Project Overview

• Automated system making the shelves in a standard
  kitchen cabinet easily accessible
• The system will be motorized

• Improvement upon existing designs
• Incorporation of customer needs

Overview Contd
4
Time Management

• The group meets Mondays, Tuesdays and Thursdays
  to continue work on the fabrication of the unit
• Also meet with our advisor Tuesday afternoons

5
Product Design

• The Cabinet
• 15 inches high
• 9 inches wide
• 6 inches deep
• The Guide Arms
• 1 by 8 by ½
• Inside Arm
• 1 by 7.5 by ½
• The Actuator
• 6 inch stroke

6
Scale Down Model

• We chose to use a half-scale model
• Will still give a good idea of full-scale motion
• More economically feasible
• Makes product portability
• Can be taken and shown at presentations

7
Scale Down Model Contd

• Still need to calculate actual loading
• Half-scale means one eighth total volume
• Interior volume is actually less
• Determined 20 pounds of total loading
• Equates to 67 pounds of pull needed by actuator
  Friction losses included
• Chosen actuator can put up to 110lbs

8
Building Focus

• Sturdy frame
• Ease of movement for arms
• Minimize wobbling
• Use of spacers
• Smooth and controlled movement of cabinet
• Alignment of holes and brackets
• Accurate fabrication of metal parts

9
Building Objective

• Build a half scale model of the assembly
• Small enough to transport to presentations
• Implement safety features
• Complete model two weeks prior to Senior Design
  Day
• Adequate time for testing
• Model should be accurate representation of full
  scale design

10
Building Progress

• Parts have been ordered and received
• Fabrication has been done
• Arms
• Plates
• Assembly
• Frame
• Whole unit

11
Ordered Parts
12
Fabrication Plan

• Machined Pieces
• - Arms and plates are made from Aluminum
  Alloy 6061 ordered from McMaster-Carr
• - Drawings were reviewed by advisor and
  parts were machined in the machine shop

13
Fabrication Plan - Frame

• Frame / Wall
• Frame simulates a kitchen wall
• Main reason for a scaled-down prototype
• The wall is 36 high and 12 wide
• Made using 2 x 4s, plywood, mending plates, and
  screws

14
Building Process - Cabinet

• Cabinet
• Made of red Oakwood
• In scaled down dimensions
• Hinges and door handle attached to door
• Magnet to be attached in interior to keep door
  closed

15
Assembly

• Frame is assembled
• Cabinet is built
• Plate has been screwed into cabinet
• Arms have been fitted to brackets with washers
• Assembly will be done by next week

16
Tests to Run

• Strength Test
• Lateral stiffness
• Actuator capacity
• Controls Test
• Momentary switch
• Sensor Test
• Limit switch
• Obstacle sensor

17
Problems Anticipated

• Difficultly scaling down linear actuator and
  brackets
• Programming of sensors
• Integrating all parts
• Even alignment of arms
• Reduction of friction in joints

18
Goals to be Achieved

• By Senior Design Day
• All parts will be assembled
• Programming of sensors and actuator will be
  completed
• Poster for presentation will be ready
• Prepared to explain project and take questions
• Fully functional scale down model
