Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the main plate and bracket are spray-coated or electroplated separately before assembly, then the surface treatment can be completed, but the surface processing efficiency is low and production cost is high due to multiple treatment steps
Solution Approach 1:
The patent merges the surface treatment process by performing spray-coating or electroplating on the assembled main plate and bracket as a single integrated operation, rather than treating them separately before assembly. This is achieved by designing the connecting structure with concentric circular trajectories that ensure both components are uniformly covered in one treatment cycle, thereby improving surface processing efficiency while maintaining treatment quality
Solution Approach 2:
The patent applies preliminary action by assembling the main plate and bracket before surface treatment, with the connecting parts positioned in advance to enable one-time coating. The concentric circular trajectory design is prepared in advance to ensure complete coverage during the single surface treatment operation, eliminating the need for subsequent treatment steps
2Manufacturing precision
If the bracket rotates to adjust angles for complete surface coverage, then all visible surfaces can be treated, but the treatment efficiency remains low and rivet use increases cost
Solution Approach 1:
The patent employs spheroidality by designing the connecting parts with concentric circular trajectories. This curved geometric design ensures that as the bracket rotates, all surfaces follow a circular path that is uniformly covered by the spray-coating or electroplating process in a single operation, eliminating the need for multiple angle adjustments and reducing treatment time
Solution Approach 2:
The patent achieves continuity of useful action by enabling the surface treatment process to cover all visible surfaces of both the main plate and bracket in one continuous operation. The concentric circular trajectory allows the coating to be applied continuously as the bracket rotates, without interruption or need to stop for angle adjustments, thereby reducing total treatment time
3Stability of the object's composition
If rivets are used to connect the main plate and bracket, then the structure is assembled, but processing cost increases and surface treatment quality deteriorates due to gaps and rust
Solution Approach 1:
The patent extracts and eliminates the rivet component from the connecting structure. By removing the rivet, the source of gaps and potential rust points is eliminated, allowing for continuous surface treatment without interruption or quality degradation. The connection is achieved through the integrally formed connecting parts with concentric circular trajectories
Solution Approach 2:
The patent applies composite materials by using integrally formed connecting parts made from the same material as the main plate and bracket. This integral construction ensures uniform material properties throughout the assembly, eliminating dissimilar metal contact that could cause galvanic corrosion, and allows for uniform surface treatment across all components

AI summary
The present invention discloses a method for surface treatment of a supporting frame. The supporting frame includes a main plate body and a bracket body which are rotatably connected. The main plate body and the bracket body are connected through a connecting structure. The main plate body is assembled with the bracket body. The main plate body and the bracket body are respectively provided with a main plate connecting part and a bracket connecting part. Surface treatment is performed on the assembled supporting frame. An included angle between the main plate body and the bracket body during surface treatment is a first included angle. After treatment, when the bracket body rotates around the main plate body to a second included angle, a surface treatment agent is distributed in any area of working surfaces of the main plate connecting part and the bracket connecting part. The first included angle is different from the second included angle. The present invention can complete the surface treatment of the supporting frame in one time, reduce the production cost of the enterprise, and improve the processing efficiency of the supporting frame.
