Study Notes
Design Process
- Systematic approach to creating products that solve problems and meet user needs.
- Steps include problem identification, context research, concept generation, prototype development, and testing.
- Final production and evaluation confirm that the product achieves intended goals and user requirements.
Strength and Durability of Materials
- Strength of materials: ability to withstand force; durability: endurance of wear over time.
- Key properties:
- Tensile strength: resistance to being stretched.
- Hardness: resistance to surface deformation.
- Impact resistance: capability to absorb shock.
- Testing methods include tensile testing and hardness testing to measure properties.
Life Cycle Analysis (LCA)
- Evaluates environmental impacts of a product from raw material extraction to disposal.
- Steps include defining goals, conducting inventory analysis, assessing impacts, and interpreting data for decision-making.
Types of Market Research
- Involves both primary research (surveys, interviews) for new data and secondary research (existing reports) for pre-collected information.
- Qualitative research focuses on user attitudes, while quantitative research identifies trends through numerical data.
- Both approaches are crucial for understanding market needs and product improvement.
Collaborative Design Teams
- Teams consist of diverse professionals: designers, engineers, marketers, and manufacturers.
- Collaboration enhances creativity, improves efficiency, and bolsters problem-solving through shared expertise.
Industrial Design and Production Processes
- Focuses on creating aesthetically pleasing and functional products.
- Production techniques include:
- Casting: pouring material into molds.
- Molding: shaping materials using molds.
- Machining: cutting materials to specifications.
- Quality control ensures products meet performance and safety standards.
Ergonomic Design
- Aims to develop products that align with human body movements for better comfort and usability.
- Key principles include user comfort, ease of use, and risk minimization.
- User testing and prototyping refine ergonomic features based on actual feedback.
Evaluation Methods
- Assess product effectiveness and performance using formative and summative evaluations.
- User testing collects feedback; benchmarking compares products against similar ones.
- Criteria for evaluation include usability, performance, and aesthetics.
Renewable Materials in Product Design
- Renewable materials replenish naturally, promoting sustainability and reducing environmental impact.
- Examples: bamboo (biodegradable, fast-growing) and recycled plastics (resource conservation).
- Utilizing renewable materials lowers carbon footprint in product design.
Gantt Charts
- Visual project management tool displaying task timelines.
- Tasks are shown on the vertical axis; time on the horizontal, with bars representing durations.
- Effective for project planning and tracking progress.
Production Techniques
- Injection molding: enables high-volume manufacturing using molds.
- CNC machining: provides precise cutting controlled by computer.
- 3D printing: additive manufacturing that builds products layer by layer.
- Each technique chosen based on product requirements and production scale.
3D Modeling and Simulation Software
- Allows designers to create detailed digital representations of products.
- CAD software (e.g., SolidWorks) helps visualize designs; simulation tools (e.g., ANSYS) test product performance under different conditions.
- Aids in design optimization.
Range of Communication Strategies
- Effective strategies include:
- Visual: diagrams and prototypes for clarity.
- Written: reports and specifications for documentation.
- Oral: presentations and discussions for stakeholder engagement.
- Essential for conveying ideas, sharing feedback, and keeping stakeholders informed.
Artificial Intelligence (AI)
- AI involves machine systems that mimic human intelligence.
- In design, AI facilitates automation of design processes and predictive analytics.
