These parameter changes allow adaptation to different fitness levels while adding only moderate complexity to the overall structure.
