Bicycle Stem Accessory Holder Using Segmented Clamping Shell
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for attaching accessories to bicycles, particularly e-bikes, face challenges due to limited space on the handlebars and the obstruction caused by handlebar clamp clamping shells, making central attachment complicated.
Innovation Solution
A system utilizing a clamping shell formed as part of the handlebar clamp, with a holder that can be fastened to a web within the clamping shell, allowing for simple and stable attachment of accessories like lights directly to the bicycle stem.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handlebar clamp is used to attach accessories, then the accessory can be mounted on the handlebars, but the clamping shells obstruct central attachment and make the process complicated
Solution Approach 1:
The clamping shell is divided into two halves that are connected via webs, creating openings that allow the holder to be attached. This segmentation enables the holder to pass through and be secured to the stem without obstructing the attachment process.
Solution Approach 2:
A holder is introduced as an intermediary component between the accessory and the stem. The holder comprises engagement elements that connect to the webs of the clamping shell, simplifying the attachment process and enabling central mounting without direct interference from the clamping shells.
2Reliability
If the accessory is attached centrally to the stem, then the accessory is in direct mechanical contact with the sturdy stem, but the clamping shells stand in the way of central attachment
Solution Approach 1:
The clamping shell is segmented into two halves connected by webs, creating openings that allow the holder to be positioned centrally on the stem. This segmentation removes the obstruction caused by solid clamping shells while maintaining the structural integrity needed for reliable mechanical contact.
Solution Approach 2:
The obstruction caused by the clamping shells is removed by extracting material to form openings. These openings allow the holder to be attached centrally to the stem, enabling direct mechanical contact between the accessory and the sturdy stem while maintaining ease of attachment.
3Ease of operation
If the holder is suspended on the web, then the attachment is simple and stable, but the holder must be precisely positioned
Solution Approach 1:
The holder is designed with engagement elements that automatically engage with the webs of the clamping shell when the holder is positioned on the stem. This self-service mechanism allows the holder to be attached simply by suspending it on the web, with the engagement elements securing the holder in the correct position without requiring additional adjustment.
