Bicycle Bag Adjustable Belt Assembly for Versatile Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle bags are limited in their attachment options, only allowing attachment between the bicycle saddle and seat post, failing to meet user needs for versatile placement.
Innovation Solution
A bicycle bag with a bag body and at least one adjusting belt assembly, featuring penetration portions and a belt member with a buckle, allowing selective attachment to various bicycle components such as the up tube, seat post, or between the saddle and seat post.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bicycle bag uses a fixed attachment structure between saddle and seat post, then the attachment reliability is ensured, but the adaptability to different bicycle configurations is reduced
Solution Approach 1:
The belt assembly is divided into multiple segments including a first belt portion, second belt portion, third belt portion, and fourth belt portion that can be independently adjusted and configured. This segmentation allows the bag to be attached at various positions on the bicycle while maintaining secure fastening at each segment.
Solution Approach 2:
The belt assembly incorporates adjustable and foldable components that can dynamically adapt to different bicycle configurations. The belts can be extended, contracted, repositioned, and folded to accommodate various attachment scenarios, transforming a static structure into a dynamic one that responds to different user needs.
2Adaptability or versatility
If the bicycle bag uses multiple adjustable belt assemblies with penetration portions, then the adaptability to different bicycle parts is improved, but the device complexity increases
Solution Approach 1:
The belt assembly is designed as a universal attachment system that can be used with multiple types of bicycle components (saddle, seat post, up tube, handlebar, etc.). The same belt structure serves multiple functions by simply changing the attachment points, eliminating the need for different attachment mechanisms for different locations.
Solution Approach 2:
The belt portions are designed to nest within each other when not in use, with folding portions that can be stored inside the bag body or along the belt path. This nesting reduces the overall space required and simplifies the apparent complexity when the system is not fully deployed.
3Ease of operation
If the belt assembly includes multiple folding portions and connecting portions, then the ease of adjustment is improved, but the structural complexity increases
Solution Approach 1:
The belt assembly comes pre-configured with folding portions and connecting portions at specific locations, so that users do not need to create adjustment points during installation. The folding portions are pre-positioned to allow quick adjustment to common attachment scenarios, reducing the cognitive load and time required for setup.

AI summary
A bicycle bag includes a bag body and at least one adjusting belt assembly. The bag body is adapted to store bicycle accessories and includes a first penetration portion and a second penetration portion. The at least one adjusting belt assembly is selectively inserted through one of the first and second penetration portions to form a suspending portion attachable to a bicycle. Thus, the bicycle bag can be attached to an up tube or a seat post of a bicycle, or attached between the saddle and the seat post of a bicycle to meet user needs.
