Bicycle Water Bottle Holder Angular Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water bottle holders for bicycles are not angularly adjustable, leading to discomfort for users when accessing the bottles.
Innovation Solution
A water bottle holder assembly featuring a board with axial slots, pivotable clamp units, and a support unit with a threaded connection, allowing angular adjustment of the bottle holders relative to the seat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the water bottle holder assembly uses a fixed connection structure, then the installation is simple and stable, but the bottle holders cannot be angularly adjusted making user access uncomfortable
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed connection structure into a dynamic, adjustable one. The clamp units can pivot between clamped and unclamped states, and the support unit can rotate at multiple angles (0°, 45°, 90°) relative to the board, enabling the bottle holder to adapt to different positions and user access needs while maintaining installation simplicity
2Adaptability or versatility
If the water bottle holder assembly uses adjustable clamp units with pins and bolts, then the angular adjustment is enabled, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the adjustable mechanism into independent clamp units, each with its own pin and bolt components. This modular approach allows angular adjustment functionality to be distributed across multiple simple units rather than requiring a single complex adjustment mechanism, thereby reducing overall device complexity while maintaining adaptability
3Reliability
If the support unit uses a threaded connection with a second bolt, then the angular positioning is secure, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies the intermediary principle by introducing a threaded connection as a mediator between the support unit and the board. This threaded interface acts as a precise positioning element that translates rotational movement into secure angular positioning, while the threading mechanism itself accommodates minor manufacturing variations through its inherent tolerance characteristics

AI summary
A water bottle holder assembly includes a board and a link extending from the board. The board includes two slots defined axially therethrough. The link includes a connection end which has a first toothed face. Two clamp units are connected to the board, and each clamp unit includes two blocks. Each of the blocks includes a passage through which a first bolt extends, and the first bolt extends through the slot and is connected with a nut. The two blocks are pivotably connected to each other at one end so as to clamp the seat rail between the two blocks. A support unit includes a plate with an extension extending laterally from the plate. A water bottle holder is connected to the plate. The extension includes an engaging part which has a second toothed face adjustably engaged with the first toothed face so that the holder is angularly adjustable.
