Cycle Accessory Mount With Angular Locking for Rack-Free Load Carrying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cycle accessory mounting systems are limited by the need for bulky and heavy wire carrier racks, which are not compatible with all cycle types, especially those without eyelets or with carbon fiber frames, and traditional panniers can interfere with brake and gear cables, and do not allow for versatile load distribution.
Innovation Solution
A system comprising a mounting part with an axially extending member and transversely projecting lugs, a receiving part with a recess and lip for angular adjustment, and a locking member for secure attachment to various cycle components, enabling easy attachment and versatile positioning of accessories like bags and carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wire carrier racks are used to mount panniers, then the panniers can be securely mounted, but the system becomes bulky and heavy
Solution Approach 1:
The patent extracts the essential mounting function from the traditional wire carrier rack system. Instead of using a complete rack structure, the invention uses individual mounting brackets that attach directly to the cycle frame at specific points, separating the mounting function from the supporting structure.
Solution Approach 2:
The mounting brackets are designed to be universal and adaptable to different cycle types and frame configurations. The brackets can accommodate various tube diameters and shapes, making them suitable for road bikes, mountain bikes, and cycles with carbon fiber frames, eliminating the need for cycle-specific racks.
2Reliability
If traditional wire carrier racks are used, then panniers can be mounted, but the racks are bulky in size
Solution Approach 1:
The patent removes the bulky rack structure and retains only the essential mounting brackets that attach to the frame. This extraction eliminates the need for large horizontal and vertical rack members, significantly reducing the overall size and bulkiness of the mounting system.
Solution Approach 2:
The mounting system is segmented into individual brackets that can be independently positioned at different locations on the frame. This segmentation allows the system to be compact and adaptable, replacing the monolithic rack structure with distributed, space-efficient mounting points.
3Reliability
If traditional carrier racks are installed, then panniers can be mounted, but they cannot be installed on cycles without eyelets or with carbon fiber frames
Solution Approach 1:
The mounting brackets are designed with universal adaptability to work with different frame materials (metal, carbon fiber) and configurations (with or without eyelets). The brackets can be attached using various methods including bolting to frame tubes or integrating with existing frame features, making them compatible across all cycle types.
Solution Approach 2:
The mounting system incorporates adjustable and adaptable features that allow it to conform to different frame geometries and materials. The brackets can be positioned and secured at various locations on the frame, providing dynamic adaptability to different cycle designs including carbon fiber frames that lack traditional eyelets.
4Quantity of substance
If traditional panniers are used, then loads can be carried, but they interfere with brake and gear cables
Solution Approach 1:
The mounting brackets are positioned at specific locations on the frame that are deliberately chosen to avoid cable routing paths. By carefully selecting the local mounting positions and orientations, the system carries loads while maintaining clear pathways for brake and gear cables, eliminating interference.
5Weight of stationary object
If frame-mounted soft bags are used, then they are lightweight and unobtrusive, but they are very limited in load size and very specific to each cycle type
Solution Approach 1:
The mounting brackets provide a universal interface that can accommodate various bag types and sizes across different cycle types. Instead of custom-fit bags for each cycle, the standardized bracket system allows any bag with a corresponding mounting interface to be attached to any cycle, greatly enhancing versatility while maintaining lightweight construction.

AI summary
A system for mounting an accessory to a cycle has a mounting part 400, a receiving part 500, and a locking member 508. The mounting part 400 has an axially extending member 402 and at least one transversely projecting lug 406. The receiving part 500 has a recess for receiving the member 402 and the lug(s) 406 when the receiving part 500 is in a receiving/releasing position, and at least one lip 506 for engaging with the lug(s) 406 to retain the mounting part 400 when the receiving part 500 is angularly moved relative to the mounting part 400. The locking member 508 is operable between the mounting part 400 and the receiving part 500, and is moveable between an unlocked position and a securing position to selectively retain the receiving part 500 in a plurality of angularly offset locked positions relative to the mounting part 400.
