Folding Treadmill Pin Lock Assembly Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding treadmills are inconvenient to operate due to their large size, requiring users to bend over to control folding buttons, leading to wear and safety hazards during transportation and folding, and lack stability in both unfolded and folded states.
Innovation Solution
A pin lock assembly with a switch handle, connecting rod, springs, pin members, and pin hole members allows for easy and secure unfolding and folding of the treadmill by locking the column assembly to the running platform, ensuring stability and safety in both states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual folding buttons are used on existing treadmills, then the treadmill can be folded, but the operation becomes inconvenient and complex requiring users to bend over and perform multiple movements
Solution Approach 1:
A folding handle is introduced as an intermediary component that users can easily grasp and operate. The handle is connected to the folding mechanism through a connecting rod, allowing users to control the folding process without bending over or performing complex movements. The handle serves as a mediator between the user's hand and the internal folding mechanism, simplifying the operation while maintaining the folding function.
2Ease of operation
If the folded column is left in a free state without locking, then folding is simpler, but wear occurs during transportation and safety hazards arise
Solution Approach 1:
The folding mechanism incorporates an automatic locking feature where the folding handle itself serves to lock the column in both folded and unfolded states. When the user pulls the handle, it engages with the connecting rod to lock the column in the folded position. When pushed back, it locks the column in the unfolded position. This self-locking mechanism eliminates the need for separate locking operations while ensuring stability and preventing wear during transportation.
3Volume of moving object
If the treadmill is designed to be foldable, then packing size is reduced, but the unfolded state may lack stability
Solution Approach 1:
The folding handle acts as a mediator that ensures stable locking in the unfolded state. When pushed back to its initial position, the handle engages the connecting rod to firmly lock the column assembly in the unfolded state, providing stability for use. The same handle mechanism that enables easy folding also ensures stable locking when unfolded, resolving the contradiction between foldability and stability.
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 pin lock assembly enables rapid and convenient unfolding and folding, maintaining stability and safety, and minimizes packing size by keeping the treadmill in a folded state during transportation, improving user experience and safety.
Implementation Method 1
at least two springs, wherein the pin members, the springs and the pin hole members are in a sleeving mode

AI summary
Disclosed are a folding treadmill and a folding method. A folding method of a folding treadmill includes the following steps: unlocking a pin lock assembly to enable a column assembly and a running platform to be in an unlocked free state, then unfolding or folding the column assembly to be in an unfolded state or a folded state relative to the running platform, and locking the pin lock assembly to complete the unfolding or folding of the treadmill. By means of the pin lock assembly, the column assembly can be firmly locked on the running platform no matter whether the column assembly is in the unfolded state or the folded state, thus not only achieving rapid unfolding and folding, but also ensuring the stability of the unfolded state or the folded state, and improving the safety of the folded state.
