Bar-End Device Assembly With Adjustable Mounting Shoes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bar-end device assemblies for bicycles are not easily adaptable to handlebars of different sizes and shapes, limiting their versatility and compatibility.
Innovation Solution
A bar-end device assembly featuring a base member with a mounting portion, shoes, and an adapter that can change its effective mounting dimension by using different shoes or adapters, allowing for secure attachment to various handlebar sizes and shapes, and incorporating a hydraulic unit for operating bicycle components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bar-end device assembly is designed with a fixed mounting dimension, then the structure is simple and easy to manufacture, but it cannot be adapted to handlebars of different sizes and shapes
Solution Approach 1:
The mounting mechanism transitions from a fixed structure to a dynamic, adjustable structure. The shoe component can be repositioned along the mounting portion, and the adapter can be selectively engaged to change the effective mounting dimension. This dynamic capability allows the same base member to adapt to different handlebar sizes without requiring multiple dedicated mounting structures.
Solution Approach 2:
The mounting mechanism is divided into separate functional components: a base member with mounting portion, removable shoes, and an adapter. This segmentation allows each component to be optimized independently and combined in different configurations to match various handlebar sizes, providing versatility while keeping individual components relatively simple.
2Adaptability or versatility
If multiple shoes with different configurations are provided to change the effective mounting dimension, then adaptability to different handlebars is improved, but the quantity of parts and device complexity increases
Solution Approach 1:
The base member with mounting portion is designed as a universal component that can work with different shoes and adapter configurations. This multi-functional design allows a single base member to serve multiple mounting scenarios, reducing the need for multiple dedicated mounting assemblies for different handlebar types.
Solution Approach 2:
The adapter is designed to be selectively engaged with the mounting portion, creating a nested configuration where the adapter fits within or onto the base member structure. This nesting approach allows the adapter to modify the effective mounting dimension without requiring completely separate mounting components, thereby reducing the overall quantity of parts needed.

AI summary
A bar-end device assembly is provided for a tube member of a bicycle. The bar-end device assembly has a base member that includes a mounting portion, a first shoe and a second shoe. The mounting portion is configured to be mounted within an interior of a free end provided on the tube member. The first shoe is configured to engage the interior of the tube member as the mounting portion is mounted to the tube member with the first mounting shoe disposed on the mounting portion. The second shoe is configured to engage the interior of the tube member as the mounting portion is mounted to the tube member with the second mounting shoe disposed on the mounting portion. The first and second shoes have different configurations and are used one at a time to change an effective mounting dimension of the base member.
