Cpdm is very careful to take care of requirements, and sometimes environment restrictions from the surrounding has inwards impact to the outmost black-box (see blog 21). Consequently in such case, the environment restrictions must refined to become the outmost black-box requirement. The environment restrictions 1 to 5 are already taken care of, and the black-box requirements at number 6 are all newly captured, not being refined from anywhere. Requirement 6.E. The electronic expansion equipment must serve all of the existing 12 volt caravan equipment outside the electronic expansion. The solution is proposed, that the fridge is not served via 12 volt, but if a solution is chosen strong enough, there is nothing preventing from also the fridge is feed from the electronic expansion. |
Requirement 6.F. specify an inverter to convert 12 volt DC to 230 volt AC, and there are given proposals on a 300 watt type. Requirement 6.G. There must be a network in the caravan to supply phone charger possibility. A solution is that each bed side table has an outlet for charging phones and tablets. There is a strong requirement 6.H., that it should be possible to play hard rock on high volume through the entire night. There is a solution proposal to use high efficiency loudspeakers and a 2 x 20 watt stereo amplifier for this purpose. |
