Certainly, technologies are already available that allow you to lighten your load in this way; however, many of them are prone to being compromised. Kwon Hyuk-Sang's goal was to design a [passcode access method](https://www.trendhunter.com/trends/tcl-dr2-max-retrofit-smart-lock) that could not be learned by observation. The priority was to hide the buttons so that no passer-by would be able to see the PIN that is input into the [modern combination locking system](https://www.trendhunter.com/trends/smart-lock-technology). Keeping the door itself looking sleek and simple, the mechanism is actually embedded into the back of the [elongated knob](https://www.trendhunter.com/trends/aqara-smart-lock-u300). The homeowner can grasp the Pattern Door Lock and press the four buttons with each of his fingers, initiating entry without revealing a thing. ## Trend Insights (Trend Hunter) - Score: 4.6/10 - Popularity: 78% | Activity: 51% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Gen Z, Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) ## Key Themes ### What's Driving This Trend - **Concealed Door Locks:** Developing door locks that can be accessed and opened without the use of keys or combination buttons would be a game-changer in the conventional door lock industry. - **Non-observable Access Methods:** Designing access methods that cannot be observed through technology (such as cameras) is the next step in securing homes and businesses. - **Embedded Technology:** Many everyday products could benefit from embedded technology development, making them sleek and simple while still being high-tech. ### Who This Affects Most - **Home Security:** The door lock industry could tap into this technological advancement to create more secure and advanced locking systems for home and business security. - **Smart Home Technology:** Developments in smart home technology could see the introduction of modern, inconspicuous door locks controlled through digital means such as smartphones or voice assistants. - **Interior Design:** Innovation in the field of door locks could lead to a new trend of sleek, embedded technology in home furnishings and interior design. ## Related on Trend Hunter - [Interior Push-Pull Door Locks](https://www.trendhunter.com/trends/anylock-milda.md) - [Quad-Access Connected Doorknobs](https://www.trendhunter.com/trends/tcl-k1.md) - [Palm-Recognizing Smart Locks](https://www.trendhunter.com/trends/smart-deadbolt.md) - [Intuitive Access Smart Locks](https://www.trendhunter.com/trends/ultraloq-latch-5.md) - [Palm Recognition Smart Deadbolts](https://www.trendhunter.com/trends/wifi-palm-recognition-smart-deadbolt.md) - [Multifunctional Smart Door Locks](https://www.trendhunter.com/trends/lockin-veno-pro.md) - [High-Tech Residential Security Systems](https://www.trendhunter.com/trends/residential-security-system.md) - [Camera-Equipped Door Systems](https://www.trendhunter.com/trends/plus-link-z-concept.md) - [Biometric Scanner Smart Locks](https://www.trendhunter.com/trends/lockly-flex-touch.md)
