Study Notes
Engineering Design Process
- A series of steps engineers follow to create solutions to problems.
- The process is iterative, involving multiple redesigns.
- It's a decision-making process that involves science, math, and engineering.
- The goal is to convert resources into solutions based on identified opportunities, analysis, synthesis, and evaluations of various solutions.
- Designing a system, component, or process, meets specifications and constraints.
Defining the Problem
- Understanding the problem, who needs a solution, and why it's important.
- Determining why the issue needs to be addressed.
- Identifying users or customers, existing solutions, and necessary requirements.
Requirements
- Defining the characteristics that the solution must possess for success.
- Determining important characteristics the solution must meet.
- Listing design requirements.
- Brainstorming and evaluating various potential solutions.
Building a Prototype
- Creating a functional model of the solution.
- Building an operating version of a solution.
Testing and Redesign
- Testing the design and finding weaknesses.
- Conducting iterative testing and redesign, making improvements based on findings.
- Iterations and refinements to the design through repeated testing.
Communicating Results
- Effectively communicating final results through reports and presentations.
- Reporting and showcasing project results to others.
Constraints
- Conditions that must be met; for example, external factors such as schedules or limitations of technology.
- Constraints can be in the form of codes, standards, or technical regulations.
Interoperability
- A product or system’s ability to work with other products and systems.
- Products or systems that work together without limitations.
Standards
- Providing a framework for technical requirements.
- Standards help avoid incompatibilities in programs or projects, reducing implementation timeframes.
Codes
- Laws that define minimum safety and health standards (e.g., building codes).
- Codes specify requirements for product development.
Technical Regulations
- Government-defined product characteristics and production methods.
- Specifications with mandatory compliance.
Organizations
- Defining standards, codes, and regulations (e.g., ASTM, IEEE, ASME).
- Organizations providing guidelines and definitions for standards, codes, and regulatory frameworks.
Design Goals
- Defining the characteristics of a computer system (e.g., features, weight, reliability, expandability, and power consumption).
Cost
- Keeping costs consistent with commercial or device criteria.
Performance
- Evaluating overall device functionality.
Power Consumption
- Optimizing power efficiency while achieving results.
Hardware
- Microprocessors or micro-controllers are used in embedded systems.
Research
- Including literature and studies related to the current research.
- Critically analyzing literature to identify shortcomings and justify the need for the research.
- Gathering information from various (primary and secondary) sources.
- Using different approaches to draw conclusions – including analytical reading and critical evaluation.
- Understanding and applying literature review approaches systematically.
Quantitative Approaches
- Descriptive research: understanding.
- Correlational/comparative research: understanding relationships.
- Experimental research: testing.
- Developmental research: understanding change.
Statistical Treatment
- Considerations for using statistical treatments for testing, like independent observations, homogeneity of variance, and normality (Bell curve) of data.
- Treatments for comparing groups or assessing relationships among variables are defined, along with the considerations in those tests.
Types of Tests
- Parametric tests(e.g., t-test, ANOVA, MANOVA): assumptions about data distribution (normally distributed).
- Non-parametric tests (e.g., Chi-square test, etc.): no assumptions about data distribution are required.
- Correlation tests (e.g., Pearson’s r): identify correlations between variables.
- Regression tests (e.g., simple and multiple linear regression): identify cause-and-effect relationships.
