Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stationary bikes lack the ability to adjust the left and right oscillation width and rotation of the saddle, which limits flexibility and stability for users, particularly those with spinal issues, and fails to effectively engage core muscles during exercise.
Innovation Solution
A left and right oscillation width adjustment and rotation structure for a stationary bike saddle, featuring a buffering part, left and right moving parts, forward and backward moving parts, and an eccentric rotating part, which allows for adjustable oscillation width and rotation radius to accommodate individual body types and hip joint motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the saddle is fixed in position, then the structure is simple and stable, but the user cannot adjust according to hip joint range of motion and spine flexibility
Solution Approach 1:
The saddle is transformed from a fixed structure to a dynamic one with multiple degrees of freedom. The first moving part enables left-right oscillation, the second moving part enables forward-backward movement, and the rotating part enables rotational adjustment. This dynamic structure allows the saddle to adapt to different user body types and hip joint ranges of motion while maintaining operational simplicity through gravity-based automatic positioning.
2Adaptability or versatility
If the saddle allows free motion, then user flexibility is improved, but stability during pedaling deteriorates
Solution Approach 1:
The saddle system controls motion parameters through gravity and mechanical constraints. The first moving part oscillates within a controlled angular range, the second moving part moves forward and backward within limited travel, and the rotating part rotates to a stable equilibrium position. These parameter changes enable flexible motion for core muscle engagement while maintaining stability during pedaling through gravity-based positioning and mechanical guidance.
3Adaptability or versatility
If the saddle oscillation width is fixed, then manufacturing is simple, but it cannot accommodate different user body types
Solution Approach 1:
The oscillation width is made dynamically adjustable through the first moving part that can oscillate left and right relative to the saddle. This mechanical degree of freedom allows users with different body types and hip joint ranges of motion to naturally find their comfortable oscillation amplitude during exercise, eliminating the need for multiple fixed-width saddle models while maintaining simple manufacturing of the base structure.
4Adaptability or versatility
If the saddle is stationary, then spinal burden is reduced, but core muscle training opportunity is lost
Solution Approach 1:
The saddle introduces controlled dynamic motion with three degrees of freedom: left-right oscillation via the first moving part, forward-backward movement via the second moving part, and rotation via the rotating part. This dynamic design engages core muscles to stabilize the pelvis and control saddle motion while the gravity-based buffering mechanism reduces spinal burden by absorbing oscillations and providing passive support, achieving both core training and spinal protection simultaneously.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances stability and flexibility during pedaling by buffering left and right oscillations and dispersing load, while also enabling core muscle training through adjustable saddle motion, thus improving overall exercise efficacy and reducing spinal burden.
Implementation Method 1
a buffering part (100) which is disposed on a bottom surface of the saddle member (8) to relieve left and right oscillations and a load dispersed by a pedaling operation of the user
Implementation Method 2
a coil part (120) which is composed of a pair and coupled to both sides of a bottom surface of the buffering plate to induce a buffering action of the left and right oscillations of the saddle and the dispersed load

AI summary
The present invention relates to a right and left oscillation width adjustment and rotation structure of a stationary bike saddle, which enables a user to directly perform adjustment to correspond to the range of motion of the hip joint while inducing the buffering action of the left and right oscillations of the saddle and the dispersed load when the user sits on the saddle of the stationary bike and pedals thereon, so as to secure stability for the motion of the pelvis and spine during pedaling and enables core muscle training at the same time as lower body exercise during pedaling, the structure consisting of: a buffering part (100) which is disposed on the bottom surface of a saddle member (8) to relieve the load and left and right oscillations dispersed by the user's pedaling operation; a left and right moving part (200) which is coupled to the buffering part to perform a left and right sliding motion; a forward and backward moving part (300) which is coupled to the left and right moving part (200) to perform a forward and backward sliding motion; and an eccentric rotating part (400), in which the left and right moving part (200) and the forward and backward moving part (300) are coupled and which is rotated eccentrically to simultaneously control the sliding motion of each moving part. The eccentric rotation radius of the eccentric rotation part (400) can be extended or reduced according to the user's selection, and the left and right sliding and forward and backward sliding motions are controlled by the adjusted rotation radius.
