Hinged Armature Valve Assembly With Adjustable Stroke Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetically actuated hinged armature valve devices face challenges in large-scale production due to complex adjustment of the armature stroke, which affects sealing and pressure conditions, leading to increased costs and limited applicability.
Innovation Solution
The coil carrier assembly and valve seat assembly are adjustable relative to each other, allowing precise adjustment of the pivoting or folding stroke without additional mechanical assemblies, and are connected using weldable polymer materials for a permanent, pressure-tight seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional mechanical means such as adjustment screws are used to adjust the armature stroke, then the pivoting or folding stroke can be adjusted, but the device complexity increases and sealing effort increases
Solution Approach 1:
The patent removes additional mechanical adjustment means (screws, levers, etc.) from the device structure. Instead, the armature stroke is adjusted by modifying the geometric parameters of existing components during molding - specifically by changing the position of the armature pivot point or the length of the armature lever, which are built into the structure during manufacturing rather than requiring separate adjustment mechanisms.
Solution Approach 2:
The patent changes geometric parameters of components during the molding process to achieve stroke adjustment. By varying the position coordinates of pivot points, the length of lever arms, or the angle of mounting, different armature strokes are obtained without adding mechanical adjustment means. This parameter-based approach allows stroke customization through manufacturing parameters rather than mechanical modifications.
2Adaptability or versatility
If additional mechanical means are used to adjust the armature stroke, then the pivoting or folding stroke can be adjusted, but the sealing effort and risk of leaks increase
Solution Approach 1:
The patent eliminates additional mechanical adjustment components that would create extra sealing interfaces. By integrating the adjustment function into the geometric design of existing molded parts, the number of sealing surfaces remains minimal, thereby maintaining high sealing reliability without compromising stroke adjustability.
Solution Approach 2:
The patent achieves stroke adjustment by changing manufacturing parameters (positions, dimensions) of components rather than adding mechanical means. This ensures that the armature chamber sealing structure remains simple and intact, with no additional sealing interfaces introduced by adjustment mechanisms, thus preserving sealing reliability.
3Adaptability or versatility
If complex mechanical adjustment means are used, then the armature stroke can be adjusted, but the manufacturing cost and production time increase
Solution Approach 1:
The patent removes complex mechanical adjustment assemblies from the device, reducing the number of parts to be manufactured and assembled. This simplification directly reduces manufacturing costs and assembly time, making the device suitable for large-scale production while retaining stroke adjustability through geometric parameter variations.
Solution Approach 2:
The patent implements stroke adjustment by varying geometric parameters during the molding process itself. Since the adjustments are built into the manufacturing parameters rather than requiring separate assembly steps with multiple components, the production process becomes more efficient and cost-effective for mass production.
4Adaptability or versatility
If additional mechanical means are used for stroke adjustment, then the armature stroke can be adjusted, but the device complexity and assembly effort increase
Solution Approach 1:
The patent eliminates separate mechanical adjustment components and their associated assembly operations. The stroke adjustment function is integrated into the molded structure itself, reducing the number of assembly steps and making the manufacturing process simpler and more suitable for automated large-scale production.
Solution Approach 2:
The patent merges the stroke adjustment function with the existing structural components. Instead of adding separate adjustment mechanisms, the adjustment capability is combined into the geometric design of the armature and its mounting structure, which are manufactured as integrated parts. This merging simplifies both manufacturing and assembly processes.
