Door Locking Assembly With Auto-Opening Unlock Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic casings do not provide visual indication of the unlocking status of the door, and the lock does not return to its original position after unlocking, causing inconvenience in use.
Innovation Solution
A door assembly with a locking mechanism comprising a first locking member, a second locking member, and a lock, where the first locking member is biased to move relative to the door base, and the second locking member is pushed away from the door base when unlocked, allowing the door to automatically open and the lock to return to its original position upon force release, utilizing inclined guiding surfaces and a resilient member for automatic operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door is unlocked manually without automatic movement, then the locking mechanism is simple, but the user cannot realize the unlocking status from the outer appearance and must manually push the door to check
Solution Approach 1:
The locking mechanism automatically performs the door opening action when unlocked, without requiring user intervention to manually push the door. The resilient member and pushing portion work together to automatically move the door to the open position, making the system self-serving in providing visual feedback of the unlock status.
Solution Approach 2:
The patent uses positional changes of the door and locking members as visual indicators of the lock status. When locked, the door is in the closed position with the first engaging portion engaged with the second engaging portion. When unlocked, the door automatically moves to the open position, providing clear visual feedback to the user about the unlock status.
2Ease of operation
If the lock does not return to original position after unlocking, then the structure is simpler, but the user must rotate the key frequently to convert between locked and unlocked states
Solution Approach 1:
The resilient member automatically returns the lock to its original position after unlocking, without requiring the user to manually rotate the key again. The resilient member stores energy during the unlocking process and automatically restores the locking member to its initial position, making the system self-resetting.
Solution Approach 2:
The locking mechanism operates in a periodic cycle: the user rotates the key to unlock, the door automatically opens, then the resilient member automatically returns the lock to the locked position. This periodic automatic return eliminates the need for continuous manual key rotation to maintain the locked state.
3Reliability
If the first body is biased to move in the first direction to engage the second engaging portion, then the door can be locked, but the user cannot visually determine the unlock status without manually pushing the door
Solution Approach 1:
The system automatically provides visual feedback about its own state. When the lock is engaged, the door is automatically positioned to show the locked state. When the lock is disengaged, the door automatically moves to show the unlocked state. This self-indicating behavior eliminates the need for users to manually push the door to check the lock status.
Solution Approach 2:
The locking mechanism provides immediate visual feedback to the user about the lock status through the door's position. The resilient member ensures that the door is always in the correct position to indicate whether the lock is engaged or disengaged, giving the user continuous feedback without requiring manual intervention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the door to automatically open when unlocked and the lock to return to its original position without user intervention, providing convenience and visual indication of the unlocking status, thus enhancing user experience.
Implementation Method 1
a first locking member disposed movably on the door base and biased to move relative to the door base in a first direction
Implementation Method 2
a resilient member allowing the door to automatically open when unlocked and the lock to return to its original position when the unlocking force is released

AI summary
A door assembly includes a door base, a door disposed pivotally on the door base for covering openably the door base, and a locking mechanism. The locking mechanism includes a first body biased to move relative to the door base in a first direction, a first engaging portion disposed at the first body, a pushing portion disposed at the first body, a second body disposed at the door, and a second engaging portion disposed at the second body. A lock is operable to move the first body relative to the door base in a second direction opposite to the first direction. The first engaging portion is biased to move in the first direction to thereby engage the second engaging portion, so as to lock the door at a locked position for covering the door base.
