Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a suction lance is designed for a specific connection arrangement, then it achieves reliable operation with that container type, but it cannot be used with containers having different connection arrangements and diameters
Solution Approach 1:
The guide body is designed to perform multiple functions: it guides the tube during insertion and simultaneously acts as a sealing body against the container wall. This multi-functionality allows the suction lance to be universally applicable to different container types without requiring separate components for each container configuration.
Solution Approach 2:
The conical section of the guide body can adapt to different opening diameters through elastic deformation. The elastomer material allows the guide body to change its dimensional parameters (radial size) to match various container opening sizes while maintaining sealing effectiveness.
2Reliability
If a rigid sealing body is used to ensure reliable sealing, then sealing effectiveness is improved, but it cannot adapt to different opening diameters
Solution Approach 1:
The guide body is made from elastomer material that forms a flexible shell structure. This flexibility allows the sealing surface to deform and conform to different container opening diameters while maintaining reliable sealing, eliminating the need for rigid sealing components.
Solution Approach 2:
The elastomer material enables the guide body to change its physical parameters (shape and size) in response to different opening diameters. The material's elastic properties allow it to be compressed or expanded to match various container configurations while maintaining sealing integrity.
3Adaptability or versatility
If separate sealing components are added to achieve sealing on different containers, then sealing capability is improved, but device complexity increases
Solution Approach 1:
The sealing function is merged with the guide body structure itself. The conical section of the guide body directly contacts and seals against the container wall, eliminating the need for separate sealing rings, gaskets, or sealing components. This integration reduces device complexity while maintaining sealing capability.
Solution Approach 2:
The guide body serves multiple purposes: guiding the tube during insertion and providing sealing against the container wall. This multi-functionality eliminates the need for additional sealing components, simplifying the overall device structure while achieving universal sealing capability across different container types.

AI summary
A suction lance comprising at least one tube and a guide body made from an elastomer material axially displaceable on this tube is provided. The suction lance comprises a retaining section for a connecting body, a conical section axially adjoining the retaining section, the radially largest section whereof lies axially closer to the retaining section than the radially smallest section thereof, and a connecting body for the detachable connection of the suction lance to a removal opening of a container. The connecting body is fastened to the retaining section of the guide body, and the conical section of the guide body, by reason of its material, its radial size and the shape of its external contour, is designed to act in case of use as a sealing body in a removal opening of a container.
