Valve Combination Ring Anti-Twist Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valves for door or window drives are complex and costly to manufacture due to the need for grooves in the thread to accommodate an elastic element, which can lead to a decrease in anti-twist effectiveness over time as the thread is cut.
Innovation Solution
A combination ring formed from a sealing ring and a locking ring, molded in one piece during the manufacturing process, prevents unintentional twisting by maintaining a high coefficient of friction and sealing the hydraulic fluid, eliminating the need for grooves in the thread.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If grooves are made in the thread to accommodate an elastic element, then the valve is secured against twisting, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent combines the sealing ring and locking ring into a single integrated component called a combination ring. This eliminates the need for separate grooves in the thread, as the combination ring itself provides both sealing and anti-twist functionality through its integrated structure, thereby simplifying manufacturing while maintaining reliability
Solution Approach 2:
The combination ring serves multiple functions simultaneously: it provides sealing against hydraulic fluid leakage and prevents unintentional valve adjustment through its anti-twist mechanism. This multi-functional design eliminates the need for separate components and grooves, reducing manufacturing complexity while maintaining both sealing and anti-twist effectiveness
2Reliability
If grooves are cut in the thread, then the elastic element can be accommodated, but the thread flanks are damaged and anti-twist effect decreases over time
Solution Approach 1:
By integrating the sealing and locking functions into a single combination ring component, the patent eliminates the need to cut grooves in the thread. The combination ring engages with the thread externally without compromising the thread flanks, thereby maintaining anti-twist effectiveness over time without damaging the thread structure
Solution Approach 2:
The combination ring is designed as a separate, pre-formed component that can be manufactured independently and then installed onto the valve. This segmentation allows the anti-twist and sealing functions to be achieved without modifying the thread structure, preserving thread integrity and durability
3Ease of manufacture
If a combination ring is molded in one piece, then manufacturing is simplified and costs are reduced, but the anti-twist mechanism must be maintained
Solution Approach 1:
The combination ring integrates both the sealing ring and locking ring functions into a single molded component. The anti-twist functionality is achieved through the integrated structure itself, which combines sealing and locking features without requiring separate parts or complex assembly, thereby maintaining reliability while simplifying manufacturing
Solution Approach 2:
The combination ring can be manufactured using injection molding or similar processes that allow complex geometries to be formed in one piece. The design incorporates both sealing surfaces and anti-twist engagement features within a single composite structure, achieving both manufacturing simplicity and functional reliability

AI summary
The valve (8) has valve main structure (9) and valve cone (10). The valve main structure is provided with ring-shaped groove (14). The groove is arranged with sealing ring (18). The annular groove (13) of valve main structure is located perpendicular to recess (15). The annular groove and recess are formed in integral combination ring (16) for securing and sealing valve main structure opposite to rotation direction.
