My industry experience has given me the capability of developing products from concept to production. In support of this I am able to offer these services:
Design using 3D CAD using Solidworks.
Preparing CAD files for part tooling
Preparing drawings and specifications in support of the product parts and assembly
Preparing exploded views, diagrams and explanations for patent applications
Organizing product assemblies using part numbers and preparing Parts Lists
Identifying vendors for producing parts and building assemblies
Soliciting quotations for tooling and part prototypes and production
Following up the preparation and testing of prototypes
Preparing Installation Instructions, Parts Manuals and Service Manuals
Coordinating and overseeing production start-up
I am equipped with Solidworks CAD program and supporting tools.
I also have a base of working relationships with component suppliers and fabrication shops,
some of which are shown on the Links page.
A summary showing my work history and various projects is on the
History page.
In addition to product design and development for industry employers and clients, I've developed BMW performance
products which I market through the
RONGINEER brand.

This housing for an electronic unit was designed from molded plastic.
The circuit board on the left was designed to fit the housing and locate the main mechanical components.
|
|
|
|
 |
This measuring gauge for the quality control inspection of lamp tubes is composed of sheet metal and CNC machined parts.
There are measuring stations for three different length lamps, each measures the length and and of twist of the lamp end caps.
An exploded view of the measuring unit is shown on the left.

DRAWINGS & MANUALS
|
|
In addition to part manufacturing drawings, it is important in the product developement process to prepare assembly drawings
and parts and service manuals. For every product, parts lists are also prepared to itemize parts, part numbers, vendor, cost,
etc.
|
|
 |
This is a typical assembly drawing.
|
|
This is a typical exploded view for a parts manual.
|
|
 |
I've designed wiring systems for vehicles and other equipment, and this is a typical schematic for a engine control
system. It typically takes 3-5 drawings to specify and wire harness.
|
TOOLING, JIGS & FIXTURES
|
|
Designing and preparing tooling is an important part of the manufacturing process. Below are some examples of jigs and
fixtures that I've designed.
|
 |
|
|

ELECTRIC SYSTEM DESIGN & WIRING HARNESSES
|
|
Part of designing and developing vehicles is designing the electric system and wire harnesses. At the outset, apportioning
the circuits for the various components and providing adequate current capacity and fuse protection are determined. Electric
vehicles also require special attention for circuit logic and switching requirements. Below are some examples of wire harnesses
I've designed.
|
 |
|
|
This is the layout board I designed for building the main harness for an electric vehicle.
The completed harness is shown on the right. Fused circuits are provided for the 12V DC power supply, lighting, turn signals
, brake lights, radio, blower and power control.
