Welcome to "Factors Influencing the Development of Products"!
Hi there! In this chapter, we’re going to explore what actually makes a product "good." Designing isn’t just about making something look "cool"—it’s about understanding people, how their bodies work, and how designers throughout history have changed the way we think about the world. Don't worry if some of the history names or long words like "anthropometrics" seem a bit scary at first; we’ll break them down into bite-sized pieces together!
By the end of these notes, you’ll understand why your favorite gadget feels right in your hand and why a chair from 100 years ago looks so different from one today.
1. User-Centred Design (UCD)
User-Centred Design is a fancy way of saying "putting the person who uses the product first." Instead of a designer saying "I want to make a purple triangle toaster," they ask, "How does the user want to toast their bread?"
When designers use UCD, they focus on five key areas:
a) User Needs, Wants, and Values:
- Needs: Things the product must do (e.g., a car must be safe).
- Wants: Things that make the product more desirable (e.g., a car having a heated steering wheel).
- Values: What the user cares about, like sustainability or ethical making.
b) Purpose: What is the product actually for? A hammer’s purpose is to hit nails, so it needs to be heavy and strong.
c) Functionality: Does it actually work? If a "smart" kettle takes 20 minutes to boil because the app is glitchy, it has poor functionality.
d) Innovation: This is about coming up with new, clever ways to solve a problem. Think about how the first "bagless" vacuum cleaner changed everything.
e) Authenticity: This means the product is "real" and honest. It doesn't pretend to be something it’s not (like plastic made to look like expensive wood).
Quick Review: The "Ice Cream" Analogy
- Need: Something cold and sweet.
- Want: Sprinkles and a flake.
- Functionality: The cone shouldn't leak!
- Innovation: An edible spoon made of biscuit.
Key Takeaway: If you don't design for the user, the user won't buy your product!
2. Anthropometrics and Ergonomics
These two words are often confused, but they are like a "measurement" and its "application."
Anthropometrics (The Data)
Anthropometrics is the study of human body measurements. Designers use charts (data) that tell them how long the average arm is, how wide a hand is, or how tall a person is.
Did you know? Designers usually design for the 5th to 95th percentile. This means they try to make products fit 90% of the population, leaving out the very smallest 5% and the very tallest 5% to keep costs down.
Ergonomics (The Comfort)
Ergonomics is about how we interact with a product. It’s the application of anthropometric data to make sure a product is comfortable, easy to use, and safe.
Example: A computer mouse.
- Anthropometrics tells the designer how big the average hand is.
- Ergonomics is the curved shape that stops your wrist from aching after an hour of gaming.
Memory Aid: The Two "A"s and "E"s
Anthropometrics = All the sizes (numbers).
Ergonomics = Ease of use (comfort).
Common Mistake to Avoid: Don't just say a product is "ergonomic" because it's comfortable. Explain why—e.g., "The handle is textured for grip and shaped to fit the palm, making it ergonomic."
Key Takeaway: Anthropometrics provides the numbers; Ergonomics uses those numbers to create comfort.
3. Aesthetics: Form vs. Function
Aesthetics is all about how a product looks. There is a famous debate in design about which is more important: Form (looks) or Function (how it works).
a) Form over Function: The product is designed to look beautiful or artistic first, even if it’s a bit difficult to use.
Example: A high-fashion shoe that looks amazing but is painful to walk in.
b) Form follows Function: The product’s look is decided entirely by what it needs to do.
Example: A laboratory microscope or a hammer. It doesn't need to be "pretty," it just needs to work perfectly.
Key Takeaway: Most successful commercial products find a balance between both!
4. Key Historical Movements and Figures
Designers don't work in a vacuum; they get inspired by the past! You need to know these key movements for your exam.
Arts and Crafts (William Morris):
- Style: Natural patterns (flowers/birds), high-quality wood, "hand-made" feel.
- Big Idea: Hated the "soulless" machines of the Industrial Revolution. Wanted to go back to traditional crafts.
Art Nouveau (Charles Rennie Mackintosh):
- Style: "Whiplash" curves, flowing lines, and stylized flowers.
- Big Idea: Wanted to make art a part of everyday life, from buildings to jewelry.
Bauhaus Modernist (Marianne Brandt):
- Style: Very simple, geometric shapes (circles/squares), used industrial materials like chrome and steel.
- Big Idea: "Form follows function." They embraced machines to make good design affordable for everyone.
Art Deco (Eileen Gray):
- Style: Bold geometric shapes, sunburst patterns, and expensive-looking materials like lacquer and chrome.
- Big Idea: Represented luxury, glamor, and the "roaring 20s."
Streamlining (Raymond Loewy):
- Style: Teardrop shapes, smooth curves, "speed lines."
- Big Idea: Making things look fast and modern, even if they didn't move (like a fridge or a toaster!).
Post Modernism (Philippe Starck):
- Style: Fun, quirky, and sometimes weird! Often uses bright colors and strange shapes.
- Big Idea: "Less is a bore." They challenged the "boring" rules of Modernism. Think of the Juicy Salif lemon squeezer—it looks like an alien, but it’s actually for juice!
Memphis (Ettore Sottsass):
- Style: Bright neon colors, crazy patterns (like leopard print or zig-zags), and weird geometric mashups.
- Big Idea: Designing products to be playful and shocking rather than just functional.
Quick Review: Match the Designer!
- William Morris: Nature and hand-made.
- Marianne Brandt: Simple and industrial.
- Philippe Starck: Quirky and Post-Modern.
- Raymond Loewy: Fast and curvy (Streamlining).
Key Takeaway: History is a pendulum—it swings from very decorated (Arts and Crafts) to very simple (Bauhaus) and back again (Post-Modernism)!
Final Summary for Chapter 5
To design a successful product, you must:
1. Put the User at the center of your thinking.
2. Use Anthropometric data to make the product Ergonomic.
3. Decide if the Form or the Function is the priority.
4. Learn from Historical Movements to understand style and materials.
Keep practicing by looking at objects around your house—ask yourself: Is this ergonomic? Who was the target user? Does it look like it was inspired by the Bauhaus or Art Deco? You've got this!
