Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional electrophoretic process is used to electrophorese the assembled angle adjuster by immersing it in a liquid, then corrosion and rust resistance is improved, but electrophoretic liquid enters the interior of the angle adjuster via gaps, leading to increased operational torque and affecting normal function
Solution Approach 1:
The clamping ring is pre-shaped to form a clearance fit with the gear toothed plate before electrophoresis, creating a preventive barrier that stops electrophoretic liquid from entering the interior gaps, thus preventing the harmful effect before it can occur
Solution Approach 2:
The clamping ring acts as an intermediary component between the gear toothed plate and the external environment, using its shaped clearance fit to block the path of electrophoretic liquid while still allowing the necessary assembly structure
2Object-affected harmful factors
If gaps between components are reduced to prevent liquid infiltration, then electrophoretic liquid infiltration is prevented, but manufacturing complexity increases due to additional shaping operations
Solution Approach 1:
The clamping ring serves multiple functions: it clamps the gear toothed plate, provides structural support, and through its shaped configuration, prevents electrophoretic liquid infiltration. This multi-functionality reduces the need for additional separate components
3Object-affected harmful factors
If the clamping ring is shaped to reduce gaps, then electrophoretic liquid infiltration is prevented, but manufacturing time and energy increase due to additional shaping operations
Solution Approach 1:
The clamping ring is shaped during the manufacturing process before assembly, so that when assembled, the clearance fit is already optimized to prevent liquid infiltration. This preliminary action avoids the need for time-consuming adjustments or modifications after assembly

Function Achieved in This Case
The solution effectively prevents electrophoretic liquid from entering the angle adjuster, maintaining normal function and reducing operational torque by controlling gaps and using anti-electrophoretic liquid grease and a metal cover cap.
Implementation Method 1
a short edge of the clamping ring is fixedly connected to an end of the gear ring toothed plate by a laser welding seam

AI summary
The present invention relates to an anti-electrophoretic liquid infiltration angle adjuster, comprising a gear toothed plate and a gear ring toothed plate which can rotate relative to each other; and a clamping ring for holding the gear toothed plate and the gear ring toothed plate together, one end of the clamping ring being fixedly connected to the gear ring toothed plate, and the other end of the clamping ring being bent towards the gear toothed plate so as to form a clearance fit with the gear toothed plate. The present invention further relates to an assembly method for the anti-electrophoretic liquid infiltration angle adjuster. According to the anti-electrophoretic liquid infiltration angle adjuster of the present invention, a gap is controlled by means of bending and shaping of the clamping ring, and impurities such as electrophoretic liquid are prevented from entering the interior of the angle adjuster, thereby preventing the normal function of the angle adjuster from being affected. The impurities such as electrophoretic liquid may be further prevented from entering the interior of the angle adjuster by means of controlling a gap between a drive cam and the gear toothed plate. Gaps at two ends of a cover cap is controlled by means of selecting a metal cover cap to be the cover cap, and the impurities such as electrophoretic liquid may be further prevented from entering the interior of the angle adjuster.
