INSIGHT
"Interactive toothbrushing apps and devices have sparked greater interest in brushing among children, leading to longer and more consistent brushing sessions."
“Although Apps can be effective, some parents do not want to spend time setting up their smartphones in the bathroom and worrying about their kids may drop and damage their phones. ”
"Both parents and children are drawn to toothbrushes with interesting shapes, vibrant colors, and familiar cartoon characters that they feel emotionally connected to."
PROCESS
The project started in a fuzzy front end phase focused on a core behavioral challenge—helping kids brush their teeth consistently and effectively, which is a well-known but poorly solved problem space.
We began by conducting parent and child interviews, behavioral observations, and benchmarking existing solutions to understand why current products fail in real use. The main issues weren’t just physical design—they were low engagement, short brushing duration, and lack of feedback loops that sustain behavior.
From this research, we synthesized key behavioral drivers around play, reward, and interaction feedback. Rather than moving directly into ideation, we used these insights to define clear design principles that guided the direction of the concepts.
We then translated those principles into a structured concept development process, working through multiple directions and narrowing them using user feedback and feasibility constraints.
The outcome was a toothbrush system that combines oral care with interactive behavioral reinforcement, designed not just as a product, but as a tool to improve brushing habits through engagement and feedback.
DEVELOPMENT
QUALITATIVE RESEARCH
Interviews, observational research, collaborated with third party research organization and internal customer insights for research analysis.
COMPETITOR RESEARCH
Understanding competitors by testing products, interview with actual users and read customer reviews to define Pros and Cons.
IDEATION
Explored ideas through quick sketches and review directions with internal stakeholders.
CONCEPT DESIGN
Refined sketches through 3 main concept directions based on Good-Better-Best strategy and differentiated the designs through its own innovative features.
LICENSE MANAGEMENT
Based on customers’ feedback, design was refined and partnered with both internal and external License Management team on character applications.
UX & UI
Collaborated with Marketing lead, License Manager and external software design team to build the interactive user interface and the sound effect as well as getting it approved through the Licensors.

FEELS LIKE PLAYING A VIDEO GAME
Interactive LED lighting and sound effects teach kids how to brush better and longer to reach their daily goals.
EMOTIONAL VALUE
Sonic the Hedgehog and his friends are one of kids’ all time favorites. Kids feel connected to them as new video games and movies were introduced.
PLATFORM DESIGN STRATEGY & EXTENDABILITY
The Firefly Kids Play Action™ toothbrush was developed as a flagship, premium-positioned product within the Firefly brand ecosystem. The core design was intentionally created as a durable, neutral platform rather than a single character execution.
This approach enables the base product architecture to support multiple SKU variations, including gender-specific editions and licensed character integrations, without requiring structural redesign.
Beyond visual customization, the system was designed to accommodate future expansion of sound UX, interactive play patterns, and digital engagement features, allowing the product to evolve with emerging technologies and shifting market expectations.
This establishes a scalable design foundation that can extend across future product generations while maintaining consistency in usability, manufacturing efficiency, and brand experience.
Product system designed by Simon, with subsequent SKU development by Rooz Mousavi.
