Movable Outer Hook for Bicycle Luggage Carriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle luggage carrier systems are not designed for high carrying comfort when the luggage is not attached to the carrier, as the hooks can catch on clothing, leading to discomfort during hand carrying.
Innovation Solution
The outer hook is made movable to transition between a receiving/holding position and a carrying position, where it is closer to the luggage wall or dips inside, preventing catching and enhancing comfort, along with adjustable and lockable mechanisms for secure attachment to various luggage carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outer hook is extended away from the wall to enable secure attachment to the luggage carrier, then the attachment reliability is improved, but the carrying comfort deteriorates due to the hook catching on clothing
Solution Approach 1:
The outer hook is designed to be movable relative to the luggage wall, transitioning between a first position for secure attachment to the luggage carrier and a second position closer to the wall for comfortable hand carrying. This dynamic repositioning allows the hook to adapt its configuration based on operational requirements, resolving the contradiction between attachment reliability and carrying comfort
Solution Approach 2:
The position parameter of the outer hook is changed between two states: extended away from the wall for attachment and retracted closer to the wall for carrying. By modifying the spatial parameter of the hook's position, the system achieves both secure attachment when needed and comfortable carrying when the hook is retracted
2Ease of operation
If the outer hook is made movable to improve carrying comfort, then the carrying comfort is improved, but the device complexity increases
Solution Approach 1:
The outer hook is combined with the luggage wall through a movable connection that integrates both functions: secure attachment when extended and comfortable carrying when retracted. By merging these two states into a single integrated component rather than separate parts, the design achieves functionality without excessive complexity
Solution Approach 2:
The hook system is segmented into the outer hook and the inner hook, where the outer hook provides the movable attachment function and the inner hook provides the receiving function. This segmentation allows each component to be optimized for its specific function while working together as a cohesive system
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
The solution significantly improves carrying comfort by preventing hooks from catching on clothing and allows for easy, secure attachment and detachment from luggage carriers, adapting to different geometries without frequent adjustments.
Implementation Method 1
Spring-loaded, the inner hook assumes a so-called holding position close to the outer hook
Implementation Method 2
A tension element can be used to pivot the inner hook away from the outer hook against the action of the spring
Implementation Method 3
The proposed configuration of the hook prevents the outer hook from catching, for example, on the user's clothing when the user is carrying the piece of luggage as hand luggage

AI summary
In a luggage item of a bicycle luggage carrier system, wherein the bicycle luggage carrier system comprises a luggage carrier attached to a bicycle, the luggage carrier has a strut, and the luggage item has an interior enclosed by walls and a hook on one of the walls, and wherein the hook has a first, outer section further away from the wall, referred to as the outer hook, and a second, inner section closer to the wall of the luggage item, referred to as the inner hook, and wherein the inner hook and the outer hook together form an eyelet in a so-called holding position which engages the strut of the luggage carrier, and wherein the inner hook is movable from the holding position into a receiving position, such that the free ends of the outer hook and inner hook are spaced apart from each other to enable the hook to be placed on the strut, the invention proposesthat the outer hook is movable from the receiving and holding position into a carrying position in which the free end of the outer hook is arranged essentially in the plane of the wall of the piece of luggage or within the contour enclosed by the piece of luggage.
