Clamping device and mobile terminal holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted fixed holders require high precision in processing external or internal threads on the moving plate, leading to increased machining difficulty and reduced structural strength, while exposed threads affect the aesthetic appeal.
Innovation Solution
A clamping device with a rotating part, screw, and nut configuration, where the screw is mounted within the rotating part, and the first clamping part is connected to the nut, allowing for movement along the screw's axis, eliminating the need for exposed threads and simplifying processing by using standard parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external or internal threads are arranged on the moving plate to match with the housing or screw, then the moving plate can be moved when the housing is rotated, but the processing precision requirement is high and machining difficulty increases
Solution Approach 1:
The patent divides the threaded connection system into separate components: the housing contains the screw while the moving plate contains the nut. This segmentation allows each component to be manufactured independently with standard threading, eliminating the need for high-precision matched threading between the housing and moving plate.
Solution Approach 2:
The patent introduces a nut as an intermediary component between the screw (in the housing) and the moving plate. This intermediary allows the moving plate to be driven by the rotating screw without requiring direct threaded engagement between the housing and moving plate, thereby reducing machining difficulty.
2Ease of operation
If external or internal threads are arranged on the moving plate, then the clamping mechanism can function, but the structural strength of the moving plate is reduced
Solution Approach 1:
By separating the threaded features into different components (screw in housing, nut in moving plate), the patent avoids weakening the moving plate with external threads or complex internal threading, thereby preserving its structural strength.
3Ease of manufacture
If threads are exposed on the clamping mechanism, then the threading function is achieved, but the aesthetic appeal is affected
Solution Approach 1:
The patent nests the screw within the housing and the nut within the moving plate, concealing the threaded components inside the respective bodies. This nested arrangement achieves the threading function while maintaining a clean, aesthetic external appearance without exposed threads.
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 solution enhances structural strength and reduces processing complexity, while eliminating the issue of exposed threads, resulting in a more aesthetically pleasing and robust clamping mechanism.
Implementation Method 1
a nut, wherein the nut is in threaded connection with the screw; a first clamping part, wherein one end of the first clamping part is arranged in the rotating part and is connected to the nut

AI summary
A clamping device and a mobile terminal holder are provided. The clamping device comprising a rotating part, a screw mounted in the rotating part, a nut in threaded connection with the screw, a first and a second clamping parts. One end of the first clamping part is arranged in the rotating part and is connected to the nut, and the other end extends out of the rotating part. The rotating part is sleeved on the second clamping part in a rotatable manner. In use, the rotating part is rotated to drive the screw to rotate, such that the nut moves along the axial direction of the screw, which in turn drives the first clamping part to move along the axial direction of the screw, such that the first clamping part is close to or far away from the second clamping part.
