Solution Overview
Problem
Existing guide frame support devices require manual, precise adjustment of separation distance between the guide frame and pipe, which is prone to errors and lacks sufficient elasticity, especially when pipe diameters change, leading to potential damage or inefficient welding processes.
Innovation Solution
A guide frame support device featuring a hinge bar, rotating support bars, torsion springs, a cam plate, and a stopper bolt, allowing for adjustable separation distance and elasticity, enabling precise and efficient positioning of the guide frame relative to the pipe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of separation distance is performed, then the guide frame support device can be installed, but adjustment precision deteriorates and errors occur
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automatic control system that uses sensors to detect the actual separation distance and a control unit to calculate and command adjustments, thereby eliminating human error in measurement and adjustment precision
Solution Approach 2:
The patent implements a feedback mechanism where sensors continuously monitor the separation distance between the guide frame and pipe, feed this information back to the control unit, which then automatically adjusts the support device to maintain the correct distance, eliminating manual adjustment errors
2Device complexity
If the elastic limit of double plate-spring is weak, then the structure is simple, but the bearing power is insufficient and many support devices must be attached
Solution Approach 1:
The patent changes the elastic parameter by replacing the double plate-spring with a torsion spring that has a higher elastic limit and stronger bearing capacity, allowing fewer support devices to be used while maintaining sufficient force
Solution Approach 2:
The patent employs a composite structure combining the torsion spring with the guide frame and support bars, creating a system that maximizes bearing power while maintaining structural simplicity
3Adaptability or versatility
If insert type plates are used to adjust separation distance, then the separation distance can be modified, but the procedure becomes complex and time-consuming
Solution Approach 1:
The patent implements a dynamic adjustment mechanism where the torsion spring allows continuous and smooth adjustment of the separation distance by rotating the support bars, eliminating the need for discrete insert type plates and complex assembly procedures
Solution Approach 2:
The torsion spring serves multiple functions: it provides elastic force, enables adjustable separation distance, and allows adaptation to different pipe diameters, replacing the need for multiple insert type plates and simplifying the overall adjustment procedure
