A distributor in Osaka asked us for 3,000 units of a handheld console case that could survive being thrown into a school backpack by a twelve-year-old, then asked the question that decides the whole project: will the screen be loaded when the case lands on its corner? That question sets the cavity depth, the corner radius and the foam grade, in that order. The first sample came back with 3 mm of clearance over the analogue sticks and a lid pad that pressed nowhere near the display.
Cavity geometry before decoration
Handheld consoles in the 240 by 105 mm footprint class, the size range covered by popular handheld game devices, share one problem: the sticks and shoulder buttons stick up further than anything else in the kit. Supporting the shell on its screen means the cavity has to be cut around the controls, not around the body outline. We scan the device itself, then cut the die-cut EVA cavity so the load lands on the flat back panel and the perimeter. Shells for this job run 0.18-0.22 g/cm3 at about Shore C 60, and the routine drop check is 1.2 m on six faces, three times each.
What goes in besides the console
- Game cards: 8 to 12 moulded slots in a lift-out tray, sized so a card comes out with a fingertip and stays put when the case is shaken
- Cables: a mesh pocket in the lid for the USB-C lead and charger, kept away from the screen side
- Carry: webbing handle or a detachable shoulder strap with a 25 mm webbing, plus a carabiner hook for the outside of a backpack
- Extras: a moulded recess for spare thumb grips, and a wipe-clean lining because these cases get used on trains
Several buyers pair the console shell with a matching earphone case in the same surface material, which keeps the retail set looking like one family. Console shells sit in our game console case range and start at 500 pieces per colourway, with tier pricing at 500, 1000 and 3000 units. Surfaces can be PU leather grain, 600D Oxford cloth laminate or plain matte EVA with a silk-screened logo. Materials are declared to RoHS, REACH and CA Prop 65 with CTI reports against the batch, which is what retail chains ask for before they list a gaming accessory.
The Osaka order is splitting into two colourways, and the second run is waiting on a revised tray that holds ten cards instead of eight. Tooling for the deeper tray goes on the bench this week, and the sample ships with a black matte shell and a strap.
