Bicycle Seat Adjustment Mechanism for In-Ride Tilt and Height Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bicycle systems do not allow for efficient adjustment of seat tilt and height while riding, requiring riders to dismount and manually adjust these parameters, which is time-consuming and compromises optimal riding position.
Innovation Solution
A device that enables automatic adjustment of seat tilt and height while the bicycle is in motion, using a seat adjustment mechanism with a tilt actuator and a linear actuator, controlled by a tilt and height controller accessible to the rider.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual seat height adjustment is used, then the rider can adjust the seat position, but the adjustment process is time-consuming and requires dismounting the bicycle
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an automated motor-driven system. The seat post includes a motor assembly that automatically adjusts the seat height based on rider input, eliminating the need for manual dismounting and clamping operations. This substitution of mechanical manual adjustment with automated motor control directly resolves the time loss issue while maintaining ease of operation.
Solution Approach 2:
The automated seat adjustment system allows the bicycle to adjust itself without rider intervention in the physical adjustment process. The rider simply activates the adjustment function, and the motorized system performs the height modification autonomously, making the system serve itself rather than requiring continuous manual operation.
2Ease of operation
If manual seat tilt adjustment is used, then the rider can adjust the seat angle, but the adjustment process is time-consuming and requires dismounting the bicycle
Solution Approach 1:
The patent replaces the manual mechanical tilt adjustment system with an automated motor-driven system. The seat post includes a motor assembly that automatically adjusts the seat tilt angle based on rider input, eliminating the need for manual dismounting and clamping operations. This substitution of mechanical manual adjustment with automated motor control directly resolves the time loss issue while maintaining ease of operation.
3Adaptability or versatility
If fixed seat position is used, then the device complexity is reduced, but the rider cannot maintain optimal position on varying terrain
Solution Approach 1:
The motorized seat post assembly serves multiple functions: it controls both seat height adjustment and seat tilt adjustment through integrated motor assemblies. This multi-functionality allows the system to adapt to varying terrain conditions while consolidating the complexity into a single universal adjustment mechanism rather than separate systems for height and tilt.
Solution Approach 2:
The system transitions from a fixed seat position to a dynamic, adjustable position system. The motorized assemblies enable real-time modification of seat height and tilt angles, allowing the bicycle to adapt dynamically to changing terrain conditions. This dynamic capability provides versatility while the integrated control system manages the complexity through unified operation.

AI summary
There is described a device for adjusting a seat position of a bicycle seat. The device allows a rider of a bicycle to adjust the tilt of their bicycle seat while the bicycle is in motion, without the rider having to first dismount. In some embodiments, the rider may also adjust the height of their bicycle seat at substantially the same time as the seat's tilt is adjusted, again without the rider having to first dismount. There are described a motorized embodiment in which one or more motors are used to drive a tilt actuator and a linear actuator, and a mechanized embodiment in which a source of pressurized air may be used to drive the linear actuator which in turn drives the tilt actuator.
