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 coating processes
Solution Approach 1:
The patent merges the main plate and bracket into a unified assembly structure where the bracket is rotatably connected to the main plate through a connecting structure. This allows both components to be spray-coated or electroplated together in one continuous process, eliminating the need for separate coating operations before assembly. The connecting structure includes a connecting plate with through-holes that accommodates rivets, enabling the riveting process to occur after the unified surface treatment, thus improving surface processing efficiency while maintaining treatment quality.
2Strength
If rivets are used to connect the main plate and bracket, then the structural connection is achieved, but the surface treatment becomes uneven and production cost increases
Solution Approach 1:
The patent applies preliminary action by performing the surface treatment (spray-coating or electroplating) on the entire assembly before the riveting operation. The connecting plate is designed with through-holes that allow rivets to pass through after coating, ensuring that the riveting process does not disturb the already applied surface treatment layer. This sequence reversal - treating surfaces first, then connecting with rivets - eliminates the problem of uneven coating around rivet holes while maintaining strong structural connection.
3Manufacturing precision
If the bracket body rotates to adjust angles for complete surface coating, then the entire surface can be treated, but the treatment efficiency decreases and rivets are still required
Solution Approach 1:
The patent incorporates dynamics by designing the bracket as a rotatable component connected to the main plate through the connecting structure. The bracket can rotate around the riveting part to achieve different working angles, and this rotational capability is utilized after the unified surface treatment is completed. The dynamic rotation feature allows the bracket to be positioned at various angles for different cable routing configurations without requiring re-coating, thereby maintaining complete surface coverage while improving treatment efficiency by eliminating the need for angle adjustments during the coating process itself.

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. 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.
