Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle fitting devices are static, preventing cyclists from adjusting their seat and handlebar positions in real-time while riding, which can lead to discomfort, inefficiency, and potential injuries.
Innovation Solution
A motorized seat post and stem fit system that includes a drive assembly with actuators and motors, allowing for vertical and horizontal adjustments of the seat and handlebars, controlled by a user interface that collects and modifies x and y coordinates in real-time, enabling on-the-fly adjustments during cycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If static fitting devices are used to determine optimal seat and handlebar positions, then measurement precision can be achieved, but the cyclist cannot experience real-time adjustments on their actual bicycle
Solution Approach 1:
The patent transforms static fitting devices into dynamic systems by incorporating motorized actuators that enable real-time adjustment of seat and handlebar positions. The drive assembly with motors and actuators allows the fitting device to dynamically modify positions while the cyclist rides, bridging the gap between precise measurement and real-time adaptability.
Solution Approach 2:
The patent replaces manual mechanical adjustment mechanisms with motorized drive assemblies. The motors and actuators provide automated, precise control over position adjustments, eliminating the need for manual tools and protocols while enabling real-time changes during cycling.
2Device complexity
If manual fitting protocols are used, then device complexity remains low, but the cyclist must transfer obtained positions to their actual bike, losing real-time experience
Solution Approach 1:
The fitting device performs self-service by automatically adjusting seat and handlebar positions during cycling. The motorized actuators enable the system to modify positions without requiring the cyclist to manually intervene or transfer adjustments, making the process as easy as riding while providing real-time feedback.
3Adaptability or versatility
If the fitting device allows position adjustments during riding, then adaptability improves, but the device complexity increases due to motors and actuators
Solution Approach 1:
The patent segments the fitting device into distinct functional modules: a drive assembly with motors, actuators for horizontal and vertical adjustments, and a controller. This modular segmentation allows each component to perform its specific function while maintaining overall system manageability and reducing complexity through specialization.
Solution Approach 2:
The drive assembly serves multiple functions through its motorized actuators, providing both horizontal and vertical position adjustments, as well as potentially controlling stem angle and other bicycle components. This multi-functionality reduces the need for separate adjustment mechanisms, thereby managing complexity while enhancing adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables cyclists to make real-time adjustments to their seat and handlebar positions while riding, enhancing comfort, efficiency, and safety by allowing for dynamic fitting on the road, rather than relying on static pre-adjustments.
Implementation Method 1
the actuator being horizontally displaceable between a non-elongated position and an elongated position; wherein when the actuator horizontally moves between its non-elongated position and its elongated position, the sliding element horizontally moves with the actuator, thereby horizontally displacing the seat
Implementation Method 2
a worm drive driven by the motor for controlling the scissor element and vertically displacing the seat relative to the seat post
Implementation Method 3
a scissor element pivotally mounted at least partially above the seat post mounting element; wherein when the worm drive horizontally moves, at least a portion of the scissor element moves between its non-elongated position and an elongated position, thereby vertically displacing the seat

AI summary
A seat and motorized stem fit device is designed for fitting a cyclist on a bicycle having a seat post and a seat, with the seat post being an original seat post provided by a seat post manufacturer. The motorized seat post fit device comprises a drive assembly and an adjustable seat assembly coupled to the drive assembly and providing an interface between the seat post and the seat. The drive assembly controls the adjustable seat assembly to provide at least one of a vertical displacement and a horizontal displacement of the seat relative to the seat post.
