Swingable Mechanical Structure for Fitness Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fitness machines, such as indoor bikes, primarily focus on leg exercises and fail to effectively engage the waist muscles, leading to monotony and inadequate workout results due to the lack of varied motion.
Innovation Solution
A swingable mechanical structure comprising a machine base, a swing mechanism with a rotating shaft, tilt member, and swing post, and an auxiliary bracket, which allows the seat to swing sideways when pedals are stepped, incorporating a rotating shaft and tilt member with adjustable angles to convert force input into a swinging motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional indoor fitness bike is operated by stepping motion on pedals only, then the exercise effect on legs is achieved, but the exercise effect on waist is insufficient and the exercise mode is monotonous
Solution Approach 1:
The patent applies the dynamics principle by introducing a swing mechanism that allows the seat to move dynamically between static and swinging states. The swing mechanism includes a swing arm connected to the seat, enabling the seat to perform swinging motion in addition to the traditional pedaling motion, thereby providing varied exercise modes without significantly complicating the overall structure
Solution Approach 2:
The patent implements multi-functionality by designing the swing mechanism to provide both static seating and dynamic swinging functions. The same mechanical structure serves multiple purposes: it allows users to choose between traditional pedaling exercise and swinging exercise, or combine both motions, thus increasing exercise mode variety while using a unified mechanical system
2Adaptability or versatility
If a swing mechanism is added to provide swinging motion, then the exercise effect on waist is improved and exercise mode variety is increased, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the swing mechanism into distinct modular components: a swing arm, a connecting rod, and a pivot connection point. This segmentation allows each component to perform its specific function independently while simplifying the overall assembly and maintenance, reducing the perceived complexity despite adding new functionality
Solution Approach 2:
The patent implements nesting by integrating the swing mechanism within the existing bike frame structure. The swing arm is positioned within the triangle formed by the frame, and the connecting rod nests within the swing arm's motion path, allowing the additional functionality to be accommodated within the existing spatial envelope without significantly increasing overall device complexity
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
Enhances the exercise experience by providing a more engaging and effective workout for the waist muscles through the introduction of a swinging motion, adding variety to the traditional pedaling exercise.
Implementation Method 1
form a mechanical structure with a force input and output conversion
Implementation Method 2
the tilt member is sheathed on the rotating shaft and intersected with the center line of the rotating shaft to define an angle, and such angle may be a fixed angle or a variable angle

AI summary
A swingable mechanical structure installed to fitness equipment or bicycles includes a machine base, a swing mechanism, and an auxiliary bracket. The swing mechanism includes a rotating shaft, a tilt member, and a swing post. The rotating shaft of the swing mechanism is installed into an assembling slot of the rotating shaft. Both ends of the auxiliary bracket are assembled to the machine base and an end of the swing post. When the rotating shaft is rotated, the rotating shaft is rotated to an angle with the respect to the tilt member, so that the swing post may swing together with the tilt member sideway and rotated around the tilt member. One of the ends of the swing post is limited by the auxiliary bracket, so that the swing post can just swing sideway to produce a mechanical structure with a force input and output conversion.
