PORTABLE CONCRETE VIBRATOR

Product Development

Project:

Portable Concrete Vibrator

Client:
Bomag, A United Dominion Company, Light Equipment Division
A unique concept for a Concrete Vibrator focused on use/ergonomic and manufacturing efficiency goals. Design includes common flexible molded end caps, common aluminum extruded handles and two piece injection molded housing.  Designed to house 1, 2 and 3 horsepower electric motors and incorporates a quick-disconnect feature for flexible shafts.

Competitive Research
Stow|Bomag’s two existing products, representing a low-cost cast and fabricated metal product, and a higher-end plastic double-insulated version.

Human Factors Research

Preliminary research into Stow|Bomag’s existing product focused on the ergonomics and use of the handle/product configuration.

 Concept Sketches
For the first round of concepts, the client allowed for a “clean sheet of paper” in exploring ergonomics, manufacturing processed, and product usage issues.
As a large number of concepts were produced, triangular shapes demonstrated inherent advantages.
Some of the concepts were about combining a molded plastic housing with metal components.
Other concepts dealt primarily with handle configuration and how this affected ergonomics.

Sketches
The client chose to pursue a triangular form for the product, whose multiple handles address the way the product is used in the field.

This series of sketches explored the many possible ways the selected concept might be constructed.
 
A set of common endcaps spanned by handles further defined the design.
CAD Development
These CAD drawings formalized the hand sketches, illustrating construction details of the three final directions.
Mockup
A wood and plastic mockup of the selected construction direction best illustrated form, scale, and the assembly of different components.
3D Modeling
Three final design proposals were modeled and rendered for better visualization.

Design Refinement
With the final design direction selected, development began into the details, switch locations, venting, and controls.
2D CAD Drawings
The details worked out, CAD documents and models were prepared to support the rapid prototyping process.
3D Parametric Modeling
ProEngineer models were used for the rapid prototyping process and for engineering evaluation.

Moldflow Analysis
Outsourced moldflow analysis of one of the major injection molded parts helped to identify potential problems in the part's design before committing to expensive tooling.

Stereolithography
Stereolithography models were created from 3D data files to test fit and assembly of the components, including the internal motor.
