Bicycle Bag Folding Hook With Low-Protrusion Resting Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle bags with folding hooks often have protrusions that can snag on clothing or other items and are not designed to minimize these protrusions in their resting position, leading to potential hazards and aesthetic issues.
Innovation Solution
A bicycle bag with folding hooks featuring pivotable and movable hook parts that can transition between a resting and working position, with a design that minimizes protrusions in the resting state, using a guide and actuating element for smooth operation and secure attachment to a bicycle rack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the folding hook is designed with two movable hook parts to enable secure attachment to rack struts, then the holding capability is improved, but the protrusion in resting position increases causing snagging hazards
Solution Approach 1:
The second hook part is nested within the first hook part when both are in the retracted position. The guide structure allows the second hook part to slide along the first hook part, enabling compact nesting that minimizes protrusion while maintaining the capability to deploy both hooks for secure rack attachment
Solution Approach 2:
The folding hook employs dynamic movement of both hook parts between retracted and deployed positions. The actuating element enables controlled deployment where the second hook part slides along the guide on the first hook part, allowing the structure to adapt between compact storage and functional states
2Adaptability or versatility
If both hook parts are made movable to improve adaptability to different rack struts, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The folding hook is segmented into two independent movable hook parts, each capable of individual movement along the guide structure. This segmentation allows each part to independently adapt to different strut configurations while sharing a common guide mechanism, reducing overall system complexity compared to a fully independent dual-hook design
Solution Approach 2:
The guide structure serves multiple functions: it guides the movement of the second hook part along the first hook part, provides structural support, and enables both hook parts to work together as a unified attachment mechanism for various rack strut types and diameters
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 design ensures minimal protrusion in the resting position, preventing snagging and enhancing safety and aesthetics while providing secure attachment to various rack strut diameters, allowing easy attachment and removal of the bag.
Implementation Method 1
the first hook part (3) is pivotable relative to the bag, and the second hook part (1) is movable both relative to the bag and relative to the first hook part (3)
Implementation Method 2
the second hook part (1) is guided and slid along a guide (5)
Implementation Method 3
Both hook parts can be moved from a rest position to a working position by means of an actuating element, so that the folding hook as a whole can selectively assume either a rest position or a working position

AI summary
In a bicycle bag with a folding hook that is movable between a holding position in which it projects outwards from a rear wall of the bicycle bag and a rest position in which it is inserted further into the bicycle bag than in the holding position, wherein the folding hook has two hook parts movable relative to each other, the invention proposes that a first hook part is movably mounted and a second hook part is slidably guided along a guide, and that the first hook part connects to the second hook part in such a way that the displacement of the second hook part moves the first hook part between the rest position and the operating position.
