Automatic Sheet Welding Chassis With Retractable Rollers for Edge Work
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic welding machines for thermally joining material sheets face challenges in handling and maintenance complexity, particularly when operating near edges or sloping surfaces, due to rigid axles and exposed elements that can lead to corrosion and increased susceptibility to damage.
Innovation Solution
The introduction of a telescopic pull-out mechanism allows the heating device and traveling rollers to be moved parallel to the transverse axis, enabling ergonomic retraction and protection from dirt and corrosion, reducing maintenance needs and improving handling safety by eliminating protruding rigid axles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid axles and exposed elements are used in the welding machine structure, then structural stability is improved, but maintenance complexity increases due to corrosion and damage susceptibility
Solution Approach 1:
The patent applies the dynamics principle by making the axle system movable rather than fixed. The telescopic pull-out mechanism allows the axle to be retracted into the housing when not in use, protecting it from corrosion and damage. This dynamic configuration maintains structural stability during operation while reducing maintenance complexity through protection during storage and transport.
Solution Approach 2:
The patent extracts the vulnerable axle element from its traditional fixed position and separates it from the main housing structure. By using a telescopic pull-out mechanism, the axle can be removed or retracted independently, allowing for easier maintenance and protection from environmental factors that cause corrosion and damage.
2Stability of the object's composition
If fixed support wheels are positioned far apart for stability, then lateral tipping is prevented, but welding close to edges is obstructed
Solution Approach 1:
The support wheels are made dynamically positionable through the telescopic pull-out mechanism. They can be extended outward when needed for stability during welding operations and retracted inward when edge welding is required. This dynamic adjustment allows the machine to adapt between different working conditions, maintaining both lateral stability and edge welding capability.
Solution Approach 2:
The telescopic pull-out mechanism provides multi-functionality to the support wheels. The same structural element serves dual purposes: providing lateral stability when extended and enabling edge welding when retracted. This universal design eliminates the need for separate configurations or additional components to handle different welding scenarios.
3Ease of repair
If telescopic pull-out mechanism is implemented, then maintenance requirements are reduced through protection from dirt and corrosion, but device complexity increases
Solution Approach 1:
The patent merges the telescopic pull-out mechanism with the existing axle and support wheel structures. Rather than adding completely separate systems, the telescopic functionality is integrated into the existing components, reducing overall device complexity while still providing the protective benefits that reduce maintenance requirements.
