Treadmill Armrest Handle Folding Mechanism for Easy Single-Side Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treadmills with fixed armrests are inconvenient for storage and require cumbersome operations for folding, while treadmills with folding armrests often have complex structures that are difficult for ordinary users to mount.
Innovation Solution
A folding mechanism for an armrest handle that allows folding through a single-sided operation using a connecting rod, limiting members, and an eccentric cam handle, with sliding grooves and limiting holes for easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed armrests are used, then structural simplicity is maintained, but storage convenience deteriorates
Solution Approach 1:
The armrest is designed with a folding mechanism that allows it to transition between extended and retracted positions. The connecting rod with limiting members and the rotation control plate with sliding grooves enable dynamic reconfiguration of the armrest structure, providing storage convenience while maintaining relative structural simplicity through a single-sided operation mechanism.
2Ease of operation
If two-sided folding operation is required, then folding function is achieved, but operational convenience deteriorates
Solution Approach 1:
The rotation control plate acts as an intermediary mechanism that translates a single-sided rotational input into coordinated movement of the connecting rod and limiting members. The sliding groove on the rotation control plate guides the limiting member's movement, enabling the folding function to be achieved through operation at only one side of the armrest, thereby improving operational convenience.
3Ease of operation
If complex folding armrest structure is implemented, then folding function is achieved, but ease of mounting deteriorates
Solution Approach 1:
The folding mechanism is segmented into distinct functional components: the connecting rod, the limiting members, the rotation control plate with sliding grooves, and the eccentric cam handle. This segmentation allows each component to be independently manufactured and assembled, simplifying the mounting process for ordinary purchasers while achieving the folding function through the coordinated action of these modular parts.
