Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise machines lack the ability to provide a versatile range of exercises without limitations, require inconvenient weight adjustments, and fail to offer realistic haptic feedback, especially when combining physical weights with electromechanical resistance systems.
Innovation Solution
A hybrid resistance generation system integrating a weight stack with a plurality of weights and an electromechanical resistance module, connected in series, providing both tactile feedback and dynamic resistance adjustment, allowing for non-linear force distribution and seamless transitions between resistance sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If physical weights are used to provide resistance, then haptic feedback and user motivation are improved, but weight adjustment convenience deteriorates
Solution Approach 1:
The patent combines physical weight stacks with an electromechanical resistance module in a hybrid system. The physical weights provide haptic feedback and motivation, while the electromechanical module enables easy, interruption-free weight adjustments through motorized control, resolving the contradiction between tactile quality and adjustment convenience.
Solution Approach 2:
The electromechanical resistance module acts as an intermediary that supplements the physical weight system. It provides motorized resistance adjustment capability while working together with the physical weights, allowing users to benefit from both haptic feedback and convenient electronic control without replacing either component.
2Ease of operation
If electromechanical resistance systems are used to replace physical weights, then weight adjustment convenience is improved, but haptic feedback and user motivation deteriorate
Solution Approach 1:
Instead of replacing physical weights with electromechanical systems, the patent merges both approaches. The physical weight stack remains the primary resistance source to maintain haptic feedback, while the electromechanical module adds motorized adjustment capability, achieving both convenience and tactile quality simultaneously.
3Device complexity
If a single resistance source is used, then device complexity is reduced, but exercise versatility and customization options deteriorate
Solution Approach 1:
The patent merges two resistance sources - physical weight stacks and electromechanical modules - to create a hybrid system. This combination provides exercise versatility and customization options while maintaining manageable complexity through integrated design, allowing users to leverage the strengths of both resistance types.
Solution Approach 2:
The hybrid resistance system provides multi-functionality by enabling both physical weight-based exercises and electromechanical resistance exercises on the same device. This universal design allows a single machine to support diverse exercise types and customization options that would otherwise require separate equipment.
