Rearview Mirror Design
MAKcad was given the task to design an exterior rearview mirror, powered and heated, for trucks and transit buses.
The product design constraints were:
+ 10x10 inches size
+ Chassis / cowling style
+ 12V or 24V actuators
+ 12V or 24V heated glass mirror
+ Quick parts replacement by customer
+ Parts able to be used for future 15x8 inches mirror version
+ Low profile depth around 3/4" to 1-1/4" diameter arm
MAKcad design plan and execution:
+ FMVSS and CMVSS regulations studied for compliance
+ Top down design methodology (global profile drove specifics)
+ Chose Magna actuator (because of reliability and availability)
+ Got 3D CAD actuator file from Magna
+ Sketched overall 2D parametric mirror profile around actuator
+ Sketched chassis, mount, and arm profiles around actuator
+ Tweaked then made rough 3D models based on profiles
+ Defined component materials/process then refined models
+ Added tweaks based on depth, weight, FEA, and simulation checks
+ Rapid prototyped parts and presented to client for approval
The product has now been successfully in the market for 7 years !
