Final answer:
MUST NOT constraints indicate limitations on a design, such as safety or legal requirements, while MUST COVER constraints are requirements that the design must include or meet to be functional or compliant.
Step-by-step explanation:
In the context of engineering design, the terms MUST NOT and MUST COVER relate to the types of constraints that a design team needs to consider when developing a solution to a problem. The MUST NOT constraints refer to the limitations set on the design that indicate what aspects the product absolutely cannot possess or operations it cannot perform. These may include limitations due to safety, legal requirements, or physical impossibilities. On the other hand, the MUST COVER constraints are those requirements that the design must include or meet to ensure the product is functional, complies with regulations, or satisfies user needs.
