Watch the video to learn how to make a list of product requirements.
In the space below, record the Product Requirements for a possible solution.
Product requirements define and often quantify what must be met in order for the product to be successful. Each design requirement should be testable. The product requirements should be changed and updated as new information is gathered from the clinical mentor as well as through secondary research.
The Product Requirements list must include the following requirements:
Material selection: The solution must be comprised of materials which are available locally in Nigeria
Due date: A prototyped solution must be delivered at the end of the design process
See an example of some product requirements below.
See below for a list of some example product requirements for the design of a device which must continuously monitor an infant's body temperature and alert a caregiver when the infant is hyper or hypothermic.
Temperature Measurement Accuracy: ±0.3°C
Time to Indicate Accurate Temperature: < 90 seconds
Alarm: A caregiver is alerted when the patient's body temperature falls below 36.5°C or rises above 37.5°C
Patient Interface: Interface is biocompatible and reusable
Size: Small footprint, portable and can be left at patient bedside
Weight: <100g
Decontamination: Can be cleaned with common disinfecting agents
Patient type: Neonates born at any gestational age
Material selection: The solution must be comprised of materials which are easily accessible in local markets
Operating Environment: Hospital or clinic setting in a low-resource setting with dusty conditions and variable access to electricity
Ease of Maintenance: All parts must be easily replaced with spare parts available at the local market
Note: You'll notice in the product requirements for the infant temperature monitor that there is no specific requirement that the thermometer is an infrared sensor or a thermocouple (two types of thermometer). You'll also notice that the caregiver must be alerted, but there is no indication of how the caregiver is alerted. Maybe the caregiver receives an SMS, or maybe a light will blink on the device or a buzzer will sound. Choosing how to meet the product requirements is up to the design team to solve in the idea generation phase.
