Bicycle Stem Assembly with Forward Support for Display Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bicycles with display devices face challenges in securing enough space on the handlebar, leading to uncomfortable display positioning and reduced visibility for riders, especially in electric assist bicycles where multiple devices need to be mounted.
Innovation Solution
A handle stem assembly with a forward-extending support that includes attachments for the display and other components, allowing for improved placement and visibility of the display, while also simplifying the layout of devices around the handlebar through cable guides and supplementary attachments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is attached to the upper side of the stem, then more devices can be arranged around the handlebar, but the display is positioned high which reduces visibility and comfort for the rider
Solution Approach 1:
The patent transitions from vertical attachment (upper side of stem) to horizontal attachment (front side of stem extending forward). This dimensional change allows the display to be positioned lower and forward, improving visibility while maintaining device arrangement capacity through the extended support structure
2Adaptability or versatility
If multiple devices are attached to the handlebar, then functionality is enhanced, but there is not enough space and the layout becomes complicated
Solution Approach 1:
The patent divides the mounting structure into separate functional components: the handle stem, the extending support, and multiple attachment points. This segmentation allows independent positioning of the display and other devices, simplifying the overall layout while accommodating multiple devices
Solution Approach 2:
The support structure serves multiple functions: it extends forward to position the display at an optimal viewing angle, provides attachment points for multiple devices, and integrates with the handle stem. This multi-functionality reduces the need for separate mounting structures, simplifying the overall system

AI summary
A bicycle includes a handlebar, a handle stem on which the handlebar is disposed, a clamp that is attached to the handle stem to fix the handlebar on the handle stem, and a support extending forward and including a first attachment. The first attachment is located farther forward than the handlebar. A display is attached to the first attachment so that the display is placed at an appropriate height to improve visibility of the display.
