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.
