Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure reducing apparatuses have a complex structure with multiple components, leading to increased manufacturing costs and reduced assembly operability.
Innovation Solution
A pressure reducing apparatus with a simplified design featuring a diaphragm, guide member, and a spring that urges the diaphragm to separate from the port, reducing the number of parts and allowing for easier assembly, while maintaining the ability to adjust the pressure fluid's pressure value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a valve plug, stem, and spring are disposed separately as in conventional pressure reducing apparatus, then the structural integrity and reliability are maintained, but the number of parts increases leading to higher manufacturing costs and reduced assembly operability
Solution Approach 1:
The patent combines the valve plug, stem, and spring into an integrated assembly where the spring is positioned within the valve plug structure. This merging reduces the total number of discrete parts while maintaining the functional integrity of each component, directly addressing the contradiction between manufacturing cost and device complexity
2Productivity
If multiple separate components are used in the pressure reducing apparatus, then the reliability and functional performance are ensured, but the assembly operability and manufacturing efficiency are reduced
Solution Approach 1:
The patent segments the pressure reducing apparatus into functional modules: the diaphragm assembly, the integrated valve plug-spring assembly, and the body. This segmentation allows for simplified assembly of reliable sub-assemblies while maintaining overall structural reliability, resolving the contradiction between productivity and reliability
3Device complexity
If the number of parts is reduced in the pressure reducing apparatus, then manufacturing costs and assembly complexity are lowered, but the ability to maintain precise pressure control may be compromised
Solution Approach 1:
The patent maintains pressure control precision by optimizing the spring constant and pre-load parameters within the integrated assembly. By carefully selecting spring parameters, the system achieves precise pressure regulation despite the reduced number of components, resolving the contradiction between device complexity and manufacturing precision
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
The solution reduces the number of components and manufacturing costs, improves assembly efficiency, and allows for flexible adjustment of the pressure value by modifying the spring's elastic force, effectively maintaining the pressure fluid at a desired value.
Implementation Method 1
a spring interposed between the body and the diaphragm, which urges the diaphragm in a direction to separate from the port

AI summary
The present invention relates to a pressure reducing apparatus. A diaphragm made from an elastic material is provided in the interior of a body. The diaphragm includes a main body portion having a seat member that is capable of being seated on an inner tubular member of the body, a retaining portion disposed on an outer peripheral side of the main body portion and which is slidably displaceable with respect to the inner tubular member, and a skirt that is retained on a flange of the body. Additionally, by flexing of the skirt by means of an elastic force of a spring, the seat member thereof separates away from the inner tubular member.
