Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw connections are used to connect pressure accumulators to connecting devices, then the connection is secure and reliable, but the assembly and disassembly process becomes time-consuming and complex
Solution Approach 1:
The connection device is divided into separate components: a connecting piece with external threading and a receiving piece with internal threading. The pressure accumulator body is segmented to include a separate connecting segment with bore structures. This segmentation allows for simplified assembly where components can be connected by inserting the connecting piece into the receiving piece and securing with a locking element, rather than requiring complex screw fastening procedures, thus reducing assembly time while maintaining connection reliability.
Solution Approach 2:
The connecting segment is pre-configured with bore structures (first bore, second bore, third bore) and sealing elements are pre-installed in predetermined positions. The connecting piece and receiving piece are designed with pre-aligned features that guide proper insertion. This preliminary preparation of connection interfaces eliminates the need for complex alignment and fastening operations during assembly, significantly reducing assembly time while ensuring reliable and leak-free connections.
2Volume of moving object
If multiple pressure accumulators are combined in a module with common access, then space efficiency is improved, but the complexity of connection and maintenance increases
Solution Approach 1:
The connecting device employs universal connecting pieces and receiving pieces that can be standardized across multiple pressure accumulators in a module. The same connecting piece design with external threading and locking features can interface with identical receiving piece designs on different accumulators. This universality allows multiple accumulators to be combined in a module with common access points, improving space utilization while keeping connection procedures simple and maintenance straightforward through standardized interfaces.
Solution Approach 2:
Multiple pressure accumulators are merged into a single module structure where individual accumulators share common connecting devices and access points. The connecting pieces and receiving pieces are designed to facilitate this merging by providing standardized interfaces that allow accumulators to be connected in series or parallel configurations. This merging approach improves space efficiency while the standardized connection design keeps the overall system complexity manageable through modular architecture.
3Productivity
If simple connection methods are used for rapid assembly, then assembly time is reduced, but connection reliability and sealing performance may be compromised
Solution Approach 1:
The connection system incorporates self-sealing features where sealing elements (such as O-rings or gaskets) are automatically compressed and positioned when the connecting piece is inserted into the receiving piece. The geometry of the bores and connecting surfaces is designed to self-align components and automatically engage sealing features without requiring additional sealing operations or complex fastening procedures. This self-service mechanism enables rapid assembly while ensuring reliable sealing and connection integrity.
Solution Approach 2:
Sealing elements act as intermediaries between the connecting piece and receiving piece, mediating the connection interface. These sealing elements are strategically positioned in the bore structures and are compressed upon insertion to create reliable seals. The intermediary sealing mechanism allows for simple insertion-based assembly while maintaining high connection reliability and preventing leaks, thus achieving both rapid assembly speed and dependable connection performance.
