Solution Overview

Problem

Conventional bicycle water bottle attachments are limited by dimension and aerodynamics, requiring specific brackets for different stem dimensions, which restricts versatility and stability.

Innovation Solution

A handlebar assembly with an integrally-formed bottle coupling structure that is directly connected to and dissociable from the handlebar, allowing for adjustable attachment to various stem dimensions and improved aerodynamics through a stem-clamping mechanism and engaging grooves/protrusions system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a water bottle is attached onto the upper side of the handlebar by a bracket or straps, then the bottle can be supported by the handlebar, but the dimension of the water bottle permitted to be stably supported is limited and the position is adverse to aerodynamics

Engineering Contradiction:

Improvestability of bottle supportVSAvoidaerodynamic performance

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Instead of attaching the bottle to the upper side of the handlebar as in conventional designs, this patent inverts the attachment position to the lower side of the handlebar. The coupling structure engages with the handlebar from below, positioning the bottle in a location that improves aerodynamic performance while maintaining stable support through the specialized coupling mechanism.

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of operation

If a water bottle is disposed below the handlebar with a bracket fixed to the stem, then the bottle can be attached, but different brackets are needed for stems of different dimensions

Engineering Contradiction:

Improveattachment capabilityVSAvoidcompatibility with different stem dimensions

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The coupling structure is designed with universal adaptability to work with handlebars of various dimensions and stem configurations. The coupling mechanism incorporates adjustable components and multiple engagement options that allow it to accommodate different stem sizes without requiring separate brackets for each configuration, making the system multi-functional across various bicycle types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The coupling structure utilizes adjustable parameters such as movable clamping elements and flexible mounting positions that can be modified to match different stem dimensions. By changing the physical parameters of the coupling mechanism (such as clamp width, bolt position, or engagement depth), the same bracket can be adapted to fit various handlebar and stem sizes.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If conventional brackets or straps are used to attach the water bottle, then the bottle can be supported, but the assembly requires multiple components and is not suitable for all stem dimensions

Engineering Contradiction:

Improvesupport capabilityVSAvoidnumber of components required

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the functions of multiple separate components (bracket, straps, mounting mechanism) into a single integrated coupling structure. This unified design combines the support, attachment, and adjustment functions into one cohesive assembly that directly couples the bottle to the handlebar, eliminating the need for multiple separate parts while maintaining reliable support capability.

Inventive Principle:

Principle #5Merging (Combining)
