Solution Overview
Problem
Conventional pull exercise training devices, such as rowing machines, typically offer only a single source of resistance, limiting user experience and the ability to adjust load forces for varying levels of training.
Innovation Solution
A pull exercise training device incorporating a frame with a reel, mainspring, flywheel, one-way clutch, generator set with magnets, and a control circuit, allowing for multiple resistance sources including inertia, wind, and adjustable magnetic resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single source of resistance (flywheel, fan wheel, or pneumatic rod) is used in conventional rowing machines, then the device structure remains simple, but the user experience is limited and load force adjustment for different training levels is not possible
Solution Approach 1:
The resistance system is segmented into three independent resistance sources: a flywheel for inertia resistance, a fan wheel for wind resistance, and a pneumatic rod for pressure resistance. Each resistance source can be independently selected and adjusted, allowing users to customize their training experience while maintaining manageable structural complexity through modular design
Solution Approach 2:
The resistance mechanism is designed with multi-functionality, where a single resistance system can provide three different types of resistance forces (inertia, wind, and pressure) depending on the selected configuration. This universal design allows the device to adapt to different training levels and user preferences without requiring separate equipment for each resistance type
2Adaptability or versatility
If multiple resistance sources are integrated into the rowing machine, then load force adjustment for different training levels becomes possible, but the device structure becomes more complex
Solution Approach 1:
The resistance mechanism incorporates dynamic selection capabilities, allowing users to switch between different resistance types (inertia, wind, pressure) and adjust the intensity levels during exercise. The system dynamically adapts to user needs through selectable resistance sources and adjustable intensity settings, enhancing training customization
Solution Approach 2:
The multiple resistance components are arranged in a nested or integrated manner within the device structure. The fan wheel is positioned to interact with air flow, the pneumatic rod is integrated into the resistance mechanism, and the flywheel is connected to the rowing motion system, allowing compact integration of multiple resistance sources without excessive structural complexity
