DESSMANN Q5 Fingerprint Smart Lock
Making Home Security Simpler and More Convenient
Innovation Insights
Project Background
The DESSMANN Q5 was developed as the brand’s first premium fully automatic fingerprint smart lock.
The project aimed to accelerate the development of an Internet of Things lifestyle and create an influential smart home security product for users worldwide.
Innovation Value
The Q5 was introduced as the world’s first fully automatic fingerprint lock with an integrated handle design.
Its automatic unlocking system simplifies the entire door-opening process. After fingerprint identification, users do not need to rotate a handle, push a lever, or perform any additional action.
The door can be opened directly with a simple push, creating a more convenient and worry-free smart living experience.
Design Strategy
Product Strategy
The product design draws futuristic inspiration from concept sports cars.
Unnecessary decorative elements were removed in favor of a minimalist and integrated design language.
The streamlined appearance gives the lock a modern, premium identity while establishing a new design direction for the smart lock industry.
Functional Upgrade
The Q5 provides fully automatic locking after the door is closed.
Once the lock body detects that the door has shut, the main locking bolt automatically extends without requiring users to lock the door manually.
This feature allows users to leave home with greater confidence without repeatedly turning back to check whether the door is locked.
User Experience
The lock uses biometric fingerprint recognition for instant touch-based unlocking.
Its fingerprint sensor completes identification in less than 0.5 seconds.
Supported by a German-developed algorithm, the system can predict, combine, and continuously learn fingerprint information, improving recognition speed and accuracy through repeated use.
It can also reliably identify the fingerprints of elderly users and children.
Exterior Design Upgrade
The overall appearance emphasizes a refined metallic texture, creating a secure, premium, and fashionable entrance for modern homes.
The touch-sensitive control panel responds with the speed and sensitivity of a smartphone screen, providing users with immediate and intuitive operating feedback.
💡 Solution
1. Durable Structure and Enhanced Physical Security
The main lock housing is manufactured from aluminum alloy.
It incorporates a patented three-level security structure designed to resist prying, impact, and unauthorized entry, while complying with national lock-body standards.
The internal transmission components are precision-cast from stainless steel, providing strong rust resistance, durability, and reliable long-term performance.
2. Smart Privacy Protection and Connected Security
The lock features an intelligent anti-peeping password system that allows users to enter additional random digits before or after the correct password.
This prevents nearby individuals from easily identifying the actual access code.
The Q5 can also connect to the Xiaodi App, enabling users to receive notifications when family members arrive home, generate temporary passwords for one-time access within a specified period, and receive alerts when forced entry or tampering is detected.
These connected security features make home access management safer, simpler, and more convenient.
