Oblong Orbital Exerciser Roller Track Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oblong orbital exercising machines experience roller deflection and detachment from guiding tracks at higher speeds, leading to instability and vibration during use.
Innovation Solution
The design incorporates driven bars directly connected to swinging handles, rollers pivotally connected to driven bars, and guiding tracks arranged centrally, with pedal units featuring fixing plates, rocking plates, springs, and fastening rods to ensure smooth, stable movement and ergonomic positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If rollers are moved on guiding tracks at higher speed, then exercise intensity is improved, but rollers are easily deflected and detached from guiding tracks
Solution Approach 1:
The roller is nested within the guiding track structure, with the roller positioned inside a recessed area of the track. This nesting arrangement ensures the roller remains confined to the track path even at higher speeds, preventing detachment while allowing improved movement speed for enhanced exercise intensity.
2Stability of the object's composition
If driven bars are connected to swinging handles, then movement smoothness is improved, but device complexity increases
Solution Approach 1:
The driven bar is merged with the swinging handle assembly through a direct pivotal connection. This combining of components creates a unified movement system where the driven bar follows the natural arc of the swinging handle, achieving smooth stable movement without requiring complex intermediate connection mechanisms.
3Object-affected harmful factors
If guiding tracks are arranged centrally on main frame, then operational safety is improved, but manufacturing complexity increases
Solution Approach 1:
The guiding track system is segmented into separate components that can be independently manufactured and then assembled onto the main frame in a centralized position. This segmentation allows the main frame to be manufactured with standard features while the guiding tracks are separately fabricated and positioned centrally during assembly, improving safety without significantly increasing overall manufacturing complexity.
