Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional vertical oscillation devices are used, then vertical oscillation is generated, but U-shaped oscillation is actually generated instead of pure vertical movement, causing instability and safety issues
Solution Approach 1:
The transmission mechanism is divided into multiple independent components: transmission shaft, 8-shaped bearing blocks, horizontal transmission rods, and triangular bearing blocks. Each component performs a specific function in the movement conversion process, allowing precise control over the oscillation path to achieve pure vertical movement only.
Solution Approach 2:
The 8-shaped bearing blocks and triangular bearing blocks act as intermediary elements between the rotating transmission shaft and the tread board. These intermediaries convert the circular motion of the shaft into horizontal linear movement, which is then converted into vertical oscillation, eliminating direct lateral movement of the tread board.
2Ease of operation
If U-shaped oscillation is generated, then vertical movement is achieved, but lateral movements occur causing equipment instability
Solution Approach 1:
The 8-shaped bearing blocks have asymmetric geometry with one end eccentric and the other end horizontal. This asymmetric design ensures that the bearing blocks convert rotational motion into purely horizontal linear motion at the horizontal action end, which then translates to vertical oscillation at the vertical action end, preventing lateral movement.
Solution Approach 2:
The transmission mechanism systematically changes the dimension of motion at each stage: the transmission shaft provides rotational motion (angular dimension), the 8-shaped bearing blocks convert this to horizontal linear motion (horizontal dimension), and the triangular bearing blocks convert horizontal motion to vertical oscillation (vertical dimension), eliminating lateral dimensional movement.
3Reliability
If complex transmission mechanisms are used to achieve pure vertical oscillation, then stability is improved, but device complexity increases
Solution Approach 1:
The transmission mechanism is designed as a universal system that can be applied to different types of vertical oscillation equipment (treadmills, steppers, bed-style devices). The same basic components (transmission shaft, bearing blocks, transmission rods) can be configured for different applications, reducing overall system complexity despite the sophisticated motion conversion.

AI summary
A vertical oscillation auxiliary platform, wherein a drive mechanism drives an upper cover tread board to make vertical up-and-down movements with a transmission mechanism; when the drive mechanism drives a transmission shaft rotate, the transmission shaft drives lower parts of 8-shaped bearing blocks to rotate eccentrically, and upper parts thereof move horizontally; the 8-shaped bearing blocks drive one end of triangular bearing blocks to move horizontally with horizontal transmission rods, and the triangular bearing blocks, without moving a third end, convert horizontal movements at one end to be vertical movements at another end, and drive finally the upper cover tread board to generate stable vertical oscillation, so that singularity and stability of vertical movements of the upper cover tread board can be promised, and more stable and comfortable feeling and passive exercise effects can be gained, without deteriorating the exercise effects and exercise comfort due to additional disorganized lateral movements.
