- introduce yourself with 3 machines that you would like to make -

[1] - A self-forming mold injection machine
While this machine has the capability to duplicate complex surfaces
through mold injection. In addition, it also has the ability to 
develop the forms needed to output the neccessary geometries. A 
non-developable surface is digitize, the imformation is sent to the 
machine to take the form of the surface. Ball joints, pixel size nodes 
draped over by a smooth fabric take on the form to create the mold and 
the plastic is then injected into the mold.

[systematic organization of ideas]
FR [functional requirements - words] : quickly and rapidly create complex 
          surfaces for architectural analysis...
DP [design parameters - drawings] : digitization of complex forms, analyze 
          the geometries, adjustable ball-bearing joints or micro-size nodes 
          (round needle points), non-stick fabric wrap to create smooth surfaces...
A  [analysis - experiments] : flat-bed with projected nodes (surface area)...
R  [reference - experiments] : 
R  [risk - analysis] : medium to low - re-adapting existing technology 
C  [countermeasures - analysis] : plaster injected modeler


[2] - A fabric cutter
Using the razor cutting technique, this machine is a more efficient 
version of the Roland CAMM-1 paper cutter to not only cut paper and 
vinyl, but also has the ability to cut a variety of fabric materials 
and perhaps even soft plastic. My sister, who is a fashion designer, 
has always mentioned that the worst part of her profession is the 
tedious task of cutting patterns. Designing patterns is the critical 
process and an enjoyable one, but cutting the patterns is a no-brainer 
task but yet it is often extremely difficult to achieve the exact 
duplication of the intended design. This machine will have the 
capabilities to cut patterns and create shapes from developable - and 
perhaps even non-developable surfaces? - out of fabric, rubber, 
plastic or any soft flat materials used in the fashion industry as 
well as in architecture and design.

[systematic organization of ideas]
FR [functional requirements - words] : cut fabric from developable and 
          non-developable surfaces...
DP [design parameters - drawings] : 2-axis roller control, 4-axis rotate-able razor...
A  [analysis - experiments] : large flat surface area for various materials, 
          roller control fabric/material feeder...
R  [reference - experiments] : 
R  [risk - analysis] : low - consideration in regards to power (force) and 
          the strenght of razor's capabilities...
C  [countermeasures - analysis] : modification of CAMM-1, 2-axis control paper cutter...

[3] - A fuse deposition machine for recycle glass
Much like the current laser cutter and the fuse deposition modeler, 
this glass deposition machine has the capabilities to form glass. It 
can work as a glass spitting machine that creates 3-D glass objects by 
melting and forming glass as a base material. Since the properties of 
all glass are similar, this machine may have the potential to take in 
broken glass, melting it and recycle it to make house hold objects.

[systematic organization of ideas]
FR [functional requirements - words] : 3-dimensional glass spitting modeler...
DP [design parameters - drawings] : recycle glass collector, heating/cooling chamber, 
          glass fuse deposition needle,  ventilation, surface bed...
A  [analysis - experiments] : no support materials needed, temperature control 
          requirements, ventilation requirements, surface area's materials...
R  [reference - experiments] : 
R  [risk - analysis] : medium to high - heating (temperature) components to melt glass
C  [countermeasures - analysis] : recycle fuse deposition modeler
