Climbing Machine Single Circulating Transmission Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing climbing machines with timing belts and pinch pulleys require multiple components, leading to complexity and inefficiency in the transmission path, which can cause rubbing issues and hinder the natural movement of hands and feet during exercise.
Innovation Solution
A climbing machine with a single circulating transmission path structure, utilizing a rolling assembly and transmission assembly with rollers and transmission members to connect pedal and handle sliders, eliminating the need for additional timing belts and simplifying the component count, while allowing for adjustable resistance and improved user movement synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If timing belt and pinch pulleys are used to connect connecting frames, then the transmission path is established, but the number of components increases and the structure becomes complex
Solution Approach 1:
The patent merges the transmission functions of multiple separate belts into a single circulating transmission path that connects all four sliders (first pedal slider, second pedal slider, first handle slider, second handle slider) through one continuous transmission path, eliminating the need for separate timing belts and pinch pulleys on each side
Solution Approach 2:
The single circulating transmission path serves multiple functions simultaneously: it connects the pedal sliders, connects the handle sliders, and transmits force between all components, making the transmission system multi-functional rather than requiring separate dedicated transmission paths for each function
2Reliability
If connecting frames are disposed on both sides of the frame with separate timing belts, then the transmission function is achieved, but the machine height increases
Solution Approach 1:
The patent reconfigures the transmission path to circulate in a compact loop that utilizes vertical and horizontal space more efficiently, allowing the transmission path to connect components at different heights without requiring the machine frame itself to be taller
3Reliability
If multiple timing belts and connecting belts are used, then the transmission path is established, but the smoothness of movement is reduced due to rubbing and component friction
Solution Approach 1:
By combining multiple separate belt transmissions into one continuous circulating transmission path, the patent eliminates the rubbing and friction that occur where multiple belts and pulleys interact, allowing for smoother movement of the sliders along their guide rails

AI summary
A climbing machine having a single circulating transmission path structure is disclosed. The climbing machine includes a frame body, a first slide rail assembly, a second slide rail assembly, and a transmission unit. A transmission assembly of the transmission unit is continuously connected with a first pedal slider, a second pedal slider, a first handle slider, a second handle slider to form a single circulating transmission path instead of two independent paths on both sides of the frame body. The smoothness of the transmission path can be improved without the need for timing belts or connecting belts.
