Research Topic 013 / 200
No rules for extending the product family
As new products move into different sizes and categories, the original design language becomes hard to carry forward.
Three-step solution method
- Distinguish fixed brand features from form features that change with function.
- Define rules for proportions, seams, interfaces and logo placement across future products.
- Test the rules on new products of different sizes and refine where they fall short.
Key Deliverables
- Product Family Extension Guidelines
- Feature Hierarchy Map
- Validation Prototypes
Verification Approach
Check that products remain recognisable across sizes while accommodating new functions.
Translating research into products and services
