Mudguard Bracket With U-Shaped Element and Collars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mudguards on bicycles lack adequate support, leading to deformation and instability due to inadequate attachment to the fork or chain-stay/seat-stay.
Innovation Solution
A robust bracket system comprising a U-shaped element, collars, and nuts is used to securely attach the mudguard to the bicycle frame via a skewer, ensuring firm fixation and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two rods are used to attach the mudguard to the fork or chain-stay/seat-stay, then the attachment structure is simple, but the mudguard receives inadequate support and can easily be biased and/or deformed
Solution Approach 1:
The bracket is divided into multiple functional segments: a U-shaped element with two branches for attachment to the fork/chain-stay, an arched section for attachment to the mudguard, and two collars positioned between them. This segmentation allows each part to perform its specific function optimally, distributing the support load across multiple points rather than relying on simple rod attachments.
Solution Approach 2:
The bracket transitions from simple linear rod attachments to a three-dimensional U-shaped structure with branches extending in different directions. The U-shaped element with its arched section creates a spatial framework that provides support in multiple dimensions, preventing bias and deformation more effectively than linear rods alone.
2Reliability
If a robust bracket system with U-shaped element, collars, and nuts is used to securely attach the mudguard, then the support and stability are enhanced, but the device complexity increases
Solution Approach 1:
The bracket merges multiple components (U-shaped element, collars, nuts) into a unified attachment system that works together as an integrated whole. The collars are positioned to receive the skewer, while the U-shaped element provides the structural framework, and the nuts secure the assembly. This merging creates a reliable system where each component reinforces the others, providing enhanced stability despite the increased number of parts.
Solution Approach 2:
The collars act as intermediary elements between the U-shaped element and the skewer. They receive the skewer and distribute the attachment forces, mediating the connection between the bracket structure and the mudguard mounting system. This intermediary function enhances reliability by providing a dedicated interface for force transmission.

AI summary
A bracket includes a U-shaped element, two collars and two nuts. The U-shaped element includes an arched section formed between two branches. The arched section of the U-shaped element is attached to a mudguard. The collars are respectively secured to the branches of the U-shaped element. The collars are operable to receive two sections of a skewer. The nuts are operable for engagement with two threaded sections of the skewer.
