Rotary Locker Lock Prevents Bolt Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locker locks are susceptible to unauthorized access due to the potential for the locking bolt to be pushed or jammed out of engagement, especially in single-point locking systems, which lack secure retention in the extended position, and additional bolts in multiple-point systems increase complexity and cost.
Innovation Solution
A rotary locking member that rotates between locking and releasing positions, secured by a sliding locking bolt, which is configured to remain in a locked position until properly manipulated, preventing unauthorized retraction and enhancing security by creating a dead-locked condition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional retractable locking bolt is used in a single-point locker lock, then the locking mechanism is simple and cost-effective, but the locking bolt may be pushed or jammed out of engagement without proper operation, compromising security
Solution Approach 1:
The locking member transitions from a static sliding bolt to a dynamic rotary mechanism that moves between locked and unlocked positions through rotation. This rotational movement provides more controlled engagement and disengagement, preventing unauthorized manipulation while maintaining single-point simplicity
Solution Approach 2:
The locking member is pre-positioned in a secured locked state where it cannot be easily manipulated. The rotary design ensures the locking member is already engaged and secured before any unlocking attempt, requiring proper operation of the lock interface to initiate the unlocking sequence
2Reliability
If multiple locking bolts are used to improve security, then security against unauthorized entry is enhanced, but the device complexity and cost increase
Solution Approach 1:
The invention changes the operational parameter of the locking member from linear sliding movement to rotational movement. This parameter change allows a single locking member to provide enhanced security through controlled rotational engagement and disengagement, eliminating the need for multiple bolts while maintaining or improving security

AI summary
A lock includes a lock housing, a lock interface, a rotary locking member, a locking bolt, and a locking mechanism. The rotary locking member extends from a side portion of the lock housing, the rotary locking member being rotatable about a first axis between a locking position and a releasing position. The locking bolt is configured to hold the rotary locking element in the locking position when the locking bolt is in a first position and to allow the rotary locking member to rotate from the locking position to the releasing position when the locking bolt is in a second position. The locking mechanism is configured to slide the locking bolt from the first position to the second position in response to proper manipulation of the lock interface.
