Solution Overview

Problem

Existing lock devices for slide rail assemblies require manual unlocking mechanisms during power failures or electronic component damage, compromising convenience and aesthetic appeal.

Innovation Solution

A lock device with a slider, driving module, latch, and power module that automatically transitions between locking and unlocking positions using a magnetic component and resilient force, allowing manual unlocking without additional mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a manual release mechanism is added to allow manual unlocking during power failure or electronic component damage, then the reliability is improved, but the device complexity increases and aesthetic appearance deteriorates

Engineering Contradiction:
Improvemanual unlocking capabilityVSAvoidadditional mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes the manual release mechanism from the visible exterior and integrates it into the interior structure of the lock device. The release button is positioned inside the lock body, accessible only when the latch is in the unlocked state, thereby eliminating the need for external manual release components that would compromise aesthetic appearance while maintaining manual unlocking capability for reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent combines the manual release function with the existing electronic locking mechanism by integrating the release button and spring-loaded latch system into the same housing. This merging eliminates the need for separate manual release mechanisms that would add to device complexity, as the manual release shares structural elements with the electronic locking system.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a manual release mechanism is added to allow manual unlocking during power failure or electronic component damage, then the reliability is improved, but the aesthetic appearance deteriorates

Engineering Contradiction:
Improvemanual unlocking capabilityVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The patent removes the manual release mechanism from the visible exterior and integrates it into the interior structure of the lock device. The release button is positioned inside the lock body, accessible only when the latch is in the unlocked state, thereby eliminating the need for external manual release components that would compromise aesthetic appearance while maintaining manual unlocking capability for reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If additional manual unlocking mechanisms are disposed on the outer surface of the cabinet, then the ease of operation is improved, but the aesthetic appearance deteriorates

Engineering Contradiction:

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

Ensures secure locking and easy manual unlocking without additional mechanisms, enhancing convenience and aesthetic appeal by eliminating the need for manual releases.

Implementation Method 1

The driving module includes a magnetic component configured to retain the slider at the unlocking position when the slider is located at the unlocking position

Methodology Applied
Scientific EffectMagnetic force: Magnetism

Implementation Method 2

a movement of the second object from the predetermined position in a retracted direction is able to cause the latch to move from the non-original state to the original state in response to a resilient force provided by the resilient component

Methodology Applied
Scientific EffectElastic force: Elasticity

AI summary

A lock device(20) adapted for a first object(24) and a second object(26) movable relative to the first object(24) includes a slider(58), a driving module(60), a latch(62) and a power module(90). The driving module(60) can drive the slider(58) to move between a locking position(Xl) and an unlocking position(X2). The latch(62) is movable relative to the slider(58). The power module(90) can provide electricity to the driving module(60). When the second object(26) is located at a retracted position(R) relative to the first object(24), the driving module(60) can drive the slider(58) to move to the locking position(Xl), so that the latch(62) blocks the second object(26). When the driving module(60) is not driven by the power module(90), the latch(62) is driven by the second object(26) moving in an opening direction(Dl) to move from an original state(S1) to a non-original state(S2) for driving the slider(58) to move from the locking position(Xl) to the unlocking position(X2).
