The document summarizes the product development process for a new plant photosynthesis measurement device. It describes the research phase which identified target user groups and competitive devices. Several design concepts were developed with a focus on ergonomics and making the device smaller and easier to hold than competitors. Prototypes and models were created to refine the design. The concept was finalized in CAD files and 3D printed models. Production of the device is scheduled to begin in November 2016.

Design Background – Handoff to Bazza Design
Design parameters to consider for the device:
Cost Sensitive Design
Symmetrical design for no-handedness
Design to minimize light leak
Grip that helps with air flow/heat dissipation
Body color choice needs to be made for light containment (Black vs other colors)
Include some form of wrist attachment (Wiimote)
Design to be hearty/rugged
To have a Cuvette Holder or way to secure one
May need to be water resistant (gasket a consideration)
LED light to show it is in use and or “on”
May incorporate a Beep or Buzz to suggest that the reading is done

Competitive Set
Most devices in this set are clunky
box like designs. Only a few look
like they were given any ergonomic
consideration. Our goal was to
surpass all of these designs in form
and comfort.

Design Inspiration
The examples shown here represent various design to aspire
to be in the case of form, ruggedness and ergonomics.

11. 11-16 11
Design Details
We were focused early on with the fact that some details
may make or break the design. So special emphasis was
going to be given to assembly methods (Screw placement),
rubber covers for the electrical outputs and a proper
attachment for a lanyard .

Concept Development
Research Findings:
Most competition is boxy, ugly, large in size or all three.
The best designs integrate color
The best looking designs are smaller and hand held
Nothing on the market found that looks and works like MSU’s design.
Most designs are “clamp down” or “point and shoot” designs.
It will be easy to design and build something that is functional and
better looking than most products in the market.
Concept Development Next Steps:
Pick Detail Design Directions (rugged, sophisticated, grip details, etc.)
Consider Color
Pick a Lanyard and purchase.
Pick a Rubber Grommet and purchase. Get CAD if it is available.
Start Concept Phase based on Criteria selected.

Concept Development
Where we started from:
Shown is the 3D printed hand built prototype. It was functional but
was basically two blocks screwed together with a living hinge and a
electronic tether. The team at MSU knew that they need to marry the
functions with an ergonomically pleasing design. That is where Bazza
Design came in.

Concept Development
Refinement of the raw components:
MSU personnel refined their mechanical data to a new form factor
that included a vertical jaw like reader area that could consistently
clamp down on a plant leaf. This was the beginnings of Bazza Design’s
from studies.

Form Study Model
A actual size model was made to address overall size and comfort in
the hand. It was determined from this hand build foam model that we
needed to shrink the height a bit and add in the grip details to help
with a comfortable grip. Button location and overall length was
considered good to go. We used the study model to also determine if
we could fit the battery into the back of the design. This was also
confirmed with this model.
