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 often interfere with suspension and disc brake setups, and do not allow for versatile or secure load carrying, particularly off-road.
Innovation Solution
A system comprising a mounting part with an axially extending member and transversely projecting lugs, and a receiving part with a recess and locking mechanism that allows for angular positioning and secure retention of accessories, enabling versatile mounting on various cycle components without the need for traditional carrier racks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wire carrier racks are used to mount panniers, then secure load carrying is achieved, but the system becomes bulky and heavy
Solution Approach 1:
The mounting system is divided into separate components: a mounting part that attaches to the cycle and a receiving part that holds the accessory. This segmentation allows each component to be optimized independently, eliminating the need for a complete traditional wire rack structure while maintaining secure mounting capability.
Solution Approach 2:
The essential mounting function is extracted from the bulky traditional wire rack structure. The patent uses a simplified mounting part with an axially extending member and radially inwardly extending teeth that engage with a receiving part, removing unnecessary structural elements while preserving the core function of secure accessory retention.
2Adaptability or versatility
If traditional wire carrier racks are used, then panniers can be mounted, but compatibility with all cycle types is limited
Solution Approach 1:
The mounting part is designed with a universal attachment mechanism that can be installed on various cycle types including those without eyelets, carbon fiber frames, and cycles with suspension or disc brakes. The axially extending member with engagement teeth provides a standardized interface that works across different cycle configurations while maintaining secure mounting reliability.
3Reliability
If traditional wire carrier racks are installed, then load carrying capacity is sufficient, but interference with suspension and disc brake setups occurs
Solution Approach 1:
The mounting system uses a localized attachment approach where the mounting part is installed at specific locations on the cycle (such as on the frame or fork) rather than requiring a complete wire rack structure. This localized mounting minimizes interference with suspension components and disc brake setups while maintaining sufficient load carrying capacity through the engineered engagement between the mounting part's teeth and the receiving part.

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).
