Quatro Toothbrush

Next-gen four sided toothbrush system.

Toothbrushes rely on manual technique, prone to user error, inconsistent results, and long brushing times. QuatroBrush addresses these issues by automating multi surface cleaning, minimizing human variability, and elevating the hygiene experience.

Revolutionizing brushing for excellence in oral care.

What We Did

Utilizing field studies and consumer interviews, RKS investigated brushing habits and pain points, time constraints, inconsistent cleaning, and user fatigue. Our Psycho‑Aesthetics® approach revealed the emotional drivers of cleanliness, confidence, and aesthetics.

How We Used Psycho-Aesthetics™ to Identify Unique Opportunities in the Project.

Using our proprietary Psycho-Aesthetics® 2.0 framework, we conducted in-depth interviews and ethnographic observation in diverse lab settings. We identified key emotional and usability pain points — such as intimidation with complex interfaces, workspace clutter, and trust in precision. These insights guided both the form and interface strategy, ensuring approachability and confidence in operation.

The Quatro toothbrush was revamped to create a higher perceived value in the category, leveraging clinically proven technology previously developed under the 30 Second Smile brand. RKS updated the design, usability, and engineering to provide a world-class consumer design that customers would be proud of and ruggedization to ensure the product would last. The team created a design and brand that elevated experience to compete with emerging new consumer brands in the dental category. The added benefit of the quad-head bristles increased cleaning efficacy and reduced brushing time from 2 minutes to 30 seconds.

CMF Strategy

Refined Industrial Design Language

Our strategic approach focused on creating a brand identity system that not only communicates QuatroBrush’s mission but also ensures consistency across all touchpoints. The strategy involved developing a comprehensive set of brand guidelines, encompassing the logo, colors, typography, and visual elements. The decision to customize the Gilroy typeface and create a monochromatic color scheme aimed to establish a modern and cohesive brand image. Our strategy also emphasized the importance of whitespace, ensuring a clean and professional presentation of brand elements. We developed multiple versions of the logo, considering different applications such as social media, product branding, and favicon, to maintain versatility while adhering to a unified brand message.
