Handlebar Transport Device Using Elastic Cord Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport devices for two-wheeled vehicles, such as bicycles, are either too heavy, require pre-decision and frequent attachment/removal, or significantly alter the vehicle's appearance.
Innovation Solution
A lightweight transport device utilizing the vehicle's handlebar and handlebar mount with minimal additional components, featuring three fastening elements and a fixing element, such as an elastomer cord, to securely attach articles without altering the vehicle's appearance or requiring extensive setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixedly mounted transport devices (racks, bicycle baskets) are used, then transport capacity is improved, but device weight increases significantly
Solution Approach 1:
The transport device is segmented into minimal essential components: three fastening elements attached to the handlebar and a separate fixing element for the article. This segmentation eliminates unnecessary structural components, reducing weight while maintaining transport functionality for small items.
Solution Approach 2:
The device transitions from a static, fixed mounting structure to a dynamic, flexible system using elastic fixing elements and simple fastening points. This allows the device to be easily attached and removed while providing secure transport when in use, adapting to the user's immediate needs without permanent installation.
2Weight of moving object
If removable transport devices (panniers, saddlebags) are used, then device weight is reduced, but attachment and removal operations become frequent and time-consuming
Solution Approach 1:
The three fastening elements are pre-attached to the handlebar in a simple configuration, eliminating the need for complex assembly during each use. The fixing element can be quickly connected to these pre-positioned fastening points, significantly reducing attachment time while maintaining removability.
3Adaptability or versatility
If traditional transport devices are mounted, then transport functionality is achieved, but vehicle appearance is significantly altered
Solution Approach 1:
The invention extracts only the essential functional elements needed for transport (three fastening points and a fixing element) while removing all non-essential structural components. This minimalistic approach attaches the transport function to the vehicle without adding bulky racks, baskets, or frames that would alter the vehicle's appearance.
4Weight of moving object
If minimal components are used, then device weight is reduced and appearance is preserved, but securing reliability must be maintained
Solution Approach 1:
The fixing element is made from elastomer material that combines flexibility with reliable securing capability. The elastic properties allow the fixing element to conform to the article being transported while maintaining sufficient friction and tension to secure it reliably, compensating for the minimal number of components used.

AI summary
A device to fix a smaller object (a book, rolled up articles of clothing, a fabric bag, newspaper, lunch box or the like) to be transported securely on the handlebar and or the handlebar support of a vehicle, in particular a two-wheeled vehicle and more particularly a bicycle. The transport device has three fixing elements (3) which are fixedly attached to the handlebar (1) and/or the handlebar support (2). Each of the fixing elements (3) is provided with a retaining device (4) (ring, figure-of-eight ring, eye, tab or the like), through which a securing element (5) is movably fed. The fixing element (5) can be elastic (e.g. rubber or the like), or inelastic (e.g. cable, belt, tie-down strap, chain or the like). The fixing element (5) is fed twice through the retaining devices (4) such that an object can be fixed easily and then transported by being gripped between the at least two layers of the fixing element (5). The fixing element (5) can be fed through a cord stopper (6) and securely tied off with a knot or the like (7). The fixing element (4) can be tightened by the cord stopper (6), thus assisting, if necessary, in securing the object. The transport device has an extremely economical use of materials and is extremely low weight. The device does not significantly alter the appearance of the vehicle and can be fastened to the vehicle without drilling or adhesive bonding.
