1. The New Chicken Feeder By Revanth Damerla

2. What I Wanted to Make When I looked at the chickens, I saw that they got a large amount of their food from a special chicken feeder. I saw a lot of problems with the old feeder and wanted to change it to make it better for the chickens and make it easier for the workers as well.

3. The Problems Food got wet Food got dirty Too much cleaning Large mess and spillage around the feeder

4. What Are Chickens Like? Will not eat themselves fat Can’t fly well Aggressive Have the ability to learn Learn best when they are young Observant Eat small-sized pellets and eat little food Not smart??

5. Functional Requirements Keeps food from getting wet Feeds chickens when needed Minimizes cleaning Robust Waterproof Reloads automatically so people don’t have to watch it Doesn’t use electricity Works with chickens of all types, weights, and ages Uses their possible stupidity

6. The First Design Used gears to operate a lever to bring food out Stored in a large tower Automatic reloading No electricity Easy to use

7. First Design FRDPARRC Functional Requirements Design Parameters AnalysisReferencesRisk Counter- Measures Keeps food from getting wetIn a large tube Simulating food with LEGO pieces Old chicken feeder Feeds chickens when needed Step on the lever Studying the chickens in the backyard Chickens in the backyard Chickens will get at food Tower too tall for chickens and food covered Minimizes cleaning Only have to clean occasionally RobustAll screwed in WaterproofLid on top Takes up too much space and wood ? Reloads automatically so people don’t have to watch it Spring systemWon’t reload Gears mesh to allow piece to slide back Doesn’t use electricity Completely mechanical Works with chickens of all types, weights, and ages ? Spring broken or falls Spring is strong and covered Uses their possible stupidity Can’t force them to use it Chickens won’t understand ?

8. The Next Prototype: How it Works

9. FRDPARRC (And Why I Chose It) Functional Requirements Design Parameters AnalysisReferencesRisk Counter- Measures Keeps food from getting wet Food kept in large holding tank Observing chicken activity in backyard Old chicken feeder Takes up too much space and wood Compact box Feeds chickens when needed Releases food in holding tank when on lever Seeing if spring will stretch with added weight Chickens in the backyard Chickens will get at food Top latched and extra food in box Minimizes cleaning Only need to clean small pan Seeing if food will slide at angle Chicken feed Robust Uses wood that lasts a while, long screws McMaster-Carr Waterproof Lid on top, no decompose Hooke’s Law Reloads automatically so people don’t have to watch it Spring system, weights on trigger Won’t reload Put more weight on front of trigger Doesn’t use electricity Completely mechanical Works with chickens of all types, weights, and ages Small spring constant Spring broken or falls Put covering and spring is already strong Uses their possible stupidity Only way to get food is up lever Chickens won’t understand Show them going up box=food

13. Analysis Does the Spring Stretch Out?Watch the Chickens F=kx 5.5 lbs=1.57 lbs/inch(x) x=3.5 inches

14. Testing!! What it Looked LikeThe Results Began the integration process to teach the chickens that the box and going up the lever means food. Chickens are getting used to the lever going down as they walk up. They have figured out where the food comes out

15. What I Would Change Not waste as much space by creating a more efficient funneling system Make a better system to get the chickens out Stores more food so it will last longer without humans needing to operate it

16. What I Learned Engineering Design Process Use your notebook and label properly. Make sure everyone can understand everything. Occam’s Razor Saint-Venant’s Principle Abbe’s Principle Leadscrews Different types of linkages Think of possible problems before building.
