Climbing Machine Alternating Linkage for Smooth Reciprocating Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing climbing machines require constant hand and feet to change the direction of movement when ascending or descending to an appropriate time, so that the user's hands and feet can naturally and smoothly perform a fixed-stroke reciprocating movement without deliberately controlling the return stroke, so that the user can exercise smoothly. The compact design allows for easy storage and transportation, and the user's feet are not affected by the user's feet and hands will not be impacted or blocked at the end of the ascending or descending stroke.
Innovation Solution
The climbing exercise machine features a frame with first and second lifting assemblies, an alternating mechanism, and a flywheel, allowing for fixed-stroke reciprocating movements of the user's hands and feet without requiring deliberate control changes at the end of the stroke, and a compact design for easy storage and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional climbing machine uses burring pads to stop the climbing device at the lowermost position, then the device can be stopped, but it causes impact on the exercise and requires user to constantly control direction changes
Solution Approach 1:
The patent uses a spring buffer to absorb impact energy before the climbing device reaches the burring pad. The spring buffer is positioned between the climbing device and the burring pad, providing cushioning that prevents direct impact while maintaining the stopping function.
Solution Approach 2:
The spring buffer acts as an intermediary element between the climbing device and the burring pad. It mediates the stopping process by gradually absorbing kinetic energy through compression, rather than allowing direct impact with the rigid burring pad.
2Length of moving object
If the climbing machine has a long overall height to provide sufficient motion stroke, then the exercise range is adequate, but it is not convenient for storage and transportation
Solution Approach 1:
The climbing machine is divided into an upper frame unit and a lower frame unit that can be separated from each other. This segmentation allows the machine to be disassembled into smaller components for easier storage and transportation, while maintaining the full motion stroke when assembled.
Solution Approach 2:
The patent transitions from a purely vertical height dimension to include horizontal stacking or side-by-side arrangement possibilities. By separating the frame units, the machine can be stored in a compact configuration that utilizes horizontal space rather than requiring excessive vertical clearance.
3Productivity
If the user constantly controls hands and feet to change direction at appropriate height, then the exercise can be performed, but the user's body becomes tense and movement is restrained
Solution Approach 1:
The spring buffer system provides automatic direction change assistance. When the climbing device reaches the lowermost position, the compressed spring buffer automatically propels the device upward, eliminating the need for the user to actively reverse direction. This self-service mechanism reduces user tension and allows more natural movement.
Solution Approach 2:
The spring buffer is pre-compressed during the downward movement and automatically exerts an upward force before the user needs to change direction. This preliminary anti-action counteracts the downward momentum and initiates the upward movement, reducing the effort and tension required from the user.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables smooth and continuous exercise with fixed-stroke reciprocation of the user's hands and feet to perform a fixed-stroke reciprocating movement without deliberate control changes, and the compact design facilitates easy storage and transportation.
Implementation Method 1
the rotational inertia will not drive the climbing devices to keep moving up or down. Therefore, the pedals and handles can be controlled by the user to change the direction of movement at any height

AI summary
A climbing exercise machine includes first and second lifting assemblies, each having a pedal and a handle. The two lifting assemblies can be moved up and down linearly and driven by each other through an alternating mechanism. The alternating mechanism has a rotating member, a first link rod and a second link rod. The rotating member has a first rotating portion and a second rotating portion. The first link rod connects the first rotating portion and the first lifting assembly, and the second link rod connects the second rotating portion and the second lifting assembly, so that up-down movements of the two lifting assemblies and rotation of the rotating member are driven by each other. Additionally, the rotating member is connected to a flywheel through a transmission mechanism and is driven by each other, and the inertia of the flywheel helps reciprocating movement of the pedal and the handle.
