Solution Overview
Problem
Conventional climbing machines have limited ergonomic design with straight moving paths for handles and pedals, resulting in long response times and non-smooth operations due to belt or steel rope mechanisms.
Innovation Solution
The climbing machine features a frame with rock arms, cranks, sliding rods, and adjustable climbing assemblies with inner and outer tubes, allowing for more realistic movements and reduced friction, enabling alternate up and down motions driven by cranks and resistance devices for smooth and quick operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional climbing machines use straight line moving paths for handles and pedals, then the structure is simple, but the operation is less ergonomic and response time is long
Solution Approach 1:
The patent replaces the conventional straight line moving paths with curved moving paths for both handles and pedals. The curved trajectory better mimics natural climbing motion and human body mechanics, improving ergonomics. The curvature allows for smoother transitions and faster response times by eliminating the rigidity of straight-line constraints.
Solution Approach 2:
The patent introduces dynamic adjustment capabilities where the moving paths of handles and pedals can be adjusted to different curved trajectories. This dynamic configuration allows users to customize the exercise intensity and motion pattern, enhancing ergonomic adaptability while reducing response time through optimized path geometry.
2Ease of operation
If conventional climbing machines use belt or steel rope to pull holders up and down, then the mechanism is simple, but the operation is non-smooth and response time is long
Solution Approach 1:
The patent extracts and eliminates the belt or steel rope transmission mechanism from the system. By removing this intermediate transmission element, the direct connection between the driving mechanism and the holders is achieved, eliminating the delays and non-smooth operations caused by belt slippage or rope elasticity.
Solution Approach 2:
The patent replaces the belt/rope mechanical transmission system with a direct mechanical linkage system. This substitution provides more precise control, faster response time, and smoother operation by eliminating the flexible intermediate elements that cause operational delays and irregularities.
3Ease of operation
If conventional climbing machines have limited moving paths constrained by rail or track structure, then the structure is stable, but the ergonomic design is limited
Solution Approach 1:
The patent employs curved guiding structures instead of conventional straight rails or tracks. These curved guides provide stable support while enabling more natural and ergonomic climbing motions. The curved geometry allows for better alignment with human body mechanics without significantly increasing structural complexity.
Solution Approach 2:
The patent designs the guiding structure to serve multiple functions: providing structural stability, enabling ergonomic curved motion paths, and allowing for adjustable trajectories. This multi-functional design achieves ergonomic improvement without proportionally increasing device complexity.
