Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mountain climbing machines suffer from poor stability when supported on the ground, leading to sliding during use.
Innovation Solution
A mountain climbing machine design featuring a support frame assembly with a first supporting frame and a second supporting frame that inclines upward, equipped with guiding members, pedal assemblies, and a locking assembly to stabilize the structure, along with a foldable armrest frame assembly for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the mountain climbing machine uses a herringbone shape with lower ends supported on the ground, then the structure is compact and space-saving, but the stability is poor and it slides during use
Solution Approach 1:
The support frame is divided into a first supporting frame (stable base) and a second supporting frame (inclined climbing section), with the first frame providing stable ground support while the second frame enables the climbing motion. This segmentation allows the stable support function and the climbing function to be separated, resolving the contradiction between compactness and stability.
Solution Approach 2:
The design transitions from a two-dimensional herringbone layout to a three-dimensional structure where the second supporting frame is inclined upward from the first supporting frame. This dimensional change allows the climbing motion to occur in a vertical plane while the base remains stable on the ground, eliminating sliding while maintaining space efficiency.
2Stability of the object's composition
If the mountain climbing machine is designed with a fixed structure for stability, then it is stable during use, but it occupies more space and is harder to store and transport
Solution Approach 1:
The connection between the first supporting frame and the second supporting frame is made detachable rather than fixed. The locking assembly allows the frames to be connected and locked together during use for stability, and disconnected or folded together for storage, transforming the structure from static to dynamic and resolving the contradiction between stability and storability.
Solution Approach 2:
The detachable locking assembly allows the user to discard the connected state during storage and recover it during use. The first and second supporting frames can be separated or folded together when not in use, reducing storage space, then reconnected and locked when needed to provide stable support during climbing exercise.
3Ease of operation
If the mountain climbing machine uses a detachable locking assembly for easy storage, then it is easy to assemble and disassemble, but it may reduce structural stability
Solution Approach 1:
The locking assembly is designed with locking grooves and locking pins that automatically engage when the first and second supporting frames are connected. This beforehand cushioning ensures that the structure is immediately stabilized upon assembly without requiring additional adjustment or tightening, maintaining structural stability while preserving ease of assembly and disassembly.
