3.3 Product Improvement and Design Documentation

Assign individual responsibilities among team members to complete each of the following tasks:

Based on the concept sketch of the selected solution, create detailed annotated sketches of each part of your design in your notebook. Each group member should review every part drawing to ensure compatibility with other parts and adherence to the approved design scheme. Obtain the signature of each group member on each part sketch to indicate approval of the part.

Create a 3D computer model of your proposed design.

Create a set of CAD working drawings to document your team’s proposed design. The drawing set should include dimensioned part drawings and assembly drawings as necessary. Include all necessary dimensions, material callouts, notes, a parts list, and details necessary to construct

a prototype of the product.

Combined Volume and Surface Area.

Estimate the cost to produce one prototype of your proposed design according to the drawings. The cost should include the cost of materials (including raw materials, fasteners, and purchased components or subassemblies) and labor needed to build the prototype. Although a thorough cost analysis would consider other costs related to taking the product to market (such as manufacturing equipment, distribution, marketing, overhead, and selling the product), we will restrict our analysis to material and manufacturing labor costs.

$50-PELG filament

$300- OKP Roomba

$100- Purifier

$100- Battery Pack

$550- Total

Estimate the time necessary to construct your prototype and an hourly wage for a person to assemble the product. Use these estimates to approximate the total cost of labor to build the prototype.

$15 an hour

100 hours to build a product

$1500 to build for labor

Approximate the production cost for your product by summing the material cost and labor cost.

$2050

CONCLUSION

What other design factors could be considered to improve your team’s design? How would you change your design to achieve this goal?

The use of a more sturdy material in the building of the structure.

Why is it important for every member of the team to be involved in the implementation of design changes?

To gain input and criticism for the overall improvement of the project.

How can a 3D model improve product design? Did your design change as a result of information gained from the 3D model of your product?

It can help improve the design by giving a realistic application to it and no.

How will the cost of production change from your estimate for the cost of a prototype if your product is mass-produced? What factors (in addition to raw materials and labor) will affect production costs?

It would increase due to the number of workers and equipment needed.
