Bicycle Electronic Device Holder with Anti-Rotation Support Brace
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle electronic device holders can rotate relative to the handlebar, causing the electronic device to be out of the rider's view and potentially damaged during use.
Innovation Solution
A bicycle electronic device holder with a support brace extending inwardly from the collar to engage the underside of the handlebar stem, preventing rotation and featuring a mount with elastic members for secure device attachment, a hinged collar for easy installation, and a split ring with a support member to stabilize the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple collar mount is used for the electronic device holder, then the device holder is lightweight and easy to install, but the collar can rotate relative to the handlebar causing the device to be out of view or damaged
Solution Approach 1:
The collar is divided into two separate components: the collar itself and the support brace. The collar provides easy mounting around the handlebar, while the separate support brace extends inward to engage the underside of the handlebar stem, preventing rotation. This segmentation allows each component to perform its specific function optimally without compromising the other.
Solution Approach 2:
The support brace acts as an intermediary element between the collar and the handlebar stem. It transfers the rotational constraint from the collar to the stem by engaging the underside of the stem, thereby preventing collar rotation without requiring direct attachment between the collar and stem.
2Reliability
If a support brace is added to prevent collar rotation, then the device position stability is improved, but the device holder becomes more complex
Solution Approach 1:
The support brace is integrated with the collar assembly such that it forms a unified mounting structure. The brace extends from the collar and combines with it to create a single functional unit that provides both easy installation and rotation prevention, reducing the perceived complexity despite adding rotational constraint capability.
Solution Approach 2:
The support brace serves multiple functions: it prevents collar rotation, provides structural support, and engages with the handlebar stem. By combining multiple functions into a single component, the overall system complexity is minimized while achieving reliable device position stability.

AI summary
A electronic device holder including a mount for securing an electronic device thereto, a collar for mounting about a bar, and a shaft between the collar and the mount. A support brace preferably associated with the collar and is configured for engagement with the underside of a bar stem to prevent rotation of the collar about the bar.
