Design Problem & Design BriefDesign Problem & Design Brief Design Problem

Heat stroke Third leading cause of death among athletes in the United States.

Overexertion in conditions of high temperature and high humidity increases heart rate to unsafe ranges and prevents the body from effectively dissipating heat.

Exhaustion and cramps caused by overheating are common problems in athletes

Hyperthermia Thermoregulatory mechanisms become overwhelmed and fail, possibly leading to organ damage or death.

Symptoms: Seizures, disorientation, confusion, unconsciousness, coma

Design Brief Athletes and trainers need a device to monitor temperature and heart

rate A wireless device to be conveniently and comfortably worn on the body

during athletic activity. A receiver that processes the data and alerts user to stop activity when

temperature and/or heart rate deviates from safe range.

Specifications and ConstraintsSpecifications and Constraints• Measures BOTH heart rate and body

temperature, allows for prediction of heat exhaustion, not just a training tool.

• Wireless technology ensures portability of device.

• The device must be comfortable to wear so as to not hinder athletic performance.

• Accuracy of measurements is essential to prevent fatality and unnecessary withdrawal from athletic events.

• The cost to buy the device must be minimized so that school athletic programs can afford it.

Specifications and ConstraintsSpecifications and Constraints• Will be water resistant to prevent electric

shock.

• Battery life will be sufficient to power device through the length of athletic events.

• Temperature and heart rate measurements will be easily readable by the user/trainer and equipped with an alarm for when unsafe levels are reached.

• Customer: Athletic departments, e.g. college level and below

• User: Athletes of organized sports, e.g. football and cross country
