History The first remote came from Zenith in 1952 and was connected to the TV with a cord The second popular remote design was a flashlight. The third generation of remotes used ultrasonic waves that could be heard by dogs.

How it Works Modern day infrared TV remotes have manual inputs (buttons) that have matching binary codes for each function. This code is transmitted to the TV by a non-visible infrared light source and translated by the TV.

Mechanical Engineering Considerations Fitment of the components i.e. Batteries and ease of changing batteries. Safety considerations i.e. Small parts, choking hazard.

Electrical Engineering Considerations The majority of the TV remote is electrical. Battery power is used to create a signal to perform the desired function. Printed circuit board links buttons to the chip. The chip is linked to the infrared bulb.

Industrial Engineering Considerations Low cost materials such as plastic lower production costs. Outer casing snaps together for easier assembly. Many aspects of production can be automated Many units can be produced in a short time.

Conclusion The modern TV remote is a prime example of how all of the engineering disciplines play into how a product is made and how it functions. Improvements could be made to size (larger or smaller) Improvements could be made to battery size or lifespan.
