Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise machines lack versatility in exercise options, require inconvenient weight adjustments, and fail to provide both the tactile feedback of traditional weights and the dynamic control of electronic resistance, leading to limited training effectiveness and user engagement.
Innovation Solution
A hybrid resistance generation system combining a weight stack with a plurality of weights and an electromechanical resistance module, where both sources are connected in series, allowing for continuous adjustment and precise control of resistance through a sensor system and electromechanical module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a weight stack with physical weights is used, then haptic feedback and neuromuscular coordination are improved, but weight adjustment requires interrupting the exercise and moving away from the training position
Solution Approach 1:
The resistance system is segmented into two independent parts: a weight stack providing base resistance and an electromechanical module providing adjustable resistance. This segmentation allows the electromechanical part to be adjusted independently during exercise without moving physical weights.
Solution Approach 2:
The patent replaces the mechanical weight adjustment mechanism with an electromechanical resistance module that can be adjusted via motor control. This substitution eliminates the need to physically move weight plates and interrupts exercise flow.
2Adaptability or versatility
If an electromechanical resistance system is used, then dynamic resistance control is improved, but haptic feedback and user motivation are reduced
Solution Approach 1:
The patent merges two resistance systems into a hybrid configuration where the weight stack and electromechanical module work together. This combination preserves the haptic feedback of physical weights while adding the dynamic control capabilities of electronic resistance.
Solution Approach 2:
The resistance system uses a composite approach combining mechanical weights and electromechanical components. This composite structure provides both the tactile experience of traditional weights and the programmable flexibility of electronic control.
3Object-generated harmful factors
If only physical weights are used, then haptic feedback is maintained, but the range of exercises and training options is limited
Solution Approach 1:
The hybrid resistance system provides multi-functionality by enabling various exercise modes: traditional weight-based exercises, electromechanical-assisted exercises, and combined hybrid exercises. This universality expands the range of trainable movements while preserving haptic feedback.

AI summary
The application relates to a hybrid resistance generation system for an exercise machine, comprising a weight stack providing a first resistance source and an electromechanical resistance module providing a second resistance source. The two resistance sources are connected in series via a weight sword, so that a combined resulting resistance acts on a first cable that is operably connected to a user interface. The electromechanical resistance module includes an electric motor with a winch for winding and unwinding a second cable, which is detachably connected to the weight sword via a tool-free adapter.
