2017-2018 The Engineering Design Category Problem:
The task for the Engineering Design Category is to create a functional design of a step pocket of folding/sliding step and insert for the rear bumper of a mid-size pickup truck to assist entry into the truck bed when the tailgate is in the down position. A CAD model of a portion of a rear bumper will is provided as a Creo .prt and .asm
format to work from along with a pdf image that shows the bumper in context. The
student will begin with this CAD model to build your design with any CAD program
your school is using.
Parts: ASBE Truck Step Files.zip
Model Criteria
- The step pocket or or folding/sliding step must be accessible with the tailgate in the down position.
- The design is to include a step pocket insert which is to be made out of a nonslip, non-metallic material.
- The bumper can be modified as necessary without changing the overall
dimensions.
- Only the left (driver’s) side step pocket is to be designed.
- No part of the design can be lower than the lowest point on the bumper when the tailgate is in the up position (Vehicle is moving)
- All attaching methods and fasteners should be clearly shown.
The design of the step pocket or insert must not include the name of the
student, school, school logo, or otherwise identify the student, school, or the
school district.
- Each part of the step pocket and pocket insert must be shown in orthographic
projection using at least two views; section, auxiliary; iso views can be used as
needed to fully describe the step pocket and insert to clearly show how they fit
together and are assembled.
- Each component of the design must be labeled with part name and material.
- Fasteners and other such devices must also be shown in their proper
assembled position.

- Title Block: Download from Engineering Website > Engineering Applications > ASBE. The entry is to be identified with a title block that is included with the Contest materials under two file formats for your choosing. This “Student Information Block” is to be printed on, or attached to the lower right hand corner of the sheet, or printed and attached to physical models. Enter the information
requested including the student proper first and last name. Please do not
change the scale of the Block; it should appear 3.5” x 3.5” on the drawing. No
other title block or identifier should be used. Student and school information will
