Final Design
Project Brief:
Omega Medical needed to “spruce up” a
concept they had for a women’s medical
biopsy devise. The mechanical concept was
figured out and protected with patents but the
device shape and features were considered too
generic looking and not ergonomically
appropriate for both left and right handed
doctors. Bazza Design was asked to look into
creating a more suitable shape that would fit
the hand comfortably, not be “handed”, would
be able to perform the procedure in multiple
ways and have a softer, friendlier medical
looking form. Bazza Design also was tasked
with creating 3D CAID for the final form and
oversaw the creation of prototype models.
The design concepts were shown to a
collective of doctors which in turn gave vital
feedback at check points in the design process.
The end result (pictured right) is currently in
production.

Competitive Set
More attractive shapes.
Very Mechanical
and not at all
attractive.

4. Case Study: Hand Held Medical Device
Research
Competitive Set
“Gun” shape has
threatening look.
These have the
Frankenstein feel
“Syringe” shapes
have a scary
connotation.
Again – looks too
mechanical.

Research
The Mechanical Concept in prototype form
Top trigger button and side safety switch need to have a
more highly integrated presence and a focus on nonhandedness.
Form is generic “torpedo” shape with small buttons that
do not integrate well with the form. Back button
provides an alternate way to trigger the device. Form of
the back button needs to me more integrated and solid
feeling to the body (design is too wobbly.

Form Studies
Considerations:
- Overall size
- Grip form
- Two shot for soft touch grip
- Buttons placement
- Buttons size
- Form friendliness
- Part lines

11. Case Study: Hand Held Medical Device
Refinement of Design
New sketch variations based on doctors
input from previous work.
Chosen design to move ahead into final 3D.
Integration of buttons with form makes for
logical placement of the buttons. Button
shape and size works with the natural
placement of the thumb and index finger to
release the safety and trigger the
procedure.

Final 3D Design Modeling

Hand Held Prototype Creation
Clay Modeling for surface prove out and casting of
shapes. All models were created by Bob Bly of
Robert Bly Design.

14. Case Study: Hand Held Medical Device
Hand Held Prototype Creation
Safety’s were located on both sides of the design for
left and right handed use.
Final hand built prototype used for sign off on the
shape, form, feel and placement of the
buttons/safety latches.
Back button was located for “alternate usage” position of
the hand.
