Vault Door Inner Handle Drive Train Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vault door systems lack a secure and user-friendly mechanism for locking and unlocking, particularly from both inside and outside, which can lead to unauthorized access or operational difficulties.
Innovation Solution
A vault door system with a drive system comprising a prime mover and drive train that moves locking bolts between locked and unlocked positions, featuring an inner handle for interior access and an outer handle that automatically extends for exterior use, ensuring secure locking and easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional locking mechanism is used, then the door can be locked from the interior, but it cannot be securely locked from the exterior and allows unauthorized access
Solution Approach 1:
The locking mechanism is divided into separate functional components: an inner handle system for interior locking and an outer handle system for exterior locking. Each handle operates independently through its own drive train, allowing secure locking from both sides while maintaining clear operational separation between interior and exterior access methods.
Solution Approach 2:
The drive system is designed to accommodate multiple locking functions through a single integrated structure. The prime mover can actuate different drive trains depending on which handle is operated, providing both interior and exterior locking capabilities within one unified mechanism, thereby improving security without requiring separate independent locking systems.
2Ease of operation
If the outer handle is always extended for easy gripping, then exterior access is convenient, but it allows unauthorized users to easily grab and open the door
Solution Approach 1:
The outer handle is designed to be dynamically positioned rather than fixed. It automatically extends when the door is opened from the interior, providing convenient gripping for legitimate users. However, the handle retracts when the door is closed, removing the gripping advantage from unauthorized users attempting to force entry. This dynamic behavior adapts the handle's accessibility based on the door's operational state.
Solution Approach 2:
The outer handle automatically extends and retracts based on the door's position without requiring manual intervention. The drive system autonomously positions the handle to extend when needed for opening and retract when the door is closed, providing self-regulating accessibility that prevents unauthorized use while maintaining convenience for authorized users.
3Ease of operation
If the inner handle is always engaged with the drive train for automatic locking, then locking is convenient, but it prevents manual override for emergency access
Solution Approach 1:
The inner handle's engagement with the drive train is dynamic rather than fixed. During normal operation, the handle remains engaged with the drive train for automatic locking convenience. However, the system includes a release mechanism that can disengage the inner handle from the drive train when emergency access is needed, allowing manual override while maintaining normal convenient operation during regular use.
Solution Approach 2:
The drive train acts as an intermediary between the inner handle and the locking bolts. During normal operation, the drive train transmits power from the inner handle to automatically move the locking bolts. When emergency access is required, a release mechanism interrupts this intermediary connection, allowing manual manipulation of the locking bolts independent of the handle, thus providing emergency override capability while maintaining automatic locking convenience.
4Reliability
If multiple locking bolts are used for secure locking, then security is improved, but the complexity of the locking mechanism increases
Solution Approach 1:
Multiple locking bolts are merged into a single unified locking mechanism controlled by the drive system. Both the inner and outer handle drive trains converge on the same locking bolts, allowing multiple bolts to be actuated simultaneously through a coordinated system rather than requiring separate independent mechanisms for each bolt, thereby reducing overall structural complexity.
Solution Approach 2:
The drive system is designed to universally control all locking bolts through a single prime mover and coordinated drive trains. Both interior and exterior handles can actuate the same set of locking bolts, providing multi-functional control over the locking mechanism. This universal approach allows secure locking with multiple bolts while avoiding the complexity of separate specialized mechanisms for different locking functions.

AI summary
A vault door system for use in a vault includes a door supporting a plurality of locking bolts that move between locked and unlocked positions. A drive system includes a prime mover and a drive train. The prime mover actuates the drive train to move the locking bolts between the locked and unlocked positions. An inner handle is at an inner side of the door and is arranged to be accessible from an interior of the vault. The inner handle is operatively coupled to the drive train and is movable between a first position and a second position. In the first position, the drive train operatively couples the prime mover to the plurality of locking bolts so that the prime mover can move the locking bolts between the locked and unlocked positions. In the second position, the drive train does not operatively couple the prime mover to the plurality of locking bolts.
