Ergonomic Concerns
1. 3. 1.
Wrist angle: Reduce ulnar deviation. Vibration: Shape handle to reduce pressure on median nerve.
2.
Bicep fatigue: provide second handle to distribute load.

Odd angles Cool styling
Strapped to arm Very stable Too heavy for 1 arm
2nd handle for top
Rests on forearm Front hand grip Too long
Parallel handle Stable
Cool aesthetics Bad ergonomics
Perpendicular handle Better ergonomics Easy to carry

Soap Bar Create a form focusing on simple aesthetics and ergonomics that will later be cast in plaster. The plaster casting requires attention to draft angle for the product to succeed. I chose to turn the concept of soap on its head. I created a satire by imposing an unhappy form and feeling to the beauty and softness of soap.

Satire form - screeming face
Satire form - bad ergonomiocs Convex to match body The joke: Smell like death Blend these aesthetics into ergonomic form
Concave to match body

Flashlight The challenge was to create a flashlight geared toward fine aesthetics, and a form that will fit into the contemporary home.

Rectilinear Combine 3 rectangular prisms into 1 form giving each a role among the whole: dominant, subdominant, subordinate. The chalenge is to create an asymetric balance.

Flat Pack Chair Without using secondary fasteners or glue, create a chair that could be assembled without tools. Focus was on making the best use of a 60 x 30 inch piece of plywood. Ambiguity of form and simplicity of parts was my goal. Not furniture. Sculpture.

Too literal
37 Phillip Priolo
Too many pieces Unattractive
Simple: 2 pieces, 1 fold each 2 related forms speak with each other More sculptural, less “furniture�

Heating Tool The project was to redesign a soldering iron focusing on ergonomics. Through research I found a new use for the tool in lost wax casting where ergonimics also plays a large role. I not only focused on hand ergonomics, but also on simplifying tip changes and temperature adjustment.

Research: Range of use
Lost wax casting using a wax extrusion pen. - Like a glue gun - Needs refilling
Traditional soldering for electronic components. - High heat - Typical use/process
Soldering joints for stained glass. - Less precision needed - Cool artistic process
Soldering iron used for lost wax sculpting. - Unique use for tool - Needs temperature control* - Use of multiple tools* * Opportunity to streamline workspace * Feature not available on all tools
Observing class: Lost wax casting phillip.priolo@live.com 44
User Profile Needed tool features - Temperature control - On/Off indicator light - Tool stand - Interchangeable tips - Heated tip storage - Comfort - Precision
- Jewelry maker - Process: Lost wax - 6 - 8 hrs work sessions - Middle age 35 - 55 - Varied interests - same task

Task: Lost wax casting
Roll wax into desired coil size.
Glass work surface.
Tools Used
Use small detail tools to form wax into shape. - scrape - carve - cut - bend Assortment of fine detail tools.
Alcohol burner
The tool is reheated over a burner as it cannot retain heat during the whole process. Melt pieces together to form a solid connection.
A soldering iron is too hot for small detail work, and is only used when adding the sprue before casting. The tip is too bulky for detail work. * Temperature control and changable tips would broaden this tools use throughout the lost wax process.
X-Acto knife.
Soldering iron.
* Opportunity: Reduce tool clutter

Rocket Car Using the techniques from past projects, I created a cartoon style toy car appropriate for a young child. With adult supervision it can be powered by a CO2 cartridge.

SolidWorks Building a bicycle in Solidworks teaches many skills. Surfacing was used to create the frame, while solid bodies make up other components. Adding materials to the surfaces and components adds realism, and putting it all together into a working assembly brings the bike to life.
