Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door handles with locks pose safety and convenience issues for multiple users, as they require physical keys and often add bulky hardware when converted to electronic keyless solutions, which can compromise the traditional form factor.
Innovation Solution
An electronic keyless door lock integrated into the door handle, featuring a user-graspable handle with an interface that detects credentials and gestures, allowing secure unlocking without additional hardware, and enabling network connectivity for enhanced access and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional door handles are converted to electronic keyless solutions, then keyless access and enhanced security are achieved, but the door handle becomes bulky and loses its traditional form factor
Solution Approach 1:
The patent combines the electronic lock mechanism, interface, and control components directly into the door handle assembly, merging multiple functions into a single integrated unit. This eliminates the need for separate electronic lock hardware mounted on the door, thereby maintaining a compact form factor while providing keyless access functionality.
Solution Approach 2:
The door handle is designed to perform multiple functions: it serves as both a traditional manual door opening mechanism and an electronic keyless access system. The interface can accept various credential types (biometric, card, code), and the handle itself can be operated manually or electronically, making it a multi-functional device that replaces several separate components.
2Adaptability or versatility
If electronic keyless solutions are added to door handles, then access control capabilities are enhanced, but the device complexity increases
Solution Approach 1:
The patent introduces a controller as an intermediary component that manages the interaction between the interface (credential input) and the lock mechanism. The controller processes credential verification and controls the lock actuation, thereby simplifying the overall system architecture by centralizing control logic and reducing direct complexity between input and output components.
Solution Approach 2:
The door handle system performs automatic credential verification and lock actuation without requiring manual intervention beyond presenting the credential. The interface automatically detects and verifies credentials, and the controller automatically actuates the lock when verification succeeds, reducing operational complexity for the user.
3Ease of operation
If traditional door handles with physical keys are used, then simple and reliable operation is maintained, but safety and convenience issues arise for multiple users
Solution Approach 1:
The door handle system dynamically adapts its access control method based on the presented credential. It can switch between different authentication modes (biometric, card, code, or manual key operation) and automatically adjusts the locking mechanism's response based on verification results, providing both simplicity for individual users and versatility for multiple users.

AI summary
An electric door lock uses an interface to receive a credential to disengage a door lock. The interface is disposed on the user-graspable handle. The interface may comprise a sensor that receives a credential, such as an alphanumeric or symbolic code, a biometric input, or any appropriate combination of inputs. After a credential is entered, a gesture may be input to the interface to indicate that the credential is complete and prompt a controller to disengage the lock device. A gesture may comprise a motion or series or motions. The electric door lock also provides a control system that can be networked to allow remote entry of a credential. The control system can also control a plurality of door handles through a single door, or provide controls through remote devices.
