Exercise Rod Rotating Support Member Eliminates Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise rods suffer from damage due to stress on hinges, inability to adapt to users of different stature, and generate noise from metal components during use.
Innovation Solution
An exercise rod design featuring a rotatably sleeved supporting member with an annular positioning groove, a hook for connecting the exercise elastic rope, and a blocking mechanism to prevent separation, along with a tubular structure and anti-separation components to reduce noise and enhance user adjustability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the exercise elastic rope is connected through metal hanging rings and U-shaped rope lugs, then the connection is strong and reliable, but loud noise is generated when the components collide or friction against each other
Solution Approach 1:
The patent replaces expensive and noisy metal components with a disposable plastic buckle that can be easily replaced. The plastic material eliminates noise while maintaining sufficient connection reliability for exercise purposes.
Solution Approach 2:
The patent changes the material parameter from metal to plastic, fundamentally altering the acoustic properties while maintaining the mechanical function. The plastic material provides noise-free operation while the buckle design ensures reliable connection.
2Ease of manufacture
If the force pedal position is fixed, then the structure is simple and easy to manufacture, but it cannot adapt to users of different stature
Solution Approach 1:
The patent transitions from a fixed force pedal position to an adjustable position system. Users can move the force pedal along the rod to different locations, allowing adaptation to various user statures while maintaining a simple rod structure without complex mechanisms.
Solution Approach 2:
The rod serves multiple functions: it acts as both a support structure and an adjustable positioning system. The same rod structure accommodates different user heights by allowing the force pedal to be positioned at different locations along its length.
3Adaptability or versatility
If the first main body shell and second main body shell are folded and connected through a hinge, then the device is portable and easy to store, but the hinge承受s excessive stress and can easily damage or separate
Solution Approach 1:
Instead of folding the main body shells at the hinge, the patent inverts the approach by keeping the rod straight and rigid while allowing the exercise elastic rope to provide the necessary flexibility and movement. The hinge is no longer the primary folding mechanism, reducing its stress burden.
Solution Approach 2:
The exercise elastic rope acts as an intermediary element that absorbs stress and provides flexibility, replacing the need for the hinge to bear folding stresses. The rope's elastic properties allow the system to remain portable while protecting the hinge from damage.
Applied Scientific Principles

Function Achieved in This Case
The design eliminates noise and stress on hinges, allows for adjustable exercise positions, and provides a stable pull system for various exercises, including pull, push, and squat exercises, while maintaining low production costs.
Implementation Method 1
the supporting member is rotatably sleeved on both ends of the exercise rod, respectively
Implementation Method 2
exercise elastic rope

AI summary
An exercise rod for supporting an exercise elastic rope includes a supporting member rotatably sleeved on the exercise rod. The periphery of the supporting member is provided with an annular positioning groove for cooperating with a hook. An end of the exercise rod is detachably provided with a blocking member configured to prevent the supporting member from separation, a retractable blocking button is arranged adjacent to the end of the exercise rod, and the supporting member is limited between the blocking button and the blocking member. The supporting member is rotatably sleeved on the exercise rod, and the supporting member is provided with a positioning groove matched with the hook. When the hook is subjected to force, the relative movement between the hook and the supporting member is transformed into the rotation of the supporting member, thereby eliminating the sound caused by friction and collision between parts.
