Bicycle Saddle Angle Locking Structure for Stable Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bicycle saddles are cumbersome and difficult to adjust, especially when ridden on bumpy roads, as they require multiple components and screws, which can lead to instability and risk of fracture.
Innovation Solution
An angle adjustable bicycle saddle design featuring a seat post with tooth-shaped protrusions and a cushion with engagement portions, combined with a locking unit using fixing elements and stepped nuts, allowing for easy angular adjustment and secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple screws and nuts are used to fix the cushion to the seat post, then the connection strength is improved, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent combines multiple fastening functions into a single integrated clamp structure. The clamp simultaneously performs clamping, positioning, and locking functions that previously required separate screws and nuts, thereby reducing component count while maintaining connection strength
Solution Approach 2:
The clamp is designed as a multi-functional component that can adjust both the position and angle of the cushion while providing secure fixation. This universal component replaces multiple specialized fasteners, simplifying the overall structure
2Strength
If the seat post is reinforced to prevent fracture, then the strength is improved, but the device complexity and weight increase
Solution Approach 1:
The clamp is pre-installed on the seat post with built-in reinforcement features. This preliminary preparation allows the standard seat post to withstand loading forces without requiring additional reinforcement structures, maintaining simplicity while ensuring strength
3Adaptability or versatility
If multiple adjustment mechanisms are added to enable angle adjustment, then the adaptability is improved, but the ease of operation deteriorates
Solution Approach 1:
The clamp incorporates a quick-release mechanism that allows the cushion angle to be dynamically adjusted between fixed positions. The mechanism transitions from a locked state to an adjustable state with a simple operation, making angle changes quick and easy
Solution Approach 2:
The adjustment mechanism is divided into discrete angular positions marked on the clamp, allowing users to easily select and reproduce specific angles. This segmentation provides adaptability while maintaining operational simplicity through visual guidance

AI summary
An angle adjustable bicycle saddle contains a seat post, a cushion, and a locking unit. The seat post includes an inwardly curved groove having multiple protrusions, and the seat post includes multiple troughs. The cushion includes a body and a cap. The body has a curved holder, an arcuate abutting projection, multiple engagement portions, and multiple through holes corresponding to the multiple troughs. The cap is covered on the curved holder of the body so that the curved holder has a hollow portion. The locking unit includes multiple fixing elements and multiple stepped nuts. A respective fixing element is inserted through a respective trough and a respective through hole. A first end of a respective fixing element is adjustably received in a respective trough, and a second end of the respective fixing element is accommodated in the hollow portion of the curved holder.
