Revisit your design specifications and list the criteria/benchmarks that should be tested to ensure the success of your product.
Roomba Cover
Roomba Side Cover
Air Purifier Halo
Hooks
Pins
Battery Holder
For each criterion that should be tested, determine specifically what you need to know. For example, when testing a lampshade, you will need to know whether the material of the shade can withstand the heat that the lightbulb produces without burning or melting.
Roomba Cover
We can test the component by how the circumference fits on top of the Roomba and if we can still press the power button for the Roomba. It must also perform as a durable base for our air purifier. When the air purifier is put flat on the Roomba cover and still allows for the turning on and off of the Roomba, then the component has given us successful results.
Roomba Side Cover
We can test the component by how it fits the circumference of the side of the Roomba and if it can still filter air, use its sensor, and charge itself. It must also be able to accommodate the hooks that will attach to the air purifier halo. If it allows for the purifier to be stabilized onto the Roomba with the hooks, then the component has given us successful results.
Air Purifier Halo
We can test the component by how it fits the top of the air purifier and how it fits the hooks in the Roomba side cover
Hooks (Upper, Lower)
We can test this component by stress testing them and withstand a certain amount of stress without breaking
Pins
We can test the pins through a stress test, and seeing that they won’t snap before _ pounds
Battery Holder
We can test the battery holder by how it is able to hold the battery and support the hooks.
In your media center or on the internet, look up the ASTM standards for testing of the materials used in your design solution or devices that are similar to yours, if they exist. You may have to contact a testing facility in your area if you do not have access to ASTM books. A manufacturing company or engineering firm that writes test procedures may have the information you need.
As a team, brainstorm the results of your research to determine the parts of your design solution that you will be testing. Your goal is to formulate an appropriate list of test criteria and the method of testing that will objectively measure the effectiveness of your design solution. Consider what type of testing will be performed—qualitative or quantitative? If you have time, it is recommended that you do both. In the case of the lamp shade, if you want to measure the temperature at which the material will burn or melt, you will collect quantitative data, since the temperature is a numeric value. If you want to determine whether the material can withstand a temperature of 350°F for 24 hours without visible signs of burning or combusting, you will collect qualitative data, because the results will be recorded as pass or fail.
Roomba Cover - Qualitatively, observe how stable the purifier is on the Roomba cover.
Roomba Side Cover - Qualitatively, observe how the side cover stabilizes the hooks while still remaining durable.
Air Purifier Halo - Qualitatively, observe how stable and durable the halo is during movement and when the purifier is turned on.
Hooks - Qualitative, observe the hook´s stability and durability during movement while being stabilized by the pins
Pins - Qualitative/, observe the stability and the durability of the pins in the hooks during movement
Battery Holder - Qualitative, observe the stability and the durability of the battery holder during movement
To ensure the successful performance of the design, determine the degree of accuracy that is needed in the data collected during testing. In other words, how close must the measured data value be to the actual value to be acceptable? In the case of the lamp shade, you may be able to accept a deviation of 5 degrees in the measured temperature from the actual temperature at which the material burns or melts. In other words, you have determined that the performance of your product will not be adversely affected if the temperature sensor reads 265 degrees (or 255 degrees) during testing, as long as the actual temperature is 260 degrees.
Roomba Cover - Diameter of Roomba base to the tenth degree
Roomba Side Cover - circumference of Roomba base to the tenth degree
Air Purifier Halo - circumference of air purifier to the tenth degree
Hooks - Can withstand __ lbs without abrasions or snapping
Pins - Can withstand 20 lbs without abrasions or snapping
Battery Holder - the angle of the battery holder to the 10th degree
Criteria/Benchmark
The component must be durable and stable
Description of data needed
Stability of the Roomba and purifier in sync.
Quantitative or qualitative
Qualitative
Degree of accuracy
Stabilization of moving in sync.
Criteria/Benchmark
The component must be able to withstand a certain amount of pounds
Description of data needed
The number of pounds that the pins can resist.
Quantitative or qualitative
Quantitative
Degree of accuracy
10-30 pounds
CONCLUSION
Why is accuracy an important aspect of designing tests?
Because without accuracy defined, or had even, then the tests would have no significance
Why is it important to understand whether you are testing criteria that will yield quantitative or qualitative data?
Because if you don’t define whether your data will be qualitative or quantitative then you won’t know what significance your results will have, or what you are looking for.
