The Engineering Design Process Worksheet



Engineering Design Process ( Summary Worksheet

| | |Identify the underlying need fully and abstractly (without implying a solution). |

|1. Needs |Problem Statement: |> |

|Analysis: | | |

| | |Make calculations based on estimates, to further understand the problem and its feasibility. |

| |Order of Magnitude Calcs: |> |

| | |Identify properties the design solution must have. |

| |Requirements: |> |

| | |Identify properties the design solution must have a minimum or maximum level of. |

| |Constraints: |> |

| | |Identify risks posed to human health and/or the environment by exposure to hazards. |

| |Environmental Risks: |> |

| | |Identify the criteria on which potential design solutions will be ranked. |

| |Ranking Criteria: |(1)> , (2)> , (3)> , (4)> . |

| | |Think up ideas for design solutions (“concepts”), even silly ones. Consider many viewpoints. |

|2. Conceptual |Brainstorm Concepts: |(a)> |

| | |Revisit Needs Analysis (and other phases) based on new information about Requirements, etc. |

| |Revisit Needs |> |

| | |Identify the combination of components (configuration) needed for the design. |

|3. Preliminary |Select Components: |> |

|Design: | | |

| | |Estimate component sizes. |

| |Simplified Sizing: |> |

| | |Estimate forces and examine responses to verify suitability. Specify potential materials. |

| |Simplified Analysis: |> |

| | |Reduce impacts on the environment resulting from human activities in the design. |

| |Environmental Impact: |> |

| | |Revisit Needs Analysis (and other phases) based on new information about Requirements, etc. |

| |Revisit Needs |> |

| | |Specify materials and how components will be assembled. |

|4. Detailed |Materials & Assembly: |> |

|Design: | | |

| | |Specify (and optimize) precise sizing of components and their interfaces (within the Constraints). |

| |Detailed Sizing: |> |

| | |Simulate forces acting on detailed model of system and examine responses. Adjust sizing. |

| |Detailed Analyses: |> |

| | |State the design solution completely and concisely so that someone could implement it. |

| |Solution Statement: |> |

| | |Revisit Needs Analysis (and other phases) based on new information about Requirements, etc. |
