Bicycle Accessory Mount with Curved Constriction Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for attaching accessories, such as bicycle locks, to bicycles face challenges in providing a flexible, reliable, and space-efficient attachment method that does not require additional protruding elements, while maintaining the accessory's integrity and aesthetics.
Innovation Solution
A holder with a continuous channel design that allows accessories to be inserted through one end and limited by a constriction at the other, featuring guide elements and a latching mechanism for secure positioning, and can be adapted for different fastening types and orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a continuous channel with constriction section is used to hold the accessory, then the accessory can be securely attached without protruding elements, but the channel must be designed with specific geometric features to prevent removal
Solution Approach 1:
The channel features a curved constriction section that transitions from a wider first section to a narrower second section. This curved geometric design allows the accessory to be easily inserted while preventing removal, resolving the contradiction between ease of operation and device complexity by using smooth curvature rather than sharp angles or complex mechanisms.
2Manufacturing precision
If guide elements are added to the channel, then the accessory positioning precision is improved, but the device complexity increases
Solution Approach 1:
The guide elements are integrated directly into the channel wall structure rather than being separate components. This merging approach provides precise positioning guidance for the accessory while minimizing device complexity by eliminating the need for additional detachable parts.
3Ease of operation
If the channel is completely open at both ends, then the accessory can be freely inserted, but the accessory cannot be retained securely
Solution Approach 1:
The constriction section with its curved geometry creates a retention mechanism where the narrower second section prevents the accessory from being removed while the wider first section allows easy insertion. This curved design resolves the contradiction between insertion ease and retention security.
Solution Approach 2:
The channel is segmented into distinct functional sections: a wider first section for insertion, a curved constriction section for retention, and a narrower second section for preventing removal. This segmentation allows each section to perform its specific function optimally.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible and reliable attachment of accessories like bicycle locks without protruding elements, ensuring secure holding and easy release, while maintaining the accessory's functionality and appearance.
Implementation Method 1
the locking element, in a locking position, springs back into the receiving area of the receiving section of the base body in order to lock the retaining section of the accessory inserted into the receiving area
Implementation Method 2
the fastening element has a fastening device for attaching the bracket to the two-wheeler

AI summary
A bracket (11) for attaching an accessory (29) to a two-wheeled vehicle comprises a base section (15) for attaching the bracket (11) to the two-wheeled vehicle and a receiving section (17) for receiving a pin-shaped retaining section of the accessory. The receiving section (17) has a continuous channel (19) extending along a channel axis (K), which has at a first end (21) an inlet section (25) for inserting the retaining section (27) of the accessory (29) into the continuous channel (19) and at a second end (23) opposite the first end (21) a constricting section (31) whose cross-section is narrowed compared to the inlet section (25) in order to limit the insertion of the retaining section (27) of the accessory (29) into the continuous channel (19).
