[Feedback] ventilator-concept-sucker-punch
Hi I was hoping to get some feedback on the latest iteration of the "Sucker Punch" concept. As a product designer, my latest creation is always my baby and I need some critical outside perspective. I'll do some quality renderings when it's finished.
Production
- All custom parts are either sheet metal stampings or bar stock cut to length.
- All rods and pipes are the same diameter
- Only M5 and M8 screws
- Design is setup to be equally well made as stampings, laser cuts or CNC milled parts
- Only simple folds which can be equally done on a giant automotive press or a tiny workshop
- Easily available skate board roller
- Widely available 608 Ball bearings
- The separate motor mounting plate can be easily customized to the mounting holes of the used motor
Features:
- Minimal friction on the Ambubag
- The cam track is replaceable when worn out
- A ball bearing reduces wear on the cam track
- Adjustable pump volume
- Very good access to the Ambubag
- Easily taken apart and disinfected
- 12V gear motor which has high torque and can even be run on a car battery for hours or days
Malfunction Behaviour If the concept malfunctions the Ambubag is still fully operational and accessible. An alarm could shrill and a nurse starts hand pumping until the problem is remediated. Concept 8 on the other hand will most likely fail by locking up on the hub-less ball-bearing-less roller. If that happens friction will pull the bag into the machine and possibly rapture it.
