The Design

About Gentle X Elektrisk Tandbørste

Gentle X er en elektrisk tandbørste designet til daglig mundhygiejne. Børsten fastgøres magnetisk til en vægmonteret dock, der også fungerer som trådløs opladningsstation, så enheden holdes væk fra badeværelsets overflader, og krydskontaminering reduceres. Der tilbydes tre børstetilstande: Clean, Sensitive og Whitening. Bløde kulstofbørstehår giver en skånsom rengøring, og et rejsehætte med UV-C-lys desinficerer børstehårene under opbevaring. Den slanke krop er IPX7-klassificeret for vandmodstand, og en sonisk motor når op på 40.000 vibrationer i minuttet.

Production Technology
GentleX has IPX 7 water-resistance keeping it protected against splashes and moisture.
Design Challenge
The biggest challenge in designing GentleX was integrating wireless charging into a slim, ergonomic form while ensuring 100 days battery life and IPX7 waterproofing. Embedding a compact coil system, optimizing power efficiency, and achieving seamless sealing required multiple PCB iterations and precision engineering. Advanced CAD modeling, material selection, and prototyping helped create a minimalist, high-performance design.
Research
The design of GentleX is rooted in extensive research on oral hygiene and user preferences. Ergonomic studies guided the toothbrush’s shape and size for maximum user comfort. Collaborations with dental professionals ensured compliance with oral health standards. Research on UV-C light verified its efficacy in bacterial elimination, and tests on bristle materials optimized gentleness and cleaning efficiency, resulting in a toothbrush that meets both practical and aesthetic needs.
Inspiration
GentleX is inspired by the elephant (strong, intelligent, and gentle), symbolizing both power and care in oral hygiene. Traditional toothbrushes and many existing electric models often lack ergonomics, hygiene solutions, and convenience-driven features. We envisioned GentleX as a seamless blend of technology, hygiene, and aesthetics, transforming the daily routine of brushing into an effortless and premium experience.
Project Duration
Duration: 4 to 5 months (Started- Sept 12 2024, completed- Jan 5 2025), Location: Mumbai (India)
Operation Flow
The toothbrush magnetically attaches to the wall mount, which serves as a wireless charging dock. Users can switch between three brushing modes- Clean, Sensitive, and Whitening to suit individual needs. The UV-C Travel Cap actively disinfects the bristles, ensuring bacteria-free storage. The soft charcoal bristles provide a deep yet gentle clean, ensuring optimal oral health.
