Bicycle Saddle Post Angle Locking for Dynamic Ride Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cyclists face challenges in adjusting the height and angle of their bicycle saddles during rides, particularly when transitioning between uphill and downhill positions, as existing systems either fail to provide adequate adjustment or result in clothing entanglement and potential injury.
Innovation Solution
A bicycle saddle adjustment system featuring an adjustable height saddle post with a saddle angle adjustment mechanism that allows the saddle to rotate relative to the body as the height is changed, incorporating a rotating assembly and a mechanism to lock the saddle in specific positions, enabling the rider to adjust the saddle angle dynamically while riding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the saddle height is lowered when going downhill, then the saddle may catch the rider's clothing or cause injury, but lowering the saddle reduces power efficiency and comfort
Solution Approach 1:
The saddle angle is made dynamically adjustable through a rotation mechanism that allows the saddle to change its angle relative to the saddle post. The saddle support assembly includes a rotation mechanism with a first position (level angle) and a second position (backward angle), enabling the system to adapt to different riding conditions and resolve the contradiction between safety and comfort.
2Ease of operation
If the saddle angle is adjusted forward when raised and backward when lowered, then rider comfort is improved, but the mechanism complexity increases
Solution Approach 1:
The rotation mechanism is integrated into the existing saddle post assembly, merging the angle adjustment function with the height adjustment structure. The saddle support assembly combines the saddle support, rotation mechanism, and locking mechanism into a unified structure that leverages the existing saddle post, thereby reducing overall system complexity while providing advanced functionality.
Solution Approach 2:
The rotation mechanism is designed to be automatically actuated by the rider's body movement and weight transfer. When the rider shifts position or applies pressure, the mechanism self-activates to rotate the saddle to the appropriate angle, eliminating the need for separate controls or complex actuation systems.
3Stability of the object's composition
If a locking mechanism is added to secure saddle positions, then stability is improved, but the device complexity and ease of operation are reduced
Solution Approach 1:
The locking mechanism is designed as a spring-loaded automatic locking system that engages and disengages based on the rider's actions. When the rider applies force to adjust the saddle, the mechanism automatically locks into position without requiring separate locking actions. The spring-loaded design provides automatic engagement and disengagement, maintaining stability while preserving ease of operation.

AI summary
A bicycle assembly comprises a saddle adjustment assembly, the saddle adjustment assembly comprising an adjustable height saddle post, the adjustable height saddle post comprising first and second slidably coupled supports; a saddle post locking mechanism that selectively restricts sliding of the second support relative to the first support; and a saddle angle adjustment mechanism configured to couple to a bicycle saddle to enable rotation of the bicycle saddle between a first predetermined position and a second predetermined position, wherein, when the saddle post locking mechanism is in an unlocked configuration, the saddle angle adjustment mechanism enables rotation of the bicycle saddle between the first and second predetermined positions, and wherein, when the saddle post locking mechanism is in a locked configuration, the saddle angle adjustment mechanism maintains the bicycle saddle in one of the first and second predetermined positions.
