Height is at most 4ft and least is 2ft, the width and length of it should be at most 2ft. The weight restrictions should be between 40 and 60 pounds.
Aesthetics. Are there preferences in the appearance features of the product (color, surface treatment, shape, material)? If so, describe them.
The colors could be white, black, and/or blue. Don’t care about the shape as long as it fits within the parameters.
Materials. Is there a specific material or materials that must be used? If so, describe it.
No there is not.
Safety and Legal Issues. Identify potential safety and legal issues that may arise from the use of this product.
Possibly running into a wall or people. People could possibly try to take it if it is not being watched.
Ergonomics. Identify considerations for the ergonomics of the product.
Could be considered an inconvenience if noise is made or another action that could disrupt the workflow of a company.
Operating Environment. Identify the environmental conditions relevant to the manufacture and use of the product (temperature, corrosion potential, dust or dirt, pressure, humidity, vibration, noise, degree of abuse, others).
Dust and Dirt can be a factor in how it is cleansed from an environment and the rate of how used the air filter will.
Global Environment. Will the product include any toxic or dangerous substances? What is the plan for the disposal of the product at the end of its useful life?
Recycle and renew the product for a new type of product.
Service Life. What is the required service life of the product?
The service life should be at least 2 - 5 years.
Product Life. What is the anticipated length of time that the product will be produced before it is replaced by a newer version or alternate product?
Until the previous product goes out and we can recycle it into a new product.
Durability and Maintenance. Will the product require routine maintenance during its service life? If so, answer the following:
It should not unless it gets dropped or it has gotten something spilled on it. Or somebody tries to reverse engineer our product. Also if some of the motors for the wheels go out.
What specific parts of the product must have easy access for maintenance?
The electronics, wheelbase, and filter.
What is the anticipated maintenance schedule?
When the filter is completely unusable
Are special tools required? How will they be acquired?
No
Will replacement parts be required? How will they be acquired?

As a team, list applicable constraints that the designer must work within. Be specific. In other words, listing “time” as a constraint is not acceptable; you must state specifically how much time is available for the design process.
Budget-due to the limited budget of $110 provided, we must utilize our own money if in need to buy more materials.
Attempt to obtain validation of each criterion and constraint by multiple qualified representatives from each of the following groups: end users, stakeholders, and field experts.
Validation Approved for all criteria by end users(Students), Stakeholders (Engineering Design and Development Teacher), and field experts(Specialized teachers and staff)
Conclusion Questions?
Why is a design brief used in a design process?
To give a preview of what is to come for the design
What is the difference between a design specification and a product specification?
The design shows the parameters before being made into a product allowing for easier modification if needed
Identify at least five constraints that are common to most design problems.
Budge, Time, Materials, Markets, Specifications.
