Evaluating Existing Products for Design Improvement

i. Context of the Product & Future Design Decisions

Understanding the background of the product helps predict future needs.

Aspect	Examples	Why it Matters
Original Environment	Indoor/outdoor, climate, cultural setting	Ensures new designs suit current usage
User Demographics	Age, ability, lifestyle	Adapts product for wider or updated user groups
Technological Context	Available tech when product was designed	Allows incorporation of new tech advancements

ii. Materials & Components

Materials affect everything from cost to environmental impact.

Material Type	Impact on Product	Design Opportunity
Plastics	Lightweight, versatile but may lack durability	Use recyclable plastics or bio-based alternatives
Metals	Strong, durable but heavier and costlier	Lightweight alloys for better portability
Textiles	Comfort, aesthetics, flexible use	Smart textiles with tech integration

iii. Methods of Construction & Manufacture

The way a product is made influences cost, quality, and customisation.

• Mass Production: Efficient, lowers costs but less flexible
• Handmade: Higher quality, unique but expensive
• Modular Assembly: Easy repair & upgrades

iv. How Functionality is Achieved

Good design solves problems effectively:

• Mechanisms should be reliable and user-friendly
• Consider electronic features that enhance usability
• Think about maintenance and repair ease

v. Ease of Use: Ergonomics & Anthropometrics

Design must fit human users comfortably.

Consideration	Details	Example
Control Layout	Positioning for ease & accessibility	Buttons reachable without stretching
Grip Size	Fits wide range of hand sizes	Adjustable handles
Anthropometric Data	Human body measurements for design limits	Seat height accommodating 5th–95th percentile

vi. Inclusivity & User Variety

• Accessibility features (e.g., tactile buttons, voice commands)
• Adjustable settings for different ages and abilities
• Design for diverse cultural contexts

vii. Fitness for Purpose

Ensure the product does what it’s supposed to do, reliably.

• Durable under normal and extreme use
• Meets relevant safety and quality standards
• User feedback shows product meets expectations

viii. Impact on User Lifestyles

Products can transform daily routines positively or negatively.

• Does it save time or effort?
• Is it easy to maintain or clean?
• Does it promote health or convenience?

ix. Trends, Taste & Style

Looks matter as much as function.

• Is the design modern and attractive?
• Does it fit target market preferences?
• Does it balance aesthetics with usability?

x. Marketing & Branding

Marketing shapes how customers see the product.

• Strong branding builds trust and loyalty
• Packaging influences buying decisions
• Social media presence raises awareness

xi. How to Get a Product to Market

Distribution and logistics impact success.

Factor	Considerations	Impact
Distribution Channels	Online, retail, wholesale	Reach & convenience for customers
Logistics	Shipping methods, storage	Cost & delivery speed
Regulations	Legal requirements, certifications	Market access & product safety
