Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a coupling device is designed to accommodate various pipe sizes and types, then adaptability is improved, but device complexity increases
Solution Approach 1:
The coupling device incorporates a universal coupling mechanism that can connect to different pipe sizes and types through adjustable components. The coupling device includes a first coupling member with a first coupling flange and a second coupling member with a second coupling flange, where the flanges can be adjusted to accommodate various pipe configurations, allowing a single device design to serve multiple connection requirements.
Solution Approach 2:
The coupling device employs dynamic adjustment capabilities through movable and adjustable components. The coupling members include adjustable elements that can be positioned at different angles and orientations, allowing the device to adapt to various pipe arrangements. This dynamic adjustability enables the same coupling device to accommodate different pipe sizes and types without requiring multiple specialized devices.
2Ease of operation
If the coupling device uses standard flange connections, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The coupling device incorporates adjustable parameters in the flange design, including variable hole positions and adjustable coupling member orientations. These parameter changes allow the flanges to accommodate different pipe sizes and types while maintaining standard connection interfaces. The adjustability compensates for manufacturing variations and ensures proper alignment without requiring extremely tight manufacturing tolerances.
Solution Approach 2:
The coupling device acts as an intermediary component between different pipe systems. The coupling members include intermediate adjustment mechanisms that mediate between the standard flange connection requirements and the specific pipe configuration needs. This intermediary function allows standard flanges to be used across different pipe types while the adjustable components handle the precision alignment requirements.
3Ease of operation
If the coupling device is designed for easy disassembly and reassembly, then ease of operation is improved, but reliability may worsen
Solution Approach 1:
The coupling device is segmented into separate coupling members that can be independently assembled and disassembled. The first coupling member and second coupling member can be separated from the pipe fittings, allowing for easy disassembly and reassembly. This segmentation maintains reliability by ensuring that each component can be properly connected through standardized interfaces while enabling flexible installation and maintenance operations.

AI summary
A coupling device is disclosed for coupling a container to a closure. The container has a container sidewall extending between a first container end and a second container end. A container undercut is defined in an outer surface of the container sidewall. The closure has a closure sidewall extending between a first closure end and a second closure end. A closure outer sidewall is located radially outward from the closure sidewall and defines a slot between the closure sidewall and the closure outer sidewall. The second container end is received within the slot of the closure. A major projection and a major depression are located between the second container end and the slot of the closure cooperating for securing the closure to the container. A minor projection and a minor depression located between the container sidewall and the closure sidewall for cooperating for additionally securing the closure to the container.
