Exercise Cycle Cam Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise cycles have complex and time-consuming adjustment mechanisms for seat and handle bar positions, which can hinder user customization and comfort during workouts.
Innovation Solution
An exercise cycle with a guide frame and sliding frame adjustment mechanism, featuring pivotally disposed cams that allow for easy adjustment of seat and handle bar positions, along with a pivot assembly for rotating the console, enabling users to tailor their workout experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional adjustment mechanisms are used for seat and handle bar positions, then the exercise cycle can accommodate users of different sizes, but the mechanisms are complicated and time-consuming to manipulate
Solution Approach 1:
The patent employs a dynamic cam mechanism that transitions between locked and unlocked states through rotation. The cam profile is designed such that rotating the cam in a specific direction engages locking surfaces to fix the seat or handle bar position, while rotating in the opposite direction disengages the locking surfaces, allowing smooth adjustment. This dynamic state change enables easy operation while maintaining stability in the adjusted position.
Solution Approach 2:
The adjustment mechanism utilizes changes in the geometric parameters of the cam profile to control the locking and unlocking states. By varying the radial distance, angular position, and slope of the cam surface, the mechanism achieves reliable engagement and disengagement. The cam's rotational angle serves as the control parameter that transforms linear adjustment motion into locked/unlocked states, simplifying user interaction.
2Ease of operation
If the console is fixed in position, then the structure is simple, but the user cannot view exercise instructions comfortably during various workout positions
Solution Approach 1:
The console is mounted on a pivot assembly that allows it to rotate between a first position (facing the seat for cycling instructions) and a second position (facing away from the seat for standing or alternative exercise positions). This dynamic repositioning capability enables the console to adapt to different workout scenarios without requiring multiple fixed consoles, maintaining structural simplicity while improving usability.
Solution Approach 2:
The pivotable console serves multiple functions by being repositionable for different exercise modes. A single console structure can display instructions for cycling, standing exercises, or other activities by simply rotating to the appropriate orientation. This multi-functionality eliminates the need for separate consoles for different exercise types, reducing overall device complexity while enhancing versatility.

AI summary
Embodiments relate to exercise systems, and more particularly to adjustable exercise cycles. In accordance with at least some aspects, a stationary exercise cycle includes an incline mechanism that adjusts an incline of an upright support structure. The incline mechanism is aligned with a portion of an upright support structure on which a handle bar assembly is mounted. In some cases, the exercise cycle includes a console that can be rotated for viewing when not riding on the exercise cycle. The exercise cycle can also include an adjustment mechanism for adjusting the position of a seat or the handle bar assembly. The adjustment mechanism can include a cam-based locking mechanism for selectively securing the seat or handle bar assembly in place.
