Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rotating pedals or grips are used to drive the flywheel, then the exercise machine can provide smooth and consistent resistance through rotating inertia, but it cannot simulate climbing or rock climbing exercises that require reciprocating motion
Solution Approach 1:
The patent changes the motion parameter from rotational to reciprocating by replacing rotating pedals with reciprocating pedals that move back and forth in a linear path. This allows the exercise machine to simulate climbing and rock climbing motions while maintaining smooth resistance through the flywheel's rotating inertia, thus improving adaptability without sacrificing operation convenience
Solution Approach 2:
The patent introduces a dynamic transmission mechanism consisting of a driving wheel, driven wheel, and transmission belt that converts the reciprocating motion of the pedals into rotational motion of the flywheel. This dynamic system maintains the smooth resistance characteristics of rotational motion while enabling reciprocating exercise patterns, resolving the contradiction between motion type adaptability and operational smoothness
2Adaptability or versatility
If a linkage weight mechanism is used to provide reciprocating motion, then reciprocating exercise can be achieved, but adjusting exercise intensity requires loading or unloading weight blocks which is inconvenient
Solution Approach 1:
The patent replaces the mechanical weight loading system with a magnetic resistance system. The resistance wheel interacts with a magnetic field to provide adjustable resistance without physical weight blocks. Users can change exercise intensity by adjusting magnetic field strength through controls, eliminating the need to manually load or unload weights while maintaining reciprocating motion capability
Solution Approach 2:
The patent changes the resistance mechanism from gravitational (weight-based) to magnetic field-based. This allows continuous and convenient adjustment of resistance parameters through electronic controls rather than discrete weight block changes, improving ease of operation for intensity adjustment while preserving the reciprocating exercise function
3Power
If weight blocks are loaded or unloaded to change exercise intensity in a linkage weight mechanism, then resistance can be adjusted, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The patent substitutes the mechanical weight-based resistance system with an electromagnetic resistance system. The resistance wheel interacts with a magnetic field that can be adjusted electronically, allowing instant changes in exercise resistance without the time-consuming process of loading or unloading physical weight blocks
Solution Approach 2:
The patent introduces a dynamically adjustable magnetic resistance system where the resistance level can be changed in real-time during exercise through electronic controls. This eliminates the static, discrete resistance levels of weight blocks and allows continuous adjustment without interrupting the workout, thus reducing adjustment time while maintaining variable resistance capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables effective simulation of climbing and rock climbing exercises with easy intensity adjustment by converting reciprocating motion into rotary motion, providing suitable resistance for varied workout intensities without the need for weight loading.
Implementation Method 1
The resistance wheel is directly or indirectly driven by the main rotating wheel. The first reciprocating member reciprocally moves with the first reciprocating pivot portion as its axis. The second reciprocating member reciprocally moves with the second reciprocating pivot portion as its axis.
Implementation Method 2
allowing for easy adjustment of exercise intensity through friction, magnetic, or wind resistance
Implementation Method 3
One end of the first link is pivotally connected to the first pivot portion. Another end of the first link is directly or indirectly pivoted to the first face pivot portion. One end of the second link is pivotally connected to the second pivot portion. Another end of the second link is directly or indirectly pivoted to the second face pivot portion.
Implementation Method 4
Through the rotating inertia of the flywheel, the user can apply force to the exercise machine more smoothly and consistently

AI summary
A reciprocating transmission structure of an exercise machine, mounted to a frame of the exercise machine, includes a first reciprocating member, a second reciprocating member, a main rotating wheel, a first link, a second link, and a resistance wheel. The first reciprocating member reciprocally moves with a first reciprocating pivot portion as its axis. The second reciprocating member reciprocally moves with a second reciprocating pivot portion as its axis. The first link and the second link drive the main rotating wheel to rotate with a rotating shaft as its axis. The main rotating wheel drives the resistance wheel to rotate. After the first reciprocating member and the second reciprocating member move reciprocally, the resistance wheel can be driven to rotate by the cooperation of various components. The exercise machine is suitable for performing exercises related to reciprocating movement, and the operation is easier.
