Electrical & Wire Harness Design Blog

I like going to trade shows - usually I am one of the many people doing “booth duty” - standing in the booth chatting with people and doing demonstrations.  Often I get to talk to some fine folks that have nothing whatsoever to do with electrical harness design and just want whatever trinket we are giving away - but you meet some interesting people and sometimes learn a little bit. This year the general … Read More

I read an interesting article at http://www.physorg.com/news183361139.html by Lin Edwards that describes a new single person electric aircraft that and hover like a helicopter and fly like a plane.  As quoted by Lin: The cruising speed of the Puffin is expected to be 240 kph, with spurts of 480 kph possible. The engine does not require air, which means its flight capabilities are not limited by thin … Read More

Often when we are creating wiring diagrams we are limited by our page size for content - sometimes as small as 8.5″x11″ often 11″x17″.  I have designed using both - and used both in the field.  I can tell you I prefer to draw on 11″x17″ but when I am in the field troubleshooting I would rather handle and carry a smaller stack of paper. A helpful construct now in Mentor Graphic’s Capital Harness System … Read More

The differences in documentation standards for electrical design are as vast as the number of stars in the sky.  No two are alike, no matter what the claims - there is always “something” different.  If your company provides documentation to more than one customer then the problem is even greater.  The problem is lies with the tools being used to create the drawings.  Typically I see companies trying … Read More

What is EWIS?  EWIS stands for Electrical Wiring Interconnection System which can be defined as at set of electrical connections and signals between devices and modules and all of their associated termination parts which are necessary for their installation.  In other words, this defines the set of electrical diagrams and cable harnesses that are installed in an airplane or a helicopter that make all … Read More

Standards inject certainty into your working life. Last week I wrote about how the development of standards and the easiest pathway to adoption of them. Adherence to standards is an integral part of successful engineering. The most attractive standards: lack complexity - are easy to understand - clear and straightforward for a person like you turn out to be robust for the niche in which you operate - … Read More
