Design Project

I. STATEMENT OF WORK

Qualified engineering design teams are invited to submit a technical proposal for the design of a Motorized Automatic Spheroid Storage device to the Department of Engineering at Baylor University, hereafter referred to as the owner. Upon owner approval of the proposed design, the successful engineering team, hereafter referred to as the design team, shall build, test, and evaluate a prototype device. The design team shall then furnish a formal written report and demonstrate the performance of the prototype device to the owner.

The design, construction, testing, and reporting of the Motorized Automatic Spheroid Storage device, hereafter referred to as the device, is a requirement for completion of Engineering 3380 - Engineering Design I at Baylor University for the fall semester 1996.

II. SPECIFICATION

1. Scope

The design team shall design, construct, test, and evaluate a multi-function device. The device shall move two ping pong balls and one golf ball from a recessed platform into a receiving box. The design objectives are to move the balls over the greatest distance as quickly and reliably as possible.

2. Design Requirements

2.1 Design Criteria

The design team shall design the device to meet or exceed all of the criteria listed below.

2.1.a. The device shall meet or exceed all criteria as contained in “ASME Student Design Competition Design Problem - 1996/1997,” appendix A, and all subsequent “Update Bulletins” published by the American Society of Mechanical Engineers.

2.1.b. The device shall not be dangerous to personnel, destructive to Baylor property, or otherwise inappropriate for operation in a classroom at Baylor University as judged by the owners. Special design attention is required to ensure that the device will not function in a manner that could damage the desktop, carpet, or other building furnishings.

2.1.c. The owners may choose to keep the device including all parts needed for assembly and operation for future instructional purposes.

2.2 Design Documentation

The design team shall document the project by use of manuscripts, calculations and drafted drawings. All documents shall be one-sided on either had-written green engineering paper (National Form 42-381 or equal) or laser-printed on 8.5x11” or 11x17” white paper. A formal engineering report is required with drawings and spreadsheet cost figures. Formal oral progress reports are required using at least one overhead transparency and other visual aids as necessary.

3. Safety Requirements

The design team shall conduct all construction and testing with safety as the primary consideration. Failure to observe departmental workplace rules will lead to penalties in performance evaluation.

4. Manufacturing Requirements

4.1 Materials Procurement

The owners shall supply the design team a basic set of tools for construction. Any additional tools and supplies desired by the design team shall be acquired at the design team's expense.

4.2 Identification

a. Nameplates

The design team shall provide nameplate identification on both the storage container and the prototype device, which includes a minimum of the design team name, device name, and team members names in at least 12 point lettering.

b. Warning Labels

The design team shall affix clearly visible warning labels to all components of the device that may pose a safety hazard to operators or observers of the device.

4.3 Clean Up

Cleanliness in the workplace is expected at all times and in all work areas. Failure to observe departmental workplace rules will lead to penalties in performance evaluation. The design team shall clean all work areas with each use.

5. Test Requirements

The entire design team shall test the assembled device during the construction phase to ensure the device is fully operational and within the design specifications of this document. The design team shall assemble and operate the device during the required final acceptance test.

IV. PROJECT DELIVERABLES

The design team shall furnish the following project submittals in accordance with the above contract schedule. The design team should maintain a copy of all submittals for their own use.

1. Conceptual Design

1.1 Conceptual Plans

Free hand plan and elevation sketches of the complete device showing the general arrangement of the device, including estimates of basic dimensions of overall height, width, and depth. The sketches shall clearly identify each of the subsystems.

1.2 Conceptual Specifications

A brief written description of each of the device subsystems and of the device sequence of operation. Each subsystem shall be given a subsystem title by the design team and the narrative shall include the elapsed time estimate, if appropriate, for each subsystem.

2. Preliminary Design I

2.1 Motor Torque-Speed Requirement

An estimate of the operating torque and speed requirement of the motor based on conceptual plans and specifications. Brief qualitative and quantitative (if possible) analysis justifying this estimate.

2.2 Motor Test

A plan for testing the motor to determine experimentally if motor torque-speed requirement can be met. Shall include brief written procedure, sketches of test set-up, and data sheets for recording results.

3. Preliminary Design II

3.1 Assembly Sketches

Orthographic assembly sketch(es) of each subsystem. The drawings shall be drafted using a straight edge and standard engineering drafting and lettering practices, including the use of a standard drawing template and title block, overall dimensions, and notes. All drawings shall be submitted on engineering paper and shall be accomplished in pencil with appropriate line weights.

4. Preliminary Design III

4.1 Subsystem Test

At the preliminary design II progress meeting, the design team and the owners shall identify one subsystem for hardware demonstration at the preliminary design III progress meeting.

5. Preliminary Design IV
