Rotatable Lock Housing Attachment for Easier Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking systems, such as those in safes and doors, often do not allow for easy access or replacement of components like keypads and other internal components, making maintenance and servicing difficult.
Innovation Solution
An attachment system comprising a baseplate with circumferential cutouts and lugs, and a housing with protrusions that engage with the cutouts to prevent withdrawal, along with a locking device accessible from outside for rotatable locking and unlocking, allowing the housing to be securely fastened and easily serviced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the housing is permanently fixed to the baseplate, then the system stability is improved, but the ease of repair deteriorates
Solution Approach 1:
The attachment system divides the locking system into separable components: a baseplate mounted to the closure, and a housing containing serviceable components. The housing can be detached from the baseplate through rotational movement, allowing segmentation of the system for maintenance while maintaining stability during normal operation.
Solution Approach 2:
The attachment system transitions from a static permanent fixation to a dynamic reversible connection. The housing can be rotated to engage or disengage from the baseplate, providing dynamic adjustability that allows the system to switch between stable operation mode and maintenance mode.

3Reliability
If the locking device is enclosed inside the housing, then the security is improved, but the ease of repair deteriorates
Solution Approach 1:
The locking system is segmented into a secure baseplate housing and a separate serviceable housing unit. The locking device remains secured to the baseplate while the outer housing can be removed, allowing the locking mechanism to maintain security while becoming accessible for maintenance through the detachable housing design.
Solution Approach 2:
The serviceable housing containing components like the keypad is extracted as a separate detachable unit from the baseplate. This allows the locking device to remain securely mounted while the outer housing and its components can be removed for servicing without affecting the security of the core locking mechanism.
4Ease of repair
If the housing is rotatably engaged with the baseplate, then the ease of repair is improved, but the device complexity increases
Solution Approach 1:
The attachment system divides the locking system into separable components: a baseplate mounted to the closure, and a housing containing serviceable components. The housing can be detached from the baseplate through rotational movement, allowing segmentation of the system for maintenance while maintaining stability during normal operation.

AI summary
An attachment system for a locking system mounted to a closure is provided. A baseplate is fastenable to a mounting surface of the closure, the baseplate including at least one circumferential cutout having an engagement feature, and a locking feature on a surface of the baseplate. A housing has at least one protrusion insertable into the at least one circumferential cutout and is rotatably engageable with the engagement feature to selectively prevent the housing from being withdrawn from the baseplate in a direction normal to the mounting surface. A locking device is disposed inside the housing and is accessible from outside the housing through a cutout defined in at least one of the housing and the baseplate, the locking device operable to rotatably lock and unlock the housing to the baseplate.
