Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional clamping tool is used for large-sized pipes, then the tool can perform basic clamping function, but it requires significant manual effort and time, reducing construction efficiency
Solution Approach 1:
The clamp handle angle adjustment mechanism allows the clamp handle angle to be dynamically changed during operation. The slider component moves along the guide pin shaft to adjust the angle between the clamp handle and the working head, enabling the tool to adapt to different pipe sizes and installation positions, thereby reducing manual effort and improving construction efficiency
Solution Approach 2:
The invention changes the geometric parameter of the clamp handle angle to optimize performance. By adjusting the angle between the clamp handle and the working head through the slider and guide pin shaft mechanism, the tool can achieve better mechanical advantage and reduce the manual effort required for clamping large-sized pipes
2Ease of operation
If the clamp handle angle is fixed, then the structure is simple, but it causes hand collisions and reduces operation flexibility during clamping
Solution Approach 1:
The clamp handle angle adjustment mechanism transforms the fixed angle structure into a dynamic adjustable one. The slider component can move along the guide pin shaft to change the angle between the clamp handle and the working head, preventing hand collisions and improving operation flexibility while maintaining reasonable structural complexity
Solution Approach 2:
The adjustment mechanism is segmented into independent components: the slider, the guide pin shaft, the positioning pin shaft, and the compression spring. This segmentation allows each component to perform its specific function independently, making the overall structure manageable and not overly complex while achieving the desired operational flexibility
3Productivity
If a clamping tool for small-sized pipes is used, then the tool structure is compact, but it is labor-intensive and time-consuming for large-sized pipes
Solution Approach 1:
The dynamic angle adjustment mechanism enables the tool to adapt to different pipe sizes by changing the clamp handle angle. For large-sized pipes, the angle can be adjusted to optimize the leverage and clamping force, thereby reducing installation time and improving productivity without sacrificing pipe size adaptability

AI summary
A clamping tool capable of changing a clamp handle angle comprises a working head (1), a clamp handle (2) and an adjustment structure (3). The working head (1) is formed by connecting a clamp head (1-1) and a positioning shaft (1-3) through a cover plate (1-2), a replaceable opening mould (1-4) is installed on the clamp head (1-1), the clamp handle (2) comprises a left clamp handle (2-1) and a right clamp handle (2-2), a ratchet retaining mechanism (4) is installed on the clamp handle (2), and the ratched retain-ing mechanism (4) comprises: a ratchet plate (4-2) installed at an upper clamp handle (2-2a) of the right clamp handle (2-2) and a ratchet (4-1) installed on the left clamp handle (2-1); the right clamp handle (2-2) comprises the upper clamp handle (2-2a) and a lower clamp handle (2-2b) movably connected to the upper clamp handle (2-2a) through a rotating shaft (6), and a clamp handle angle adjustment mechanism (5) is installed on the right clamp handle (2-2). When the clamping tool works, the clamp handle angle can be changed easily only by pulling the handle, so that the clamping operation is very laborsaving and the efficiency of installation operations is enhanced. Also, the clamp handle (2) is designed with a certain angle, and through the clamp handle angle adjustment mechanism (5), the phenomenon of touch of two hands during work is prevented.
