FK Action Project for Design & Engineering " Project Garret"

-


We just wrapped up our first unit in Design & Engineering. This unit was about simple machines and the basis for almost every tool in the modern day. We also discussed the design process and how important empathy and understanding the audience that you're designing for. Empathy is understanding someone else's situation and/or emotions. It relates to this project because we need to understand what it is like to be an elderly gardener before we can help them. This project is asking me to work on a design with my partner that could assist an elderly gardener with simple gardening tasks that may be difficult with old age. The eldery user I had in mind well designsing my tool was a person with back pain or a person who wants to cut roots and also scooping soil. It is called project Garret. 

To get a sense of empathy I interviewed a local gardener. During my interview the local gardener said "Due to my CRPS, bending and being on my knees is very difficult." So I made my design acommadate a gardener who cannot bend down or work on their hands and knees. 


This is my original design: 


I have made many changes to it since this design. I like adding a bipod, and making the blades motorized. 


This is a story board of my design and it being used: 





This is the shovel being properly stored in a shed.





This is the elderly person getting a shovel.






This is the shovel being used on the surface.






This is the shovel cutting the weeds and roots under the soil.






This is the elderly person cleaning the blade with a hose






This is the elderly person putting the shovel back in the shed.

 Project Garrett is significantly more efficient than other shovels on the market because they have a motor that allows more soil to be shoveled even by an able bodied person.  Garrett also eliminates a lot of fatigue when shoveling due to the bypod elimanating back engagment. Garret is just better. 

These are the input and output forces of my design: 





This is the volume and surface area of the spinning blades:





These blades are wedges. A wedge is a simple machine that has most of it's mass at one end and less at the other, the mass gradualty gets lower and lower till it reaches a flat point allowing for a large amount of force applied to a smaller surface area. 

B = 0.5 inches



H = 1.5 inches


W = 1/16


V: 1.5 • 0.5 • 0.5 * 1/16  = 0.0234375 in^3 


SA:


½(1.5 × 0.5) × 2 = 2.375


1.5 x 1/16 = 0.09375


0.5 × 1/16 = 0.03125


H × 1/16 = 0.0988211769

sum of = 2.5988211769 in^2

The Manlet Bridge

-
Hello Reader, This was our 1st unit of Urban Planning called "Load". During this unit, we focused on truss bridges and their mathematical concepts, using only 75 popsicle sticks and glue to build bridges that could support 10 lbs and span a minimum of 18 inches. The bridge designs were completely up to us, and we were encouraged to be creative. This project mirrored the work of Mark Bennett, an urban planner for Chicago who has to work within resource constraints. Our efforts gave us better understanding of the dynamics of bridge engineering and how to apply mathematical concepts to our designs. Furthermore, we gained insight into the challenges faced by urban planners, who must successfully balance design creativity with material limitations engineering requirements. My bridge is called "The Manlet Bridge" because of it's size. The bridge that inspired the Manlet Bridge was the Somerset Bridge because it is the narrowest bridge at just 56cm wide. In order to ac...

Miguel's Bike

Hello reader! This is my action project for Design & Engineering unit 2. This unit I learned about the design process, gears, circles, ellipses, the ethics of design, gear ratios, and much more. This unit we went on a lot of great FE's but the FE to Dyson was really great in my opinion because we got to work WITH design not just have them talk to us then us doing nothing with it. Something I am very proud of this unit is my interview because I put a lot of work in to it. For this project I was given a persona to design a bike for based off the situation the person is in. The purpose of this project is to use all the information we have learned this unit on a real world problem being solved by others around the world but in our own GCE kind of way. Persona: Meet Miquel Location: Sitges, Spain Age: 12 Distance from school: 1.5 miles SITUATION Sitges is a small coastal town on the water, but it’s also full of tourists - meaning Miguel has to worry about vandalism when they lock ...

FK Action Project For "Food Class" Unit 3 "GMO's"

  GMO’s. Ok ok, before you think I’m some hippie who’s here to tell you how awful GMO’s are I’m actually here to tell you the opposite and i believe they are totally fine. But first some background info. I am a student at GCE lab school, this is my action project for my 3rd term of food class. During this class we discussed a man named Norman Borlaug. Norman Borlaug was an american scientist who introduced new, disease-free wheat to India and solved hunger there. Thanks to Norman Borlaug Morocco has much better yields of wheat.  During this class we also discussed probability for a little bit, and connecting it to Punnett squares. We also discussed plant reproduction, such as the parts of male and female plants like the stigma, and the stamen. We also went on a field experience to a farmers market and discussed different types of foods with the farmers and  had interesting conversations with them. It was also a blast having lunch with the class.  Now getting to the p...
