Elastic Clamping Device for Bicycle Frame Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bicyclists face challenges in quickly and securely attaching lightweight items like jackets or tools to bicycle frames without additional luggage racks, often relying on backpacks due to the lack of suitable attachment options.
Innovation Solution
An elastic clamping device with a mounting element and connecting screw is used to wrap around the bicycle frame, providing a secure attachment point by tensioning the device around the frame and using a spacer section to maintain the holding head at a sufficient distance for reliable engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connecting screw is used to attach the clamping device to the bicycle frame, then the mounting element can be connected to the holding head, but the holding head may be too close to the frame part for reliable engagement
Solution Approach 1:
A spacer element is introduced as an intermediary component between the holding head and the threaded shaft of the connecting screw. This spacer ensures that the holding head maintains a sufficient distance from the bicycle frame, enabling reliable engagement of the mounting element with the holding head while preventing the holding head from being too close to the frame surface.
2Reliability
If the clamping device is made elastic and wrap-around capable, then it can securely clamp objects to the frame, but the mounting element may jump off the holding head under shock loads
Solution Approach 1:
The clamping device utilizes elastic material properties to create a dynamic, adjustable clamping force that adapts to the shape of the bicycle frame and the object being secured. The elasticity allows the device to maintain secure clamping while accommodating movements and vibrations during cycling.
Solution Approach 2:
The spacer element serves as a mechanical intermediary that provides structural stability to the connection assembly. By positioning the holding head at an optimal distance from the frame, the spacer prevents the mounting element from disengaging under shock loads while still allowing the elastic clamping device to function effectively.
3Adaptability or versatility
If additional luggage racks are added to the bicycle frame, then more attachment options are available, but the device complexity and weight increase
Solution Approach 1:
The connecting screw assembly with holding head and spacer serves multiple functions: it provides a secure mounting point for the clamping device, maintains proper spacing for reliable engagement, and can be positioned at various locations on the bicycle frame. This multi-functional component eliminates the need for dedicated luggage racks while providing versatile attachment capabilities.
Solution Approach 2:
The invention changes the approach from adding permanent structural modifications (luggage racks) to using adjustable, removable fastening components. The connecting screws can be positioned at different locations and the clamping device can be easily attached and removed, providing versatility without permanently increasing frame complexity.

AI summary
The invention relates to a fastening device that can be mounted on a bicycle, consisting essentially of an elastic, elongated clamping element (17) which is provided at least at one of its two end regions (19) with a mounting element (20) for positive-locking connection to a retaining head (21) of a connecting screw (16). The connecting screw (16) is screwed onto a suitable threaded connection (15) provided on a frame part (14) of the bicycle such that, when the connecting screw (16) is firmly mounted, the retaining head (21) is located at a distance from the frame part (14) and is at least partially engaged by the mounting element (20). The clamping element can be wrapped once or several times around the frame part and secured to the retaining head of the connecting screw with the mounting element.Between the clamping device and the frame part, particularly lightweight items to be transported, such as a rain jacket (29), can be quickly and reliably clamped.
