Solution Overview
Problem
Conventional key-operated locking systems face issues such as key duplication, loss, and tampering, while electronic locks struggle with energy efficiency, torque handling, and ease of installation, especially when retrofitting into existing locks.
Innovation Solution
A handle set for door locks featuring an authentication circuit and actuator within the interior handle, coupled with a coupling cartridge that handles increased torque and prevents unauthorized state changes, allowing for easy retrofitting and secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic access control means are located on the outside of the door, then ease of operation is improved, but security against tampering deteriorates
Solution Approach 1:
The patent inverts the conventional location of electronic access control means by placing them inside the door rather than outside. This reversal allows the system to maintain ease of operation through interior handles while simultaneously protecting against external tampering attempts, as the electronic components are now shielded from external access.
Solution Approach 2:
The patent introduces a coupling mechanism as an intermediary between the interior handle and the latch. This coupling can be in either a coupled state (transmitting force) or decoupled state (blocking force), allowing the system to maintain ease of operation when authorized while preventing unauthorized access even if the interior handle is accessed.
2Object-affected harmful factors
If through connection is used to connect electronics inside the door, then security against tampering is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent extracts the electronic access control means from the traditional through-door connection and relocates them to be contained within the interior handle assembly. This extraction eliminates the need for complex through-door wiring and connections, reducing device complexity and installation difficulty while maintaining security by keeping electronics inside the door.
3Ease of manufacture
If conventional key-operated systems are used, then ease of manufacture is improved, but security against key duplication and loss deteriorates
Solution Approach 1:
The patent replaces the mechanical key-operated system with an electronic access control system using transponders and authentication circuits. This substitution eliminates the security vulnerabilities of key duplication and loss while maintaining ease of manufacture through standardized electronic components and modular assembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances security by protecting against tampering and energy inefficiency, enabling secure, low-power operation with increased torque handling and easy installation, making it suitable for various door types and orientations.
Implementation Method 1
The electronic access control means comprises a wireless data signal receiver which receives signals transmitted from a remote transmitter operated by a user. Since the remote transmitter transmits data signals using an alternating magnetic field
Implementation Method 2
Once an authorized signal is recognized by the access control means, a solenoid is activated to control a coupling element which in turn allows the lock to be moved in a locked or unlocked position

AI summary
The present invention provides for a handle set for a lock with a latch, the handle set having an authentication circuit and actuator in the interior handle that allow access to authenticated transponders. The present invention also provides a device and method for transmitting a rotational movement and force in an electronic lock, wherein the transmission takes place in a coupled state and not in a decoupled state and wherein the transmission of force does not damage an actuator that requires little energy to change between the coupled and decoupled states. A coupling cartridge of an electronic lock can easily be handed. The electronic lock can be retrofitted in installed mortise locks and used with cylindrical locks. The electronic lock can include a security feature that prohibits the electronic lock from changing between the coupled and decoupled states.
