Aquatic Bicycle Height Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aquatic devices do not allow users to adjust their distance from the water surface while maintaining a substantially vertical back position, limiting user flexibility and comfort during water activities.
Innovation Solution
The aquatic device features a bicycle frame that can be adjusted in height relative to the floating boards through movement means, transmission means, and enabling/disabling mechanisms, allowing users to move from being completely below to completely above the water surface while maintaining a vertical back position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bicycle is fixed at a constant height relative to the floats, then the device structure is simple and stable, but the user cannot adjust their distance from the water surface
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed bicycle structure into a movable one. The bicycle frame is equipped with a telescopic rod that can extend and retract, allowing the bicycle to move vertically relative to the floats. This dynamic structure enables users to adjust their position from completely above the water surface to partially submerged, while maintaining structural stability through the telescopic mechanism's locking and unlocking systems.
Solution Approach 2:
The telescopic rod employs the nested doll principle by having one rod inserted within another rod. The inner rod can slide within the outer rod, allowing compact storage when retracted and extended configuration when needed. This nesting mechanism achieves height adjustment functionality while minimizing the space required when the adjustment feature is not in use.
2Adaptability or versatility
If the bicycle is positioned above the water surface, then the user does not get wet, but the user cannot experience water-based activities while maintaining comfort
Solution Approach 1:
The dynamic height adjustment mechanism allows users to transition between dry and wet positions according to their activity needs. When the telescopic rod is retracted, the bicycle is positioned above the water for dry comfort. When extended, the bicycle lowers to allow users to engage in water-based activities such as swimming or wading, while the vertical stroke mechanism ensures smooth transitions between positions.
Solution Approach 2:
The patent changes the vertical position parameter of the bicycle relative to the water surface. By adjusting the extension length of the telescopic rod, the system varies the height parameter, enabling users to select between being completely above water (dry position) and partially below water (wet position), thus adapting to different comfort and activity requirements.
3Adaptability or versatility
If the bicycle is lowered to allow users to be partially below water, then water activities are enabled, but the user cannot maintain a vertical back position
Solution Approach 1:
The vertical stroke mechanism maintains the bicycle in a vertically oriented position throughout its movement range. The telescopic rod moves strictly in the vertical direction, ensuring that the bicycle frame remains perpendicular to the water surface. This dynamic vertical positioning allows users to maintain a natural vertical back posture whether partially submerged or completely above water, providing posture stability across all operating positions.
