Testing Procedures

          The structure is the component of the filtration system being constructed. This includes the exterior structure and how the filters are supported within the system. Specifications include that the structure must contain the water filtration system. The structure must also be of appropriate size so that the filtration process is not disrupted. The system must also be portable in case space is an issue where the product is being used. The materials the structure is made of must be cost-efficient, durable, strong, and must construct a long lasting product. The system must stand steadily freely. In addition, the system must be able to open so that filters can be cleaned or replaced. Overall, the structure of this water filtration system must house and store both the filtration system and the purified water so that the water can be obtained later on.

            Parts of the structure include the exterior structures (housing, handles, spout) and the interior support for the set of filters. Each of these must be tested in order for the product to function successfully. The housing of the overall structure must be tested to ensure that the product will last a good amount of time (impact resistant); the handles must support the weight of the entire system, and the spout must release clean water that is stored inside. Within the interior, the structure supporting the filters must reinforce the filter system so that when water is being filtered, no failure of structure collapse occurs. All tests will be administered and tested by the designer and team.

            No particular location, condition, or atmosphere is needed. All testing can be done either outside or inside, a hot or cool environment, a sunny or rainy environment. For labeling purposes, all testing will occur outside for spatial purposes so that no messes will result.  

Testing Type: Exploratory
Testing Stage: Preliminary
State of Solution: Drawing
Condition of Testing Stage: Classroom/Home
Tools and Equipment required: pencil, paper, eraser, ruler
Testing Procedures:
1. Select ideas from brainstorming           
2. Sketch out as alternate solutions           
3. Include diagrams/explanations/lab

4. Make sure to include materials and how structure fits together

5. Make inferences on/estimate which materials would produce best results, which overall shape of structure would be most effective, what interior structure would be sturdiest

Alternate Solutions

 

Testing Type: Exploratory
Testing Stage: Secondary
State of Solution: Drawing/Computer made
Condition of Testing Stage: Classroom/Home
Tools and Equipment required: camera, computer
Testing Procedures:
1. Create design matrix skeleton (rows x columns)
2. Take pictures of each individual alternate solution                       
3. Insert pictures of alternate solutions into design matrix

4. Type up specifications and insert into design matrix

5. Rate each alternate solution (select scale) according to how it ranks in reference to specifications

6. Add up total points

7. Determine which solution has highest rank

 Design Matrix

Testing Type: Exploratory
Testing Stage: Tertiary
State of Solution: Stationary Model
Condition of Testing Stage: Classroom/Home
Tools and Equipment required: plastic pretzel container, sharpie, ruler, tin foil, hot glue gun, drill
Testing Procedures:
1. Obtain pretzel container           

2. Using drill, carve out hole from pretzel container for spout of system
3. Plug in hot glue gun           
4. Measure half of container and draw line with sharpie to indicate where filters separate from water storage area

5. Shape tin foil for spout and handles

6. Use hot glue gun to glue spout and handle into place

7. Determine what design aspects could be altered to increase usability of system

 Model

Testing Type: Assessment
Testing Stage: Preliminary
State of Solution: Stationary
Condition of Testing Stage: Outdoors
Tools and Equipment required: external structure of product (complete with spout, handles, lid)
Testing Procedures:
1. Fill container approximately halfway up with water (open lid to ensure proper function)

2. Pick container up by handles to ensure that handles sturdily support overall container filled with water
3. Ensure that spout functions properly by releasing water from container

Testing Type: Assessment
Testing Stage: Secondary
State of Solution: Stationary
Condition of Testing Stage: Indoors/Classroom
Tools and Equipment required: external filtration system structure, internal structure pieces
Testing Procedures:
1. Insert rod into groves bottom of container so rod stands up           
2. Sit base on lip of rod           
3. Make sure all structures fit together to ensure expected performance           

 

Testing Type: Assessment
Testing Stage: Tertiary
State of Solution: Stationary
Condition of Testing Stage: Indoors/Classroom
Tools and Equipment required: Entire structure, filter system (from Rachel)
Testing Procedures:
1. Compile pieces to form entire structure           
2. Insert filtration system (pieces/filters)           
3. Ensure that entire system fits together to produce best performance (interior structure holds up filters)           

Testing Type: Validation
Testing Stage: Preliminary
State of Solution: Fully Assembled
Condition of Testing Stage: Outside (in case any water failure occurs)
Tools and Equipment required: Entire structure, filters, water in need of filtration
Testing Procedures:
1. Put together all structural and filter parts to produce system            
2. Pour water into system           
3. Carry container around to ensure system is easily portable

4. Press on spout to release water

5. Determine how effectively water was filtered (Using Rachel’s water testing procedures)

6. If water filtration failed, open up and take apart system and try to determine source of failure
