This [smartly designed doorknob](https://www.trendhunter.com/trends/ross-lovegroves-door-handles) by Arnaud Lapierre is one of those “why didn't I think of that” moments. You can't make the whole door disappear (or the kids) so why not the knob. **Implications** - Products like this take an age-old problem that most people would probably assume has long been addressed and find an altogether new and utterly innovative way to solve it. On top of being functionally ingenious, this kind of invention also has a rewarding novelty aspect that is bound to get people talking long after they see it. ## Trend Insights (Trend Hunter) - Score: 4.4/10 - Popularity: 79% | Activity: 44% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Unique](https://www.trendhunter.com/unique) > [Inventions](https://www.trendhunter.com/inventions) ## Key Themes ### Key Themes Behind This Trend - **Smart Doorknobs:** Disappearing doorknobs like Arnaud Lapierre's design are an example of the innovative potential of smart technology in everyday objects. - **Invisible Design:** The disappearing doorknob trend highlights the growing interest in minimalistic and invisible design solutions that seamlessly blend into their surroundings. - **Novelty User Experience:** By creating doorknobs that disappear, there is an opportunity for businesses to cater to customers who appreciate unique and novel experiences in their everyday interactions. ### Where This Applies - **Smart Home Technology:** The disappearing doorknob trend aligns with the broader adoption of smart home technology, offering potential opportunities for companies in this industry to innovate and create seamless and intuitive experiences. - **Interior Design:** The trend of invisible doorknobs presents an opportunity for interior designers to incorporate discreet and elegant solutions into their projects, enhancing the overall aesthetic appeal of spaces. - **Hospitality Industry:** Disappearing doorknobs can provide a unique and memorable guest experience, making them particularly relevant for hotels and accommodations seeking to differentiate themselves in the industry. ## Related on Trend Hunter - [Quad-Access Connected Doorknobs](https://www.trendhunter.com/trends/tcl-k1.md) - [Minimalist Sound-Free Doorbells](https://www.trendhunter.com/trends/silent-doorbell.md) - [Domed Door Knob Designs](https://www.trendhunter.com/trends/h03-knob-on-half-moon.md) - [Adaptable Key Lock Designs](https://www.trendhunter.com/trends/advanced-rekey.md) - [Hands-Free Home Doors](https://www.trendhunter.com/trends/milda-evolve-door.md) - [Innovative Customizable Door Systems](https://www.trendhunter.com/trends/customizable-door-system.md) - [Tooth-Shaped Active Doorbell Concepts](https://www.trendhunter.com/trends/skitter.md) - [Discreet Retrofit Smart Locks](https://www.trendhunter.com/trends/yale-linus-smart-lock-2-lite.md) - [Hands-Free Door Handle Devices](https://www.trendhunter.com/trends/safe-lever-door-opener.md)
