Solution Overview

Problem

Existing security locks for safes and gun cabinets require additional installation space and adjustments when combining electric motor-driven and key-operated locking mechanisms, limiting simplified assembly and handling.

Innovation Solution

A security lock design featuring movement-coupled locking levers that interact with both the key-operated and electric motor-driven mechanisms, allowing equivalent operation and emergency access without the need for a second lock housing or additional adjustments, using a standard lock housing and keyhole position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If two separate lock housings are used to accommodate both electric motor-driven and key-operated locking mechanisms, then both locking mechanisms can be provided, but the installation space requirement increases and additional modifications are needed

Engineering Contradiction:
Improvelocking mechanism functionalityVSAvoidinstallation space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines two separate locking mechanisms (electric motor-driven and key-operated) into a single integrated lock housing. The lock bolt is shared between both mechanisms, and the components are arranged to fit within one standardized housing, eliminating the need for two separate installations and reducing the overall space required.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lock housing is designed as a universal standardized housing that accommodates multiple locking mechanisms simultaneously. The same lock bolt serves both the electric motor-driven mechanism and the key-operated mechanism, allowing the single housing to perform multiple locking functions without requiring separate specialized housings for each mechanism type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If two separate lock housings are used to accommodate both electric motor-driven and key-operated locking mechanisms, then both locking mechanisms can be provided, but assembly complexity and handling difficulty increase

Engineering Contradiction:
Improvelocking mechanism functionalityVSAvoidassembly and handling
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent merges the installation of two separate locking mechanisms into a single assembly unit. By integrating both mechanisms within one standardized lock housing and using a shared lock bolt, the number of assembly steps is reduced, and handling is simplified compared to installing two separate housings independently.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated lock housing is designed with modular internal components that can be assembled in a standardized sequence. The electric motor-driven mechanism and key-operated mechanism are segmented into distinct but compatible sub-assemblies within the housing, allowing for systematic assembly and easier manufacturing processes.

Inventive Principle:
Principle #1Segmentation

3Reliability

If a key-operated locking mechanism is placed downstream of an electrically operated locking mechanism in the operational sequence, then emergency operation is possible, but additional modifications are required for installation

Engineering Contradiction:
Improveemergency operation capabilityVSAvoidinstallation requirements
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent combines the emergency key-operated mechanism and the primary electric motor-driven mechanism into a single integrated housing with a shared lock bolt. This merging allows emergency operation capability to be achieved without requiring separate downstream installation, as both mechanisms operate on the same locking element within the unified housing structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The standardized lock housing is designed as a universal platform that inherently supports both normal electric operation and emergency key operation simultaneously. The housing and lock bolt configuration is universal enough to accommodate both operational modes without requiring additional modifications or specialized installation arrangements.

Inventive Principle:
Principle #6Universality (Multi-functionality)
