In this episode of Munro Live Cory and Sandy introduce and explain to the audience the different electrical connectors used in the vehicle and more importantly the different fasteners.
There are four different fasteners of different sizes and screw head types found throughout the different fastener styles. Sandy goes on to explain why this creates issues from the assembly operator’s perspective and why you should eliminate this in a lean design.
From the DC to DC converter, to the PTC Heater, HVAC Compressor, and so on, Cory walks the viewers through the different devices found within the vehicle and what connectors you will find on them. Sandy then compares these connectors to what is found on the ID.4 and gives high praise for what the design team at Volks Wagen came up with. Sandy is much more impressed with the continuity and simplicity of the connector set on the ID.4. However, he still doesn’t like that there are too many fasteners on VW’s design as well.
Sandy then moves to the Tesla Model Y and compares it’s connector designs to the Mach-E and ID.4 showing how much more simplified their design is compared to the competition.
Sandy takes some time to explain why it is so important to reduce the variety of threaded fasteners and moreover, why to reduce the amount used as much as possible and what kind of difference that will make to a company’s bottom line as well as time savings for the operators assembling these parts.
Delving into the past and “back-to-the-basics” Sandy covers ideas long espoused by Dr. Edward Demming and Eliyahu M. Goldratt in the book “The Goal” as well as others. For an aspiring engineering, this episode is a no-nonsense and to-the-point lesson in why having a lean design is key to good product development.
