Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a machine provides natural motion and body leverage for muscle isolation, then exercise effectiveness is improved, but resistance adjustment becomes complicated
Solution Approach 1:
The patent changes the physical parameter of the rope by altering its curvature through a tension member. By adjusting the curvature of the rope, the resistance force is modified without changing the mechanical structure of the machine, thus simplifying resistance adjustment while maintaining natural motion and body leverage.
Solution Approach 2:
The tension member is made movable along the rope to dynamically adjust the curvature and resistance. This dynamic adjustment mechanism allows users to easily vary resistance levels during exercise without complicated fixed settings, resolving the contradiction between ease of operation and device complexity.
2Force
If the tension member increases curvature of the material, then resistive force increases, but the complexity of adjusting resistance increases
Solution Approach 1:
The tension member is designed to be movable along the rope, allowing dynamic adjustment of curvature and resistive force. Users can easily move the tension member to different positions to achieve desired resistance levels, making the adjustment process simple while maintaining effective force variation.
Solution Approach 2:
The system adjusts resistance by changing the curvature parameter of the rope through the tension member's position. This parameter-based adjustment allows for easy modification of resistive force without requiring complex mechanical reconfiguration, thus improving ease of operation while maintaining effective force control.
