PROTOTYPE PRODUCT ENGINEERING-DESIGN
COMPANY: SIEMENS
DIVISION: Energy and Automation
SEGMENT: Custom Controls
SERVICE: Manufacture of "Customized" Control Panels
CUSTOMER: Tokyo Electron
DATE: 1996
NEW PRODUCTS: TEL AC POWER BOX 1 AND 2
POSITION: (INTERIM) PRODUCT ENGINEER
(Project: Tokyo Electron 2) My task was to "Redesign & Respecificy", Two new product lines from Asian to U.S. market standards.
After the departure of my ORIGINAL manager. I explained I was "underutilized" and had the same engineering degree as my supervisor on the Tel Project. They did not realize -"Same school", graduated 1 year apart, same degree. After most engineers found new employment, no other engineer in department wanted to design the new units. They were used to copying my designs for the "Husky" and "Tel" Projects.
I was given this as a task with no assitance . There was more than 300 components per unit. I now had to match a specified foot print as well. Requiring I design the control cabinet to have "multiple stacked subpanels", assure ease of access for repairs, plus address wiring complexity. For these reasons I decided to go "3D". (See side view- on right)
"1st step" was to select the appropriate size cabinet. I then went through the original bill of materials and matched specifications of the components from the Siemens and various catalogs. Resarching specifications "line by line" for matching performance. I then sent my B.O.M. to Tokyo for approval, before I began physical design..
I then redrew the schematics in "Promis-E ADS" to extract a wire list and wires sizes for assemblers to analyze their prospective task. I used promis-e in order to be able to have someone else working on the wire list, so I could later modularize wiring by making "wire harnesses" and "preassembled panels", since each production unit would be identical in the final production.
After I received approval from Tokyo Electron HQ of the "U.S. Market" parts list I submitted . I started modeling each component in 3D, using dimensions from the various catalogs.
In order to Simplfy design, for future use, I customized the Autocad menu system to contain the components and simplify design for the new product lines.
To save time I automated prompting of device IDs. I Made all components and structures to scale. I Built the assembly instructions again around the models.
I then started with 2D layouts of each subpanel, and looking at ideal wire routing to assure ease of assembly.
Next I used the 3D Parts and started a design based on a 3D cabinet enclosure I drew from a catalog speciafcation which matched the desired foot print. (Back then there were no 3D downloads for cabinets), So I had to create my own.
I Then translated my 2D layouts into a 3D model to assure clearances between panels and components fit. I left space for air flow and to eliminate heat retention. Then Designed structural members to assure mechanical ease of access ,operation and repairs.
I then designed the layout using mutliple sub panels. 3D allowed me to examine the panels and components for interferences and obstructions, since the foot print of the panel was very small. I then designed special mounting components and standoffs to assure the correct depth to mate with the door interlock and other mechanically interconnected components.
I then created the B.O.M. and ordered parts working with the purchasing department. I "Q.A." checked incoming parts for accuracy and quality. Supporting the manufacturing floor on the assembly of the 1st prototypes. I worked with the test department to assure functionality during "High potential" testing.
I completed the protoype and created assembly documentation and an "OEM manual" for the customer.
I was then asked to hand the project over to other engineeer who would be the actual engineer now that "I" had designed and completed both prototypes.
.
The Customer thanked me. My managers hired "two" other designers to replace me. They all claimed they could do as well as I.
Another Dept Manager offered me a new job as a "Systems Engineer" seeing how I performed and had little to no support.
Later as other designers made changes and mistakes, I would be summoned from my new position and used to blunt the embarrassment of the newer "team" hired in my place.
I did my job to precison, with "customer appreciation" on every project.
After a many weeks. My new manager told me to "move on" and "no longer support their department". I went to work on HMI and Controls GUI. But ran into similar circumstances as others tried to minimize my contributions as well. By awarding my tasks and trips to other "friends" who were not degreed and got personalized support. (They now are managers). To question my abilty I was then sent to Germany with "no support" to "prove" I could program a HMI, and again prove I was the engineer "I said I was". I completed that as well.
I created tools and standardized production as well as supported manufacturing and addressed customer quality concerns. This was my contribution to revolutionizing production. I had finally been given full Autocad, so I could 3D model in 1996 and also extracted BOM's and streamlined the ordering process. Again often using my tools but given "limited credit". Looking for creativity/ innovation? - "here I am". I give my best. I don't complain. I just seek a real opportunity-fair pay.
I usually "in time" can make things better.
