Rear Bicycle Rack with Universal Mounting Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle rack systems require significant time and effort for installation and removal, and often necessitate different tools for various auxiliary devices, leading to compatibility issues and inefficiencies in mounting and unmounting cargo and passenger seats.
Innovation Solution
A rear-mounted bicycle rack system with a main frame that attaches over the rear wheel, featuring a top platform and lower deck for interchangeable auxiliary devices, using a uniform set of connectors for easy assembly and disassembly, allowing for the accommodation of cargo decks, passenger seats, and other accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple auxiliary devices are mounted on a bicycle using conventional methods, then cargo and passenger carrying capability is improved, but installation time and effort increase significantly
Solution Approach 1:
The patent implements a universal mounting system where a single main frame structure supports multiple types of auxiliary devices (cargo decks, passenger seats, child seats) through standardized mounting interfaces. The top platform and lower deck provide common mounting locations that can accommodate different device types without requiring separate mounting structures for each device type.
Solution Approach 2:
The mounting system is divided into separate modular components: a main frame that attaches to the bicycle, a top platform with mounting locations, and a lower deck with additional mounting locations. Auxiliary devices can be independently attached or removed from these modular components, allowing for quick configuration changes without reinstalling the entire mounting structure.
2Adaptability or versatility
If different auxiliary devices from various manufacturers are mounted on a bicycle, then device functionality is improved, but compatibility and interchangeability problems arise requiring different tools
Solution Approach 1:
The patent provides a universal mounting interface that can accommodate multiple types of auxiliary devices through standardized attachment points on the top platform and lower deck. The system uses consistent mounting mechanisms (such as straps, clips, or quick-release interfaces) that work with different device types from various manufacturers, eliminating the need for device-specific tools or mounting procedures.
3Adaptability or versatility
If one auxiliary device is mounted on a bicycle, then carrying capability is improved, but removing it prevents mounting another auxiliary device without considerable time and effort
Solution Approach 1:
The mounting system separates the permanent main frame structure from the removable auxiliary devices. The main frame remains attached to the bicycle, while auxiliary devices can be independently removed or attached to the top platform and lower deck mounting locations. This segmentation allows for quick device changes without disturbing the base mounting structure.
Solution Approach 2:
The main frame and mounting structure are pre-installed on the bicycle in advance, creating a permanent base that remains in place. This preliminary action eliminates the need to repeatedly install and remove the entire mounting structure when changing auxiliary devices, as only the removable devices themselves need to be attached or detached from the pre-positioned mounting locations.

AI summary
A bicycle rack system comprises a main frame configured to be mounted over a rear wheel of a bicycle. The main frame comprises a top platform for accommodating one or more first auxiliary devices, the top platform having a first platform section and a second platform section, at least one of the first and second platform sections configured to accommodate the first auxiliary device, and a lower deck for accommodating one or more second auxiliary devices, the lower deck having a first deck section and a second deck section, at least one of the first and second deck sections configured to accommodate the second auxiliary device.
