Design Decisions: Understanding the Value of Integrated System Design
This diesel engine emission control module manages fuel, air atomization, and air purge functions. Integrated into this assembly are two solenoid valves, two pressure regulators, three pressure transducers, a fuel injector, and precision orifice. The compact design and simplified mounting provide a distinct advantage over having to connect and mount individual components on a truck chassis.
Mr. Fleischer, thank you for a good white-paper blog. You did not make it an advertisement for your company or products. Granted, the image shown was likely your product, but it in no way sold that product or even identified it. It was a good example of integrated system design.
It is certainly true that for many systems that utilize either hydraulics, or pneumatics, that using a manifold for some of the interconnects can provide a much more compact system that is both more reliable and less expensive. In fact, this holds true for both mass production and one-off systems, which is unusual. Of course the down side is that the system must be defined prior to the manifold being designed, since most manifolds are difficult to revise. But once a system is accurately defined a well designed manifold will usually provide a cost reduction, and almost always provide better reliability.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
Pressure vessels are part of common equipment utilized in plants to store liquids and gases under high pressure. It is certain that pressurized fluids will develop stresses in the vessel, which when exceeds failure limits, will lead to hazardous incidents and fatalities.
