‘Looks-like’ Model Prototype: Simple, inexpensive, quick, surrogate materials Purpose: Helps us with what the device will look like in terms of size and shape + communicate what we’re trying to achieve Problem Solution 1º Contacts Planning Instructions Prototype 1 Selection
Height Measurement Thin PPPS plastic was chosen for it’s adoptability and ease of replacement. CAD Depiction Ideation + Concept We expect the measuring tape to pulled, bent, strained and under tension. The material should be: • water proof 7 • smooth to ensure easy rolling-up • Insulated so as not to warm up and hurt the baby during the summer • Maybe an antibacterial coating Problem Solution 1º Contacts Planning Instructions Prototype 1 Selection
Weight Measurement LED signal was chosen because it is easy to understand. We expect the LED screen, button and fingerprint scanner to be pushed. The components should be: Load cells • Water proof 7 Power supply – alkaline batteries • Easy to use + understand 3 LCD display • Insulated Microprocessor • Potentially sealed with Green and Red LED light antibacterial coating Adafruit Fingerprint Sensor Problem Solution 1º Contacts Planning Instructions Prototype 1 Selection
Data Collection SIM card was chosen for it’s versatility . We expect the SIM card to be pushed and pulled. The casing should be: • Water sealed 7 • Easy to use 3 Problem Solution 1º Contacts Planning Instructions Prototype 1 Selection
Packaging Plastic - PPPS with roughness on the top was chosen because it is readily available and inexpensive. We expect the scale to be under strain, tension, compression and potentially dropped. The components should be: • Chemically inert • water proof 7 • Rough to hold the baby but not harm the baby • Insulated so as not to warm up and hurt the baby during the summer 7 • Easy to sterilize Problem Solution 1º Contacts Planning Instructions Prototype 1 Selection

Weight Measurement Tapes vs Scalable Solutions Weight Tapes 8 Scalable Solutions ■ Capital equipment product ■ Reusable Product ■ The product will function as ■ It’s not technically feasible designed and user error will ■ Customers will adopt and use determine whether or not the product they function as designed ■ May not be patentable ■ The innovation is novel and because the novelty stems unobvious and has the from combining functionalities and there is not apparent potential for patenting obviousness ■ Easier to use ■ More precise ■ Less training for the technician ■ Versatile
Next Steps for Works-Like Model Does it hold the baby while Can it be charged? the baby is moving? Does it accurately measure Is it user friendly? the weight? Does it store the height and weight measurements with Ergonomics/grip/weight the fingerprint ID? FROM THESE MODELS: Define more detailed design requirements and tech specs (see below)
