Vapor Separator Tank Regulator Support With Integrated Casing Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vapor separator tanks with pressure regulators require multiple parts and fixtures, increasing assembly time and manufacturing costs due to the complex support structure.
Innovation Solution
A vapor separator tank design that supports the pressure regulator using a simpler structure, eliminating the need for additional fixing parts by integrating a regulator support portion directly into the casing, which includes a flange and annular protrusion/recess configuration to secure the regulator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a holder and fixtures are used to support the pressure regulator between the lower case and upper case, then the pressure regulator is securely supported, but the number of parts and assembly complexity increases
Solution Approach 1:
The pressure regulator support function is merged into the lower case by forming a support protrusion directly on the lower case surface. This eliminates the need for separate holders and fixtures, reducing the number of parts while maintaining secure support of the pressure regulator. The support protrusion integrates the support function into the existing casing structure.
Solution Approach 2:
The lower case serves multiple functions: it contains the fuel storage compartment, provides structural support for the pressure regulator through the support protrusion, and acts as a mounting surface for the pressure regulator. This multi-functionality eliminates the need for dedicated support components.
2Reliability
If dedicated fixing parts are prepared to attach the holder to the casing, then the pressure regulator is firmly fixed, but manufacturing costs increase
Solution Approach 1:
The fixing function is merged into the lower case by forming the support protrusion as an integral part of the lower case structure. This eliminates the need for separate fixing parts and attachments, reducing manufacturing costs while maintaining firm fixation of the pressure regulator.
Solution Approach 2:
The lower case provides its own support and fixation function through the support protrusion, eliminating the need for external fixing components. The structure is self-sufficient, reducing manufacturing complexity and cost.
3Reliability
If multiple fixtures and holders are used to support the pressure regulator, then the regulator is stable, but assembly time increases
Solution Approach 1:
The support and fixation functions are merged into a single integrated structure (the support protrusion on the lower case), eliminating the need for multiple separate fixtures and holders. This reduces assembly steps and time while maintaining regulator stability.
Solution Approach 2:
The support function is segmented into a specific protrusion feature on the lower case, allowing the pressure regulator to be directly mounted on this integrated support structure without requiring separate assembly of multiple components.

AI summary
A VST (vapor separator tank) includes a casing including a lower case and an upper case joined to each other and having a fuel storage compartment formed therein to store liquid fuel, a pump arranged in the casing and pumping the liquid fuel stored in the fuel storage compartment, and a regulator (pressure regulator) sandwiched by the lower case and the upper case inside an accommodation space formed in the casing, and adjusting a discharge pressure of the pump to be constant. The casing includes a regulator support portion abutting on and supporting the regulator. Disclosed embodiments provide a vapor separator tank capable of holding a pressure regulator with a simpler structure and suppressing an increase in the number of parts, man-hours for assembly, and manufacturing costs.
