Bicycle Stand Mounting Geometry for Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bicycle frames are often manufactured with rear wheel stand attachments that are aesthetically unappealing when not needed, as they can be perceived as visually disturbing and require unnecessary equipment for customers who prefer a center stand or do not need a bike stand at all.
Innovation Solution
A bicycle stand arrangement featuring a fastening geometry with two stud-type stubs housed in cooperating pockets, providing a ring-shaped contact line for secure mounting without play, while maintaining a small footprint for an unobtrusive design. This geometry can be integrated into the bicycle frame's chainstay or dropout, allowing for adjustable placement and avoiding collisions with other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mounting bases with large contact surfaces are used, then secure attachment is achieved, but the mounting base becomes visually obtrusive when the stand is not installed
Solution Approach 1:
The mounting base is segmented into two functional parts: a large-area fastening geometry (stud-type stubs in pockets) for secure attachment, and a minimal visible footprint on the frame. This segmentation allows the fastening elements to be hidden while maintaining attachment security.
Solution Approach 2:
The visible mounting base plate is extracted/removed from the design. Only the essential fastening elements (studs and pockets) remain, which can be positioned to minimize visual impact while providing sufficient contact area for secure attachment.
2Shape
If the fastening geometry is made compact with small footprint, then visual appearance is improved, but attachment security may be compromised
Solution Approach 1:
The contact interface uses a ring-shaped contact line (circular geometry) around each stud-pocket interface, which provides optimal contact distribution on a small area. The curved geometry maximizes contact efficiency within minimal space.
Solution Approach 2:
The fastening system uses stud-type stubs with specific dimensional parameters (diameter, length, pocket depth) that are optimized to provide maximum attachment security within a minimal footprint. The parameters are tuned to achieve reliable attachment without requiring large contact surfaces.
3Adaptability or versatility
If mounting bases are pre-installed on all frames, then all customers receive functional equipment, but customers who don't need stands receive visually disturbing equipment
Solution Approach 1:
The fastening geometry is designed to be dynamically configurable - it can be positioned at different locations on the frame (chainstay, dropout, or other locations) depending on customer needs and component layout requirements, allowing optimization for both aesthetics and function.
Solution Approach 2:
The fastening geometry serves multiple functions: it provides secure attachment, maintains aesthetic appearance when stand is removed, and can be positioned at various locations to accommodate different customer preferences and component configurations.

AI summary
In a bicycle stand arrangement comprising a mounting base designed as an integral part of a bicycle frame (9) and arranged on the bicycle frame (9) in the area of the rear wheel (1), and a bicycle stand (6) having a stand head (7) detachably fixed to the mounting base by means of fastening screws (10), and a support (8) pivotably held on the stand head (7) which is movable between two end positions designated as the stationary position and the riding position, wherein the mounting base and the stand head (7) form two complementary components of a mounting geometry that secures the bicycle stand (6) to the bicycle frame (9) in a rotationally secure manner, the invention proposes that the mounting geometry has, on the one hand, two pin-shaped prongs (11), and, on the other hand, two pockets (15) in which the prongs (11) are received.
