Modular Vacuum Breaker Valve Assembly for Individual Component Sales
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional freeze-safe valves are only available for wholesale and cannot be sold individually, limiting user assembly and increasing costs due to their integrated design.
Innovation Solution
A vacuum breaker valve design featuring a valve body with air vent holes and a pre-assembled vacuum breaking device, comprising a mounting barrel, elastic member, braking member, mounting plate, water stop gasket, and water inlet disk, allowing for easy assembly and individual sales of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vacuum breaking device is integrated into the valve body as a single unit, then the structural integrity and reliability are improved, but the ease of manufacture and adaptability deteriorate due to inability to sell components individually
Solution Approach 1:
The vacuum breaking device is divided into separate components (mounting barrel, elastic member, braking member, mounting plate, water stop gasket, water inlet disk) that can be manufactured and sold independently, then assembled by the user into the valve body. This segmentation allows individual component sales while maintaining reliable assembly through standardized interfaces and positioning features.
2Device complexity
If the vacuum breaking device is integrated into the valve body, then the device complexity is reduced, but the ease of manufacture deteriorates due to inability to produce components separately
Solution Approach 1:
The device is segmented into modular components that can be manufactured using different processes and materials independently, then assembled together. This allows each component to be optimized for its specific manufacturing requirements while maintaining a relatively simple overall structure through standardized connection interfaces.
Solution Approach 2:
The vacuum breaking device components are pre-assembled as a complete functional unit with all positioning features (positioning portions, positioning groove, positioning convex portion, positioning concave portion) already in place. This preliminary assembly simplifies the final installation into the valve body while allowing flexible component production.
3Manufacturing precision
If the vacuum breaking device components are designed with multiple positioning features, then the assembly precision is improved, but the device complexity increases
Solution Approach 1:
The positioning features are distributed across different components (positioning portions on braking member, positioning groove on mounting plate, positioning convex portion on water stop gasket, positioning concave portion on water inlet disk) rather than concentrated in one complex feature. This segmentation achieves high assembly precision through multiple simple interfaces.
Solution Approach 2:
The positioning features are designed to automatically align components during assembly without requiring external tools or complex adjustment mechanisms. The positioning portions, groove, and convex/concave features self-align the components when assembled, achieving high precision through the assembly process itself rather than through complex individual component design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates user assembly and reduces fabrication costs by enabling the vacuum breaking device to be assembled and fitted into the valve body, allowing for both combined and individual sales, effectively addressing the limitations of existing designs.
Implementation Method 1
The elastic member is a compression spring. The elastic member has a lower end pressing the stepped rim. The elastic member has an upper end pressing the positioning portions.

AI summary
A vacuum breaker valve includes a valve body and a vacuum breaking device mounted in the valve body. The valve body has a periphery provided with multiple air vent holes corresponding to the vacuum breaking device. The vacuum breaking device includes a mounting barrel, an elastic member, a braking member, a mounting plate, a water stop gasket, and a water inlet disk. The vacuum breaking device is assembled previously and then directly fitted into the valve body to construct the vacuum breaker valve. Thus, the vacuum breaking device and the valve body are combined together for a whole sale or the vacuum breaking device and the valve body are sold individually.
