Treadmill Folding Mechanism With Locking Dial Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing folding treadmills have a display device bracket that cannot be folded, occupying storage space when the treadmill is stored, thus affecting storage efficiency.
Innovation Solution
A folding mechanism for a treadmill featuring a standpipe with a hinge and limiting hole, a dial frame with a movable limiting member and elastic member, allowing the dial frame to transition between locked and unlocked positions for use and storage, and a standpipe that rotates relative to the base for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bracket for mounting the display device is fixed to the body, then the bracket is stable during use, but the bracket cannot be folded when the treadmill is stored, occupying storage space
Solution Approach 1:
The bracket is designed with a dial frame that can rotate relative to the standpipe between a first position (for use) and a second position (for storage). This dynamic structure allows the bracket to transition from a fixed stable state to a folded compact state, resolving the contradiction between stability during use and space efficiency during storage
Solution Approach 2:
The bracket is divided into separable components: the standpipe with connection portion, the dial frame with body, hinge portions, and limiting members. This segmentation allows the dial frame to be independently rotated and folded relative to the standpipe, enabling the bracket to reduce storage space while maintaining structural integrity
2Volume of moving object
If the dial frame is made foldable, then the storage space is reduced, but the structure becomes more complex with additional components
Solution Approach 1:
The limiting member is received within the limiting hole of the connection portion when the dial frame is folded, creating a nested configuration. The hinge portion is pivotally connected within the hinge hole, and the limiting member can be movably received through the limiting hole,实现ing a compact nested structure that reduces complexity while enabling folding functionality
Solution Approach 2:
The first elastic member automatically pushes the limiting member to maintain engagement with the limiting hole, providing self-locking functionality without requiring additional actuators or complex control mechanisms. The elastic member ensures the limiting member remains in the locked position during use and can be easily disengaged when folding is needed
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
Improves stability during use and convenience during storage by allowing the display device to be folded and the treadmill to occupy minimal space when not in use.
Implementation Method 1
The first elastic member is always in a compression state and applies an elastic force to the second anti-disengagement portion, such that the limiting member is always in the locking position
