Innovation Management
1. Instructions: Assignment scenario
For the purposes of this assessment you are to assume that you are employed as a project manager at a small engineering company Phase Heat Ltd based in the UK. (This is not a real company, so
please do not try to search for it!)
Phase Heat Ltd have identified an opportunity to develop an advanced hot water heat storage cylinder (HWHSC) for use in the home or small commercial premises. The hot water heat storage cylinder
product will heat and store hot water to be used for showers, baths, sinks and wash basins. The cylinder may be heated by electric immersion heater and/or heat exchange coil (typically connected to
a separate, re-circulating hot water circuit from a boiler or solar thermal panel). Heat loss is reduced by insulating the cylinder with plastic foam on its outside.
The main cylinder design by Phase Heat Ltd has a series of small sealed tubes inside it. Each of these tubes contains a paraffin hydrocarbon that melts at about 60 degrees centigrade. This melting
or
‘phase change’ from solid to liquid takes a large energy input which is available to recover later on as latent heat when the liquid is allowed to solidify. The use of phase change heat storage
within the water cylinder is novel and has the potential to store heat energy when it is available (eg from solar or wind generators) or at low cost (eg using ‘off peak’ electricity tariff,
typically at night time).
The components of the advanced hot water heat storage cylinder (HWHSC) are shown in Table 1.

2. Instructions: Assignment aim and content
The Technical Director of Phase Heat Ltd has asked you to produce a report for the company to explain the proposed innovation development project comprising activities including design, development
and testing of the test rigs and prototypes that will be needed to take the innovation from the current concept through to fully tested prototypes. Phase Heat Ltd would like to start the project on
1 July 2017 and conclude all prototype testing on 1 November 2017.
