Solution Overview
Problem
Existing fastening systems for attaching containers to bicycle handlebars face challenges in adapting to different handlebar diameters, require complex assembly, and lack reliability, especially on bumpy surfaces and with heavy loads.
Innovation Solution
A fastening system featuring handlebar clamps that can be slipped over the handlebars, combined with a carrying handle and securing means that prevent rotation, allowing for easy assembly and adaptability to various handlebar diameters and ensuring secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fastening systems are used to attach containers to handlebars, then the containers can be secured to the bicycle, but the systems cannot be easily adapted to different handlebar diameters and require complex assembly
Solution Approach 1:
The fastening system is divided into separate components: handlebar clamps that can be independently adjusted and a carrying handle assembly. This segmentation allows the clamps to be adapted to different handlebar diameters without redesigning the entire system, simply by adjusting or replacing the clamp components.
Solution Approach 2:
The handlebar clamps are designed with a universal adjustment mechanism that can accommodate various handlebar diameters and shapes. The clamps can be positioned at different locations on the handlebar and adjusted to fit different container sizes, making the system multi-functional and highly adaptable.
2Ease of operation
If traditional fastening systems are used, then containers can be attached to handlebars, but the assembly process is time-consuming and not user-friendly
Solution Approach 1:
The handlebar clamps are pre-adjusted to common handlebar diameters during manufacturing, and the receiving section is pre-configured with alignment features. This preliminary preparation allows users to simply slide the clamps onto the handlebar and secure them without requiring complex adjustment procedures, significantly reducing assembly time.
Solution Approach 2:
The clamps incorporate self-aligning features and automatic positioning mechanisms that guide the assembly process. The receiving section automatically aligns with the clamp positions, and the securing means engage automatically when the container is placed, eliminating the need for precise manual alignment and reducing assembly complexity.
3Reliability
If traditional fastening systems are used, then containers can be mounted on handlebars, but the attachment is unreliable and allows rotation, especially with heavy loads or on bumpy surfaces
Solution Approach 1:
Multiple securing functions are merged into a single integrated mechanism: the clamps provide radial clamping force, the receiving section provides axial positioning, and the securing means provide rotational locking. This combination of functions in one system ensures reliable attachment that prevents rotation even under heavy loads or on bumpy surfaces.
Solution Approach 2:
The receiving section acts as an intermediary element between the clamps and the container. It translates the radial clamping force from the clamps into axial positioning and rotational locking, ensuring that the container is securely held without rotation. This intermediary mechanism distributes forces evenly and prevents rotational movement.

AI summary
The invention relates to a fastening system for attaching containers such as bags or baskets to the handlebars (100) of a bicycle, comprising at least one, preferably two, handlebar clamps (2) which can be slipped over the handlebars (100) in a slip-on direction (Ru) and which, in the slipped position, at least partially encircle the handlebars (100), and a carrying bracket (4) comprising a coupling element (6) on the side of the carrying bracket for receiving the container, which is arranged on a projecting section (8) of the carrying bracket (4), wherein the carrying bracket (4) further comprises a receiving section (10) which can preferably be brought into coupling engagement with the handlebar clamps (2) opposite to the slip-on direction (Ru) and can thus preferably be positioned in a fixed position on the handlebars (100) by clamping them in place, further comprising at least one securing means (50),which is essentially force-coupled between the cantilevered section (8) and a component of the bicycle other than the handlebar (100) and preferably a steering stem (102), so that a rotation of the cantilevered section (8) relative to the handlebar (100) is prevented.
