Design Interview
What is the main principle, idea and inspiration behind your design?
The principle behind Aquaclean Oral Care is simplification. Oral hygiene today often requires multiple products — toothbrushes, water flossers, toothpaste, and mouthwash — each producing waste and requiring separate use. The inspiration came from imagining an all-in-one solution where water alone, enhanced by smart technology, could deliver comprehensive care. The hydrogen peroxide generator at the heart of Aquaclean transforms ordinary water into a safe antibacterial solution, challenging the conventional reliance on chemical-based or disposable products.
What has been your main focus in designing this work? Especially what did you want to achieve?
Our main focus was to merge effectiveness, convenience, and sustainability in a single compact device. We wanted to achieve professional-grade cleaning while reducing plastic waste and unnecessary chemical processing. The goal was not only to create an oral care device that performs well but also to make oral hygiene easier, more intuitive, and more environmentally responsible for everyday users.
What are your future plans for this award winning design?
Future plans include further refinement of the hydrogen peroxide generator for speed and efficiency, and potentially developing different models tailored to various user groups — such as children, seniors, and frequent travelers. We are also exploring integration with mobile health apps for personalized oral care routines. In the long term, we envision Aquaclean becoming part of a larger family of sustainable personal care products.
Grand Interview
Your innovative integration of a hydrogen peroxide generator in Aquaclean Oral Care represents a significant advancement in oral hygiene technology - could you elaborate on how this breakthrough technology transforms ordinary water into an effective antibacterial solution?
This innovation was made possible thanks to our incredible technology partners, who developed a patented system capable of generating low-density hydrogen peroxide directly from ordinary water. While the core chemical process is their proprietary advancement, our role was to push its application further through design and user integration.Traditionally, hydrogen peroxide-based oral care has required pre-made products like toothpaste or mouthwash. But with this embedded generator, we’re exploring a future where such pre-packaged solutions may no longer be necessary. Users can simply rely on water as a raw input—one that’s easily accessible and safe—and let the device generate the antibacterial agent on demand. This not only enhances convenience and sustainability, but also brings professional-grade oral care closer to daily home use or even outdoor scenarios.Ultimately, we see this as a step toward redefining oral hygiene—minimizing dependency on consumables, and making clean, effective care more accessible wherever you are.
The titanium nozzle design of Aquaclean Oral Care features three distinct cleaning modes - what inspired your team to develop these specific stream patterns, and how do they enhance the overall oral care experience?
The development of the titanium nozzle and its three cleaning modes was the result of an iterative design process—full of debates, testing, and user scenario evaluations. Traditionally, water flossers were primarily designed to clean between teeth. But we wanted to go beyond that—to reimagine water-based oral care as a complete solution for full-mouth hygiene.So we stepped back and asked: how does effective cleaning actually happen in the mouth? Brushing works because it physically contacts plaque and debris. So we knew our water streams had to replicate that same level of contact and force—but using only water.That led us to develop three distinct stream modes:1. A narrow, high-pressure stream for precise cleaning between teeth.2. A wide-angle spray to sweep across larger surfaces like the gumline or cheeks.3. A 360-degree mist or rotating spray for general rinsing and refreshing.By allowing users to switch between these modes, the device provides a tailored and more complete oral care experience—replacing not just the floss, but potentially the brush and even toothpaste. With the hydrogen peroxide-enhanced water as the cleaning medium, users can achieve a high level of hygiene with minimal consumables. The nozzle’s titanium construction also ensures durability, safety, and excellent bacterial resistance.In short, the nozzle isn’t just a delivery mechanism—it’s a multifunctional tool that redefines how we clean our mouths.
Considering the environmental impact of traditional oral care products, how does Aquaclean Oral Care's all-in-one approach contribute to reducing plastic waste while maintaining professional-grade cleaning effectiveness?
Absolutely—sustainability was a core principle from the very beginning of AquaClean’s design. We asked ourselves a simple but powerful question: What if one tool could take care of the entire oral hygiene routine?In today’s typical oral care regimen, you need multiple products: a toothbrush, toothpaste, mouthwash, floss, and often a water flosser. Most of these come in separate plastic containers, involve complex chemical production, and are meant to be replaced frequently—creating significant plastic waste and resource consumption.With AquaClean, we aimed to consolidate all of that into a single, reusable device. Thanks to the breakthrough technology from our partners—specifically the integrated hydrogen peroxide generator—we were able to transform regular water into a safe, antibacterial cleaning medium. That meant no need for toothpaste or mouthwash. By adjusting water pressure and flow direction through our titanium nozzle, users can clean every part of the mouth: teeth, gums, tongue, and cheeks, with just water.Environmentally, this is a major step forward. Not only does it drastically reduce plastic packaging waste, but the hydrogen peroxide generated (H₂O₂) breaks down naturally into water and oxygen—leaving no harmful residue behind.At first, even we wondered if it was too good to be true. But through design, testing, and collaboration, we realized it was entirely achievable: a product that delivers professional-grade oral care while dramatically reducing environmental impact.
