Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for forming fluid flow passages in metallic block members are time-consuming, costly, and complex, especially when forming narrow or curved passages, and often require multiple processes, leading to inefficiencies and difficulties in achieving accurate and hermetic connections.
Innovation Solution
A fluid flow passage structure and manufacturing method that uses metal block members and wires, where the wire is interposed between the block members to form airtight or fluidtight passages, allowing for a high degree of design freedom, miniaturization, and cost-effectiveness by simplifying the manufacturing process through pressing and heat integration, such as diffusion bonding or brazing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If photoetching or press processing is used to form fluid flow passages, then the passages can be formed in metal block members, but multiple processes are required and manufacturing time becomes considerable
Solution Approach 1:
The invention extracts the fluid flow passage formation process from the metal block member by introducing a separate groove member that is positioned between block members. This groove member is formed with fluid flow passages in advance, and then inserted into grooves of the block members, thereby separating the passage formation from the block machining process and reducing overall manufacturing time
Solution Approach 2:
The groove member is prepared in advance with fluid flow passages formed through processes like photoetching or press processing. This preliminary formation of passages in the groove member allows these time-consuming processes to be performed on a separate component that can be pre-manufactured and stored, rather than performing them on the final assembled structure
2Manufacturing precision
If laser illumination is used to form fluid flow passages, then passages can be created in metal plates, but the apparatus becomes large in scale and manufacturing costs increase
Solution Approach 1:
The invention extracts the fluid flow passage formation from the main metal block structure by using a separate groove member. This allows the use of more cost-effective formation methods on the groove member while maintaining the structural integrity of the metal blocks, avoiding the need for expensive laser apparatus on the final assembly
Solution Approach 2:
The groove member serves as a separate, replaceable component that can be manufactured using more economical processes. Rather than investing in expensive laser equipment for forming passages directly in the metal blocks, the invention uses a cheaper groove member that can be produced through less costly methods and then assembled into the final structure
3Manufacturing precision
If grinding process is used to form fluid flow passages, then passages can be created in split base pieces, but complex carving is necessary and manufacturing process becomes complicated
Solution Approach 1:
The invention extracts the complex fluid flow passage formation from the metal block members by using a separate groove member that is positioned between the blocks. The groove member is formed with passages in advance through simpler processes, and then inserted into the block members, thereby eliminating the need for complex grinding and carving operations on the final assembly
Solution Approach 2:
The invention segments the fluid flow passage formation into a separate groove member that is independent of the metal block members. This segmentation allows the passage formation to be performed on a separate component using simpler processes, and then the groove member is assembled into the final structure, reducing the complexity of the overall manufacturing process
4Manufacturing precision
If drill is used to form bent fluid flow passages, then passages can be created in block members, but the process becomes complex and requires additional parts like blind plugs
Solution Approach 1:
The invention extracts the bent fluid flow passage formation from the metal block members by using a separate groove member that is positioned between the blocks. The groove member is formed with bent passages in advance through simple processes, and then inserted into the block members, thereby eliminating the need for complex drilling operations and additional parts like blind plugs
Solution Approach 2:
Instead of forming passages by drilling from the outside of the metal blocks (which requires complex operations and additional parts), the invention inverts the approach by forming passages in a separate groove member and inserting it into the blocks. This inversion simplifies the formation process and eliminates the need for additional sealing parts
5Manufacturing precision
If narrow drill is used to form narrow fluid flow passages, then passages with diameter of 1 mm or less can be created, but the drill axis is deflected and accurate formation becomes difficult
Solution Approach 1:
The invention extracts the narrow fluid flow passage formation from the metal block members by using a separate groove member. The groove member is formed with narrow passages in advance through processes that do not suffer from drill axis deflection, and then inserted into the block members, thereby achieving accurate narrow passage formation without the reliability issues of using narrow drills
