Linkage Clamping Structure for Fast, Even Force Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping devices either provide quick assembly but with insufficient clamping force or strong clamping force but at the cost of slow assembly and uneven force distribution.
Innovation Solution
A clamping device comprising a first and second clamping member, connecting rods, and an elastic member, where the elastic member provides a restoring force to rotate the connecting rods, allowing for quick assembly and adjustable clamping force by changing the spring coefficient of the elastic member, and even force distribution through strategically placed connecting rods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If elastic pieces are used for attachment, then quick clamping can be implemented, but the clamping force is relatively small and the clamping force is relatively uneven
Solution Approach 1:
The clamp body is divided into first and second clamping members connected by connecting rods, allowing independent movement and force distribution. This segmentation enables the elastic member to provide restoring force to multiple clamping points simultaneously, increasing overall clamping force while maintaining quick operation
Solution Approach 2:
The patent combines the quick-release mechanism of elastic pieces with the force distribution capability of multiple connecting rods. The elastic member works together with the segmented clamping members to achieve both quick clamping and enhanced clamping force through coordinated action of multiple components
2Force
If screws are used for attachment, then the clamping force is relatively great and the object can be tightly clamped, but clamping and disassembling cannot be completed quickly
Solution Approach 1:
The elastic member provides automatic restoring force to the connecting rods, enabling the clamping members to return to the clamped position without manual intervention. This self-service mechanism eliminates the need for screws while maintaining tight clamping, allowing quick disassembly by simply releasing the clamping members
3Stability of the object's composition
If multiple screws are used for attachment, then the clamping force can be evenly spread, but the device complexity increases and assembly becomes troublesome
Solution Approach 1:
The patent replaces the screw-based mechanical fastening system with an elastic restoring force system. The elastic member connected to connecting rods automatically distributes force evenly across multiple clamping members through its restoring characteristic, achieving stable force distribution without the complexity of multiple screws and their associated assembly procedures
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
Enables quick and secure clamping with adjustable force, facilitating easy assembly and disassembly, and ensuring even force application on the object.
Implementation Method 1
One end of the elastic member is connected to the third side, and the other end is connected to the first connecting rod. The elastic member provides a restoring force to make the first connecting rod rotate relative to the second clamping member

AI summary
A clamping device includes a first, a second clamping member, a first, a second connecting rod, and an elastic member. The first clamping member includes a first side and a second side opposite to each other. The second clamping member includes a third side and a fourth side opposite to each other. The first connecting rod is pivotally disposed between the first side and the third side. The second connecting rod is pivotally disposed between the second side and the fourth side. The elastic member is connected between the third side and the first connecting rod. The elastic member provides a restoring force to make the first connecting rod rotate relative to the second clamping member, to drive the second connecting rod and the first clamping member to rotate, so that a distance between the first and the second clamping member is shortened to clamp an object.
