Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door lock systems lack efficient electronic control mechanisms for securely managing access to storage areas, often relying on mechanical systems that are cumbersome and less secure.
Innovation Solution
A door lock system incorporating an electro-mechanical locking mechanism with a blocker bolt, actuator, retainer, and electronic controller, allowing for secure locking and unlocking via user input and credential verification, enabling controlled access through a portal like a door.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical locking system is used, then the door can be locked securely, but the system becomes cumbersome and less secure
Solution Approach 1:
The patent replaces traditional mechanical locking systems with an electro-mechanical system that uses an electronic controller, actuator, and electronic keypad for authentication. The controller receives electronic input from users and automatically actuates the blocker bolt, eliminating the need for complex manual mechanical operations while maintaining secure locking functionality.
2Ease of operation
If an electronic control mechanism is added to the lock system, then security and usability are enhanced, but the device complexity increases
Solution Approach 1:
The electronic controller serves multiple functions: it receives and processes electronic keypad input, validates credentials, controls the actuator to position the blocker bolt, and manages the retainer mechanism. This multi-functionality consolidates what could be separate complex systems into a single integrated control unit, enhancing ease of operation without proportionally increasing overall device complexity.
Solution Approach 2:
The retainer acts as an intermediary mechanism between the actuator and the blocker bolt. It provides a mechanical interface that translates the actuator's motion into secure positioning of the blocker, while also offering an additional layer of control. This intermediary simplifies the direct connection requirements between electronic control and mechanical locking components.
3Reliability
If a retainer mechanism is added to maintain the blocker position, then locking reliability is improved, but the device complexity increases
Solution Approach 1:
The retainer mechanism is designed to automatically engage and disengage based on the position of the blocker bolt. When the actuator moves the blocker to the locked or unlocked position, the retainer automatically secures that position without requiring additional manual intervention or complex control logic. This preliminary action ensures position stability while minimizing the complexity of control systems needed.

AI summary
The present disclosure generally relates to a lock including a blocker (e.g., a bolt) useable to selectively prevent access through a portal such as a door. The blocker can be retained in a blocking position to prevent access through the portal by a retainer. In alternative embodiments, the blocker can also be retained in an open position to allow access through the portal. A retainer can be utilized to retain the blocker in the blocking position preventing access through the portal and can also be utilized, in certain embodiments, to retain the blocker in the open position to allow access through the portal. A retainer blocker can be utilized to maintain the retainer in position to retain the blocker (e.g., bolt) in a fixed position. An actuator may, in certain alternative embodiments, be employed to position the retainer blocker. In certain embodiments, the actuator is controlled by an electronic controller.
