Elliptical Exercise Machine Pivot Joint Folding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elliptical exercise machines occupy a large amount of horizontal space due to their bulky drive assembly and components, making it difficult to fold them into a compact configuration that reduces both vertical and horizontal space usage.
Innovation Solution
An elliptical exercise machine with a centrally located pivot joint in the base support structure that allows the machine to fold into an upright compact configuration, featuring a breakaway base support and upward rotation of the rear portion with respect to the front portion, enabling the machine to be stored in a more compact and space-efficient manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the elliptical exercise machine uses a bulky drive assembly and traditional support structure, then the machine provides sufficient structural strength and operational stability, but it occupies a large amount of horizontal space and cannot be folded into a compact configuration
Solution Approach 1:
The base support structure is divided into a front portion and a rear portion that can pivot relative to each other about a pivot joint. This segmentation allows the rear portion to be folded upward onto the front portion, reducing the horizontal footprint while maintaining structural integrity during operation.
Solution Approach 2:
The base support structure transitions from a static, fixed configuration to a dynamic, movable configuration through the pivot joint. The structure can dynamically switch between an operational state (horizontal configuration for exercise) and a folded state (upright configuration for storage), adapting to different usage requirements.
2Adaptability or versatility
If the elliptical exercise machine uses a traditional fixed base support structure, then the machine maintains stable operation during exercise, but it requires a large amount of space for both operation and storage
Solution Approach 1:
The base support structure incorporates a pivot joint that enables dynamic reconfiguration between operational and folded states. This dynamic capability allows the machine to adapt to different space requirements, providing versatility for both exercise and storage scenarios.
Solution Approach 2:
The folding mechanism utilizes the vertical dimension by rotating the rear portion upward onto the front portion. This dimensional transition converts a horizontally extended structure into a vertically compact configuration, effectively reducing the horizontal footprint while maintaining structural integrity.
3Area of stationary object
If the elliptical exercise machine is designed for residential use with space constraints, then it can be stored in tighter spaces, but the drive assembly and support structure must be redesigned to enable compact folding
Solution Approach 1:
The base support structure is segmented into front and rear portions connected by a pivot joint, allowing independent movement of each section. This segmentation enables the rear portion to fold upward without requiring complete disassembly or complex mechanisms, balancing compactness with structural simplicity.
Solution Approach 2:
The pivot joint serves multiple functions: it provides structural support during operation, enables folding for compact storage, and maintains stability in both configurations. This multi-functionality reduces the need for additional components, keeping the overall device complexity manageable.
