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.
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.
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.
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Procurement actually means well. There is no question that procurement can do a better job of phrasing their questions or making connections between engineering’s goals and the processes underway. And if you are using the right deciphering code, the result can live up to -- or surpass -- your expectations.
If you are interested in adding FPGA technology to you engineering toolkit, grab some free tools and an evaluation kit and get started on your own FPGA project. It never hurts to expand your engineering toolbox, and FPGAs are only going to become more popular over the next few years.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
