Engineering Contradiction Analysis
1Adaptability or versatility
If traditional weight-based exercise machines are used, then the structure is simple and easy to operate, but they fail to accommodate the athlete's full force potential during eccentric phase and lack flexibility in resistance adjustment
Solution Approach 1:
The patent applies dynamics by making the resistance force adjustable and variable throughout the range of motion. The exercise machine allows the resistance to change dynamically based on the athlete's position and force output, rather than maintaining a fixed weight. This enables the machine to accommodate the athlete's full force potential during both concentric and eccentric phases by adjusting the resistance profile to match the athlete's capabilities at each point in the movement.
Solution Approach 2:
The patent implements parameter changes by allowing continuous adjustment of resistance magnitude and direction. The system can modify the resistance force parameter throughout the exercise range, transitioning from fixed weight to variable resistance that adapts to the athlete's force production capabilities. This includes adjusting resistance during eccentric and concentric phases to fully utilize the athlete's force potential.
2Adaptability or versatility
If fixed weight is used in traditional exercise machines, then the device complexity is low, but the resistance cannot be adjusted during a set or repetition
Solution Approach 1:
The system implements dynamic resistance adjustment during exercise execution. The resistance force is not fixed but can be modified in real-time based on the athlete's performance, position, and force output. This allows the machine to adapt resistance levels during sets and repetitions without requiring complex manual intervention, achieving continuous variability that matches athletic performance characteristics.
Solution Approach 2:
The exercise machine incorporates self-service capabilities by automatically adjusting resistance based on the athlete's force output and position. The system monitors the athlete's performance and autonomously modifies the resistance profile, eliminating the need for constant manual adjustment. This self-adjusting mechanism provides continuous resistance optimization while maintaining operational simplicity.
3Adaptability or versatility
If weight-based exercise is used, then the loading is fixed, but it does not match the force generating capability of the athlete during eccentric direction
Solution Approach 1:
The patent applies parameter changes by modifying the resistance force parameter to match the athlete's force-generating capability across different phases of movement. The system adjusts resistance magnitude and direction based on the athlete's position and force output, particularly optimizing for the eccentric phase where athletes can generate higher forces. This creates a resistance profile that accurately reflects and matches athletic capability throughout the full range of motion.
Solution Approach 2:
The exercise machine incorporates feedback mechanisms that monitor the athlete's force output and position in real-time. This feedback information is used to dynamically adjust the resistance force, ensuring it matches the athlete's capability at each point in the movement. The system continuously receives feedback from sensors and modifies resistance accordingly, creating an adaptive force profile that optimizes training effectiveness.
