Valve Body End Connections for Late 3D-Printed Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The valve manufacturing industry faces challenges due to high product variation and low quantity production, leading to excess inventory and long lead times caused by customer-specific inlet and outlet end connection configurations, which rely heavily on sales forecasting and are difficult to meet with traditional sand casting processes.
Innovation Solution
The method involves using additive manufacturing processes to customize valve body end connections on a per-order basis, allowing for the modification of initial end connections into custom configurations, reducing the need for customer-specific inventory and enabling quick adaptation to varying customer requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sales forecasting is used to manufacture customer-specific valves in advance, then customer demand can be met, but inventory levels increase and production capacity is wasted
Solution Approach 1:
The patent applies preliminary action by manufacturing generic valve bodies in advance without customer-specific end connections, then adding custom end connections later through additive manufacturing. This allows the base valve body to be prepared beforehand while the customization happens on-demand, reducing inventory of finished customer-specific valves while maintaining ability to fulfill demand quickly.
Solution Approach 2:
The patent segments the valve manufacturing process into two distinct phases: (1) manufacturing of generic valve bodies without customer-specific end connections, and (2) addition of custom end connections through additive manufacturing. This segmentation allows the common portion to be produced in advance while the variable portion is customized later, reducing overall inventory requirements.
2Productivity
If sand casting is used to manufacture valve bodies, then production capacity is maintained, but production lead time is too long to meet rush orders
Solution Approach 1:
The patent applies preliminary action by completing the valve body manufacturing through sand casting in advance, then rapidly adding custom end connections through additive manufacturing when orders are received. This allows the time-consuming sand casting process to be performed beforehand, while the final customization happens quickly on-demand.
Solution Approach 2:
The patent introduces dynamics by transitioning from static, fully-customized valve manufacturing to a dynamic two-stage process where generic valve bodies are produced in advance and then dynamically customized with additive manufacturing based on actual customer orders and lead time requirements.
3Adaptability or versatility
If customer-specific end connection configurations are manufactured for each customer, then customer requirements are met, but product variation increases and inventory complexity increases
Solution Approach 1:
The patent applies universality by creating a generic valve body design that can serve multiple customers with different end connection requirements. The standardized valve body acts as a universal base that can be customized with different end connections through additive manufacturing, reducing the number of unique valve body designs needed in inventory.
Solution Approach 2:
The patent segments the valve into a universal base component (valve body without end connections) and customer-specific components (end connections added through additive manufacturing). This segmentation allows the universal portion to be manufactured once and reused for multiple customers, while only the variable end connection portions need to be customized.

Function Achieved in This Case
This approach reduces inventory levels, decreases reliance on sales forecasting, and shortens production lead times by allowing for late customization of valve bodies using generic configurations, enabling efficient production and delivery of customer-specific valves.
Implementation Method 1

AI summary
A method is provided of custom manufacturing a valve body having an initial valve body configuration having a first end connection and a second end connection. The method includes adding material to the first end connection using a first additive manufacturing process to create at least a portion of a custom first end connection configuration, and the custom first end connection configuration is different than an initial first end connection configuration. The method further includes adding material to the second end connection using a second additive manufacturing process to create at least a portion of a custom second end connection configuration, and the custom second end connection configuration is different than an initial second end connection configuration.
