Bicycle Support for Travel Pack with Pivotable Shelf
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Carrying luggage on a bicycle can be cumbersome and strain the rider due to shifting weight, and existing bicycle bag attachments are often bulky or inconvenient, limiting the rider's experience.
Innovation Solution
A modular bicycle attachment system featuring adjustable support beams and a pivotable shelf that straddles the rear tire, allowing for secure attachment of packs and adjustable positioning to alleviate weight strain and enhance convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rider-worn bag is used to carry luggage, then the bag can be easily attached to the rider, but the weight shifts during riding and increases the difficulty of the ride
Solution Approach 1:
The patent introduces a bicycle-mounted support structure as an intermediary between the rider and the luggage. The support includes a vertical post attached to the bicycle frame and a horizontal shelf that extends outward, creating a stable intermediate platform. This intermediary structure bears the luggage weight independently, preventing weight transfer to the rider while maintaining easy attachment to the bicycle.
Solution Approach 2:
The support structure is segmented into distinct functional components: a vertical support post, a horizontal shelf, and attachment mechanisms. This segmentation allows each component to perform its specific function optimally - the post provides vertical support, the shelf provides a stable platform, and the attachment mechanisms secure the structure to the bicycle. The modular design also enables easy assembly and adjustment.
2Reliability
If known bicycle bag attachments are used, then the bags can be attached to the bicycle, but they are bulky, inconvenient, and allow the bag to get in the way of the rider
Solution Approach 1:
The shelf is designed to be pivotally connected to the vertical post, allowing it to rotate between a horizontal position (for luggage support) and a vertical position (for storage against the bicycle frame). This dynamic capability enables the shelf to adapt to different riding conditions and rider needs, providing stability when needed and clearing the rider's path when not in use. The pivot mechanism maintains secure attachment while enabling flexible operation.

AI summary
An attachment for a bicycle is provided to facilitate travel with a pack, such as a backpack or messenger bag, without requiring the entirety of the load to be carried by the body of the user. The attachment is capable of being coupled to bicycles across different types and sizes and is further capable of being adjusted to fit the needs of individual users. Additionally, the bicycle attachment may provide a convenient way to attach other accessories to the bicycle.
