Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for manufacturing diaphragms, such as molding and forming, require costly tooling and long lead times, making it difficult to quickly obtain or replace diaphragms, especially non-standard ones, in industrial valve systems where downtime needs to be minimized.
Innovation Solution
A method and system using three-dimensional printing to rapidly manufacture flexible diaphragms with varying materials and mechanical properties, allowing for the creation of diaphragms with specific characteristics without the need for extensive tooling or long lead times, by forming the entire diaphragm or selected portions with a 3D printer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional molding or forming methods are used to manufacture diaphragms, then the diaphragms can be produced with consistent quality and material properties, but the lead time is long and tooling costs are high
Solution Approach 1:
The patent changes the manufacturing process parameters from traditional molding to additive manufacturing (3D printing), enabling rapid production of diaphragms without requiring expensive tooling. This allows on-demand production with lead times reduced from weeks to days, while maintaining consistent quality through digital modeling and precise material deposition control
Solution Approach 2:
The patent employs disposable or replaceable support structures and sacrificial materials during the 3D printing process that are removed after manufacturing. This eliminates the need for expensive, long-lived tooling while enabling rapid iteration and production of custom diaphragm designs
2Productivity
If traditional molding or forming methods are used to manufacture diaphragms, then standardized diaphragms can be produced efficiently, but non-standard or custom diaphragms require new tooling and extended lead times
Solution Approach 1:
The 3D printing system serves multiple functions: it can produce both standardized and custom diaphragms using the same equipment and process. The digital modeling capability allows the system to switch between different diaphragm designs without physical tooling changes, providing universal manufacturing capability that combines efficiency with flexibility
Solution Approach 2:
The patent enables local customization of diaphragm properties by varying material composition, density, or structural characteristics in specific regions of the diaphragm during the 3D printing process. This allows non-uniform material properties to be incorporated into custom designs while maintaining overall production efficiency
3Reliability
If diaphragms are manufactured with traditional methods, then the production process is well-established and reliable, but the cost of tooling and long lead times make rapid replacement or modification impractical
Solution Approach 1:
The patent replaces the mechanical tooling-based manufacturing system with an additive manufacturing system that uses digital models and automated material deposition. This substitution maintains reliability through consistent digital processes while enabling rapid production and easy design modifications without the constraints of physical tooling
