Dual-Frame Exercise Bike with Movable Pull-Up Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stationary exercise bikes do not effectively engage multiple muscle groups simultaneously, limiting their ability to provide a comprehensive full-body workout and combining cardiovascular and strength training efficiently.
Innovation Solution
The exercise bike features a dual-frame design with a movable top section and pull-up bar, allowing users to adjust intensity and target heart rate, burn calories, and engage leg, back, and core muscles, along with incorporating handlebars and pedals connected to a flywheel for a comprehensive workout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional single-frame exercise bike design is used, then the structure is simple, but the ability to engage multiple muscle groups is limited
Solution Approach 1:
The frame is divided into two separate frames: a first frame supporting the flywheel and pedals, and a second frame supporting the pull-up bar. This segmentation allows each frame to serve specific functions, enabling engagement of multiple muscle groups (legs through pedaling, back and arms through pull-ups) while keeping individual frame structures relatively simple and manageable.
Solution Approach 2:
The exercise bike system is designed to perform multiple functions: cardiovascular exercise through pedaling and strength training through pull-ups. By integrating both functions into a single system with two frames, the device provides versatile full-body workout capabilities without requiring separate pieces of equipment.
2Adaptability or versatility
If a fixed frame design is used, then manufacturing is simpler, but user adaptability for different workout intensities is reduced
Solution Approach 1:
The top section of the second frame is designed to be selectively movable relative to the bottom section along an axis. This dynamic design allows users to adjust the position of the pull-up bar to modify workout intensity and target different muscle groups, while still maintaining a structured framework that is relatively straightforward to manufacture.
3Adaptability or versatility
If only leg muscles are targeted, then the exercise focus is simple, but the comprehensiveness of the workout is limited
Solution Approach 1:
The mechanical connection between the two frames is designed to be removable and modular. This segmentation allows the pull-up bar assembly to be easily attached and detached from the main frame, enabling comprehensive full-body workout capability while keeping the mechanical complexity manageable through standardized connection interfaces.
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
This design provides a superior full-body workout that targets multiple muscle groups, offering an effective combination of cardiovascular and strength training, enhancing calorie burn and metabolism, making it suitable for CrossFit training and cardiovascular exercises.
Implementation Method 1
The magnetic braking system may be magnets mounted on brackets selectively pivoted relative to the frame to increase or decrease the resistance opposing rotation of the flywheel
Implementation Method 2
a flywheel, also comprising pedals rotatably attached to the first frame and operatively connected to the flywheel

AI summary
An exercise bike machine includes a first frame having a front end and a rear end, and a second frame. The first frame supports a seat, handlebars, and a flywheel attached thereto, and pedals rotatably attached to the first frame and operatively connected to the flywheel. The seat includes a seat tube extending therefrom that is slidably received by a rear support tube supported by and connected to the first frame. The second frame includes a mechanical connection for removably engaging the first frame. The second frame includes a top section and a bottom section that are selectively movable relative one another along a vertical axis. The top section has a bar element allowing a user to hold onto and pull up to the bar element while peddling the flywheel, which may provide for both cardiovascular and CrossFit training and exercise for the user.
