Elliptical Bike Platform Angle Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elliptical bicycles lack the ability to adjust the angle of the platforms, limiting the variety of muscle groups that can be worked during use.
Innovation Solution
The integration of rear pulleys that are screwed into welded protrusions on the frame with holes, allowing the platforms to be raised and lowered to different angles, providing options for engaging different muscle groups in the legs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the platforms are fixed at a single angle on existing elliptical bicycles, then the structure is simple and stable, but the ability to target different muscle groups is limited
Solution Approach 1:
The platform angle adjustment mechanism transforms the static platform into a dynamic component that can change its orientation. The platform is no longer fixed at a single angle but can be adjusted to multiple angles, allowing the exercise equipment to adapt to different workout requirements and target different muscle groups effectively.
Solution Approach 2:
The invention changes the angular parameter of the platform by providing multiple predetermined angles through the adjustment mechanism. This parameter change enables users to vary the exercise intensity and target different muscle groups by selecting different platform angles, thereby improving versatility without significantly complicating the overall structure.
2Adaptability or versatility
If multiple platform angles are provided, then muscle workout variety is improved, but the structural complexity increases
Solution Approach 1:
The adjustment mechanism is segmented into discrete components including the rear pulley, frame members, and platform. This segmentation allows each component to perform its specific function independently while working together to achieve the angle adjustment capability, managing structural complexity through modular design.
Solution Approach 2:
The rear pulley and frame structure serve multiple functions: they support the platform, enable angle adjustment, and provide structural stability. This multi-functionality reduces the need for additional separate components, thereby achieving angle variation capability without proportionally increasing overall structural complexity.
3Productivity
If the platform angle is adjustable, then workout effectiveness is enhanced, but the mechanism complexity increases
Solution Approach 1:
The platform angle adjustment mechanism is designed to be user-operable without requiring external assistance or complex control systems. Users can independently adjust the platform angle to suit their workout preferences, making the system self-service and avoiding the need for additional complex control mechanisms that would further increase device complexity.

AI summary
An elliptical bike is described having a function that elliptical bikes of the related art do not have, since their rear pulleys, which support the platforms, are screwed into protrusions welded to the frame, which have holes. The bicycle also comprises a folding embodiment, and holes that are suitable for raising and lowering the angle of attack of the platforms and the positioning of the rear pulleys, which are fixed (e.g., screwed) into protrusions welded to the frame, thereby providing four positions of angle of attack, giving the option to work different muscles in the user’s legs.
