Illuminated Tablet Marker System
A hand held device that ejects illuminated tablets to mark out a safe route in emergency or military scenarios.
Duku were approached with the problem of how to store, activate and eject a specially designed tablet that can be illuminated to mark out a safe path. Initial concept work focused on how to create a simple and ergonomic handheld device that would perform reliably in extreme environments. The proposed concept uses a similar arrangement to a stapler, whereby a sprung section is pushed down to eject the item in question. In addition, the device needed to provide easily replaceable cartridges, each holding 10 tabs.
CAD & PROTOTYPING
A CAD development stage focused on detailed development of the mechanism used to eject and activate the tablets. This was a particularly tricky mechanism to develop, as it required critical interaction between a metalised rubber ejection pad, and the top part of the tablet, to ensure the tablet was activated and illuminated before being ejected from the casing. In addition, the replaceable cartridge was developed with a focus on holding the tabs securely and uniformly to ensure reliable ejection. A sprung release mechanism was integrated into the dispenser to ensure that the cartridge was clipped in securely, and could be easily ejected at the push of a button. Pushing the release clip down would release the 10 tab cartridge, allowing it to spring outwards so it could be easily grabbed by the user.
Following extensive refinement during the prototyping stage, the CAD was finalised for manufacture, and a full production specification was created. Duku then assisted with the tooling and manufacture of an initial low volume production run.
