Non-segmented Bicycle Mudguard with Continuous Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mudguards for bicycle front wheels face challenges in precise positioning due to segmentation, which complicates production and operation, especially on mountain bikes with spring-loaded front wheel forks, requiring accurate distance maintenance from the down tube and tire.
Innovation Solution
A non-segmented mudguard design with continuous adjustability through non-positive connecting means, such as sleeves and screws, allowing precise positioning of the rear end without segmentation, enabling stepless angle adjustment and simplified manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the second splash guard part is segmented with interlocking teeth for angle adjustment, then the mudguard can be adjusted to different angles in steps, but the positioning precision of the rear end is insufficient and the structure becomes complex
Solution Approach 1:
The mudguard is divided into two parts: a first splash guard part and a second splash guard part. The second part is made as a single non-segmented piece rather than multiple adjustable segments, which simplifies the structure while maintaining adjustability through the connection mechanism between the two parts.
Solution Approach 2:
The connection between the two splash guard parts uses a dynamic adjustment mechanism with a pivot point and adjustable fastening system. This allows the angle between the two parts to be continuously varied and fixed at any desired position, providing both adaptability and precise positioning capability.
2Adaptability or versatility
If multiple connecting segments with intermeshing teeth are used to adjust the angle, then the mudguard can adapt to different positions, but the production process becomes complex and operation is complicated
Solution Approach 1:
The mudguard is divided into two main parts connected by a simplified connection mechanism. The second part is kept as a single non-segmented piece, reducing the number of components while maintaining adjustability through the connection system.
Solution Approach 2:
The adjustment and fastening functions are combined into a single connection mechanism that uses a pivot point with an adjustable fastening system. This integrates multiple functions into one mechanism, simplifying both the structure and the operation compared to using separate adjustment segments.
3Manufacturing precision
If the second splash guard part is made non-segmented with continuous adjustability, then the positioning precision is improved and production is simplified, but the connection mechanism must provide continuous adjustment capability
Solution Approach 1:
The connection mechanism uses a dynamic pivot-based system that allows continuous angular adjustment between the two splash guard parts. The fastening system can be adjusted to any position along the adjustment range and secured, providing continuous positioning capability without requiring multiple discrete segments.
Solution Approach 2:
The complex interlocking teeth mechanism is removed and replaced with a simpler pivot-based connection system. The essential function of angle adjustment is extracted and implemented through a more straightforward mechanical connection that allows continuous movement and positioning.
