Adaptable Bicycle Mudguard with Stepped Splash Guard Offset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mudguards are not versatile enough to accommodate both bicycles with and without spring-loaded front forks, as they are designed for specific fork types and lack adaptability.
Innovation Solution
A mudguard design featuring two splash guard parts that can be arranged in either a continuous configuration or a configuration with a stepped offset, allowing for flexible attachment to different types of front forks through adjustable fastening parts with angled legs that can be assembled symmetrically or asymmetrically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mudguard is designed with a stepped offset to accommodate spring-loaded front forks, then it can be attached to bicycles with spring-loaded front forks, but it cannot be used for bicycles without spring-loaded front forks
Solution Approach 1:
The mudguard incorporates a movable connection between the first and second splash guard parts, allowing the structure to dynamically adjust between a continuous configuration (for non-spring forks) and a stepped offset configuration (for spring-loaded forks). This dynamic adaptability resolves the contradiction by enabling the same structure to serve multiple fork types without permanent structural complexity
Solution Approach 2:
The mudguard is divided into separate splash guard parts that can be independently positioned and connected. This segmentation allows the parts to be arranged in different configurations (continuous or stepped) depending on the fork type, providing versatility without requiring a completely different design for each application
2Adaptability or versatility
If the mudguard is designed without a stepped offset for continuous splash protection, then it works for bicycles without spring-loaded front forks, but it cannot be properly attached to bicycles with spring-loaded front forks
Solution Approach 1:
The movable connection enables the mudguard to dynamically switch between continuous and stepped configurations, ensuring reliable attachment for spring-loaded forks when needed while maintaining compatibility with non-spring forks in the continuous configuration
Solution Approach 2:
The mudguard design achieves multi-functionality by incorporating adjustable connections that allow the same structure to properly attach to both spring-loaded and non-spring-loaded front forks, eliminating the need for fork-type-specific designs

AI summary
The guard has an attachment unit (2) e.g. bolt, with which the guard is attached to a part of a bicycle. A splash guard portion (1) is connected indirectly or directly with the unit (2). The portion has a slotted hole (6) that extends in a longitudinal direction of the portion and serves indirect or direct connection with the unit (2). The portion is positioned through the slotted hole in different positions relative to the rear wheel.
