A New Kind of Scratch: The Dream Team Innovation in Tool Design

This project redesigns a scribe and combination square for efficient and versatile use in material scribing, addressing existing limitations. The methodology involves problem analysis, prototype creation, and plans for manufacturing. Materials used include hard grade plastic, steel, and stainless steel. The ideal procedure includes molding, attaching the ruler, and securing the sliding scribe. The innovative design aims for cheap production, ease of use, versatility, and efficiency.

  1. A new kind of scratch The Dream Team: Sean Keefe, Lucien Filip, Aaron Alves, Manuel Boria, Matt Baxter http://myweb.wit.edu/filipl/Courses/mech163/majorproject.htm

  2. Abstract • We redesigned a scribe and a combination square in order to make it more efficient. • This is more efficient because materials are capable of being scribed at any angle and smoothly. • This new scribe is able to fit pieces that range from one foot to three feet.

  3. Needs Assesment • We assessed the needs of our project based on the following categories: • People- the users interaction with the product • Materials- what the product is constructed of • Machine- how the product is produced • Procedure- how the product is used

  4. Background • While in our manufacturing lab we had to scribe lines on sheet metal for measurements. • Scribing these lines was difficult and consumed too much time and the lines weren’t smooth. • This led to the idea of reconstructing this tool for easier use.

  5. Problem Formulation • Problems in the current design arise from a number of difficulties: • Awkward handling • Limited scribe length • Angles are difficult to scribe

  6. Methodology • First we constructed an ishikawa diagram to analyze the problems of the existing tools. • Then we created a prototype and had rough sketches and autocad diagrams to analyze the features. • Future plans to manufacture the prototype and test it out.

  7. Alternative Solutions • After testing out prototypes the most efficient design of rotating the center piece should be found • This will make the product have maximum range and minimal difficulty to use

  9. Materials To Be Used • Combination edge made of a Hard grade plastic. • Ruler constructed out of Steel. • Scribe made out of stainless steel.

  10. Ideal Procedure • Mold the combination edge in a cast • Attach the metal ruler aligned to the center • Attach the sliding scribe to the metal ruler

  11. Conclusion • Finally there are four reasons why it is worth producing this new combination tool: • Cheap to make • Easy to use • Very versatile • Efficient
