Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional backing members are used to forcibly form multiple welds in a narrow space, then the welding quality can be ensured, but the installation process becomes cumbersome and complex
Solution Approach 1:
The backing member group structure is divided into multiple independent backing members (first backing members and second backing members) that can be separately installed and adjusted. Each backing member is a discrete unit with specific functions, allowing for modular installation in narrow spaces without requiring complex assembly of a single large component.
Solution Approach 2:
The distance between adjacent backing members is made adjustable through the elastic members and adjustment mechanisms. This dynamic adjustment capability allows the backing member group structure to adapt to different welding configurations and narrow space requirements, simplifying the installation process while maintaining welding quality.
2Manufacturing precision
If multiple backing members are installed sequentially in a narrow space, then forced forming of multiple welds can be achieved, but the installation time increases and efficiency decreases
Solution Approach 1:
The backing members are segmented into independent units that can be pre-assembled into a group structure. This segmentation allows for more efficient installation compared to sequentially installing individual backing members, as the group structure can be positioned as a unit while maintaining the ability to adjust individual member positions.
Solution Approach 2:
The backing member group structure is designed to handle multiple welds simultaneously with a single installation operation. The universal design allows the same structure to accommodate different welding configurations by adjusting the distance between members, thereby improving installation efficiency without sacrificing forced forming capability.
3Device complexity
If the distance between adjacent backing members is fixed, then the structure is simple, but it cannot adapt to different welding groove sizes and assembly requirements
Solution Approach 1:
The distance between adjacent backing members is made dynamic through elastic members that allow adjustment while maintaining structural integrity. This dynamic design enables the same backing member group structure to adapt to different welding groove sizes and assembly requirements without requiring multiple different structures, thus maintaining relative simplicity while achieving versatility.
Solution Approach 2:
The physical parameter of distance between backing members is made variable through adjustment mechanisms. By changing this parameter, the backing member group structure can accommodate different welding configurations and groove sizes, providing adaptability without significantly increasing structural complexity.
4Manufacturing precision
If conventional backing apparatus is used for multiple welds, then each weld can be formed, but the installation and removal process becomes time-consuming and cumbersome
Solution Approach 1:
The backing members are designed as segmented, modular units within a group structure that can be quickly installed and removed as a coordinated unit. This segmentation allows for efficient installation and removal compared to conventional apparatus, as the modular design enables rapid positioning and adjustment without time-consuming assembly operations.
Solution Approach 2:
The backing members are pre-configured in a group structure with predetermined spacing and positioning features. This preliminary arrangement allows for quick installation and removal without requiring time-consuming on-site assembly or adjustment, thereby reducing the time loss associated with installing and removing conventional backing apparatus for multiple welds.
