Detachable Bag Hook System for Bicycle Luggage Carriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag hook systems for bicycles are not universally applicable, as they often require replacement of the entire bag hook when broken, which can alter the appearance of the bicycle bag, and may not fit luggage carriers with battery packs due to space constraints, limiting compatibility with different models.
Innovation Solution
A detachable bag hook system with an attachment element and a one-piece bag hook featuring equally long legs, including a wedge-shaped locking part, allowing for easy replacement and compatibility with various luggage carriers, including those with limited space between the battery pack and rod.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire bag hook is replaced when broken, then the bag hook can be restored to functional condition, but the appearance of the bicycle bag is altered and the repair process becomes complex
Solution Approach 1:
The bag hook is divided into two separable components: a permanent attachment element that remains fixed to the bicycle bag, and a detachable bag hook portion that can be easily replaced. This segmentation allows the attachment element to remain intact while only the removable portion needs replacement, simplifying the repair process and maintaining the bag's appearance.
Solution Approach 2:
The bag hook portion is extracted as a separate removable component from the attachment element. This extraction enables the bag hook to be easily detached and replaced without affecting the attachment element that is permanently fixed to the bag, thus simplifying repair while preserving the bag's appearance.
2Adaptability or versatility
If a known bag hook is used, then the bag hook can be attached to the luggage carrier rod, but it cannot be attached to luggage carriers with battery packs due to space constraints
Solution Approach 1:
The bag hook is designed with adjustable parameters, specifically the distance between the attachment element and the locking element can be varied. This allows the bag hook to be adapted to different space constraints, enabling compatibility with both standard luggage carriers and those with battery packs that have limited space.
3Strength
If the bag hook is made as a single integrated piece, then the structure is simple and robust, but it cannot be easily replaced when broken
Solution Approach 1:
The bag hook system is segmented into a permanent attachment element and a removable bag hook portion. The attachment element remains fixed to maintain structural integrity, while the removable portion can be easily replaced when broken, combining the benefits of both a single-piece robust structure and easy replaceability.
4Strength
If screws and rivets are used to attach the bag hook to the bicycle bag, then the attachment is strong, but the repair process requires complex interventions on the rear wall
Solution Approach 1:
The attachment system is segmented into a permanent attachment element that is securely fixed to the bicycle bag using screws or rivets, and a removable bag hook portion. This allows the attachment element to maintain strong attachment while the removable portion can be replaced without requiring complex interventions on the bag's rear wall.
