Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock devices for movable objects, such as drawers and cabinets, often require manual unlocking mechanisms during power failures or electronic component damage, which can compromise convenience and aesthetic appeal.
Innovation Solution
A lock device comprising a slider, a driving module, a latch, and a power module, where the driving module moves the slider between locking and unlocking positions, and the latch is movable to block or allow movement of the second object based on the slider's position, with sensors and a resilient component for automatic operation and manual override.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual unlocking mechanism is added to the lock device, then reliability during power failure is improved, but device complexity and aesthetic appearance deteriorate
Solution Approach 1:
The patent merges the manual unlocking function with the existing slide rail assembly structure. The button is integrated into the slider, and the manual unlocking mechanism shares components with the normal locking mechanism, eliminating the need for separate manual release devices and maintaining aesthetic appearance while providing backup unlocking capability
Solution Approach 2:
The slider serves multiple functions: it acts as both the locking component during normal operation and the manual unlocking actuator during power failure. The button integrated into the slider allows the same structure to perform both automated locking and manual unlocking functions, reducing overall device complexity
2Reliability
If a manual unlocking mechanism is added to the lock device, then reliability during power failure is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The manual unlocking button is merged into the slider structure itself, making it an integral part of the visible component rather than an add-on. This integration ensures that the aesthetic appearance of the slide rail assembly is maintained while providing manual unlocking capability for power failure scenarios
3Ease of operation
If the latch is made movable to enable automatic unlocking, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The latch is designed to be movable rather than fixed, allowing it to automatically transition between locked and unlocked positions based on the slider's movement. This dynamic design enables automatic unlocking functionality while utilizing the existing mechanical components of the slide rail assembly, minimizing the increase in device complexity
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
The lock device provides secure locking and automatic unlocking functionality, ensuring convenience and aesthetic appeal by eliminating the need for additional manual unlocking mechanisms during power failures or component damage.
Implementation Method 1
the latch is driven by a movement of the second object to a predetermined position in an opening direction to move from an original state to a non-original state for driving the slider to move from the locking position to the unlocking position

AI summary
A lock device adapted for a first object and a second object movable relative to the first object includes a slider, a driving module, a latch and a power module. The driving module can drive the slider to move between a locking position and an unlocking position. The latch is movable relative to the slider. The power module can provide electricity to the driving module. When the second object is located at a retracted position relative to the first object, the driving module can drive the slider to move to the locking position, so that the latch blocks the second object. When the driving module is not driven by the power module, the latch is driven by the second object moving in an opening direction to move from an original state to a non-original state for driving the slider to move from the locking position to the unlocking position.
