Bicycle Bag Attachment Rail for Shopping Bags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shopping bags are not suitable for suspension on bicycle racks due to inadequate durability and center of gravity alignment, leading to swinging and potential entanglement with the wheel, while durable bicycle bags are expensive and not disposable.
Innovation Solution
A bicycle bag with a bag attachment rail featuring elongated body portions and suspension hooks attached to a soft pliable sheet material shopping bag, allowing easy fixation and adjustment to prevent entanglement, and a detachable attachment system for reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shopping bags are used for bicycle transportation, then cost is reduced and disposability is improved, but durability is insufficient and entanglement with wheels occurs
Solution Approach 1:
The patent combines a shopping bag with a bicycle attachment rail system, merging the disposable bag with a durable attachment mechanism. The attachment rail with suspension hooks integrates the bag securely to the bicycle rack, providing both the low cost of disposable bags and the reliability of a proper attachment system.
Solution Approach 2:
The attachment rail acts as an intermediary between the shopping bag and the bicycle rack. This mediator component provides the necessary durability and secure connection, while the shopping bag itself remains simple and disposable. The rail system with its elongated body and suspension hooks mediates the connection, preventing direct attachment issues.
2Ease of operation
If shopping bag handles are used for suspension, then simplicity is maintained, but center of gravity alignment is poor causing swinging and entanglement
Solution Approach 1:
The patent extracts the suspension function from the shopping bag handles themselves and transfers it to the attachment rail system. The handles remain simple for carrying, while the dedicated attachment rail with suspension hooks provides the proper suspension point that aligns with the bicycle rack, eliminating swinging and entanglement issues.
Solution Approach 2:
The attachment rail system copies the essential suspension function needed for bicycle attachment, but implements it through a separate, optimized structure rather than relying on the original bag handles. The suspension hooks replicate the hanging function in a way that is specifically designed for bicycle rack compatibility.
3Reliability
If durable bicycle bags are used, then durability and balance are improved, but cost increases and reusability is required
Solution Approach 1:
The patent segments the bicycle bag system into two parts: a durable attachment rail that remains with the bicycle, and a disposable shopping bag that can be replaced. This segmentation allows the expensive durable components to be reused while the simple bags can be disposed of after single use, combining the benefits of both approaches.
Solution Approach 2:
The attachment rail system is designed to be recovered and reused with multiple different shopping bags. The durable rail remains with the bicycle while the shopping bags can be discarded after use. This allows recovery of the expensive components while discarding the simple, replaceable bags.
4Stability of the object's composition
If fixed attachment methods are used, then stability is improved, but attachment and removal time increases and tools may be required
Solution Approach 1:
The attachment system transitions from static fixed attachment to dynamic adjustable attachment. The suspension hooks can be positioned at different locations on the elongated body of the rail, allowing the attachment point to be adjusted for optimal balance and stability while maintaining quick attachment and removal capability.
Solution Approach 2:
The system allows changing the attachment parameters by adjusting the position of suspension hooks along the elongated body. This parameter adjustment enables optimization of both stability and attachment speed, providing configurable attachment points that can be adapted to different bag and rack configurations.

AI summary
The invention provides a bicycle bag comprising a shopping bag and a bag attachment rail for suspension of the bicycle bag on a bicycle. The bag attachment rail comprises an elongated body portion forming a front face, an opposite rear face, an upper edge and a lower edge extending between first and second end portions, and bicycle attachment means forming at least one suspension hook. The shopping bag forms space for carrying shopping items between a front layer and a rear layer of a soft pliable sheet material. To provide easy attachment e.g. on a rack of a bicycle and for providing good balance, the bag attachment rail is attached to the front layer of the shopping bag.
