Smart Multipoint Lock Control for Low-Effort Secure Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locks, particularly multipoint locks, require substantial effort to operate and lack efficient integration with smart home technology, often requiring manual operation and lacking seamless connectivity with remote devices.
Innovation Solution
An access controller is used to control a lock mechanism, transitioning between modes such as authorized access, entry, and unlocked states, allowing handles to be decoupled or coupled with the lock mechanism based on user proximity and device inputs, enabling efficient operation and remote control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multipoint locks with multiple latches or bolts are used to enhance security, then security and sealing performance are improved, but the effort required to operate the lock increases significantly
Solution Approach 1:
The lock mechanism is divided into multiple independent latches or bolts that can be controlled separately. The access controller manages each latch independently, allowing selective engagement and disengagement. This segmentation enables the system to maintain high security through multiple locking points while reducing operational effort by controlling each segment independently rather than requiring simultaneous manipulation of all latches.
Solution Approach 2:
The lock system transitions from a static mechanical operation to a dynamic electronically controlled system. The access controller dynamically adjusts the state of each latch based on real-time conditions, user authentication, and operational mode. This dynamic control allows the system to optimize security posture while simplifying user interaction through automated decision-making about which latches to engage or disengage.
2Ease of operation
If traditional cylindrical or mortise locks are used, then ease of operation is maintained, but security and sealing performance are insufficient
Solution Approach 1:
The access controller serves multiple functions: it controls traditional latch mechanisms, integrates with smart home systems, provides remote access capabilities, and manages multiple latches simultaneously. This multi-functionality allows the system to maintain the operational simplicity of traditional locks while adding enhanced security features and smart home integration, effectively bridging the gap between simple operation and advanced security.
Solution Approach 2:
The access controller acts as an intermediary between the user and the lock mechanism. Instead of directly manipulating complex mechanical latches, users interact with simplified interfaces (keypads, smartphones, remotes) that communicate with the access controller, which then translates commands into appropriate latch operations. This intermediary layer abstracts the complexity from the user while maintaining secure and reliable locking functionality.
3Ease of operation
If powered systems with keypads or smart phones are used to control deadbolts remotely, then ease of operation and convenience are improved, but device complexity and packaging requirements increase
Solution Approach 1:
The access controller merges multiple control functions into a single integrated unit: remote access via keypad and smartphone, local manual operation, and direct latch control all occur within one compact device. This consolidation eliminates the need for separate powered systems, keypads, and control mechanisms, thereby reducing overall packaging size while maintaining comprehensive remote access capability and ease of operation.
Solution Approach 2:
The access controller is designed to be self-contained with integrated power, control logic, and communication capabilities. The system manages its own operations without requiring external powered systems or complex packaging. The controller autonomously handles authentication, latch control, and status monitoring, reducing the need for additional components and minimizing packaging requirements while providing convenient remote access functionality.

AI summary
A method of controlling a lock mechanism of an active door includes transiting an access controller of the lock mechanism to an authorized access mode and transitioning the access controller from the authorized access mode to an entry mode. Transitioning the access controller to the authorized access mode is in response to an authorized user being sensed approaching the active door from an exterior side of the active door or in response to input on a remote device. In the authorized access mode, an exterior handle of the active door is decoupled from a main latch of the lock mechanism. Transitioning the access controller to the entry mode is in response to sensed contact with the exterior handle. In the entry mode, the exterior handle is capable of rotating to transition the access controller to an unlocked mode in which the exterior handle is operably coupled to the main latch.
