<< Back to Home To Next Design Review >>

During the Detailed Design Phase, our team planned to finish up base testing. In addition, we planned on ordering parts required to build a draft bedside table, and lastly, we intended to schedule a meeting with the Industrial Design team to finalize base design.

We were able to place an order and receive materials needed for the project (wood for our table top and casters). Our team met with the Industrial Design team and decided on final design for the base. We were able to update our bill of materials as well.

Test Plans

Purpose

Demonstrate objectively the degree to which the Engineering Requirements are satisfied

Test Plan 1: Ease of Maneuverability (Modified)

Objective: To test two different base configuration with different caster configurations and loads to further our understanding of a final base design.

Needed:

Experiment setup: Each team member will partake in this experiment. Each member will push the two different base models up and down a hallway with different caster configurations. Each of the two bases will be tested with the following setups:

Test Plan 2: Caster Cleanability

Objective: Test casters' resistance to dirty surfaces and the ease of cleaning the caster wheels.

Needed:

Experiment setup: Create a dirty surface over tile. Run the casters through the dirty surface. Document the wheel afterwards. Use a cleaning wipe to clean the wheels. Notate the ease of cleaning and document the wheel after cleaning. Test for:

Test Plan 3: Caster Ease of Maneuverability

Objective: The ease of maneuverability of different casters on tile and the dirt resistance of each material.

Needed:

Experiment setup: Screw in the casters to the sheet of wood. Each member will push the wood plank with the different casters on tile floor. Notate qualitative data.
