Bicycle Hydration System Frame Hose Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle hydration systems, such as water bottles and bladders, often obstruct the rider's movement and do not efficiently manage hose routing, limiting hydration accessibility and aerodynamics during cycling.
Innovation Solution
A hydration system integrated into the bicycle frame with a substantially rigid reservoir, collapsible bladder, and hose routing through strategically designed openings in the frame and fork assembly, allowing for rotation and adjustable seatpost without direct coupling to the seatpost, enhancing fluid capacity and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hydration system is integrated into the bicycle frame with rigid reservoir and hose routing through frame openings, then hydration accessibility and aerodynamics are improved, but device complexity and routing difficulty increase
Solution Approach 1:
The frame is divided into multiple sections with dedicated openings for hose routing at strategic locations (front opening near headset bearing, rear opening near seat tube). This segmentation allows the hose to be routed through discrete, pre-defined paths rather than requiring complex custom routing, thereby reducing overall routing complexity while maintaining accessibility.
Solution Approach 2:
The patent uses the frame structure itself as an intermediary element to guide and constrain the hose routing. The frame openings and internal cavity act as mediators that naturally direct the hose from the reservoir to the drinking location, eliminating the need for additional routing components or complex assembly procedures.
2Shape
If the reservoir is positioned behind the seat tube with hose routing through the frame, then aerodynamics are improved, but ease of manufacture and assembly decrease
Solution Approach 1:
The frame is designed with pre-positioned openings and internal cavities during the manufacturing process. The rear opening is pre-formed at the appropriate location behind the seat tube, and the internal routing path is pre-defined. This preliminary preparation eliminates the need for complex post-assembly routing operations, making assembly easier despite the aerodynamic positioning requirements.
Solution Approach 2:
The frame structure incorporates localized features (openings, cavities, and routing paths) at specific locations optimized for aerodynamics. The rear opening is positioned locally behind the seat tube, and the internal cavity is shaped to guide the hose along the most aerodynamic path, while these localized modifications do not significantly complicate overall manufacturing.
3Adaptability or versatility
If the hose passes through the main frame above the bottom bracket, then routing flexibility and aerodynamics are improved, but reliability and sealing requirements increase
Solution Approach 1:
The frame's internal cavity and pre-formed openings act as intermediary structures that guide the hose through a controlled path. The hose is routed through a dedicated internal cavity that provides a stable, sealed passage from the rear opening to the front opening, eliminating the need for complex external sealing arrangements while maintaining routing flexibility.
Solution Approach 2:
The patent employs a flexible hose that can be routed through the frame opening and secured within the internal cavity. The flexible nature of the hose allows it to accommodate minor positioning variations and maintain reliable sealing at the connection points while still providing the necessary routing flexibility for aerodynamic positioning.
4Adaptability or versatility
If the fork assembly includes a wide fork opening to allow fork rotation, then adaptability and maneuverability are improved, but device complexity and hose routing difficulty increase
Solution Approach 1:
The fork assembly is segmented with a dedicated wide opening specifically for hose routing, separate from the fork rotation mechanism. This segmentation allows the hose to pass through a broad opening that accommodates fork rotation without requiring the hose itself to be overly complex or require additional routing components.
Solution Approach 2:
The wide fork opening is designed to dynamically accommodate the fork's rotational movement. The opening maintains its broad dimensions throughout the rotation range, allowing the hose to remain properly positioned and routed while the fork rotates, thereby simplifying the routing design despite the dynamic movement requirement.

AI summary
A bicycle comprises a frame assembly and a hydration system. The frame assembly includes a main frame and a fork assembly pivotally coupled to the main frame. The hydration system includes a reservoir supported by the frame assembly, a collapsible bladder positioned in the reservoir, and a hose coupled to the bladder and extending through a reservoir opening. The hose enters the main frame through a frame opening and passes through an inside of the main frame above a bottom bracket. The hose exits the main frame through a front opening and enters the fork assembly through a fork opening facing toward the front opening. The fork assembly can also include a nose piece in front of the headset bearing, wherein the hose passes between headset bearing and the nose piece. The fork assembly can also include a handlebar and a riser supporting the handlebar, wherein the hose passes through the riser.
