Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welding quality is compromised due to spatters adhering to the protective apparatus during the welding process, leading to poor welding performance and reduced device performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective apparatus is used during welding, then the welding region is protected from spatters, but the spatters adhere to the protective apparatus surface reducing its service life and welding quality
Solution Approach 1:
The surface properties of the protective apparatus are changed by applying a thermally conductive coating, which fundamentally alters how the surface interacts with welding spatters. This parameter change enables the surface to rapidly cool and solidify spatters, preventing adherence and extending service life while maintaining welding quality
Solution Approach 2:
The protective apparatus uses a composite structure with a base material and a thermally conductive coating layer. This composite material design combines the protective function of the base structure with the thermal management properties of the coating, creating a surface that can handle high-temperature spatters without degrading
2Ease of operation
If the protective apparatus surface is made smooth, then spatters can slide down easily, but the surface area for heat transfer is reduced
Solution Approach 1:
The thermally conductive coating changes the thermal parameters of the surface, enabling rapid heat transfer that compensates for the reduced surface area. The high thermal conductivity ensures that even with a smooth surface, enough heat is transferred to quickly solidify spatters and enable them to slide down
