Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plurality of elongate holes are connected individually to a pressure supply system, then each hole can receive pressure, but the connection process becomes complicated and time-intensive
Solution Approach 1:
The patent combines multiple individual connections to elongate holes into a single integrated connection block. The block contains multiple channels that simultaneously connect to multiple elongate holes, transforming a complex multi-step connection process into a single operation. This merging approach maintains reliable pressure supply to all holes while dramatically reducing connection complexity and time.
Solution Approach 2:
The connection block serves multiple functions simultaneously: it acts as a pressure distribution manifold, a structural support element, and a sealing interface. By designing a universal component that performs multiple roles, the patent eliminates the need for separate connection elements for each elongate hole, thereby simplifying the overall system while ensuring reliable pressure delivery.
2Reliability
If multiple ports are arranged densely at the second surface to match the channel density at the first surface, then all elongate holes can be connected, but the ports become difficult to access and connect to the pressure supply system
Solution Approach 1:
The patent distributes ports across multiple surfaces and dimensions rather than concentrating them all on a single plane. The second surface includes ports arranged on opposite sides and at different locations, utilizing three-dimensional space to provide adequate access to each port. This dimensional distribution allows all elongate holes to be connected while maintaining ease of operation for connecting the pressure supply system.
3Productivity
If the connection process is simplified with fewer ports, then the connection time is reduced, but not all elongate holes can be connected to different pressure sources
Solution Approach 1:
The connection block is segmented into multiple independent channels, each leading to a specific elongate hole. This segmentation allows each channel to be independently controlled and pressurized, providing flexibility to apply different pressures to different holes. The segmented design achieves this functionality without requiring individual external connections, thereby maintaining fast connection speed while enabling versatile pressure control.
