Integrated Fluid Control Sealing Assembly to Prevent Seal Dislocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid control systems face challenges in maintaining effective sealing performance due to the risk of sealing member misplacement or dislocation during transportation and transshipment, which can lead to fluid leakage and increased complexity in assembly.
Innovation Solution
A fluid control assembly is designed with a housing and a sealing member formed as an integral structure through dual-color injection molding, where the sealing member includes a main body and a protruding outer extension part that forms a closed-loop structure, ensuring secure connection and reduced risk of dislocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sealing member is assembled separately from the housing, then the assembly process is more flexible, but the sealing member may become dislocated or fall off during transportation and transshipment
Solution Approach 1:
The sealing member and housing are merged into an integral structure through dual-color injection molding, eliminating the risk of dislocation while maintaining assembly efficiency. The sealing member becomes a permanent part of the housing, ensuring it cannot fall off or become misaligned during transportation.
Solution Approach 2:
The sealing member is pre-formed within the housing during the injection molding process, before the assembly undergoes transportation or assembly operations. This preliminary positioning ensures the sealing member is already in its correct position and cannot become dislocated later.
2Ease of repair
If the sealing member is assembled separately from the housing, then replacement and maintenance are easier, but the number of parts increases and assembly complexity increases
Solution Approach 1:
By merging the sealing member and housing into a single integral structure, the number of parts is reduced and assembly complexity is minimized. The sealing function is built-in rather than added through separate components.
3Reliability
If the sealing member is made as an integral structure with the housing, then the risk of dislocation is reduced, but the manufacturing process becomes more complex
Solution Approach 1:
The manufacturing process utilizes dual-color injection molding, which changes the material parameter (from single-material to multi-material molding) to achieve the integral structure. This parameter change enables the sealing member and housing to be formed as one piece with different materials in a single manufacturing step.
Solution Approach 2:
The dual-color injection molding process employs composite materials - typically a rigid material for the housing and a softer sealing material for the sealing member - to create an integral structure that combines the advantages of both materials while eliminating the need for separate assembly.
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
This configuration enhances sealing performance by preventing the sealing member from falling off or becoming dislocated, simplifies assembly, and reduces the number of parts required, thereby improving reliability and ease of use.
Implementation Method 1
By means of a dual-color injection molding process, the housing and the sealing member are injection molded, and the sealing member and the housing are fixedly connected into an integral structure.

AI summary
A fluid control assembly and a fabrication method therefor. The fluid control assembly comprises a housing and a sealing member. The housing comprises a first mounting main body having a mounting surface, and the housing is provided with at least two passages and an accommodating groove which surrounds the passages. The accommodating groove extends from the mounting surface to the interior of the first mounting main body. The sealing member has the same number of first through holes as that of the passages, and the first through holes correspond to and communicate with the passages of the housing. The sealing member comprises a main body part and a first outer extension part which are connected to one another. Along the height direction of the main body part, the first outer extension part protrudes from the main body part.
