Technological System Parts
All technological systems include these parts.
The input of a technological system can be electricity or a user-defined setting. The clock has an input that lets you turn it on or off, while the toaster has an input that allows you to change how long to toast your bread for.
All technological systems also transform the input. They do work on the input to give you what you need. For example, the clock takes the on input and transforms it into time, while the toaster transforms your request into heating your bread for the amount of time you have requested.
After the technological system has transformed the input, it gives you the output or outcome. For the clock, you see the time, and for the toaster, you get your nicely toasted bread.
To make sure that the technological system is working, there is usually a control. This control is how the technological system should work. For the clock, it will be a working clock that is accurate, and for the toaster, it will be a working toaster that toasts the bread correctly. If a technological system doesn't work like the control, then something is wrong. For example, if you get a toaster that always burns your toast black, then that's a system that's not working properly.
A technological system can also have various subsystems. Take your smartphone, for example. It has a camera, various apps, a touchscreen, a light, a vibration setting, and a speaker. These are all subsystems that are technological systems themselves.
Creating a Technological System
Technological systems are created by people to meet a need. It takes a lot of teamwork to create a technological system. You have your designers and engineers that create the product, and then you have other people to test the product to make sure it works properly. You also have people that come and fix or repair technological systems that are broken or are otherwise not working as they're supposed to.
The creation of a technological system typically goes like this:
Technological System: Example
Let's explore an example of the creation of a technological system: a doorbell. Almost every house has a doorbell. It is a technological system because with the input of a push on the button, an output occurs in the form of a bell sound inside the house.The doorbell meets a human need: to know when someone is outside the door and needs attention. Researchers designed the doorbell so that the end with the button is on the outside of the house, and the bell is inside of the house. Engineers used the researchers' design to build the doorbell. The doorbell has been tested. Consumers have evaluated the doorbell; it is in use almost everywhere. This technological system is seeing a gradual modification to something more high-end. You now have camera doorbells that allow you to see who is at the door before you open it. In fact, some of these high-end doorbells even let you speak to the person outside the door even if you're not home. Yes, some of these are connected with your smartphone, so people will never know you're not there even if you're on vacation on the other side of the sea. This shows how a technological system can be modified over time to suit changing needs.
All right, let's review. As we learned, a technological system is defined as a system that takes an input, changes it according to the system's use and then produces an outcome.
A technological system includes these things:Input Transformation Output Control
Finally, we learned that the creation of a technological system typically goes like this:Someone needs something. Researchers design a solution. Engineers help build a solutions. Technological system is tested. More people evaluate the product to see if it works. System is modified or abandoned as needs change.
