Siemens

Industrial Placement | Duration: 12 Months | 2017 - 2018

Overview

Between August 2017 and August 2018 I worked within the mechanical drawing office at Siemens Intelligent Traffic Systems (ITS).

Below are some examples of my work during the year. More technical drawings exist but have been omitted to protect the products (in service) as they demonstrate their inner-workings.

Permission to include the following pictures and drawings into a portfolio was requested and received.

Connector Release Tool

Problem Brief:
The traffic signals being released as part of the Plus+ upgrade project contain a module within the body.

On the module there are a row of connectors positions closely together.  The connectors are difficult to remove by hand due to a lack of space within the signal body especially with the presence of cables. There is added difficulty as the work is conducted on top of ladders often in challenging weather conditions.

I was asked to design a tool which would aid field engineers with removing the connectors.

Plus+

The Plus+ project is a redesign of the current traffic management system.

Typically, there a many individual connections between traffic signals (e.g. a Red-Amber-Green traffic light) and the controller cabinet. Within the new system, the individual signals have a dedicated processing unit rather than relying entirely on the controller cabinet (distributed intelligence). The improvements to the system make installation and maintenance easier. Many of the core products are hot-swappable allowing for quick replacement and re-calibration to get the system synchronised. 

For 8 months, I modelled and assembled various 3D CAD models, created dimensioned drawing and assembly drawings. In addition, I prepared installation drawings which instruct field engineers on how to install products on site. Alongside this, I created over 60 BOMs (Bill-of-Materials[) relating to the various products.

Greenpower

Greenpower is a racing competition where people between the ages of 9-25 build single-seater electric racing cars to compete at various venues. The objective is to produce an energy efficient car by taking into consideration factors such as weight and aerodynamics. Siemens is attempting to convert the standard Greenpower kit car into an autonomous vehicle.

Problem Brief:
My task was to design a steering mount to attach a servo motor to the chassis of the car. The purpose of the motor was to operate the steering based on a pre-programmed route. 

In addition, I designed a method of mounting the rear brakes to be operated by another servo motor. Due to the hydraulics of the brakes, the caliper and handle had to be close together.

​European Maintenance Socket

The addition of European mains sockets was requested by a customer to a particular range of the traffic controllers. Traffic controllers are normally supplied with sockets to match plugs used in the UK.

I created a kit of parts to retrofit alongside the existing assembly. For the European controllers, this kit would be wired to the mains power instead of the UK sockets.  The UK sockets will be blanked over using a metal plate to cover the UK sockets.

I created the BOMs (Bill-of-Materials) and drawings for the kit. The kit consisted of a mounting panel which would hold a socket box which would provide Schuko sockets. The kit supplies the necessary cabling to feed into the mains power coming into the controller cabinet and to earth the mounting panel.
