Product Design Prompt: Children's Bookshelf
Design a primarily physical bookshelf for children to use at home, with optional lightweight digital support such as an assembly guide. The goal is to make books accessible, safe, engaging, and practical for caregivers.
Constraints & Assumptions
Prioritize children roughly ages 3-8, while considering younger siblings and caregivers.
Assume home use first; classroom use can be a future extension.
Safety, ergonomics, affordability, durability, and ease of assembly are core constraints.
Avoid unnecessary electronics or app dependency in the MVP unless strongly justified.
Clarifying Questions to Ask Guidance
What age range, price point, and room size should the design target?
Is this for direct-to-consumer retail, schools, libraries, or a furniture brand?
Are there regulatory or certification requirements we must meet?
Should the product optimize for reading frequency, independence, organization, or caregiver convenience?
Part 1 - Target Users and Pain Points
Define primary, secondary, and relevant tertiary users, then list key pain points for each.
What This Part Should Cover Guidance
Children, caregivers, and possible educators or childcare providers.
Reachability, visibility, safety, clutter, cleanup, durability, and assembly pain points.
Differences between child motivation and caregiver needs.
Part 2 - Design Principles
Outline guiding principles across safety, ergonomics, engagement, and practical home use.
What This Part Should Cover Guidance
Anti-tip design, rounded edges, non-toxic materials, and safe anchoring.
Child-height access, front-facing display, simple organization, and easy cleanup.
Engagement mechanisms that encourage reading without adding risky complexity.
Part 3 - MVP Features
Propose a minimum viable product feature set and explain what you would intentionally exclude from v1.
What This Part Should Cover Guidance
A concrete physical design with dimensions, shelves, bins, labels, materials, and assembly guidance.
Explicit v1 exclusions such as electronics, wheels, apps, or complex modularity if they increase risk.
Possible v2 extensions after safety and usability are validated.
Part 4 - Metrics and Validation
Define success metrics and how you would measure them after launch.
