For our Keen Machines Project, we made a plant waterer for Mr. Lemley as he was in need of a plant waterer during the vacations. The purpose of our machine was to water plants in the library when the school is closed and Mr. Lemley is not there. The mechanism of the machine was based on the Shishi odoshi and our machine used a first class lever.
|Idea No.||Person or Group||Location||Task||Solution|
|1||Mr. Lemley||Library||Water Plant||Plant Waterer|
|2||Soccer Managers||In front of storage place||Make moving the cart easier||Slope|
|3||All people||Door next to doctor’s office||Open door||Swipe Card|
|4||All people||Cafeteria||Make it easier for people to move/ fold tables||Better wheel/ hinges|
We brainstormed several potential ideas but we decided to make the plant waterer as unlike ideas 3 and 4, we had a specific client; Mr. Lemley and he was in need of a plant waterer during the vacations and suggested the idea. He was an ideal client as we could easily contact him and discuss details with him. We chose to do the plant waterer instead of the slope as despite the plant waterer having a bit more complex mechanism than the slope, we had a clear idea as to how the machine would work and the simple machine we were going to use. Also, we knew for sure that we would be able to calculate the Actual/ Ideal Mechanical Advantage, Input/ Output Work, Efficiency as the machine used a first class lever. The plant waterer also used affordable materials and did not require carpenting skills that were beyond our/ Mr. Mayhew’s ability.
How did you develop a relationship with your client? *
We contacted our client through e-mailing and physically talking with him regularly.
Below are the details of dates of contact, topic discussed etc.
|March 9th 2016||Mr. Lemley looked at the machine in action at the Keen Machines Event and he gave us feedback later on.
Explain how you designed your solution. *
The mechanism of the machine was based on the Shishi Odoshi and our machine used a first class lever. We used wood for the base and side supporters and back stopper, and used bamboo for the lever and fulcrum.
Below is how the machine works:
- Put the amount of water the plant needs for the number of days the client is gone, inside the bucket.
- Put the plant under where the water will come out.
- One of the two openings in the air control valve should be closed so as not to leak the water. The open valve should be fitted into the water irrigation pipe.
- Place the water irrigation pipe on top of the receiving opening of the bamboo lever so the water will drip from the pipe.
- To start the watering, loosen the valve so the water will start dripping.
- When the water accumulates inside the bamboo lever and crosses the point where the fulcrum is, the lever will tilt enough so as to pour the accumulated water onto the plant.
The amount of water flow from the pipe onto the receiving opening of the bamboo lever can be adjusted by turning the valve.
- Explain how your learning in the sciences and design complemented each other. *
By learning the physics and science behind the mechanism of machines, it enabled us to form an idea of how we could use simple machines to build machine that could solve our client’s problem; watering the plant when he was on vacation, in design.
Explain the new things you learned about the subjects while carrying out the project. *
I definitely learned more about the physics and science behind the mechanism of machines and how machines can make work easier for the client and do something that could not have been done otherwise.
Project Question: How did you use empathy and your understanding of mechanics (science) and ergonomics (design) to help create a solution to an authentic problem? *
By incorporating our understanding of physics and science behind simple machines and our woodworking and carpentry skills, we were able to successfully make a plant waterer for Mr. Lemley, our client.
Identify which three (3) Approaches to Learning skills you developed and practiced through this project. *
- Reflective Skills
- Critical Thinking
