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.

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

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.

Problems in the current design arise from a number of difficulties:

Awkward handling

Limited scribe length

Angles are difficult to scribe

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.

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

Combination edge made of a Hard grade plastic.

Ruler constructed out of Steel.

Scribe made out of stainless steel.

Mold the combination edge in a cast

Attach the metal ruler aligned to the center

Attach the sliding scribe to the metal ruler

Finally there are four reasons why it is worth producing this new combination tool:

Cheap to make

Easy to use

Very versatile

Efficient
