Dual Locking Latch with Manual and Electric Shuttle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking mechanisms for latches do not provide a secure and convenient dual locking system that can be unlocked electrically without manual assistance and optionally remotely, failing to prevent unauthorized access effectively.
Innovation Solution
A dual locking system incorporating a manual locking mechanism and an electrically actuated locking mechanism, with a shuttle that can be moved between engaged and disengaged positions by either manual or electrical actuation, ensuring secure locking and unlocking without manual intervention, and allowing remote operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a traditional manual locking mechanism is used, then the latch can be locked and unlocked manually, but it cannot be unlocked electrically without manual assistance
Solution Approach 1:
The patent combines a manual locking mechanism and an electrically actuated locking mechanism into a single integrated system. The manual locking means includes a manual lock plug that can be rotated to engage or disengage a shuttle, while the electrically actuated locking means includes a solenoid that can also move the shuttle. This merging allows the same shuttle to be controlled by either manual or electrical actuation, enabling electrical unlocking capability while maintaining manual operation option.
Solution Approach 2:
The shuttle component serves multiple functions: it acts as a locking element when engaged by the manual lock plug, and as a movable element actuated by the solenoid. The handle assembly also serves dual purposes as both a manual operating lever and an electrical actuation interface. This multi-functionality reduces the need for separate components for manual and electrical operation.
2Reliability
If a simple locking mechanism is used, then the device complexity is low, but it cannot provide secure dual locking and remote operation capability
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: a manual locking means with a manual lock plug, an electrically actuated locking means with a solenoid, and a shared shuttle component. This segmentation allows each component to perform its specific function while working together to provide enhanced security. The manual and electrical locking means can operate independently or in conjunction, providing redundant security measures.
Solution Approach 2:
The shuttle acts as an intermediary element between the manual lock plug and the solenoid. It receives actuation from either source and translates it into the appropriate mechanical action to lock or unlock the latch. This intermediary component enables the integration of manual and electrical control systems without requiring direct mechanical coupling between all components.
3Ease of operation
If manual operation is required for unlocking, then the ease of operation is maintained, but remote unlocking capability is lost
Solution Approach 1:
The locking mechanism is designed to be dynamic rather than static, allowing it to adapt between manual and electrical operation modes. The handle can be manually rotated to actuate the lock plug, or electrical signals can be applied to the solenoid to achieve the same result. This dynamic design enables the system to respond to different user needs and operating conditions.
Solution Approach 2:
The patent replaces the purely mechanical manual operation system with a hybrid system that incorporates electrical actuation. The solenoid provides an electrical-to-mechanical conversion capability, allowing remote actuation of the locking mechanism without requiring physical contact with the handle or lock plug. This substitution maintains ease of operation while adding remote capability.

AI summary
A dual locking system having a manual lock and an electrical lock, and a shuttle connected to both the manual lock and the electrical lock. The shuttle is moveable by either the manual lock or electrical lock between an engaged position in which a hook on the shuttle can engage a prong and a disengaged position in which the hook does not engage a prong. Upon de-energization of the electrical lock, the shuttle remains in the engaged position if the shuttle was in the engaged position prior to de-energization and the shuttle remains in the unengaged position if the shuttle were in the unengaged position prior to de-energization. The dual locking system is incorporated in a latch.
