Modular Door Lock Release Interfaces for Safety Standard Variants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door locking devices for household appliances are not modular and cannot be easily adapted to multiple release functions, requiring manufacturers to produce and stock multiple models to meet varying safety standards across different countries, which is costly and inefficient.
Innovation Solution
A modular door locking device with multiple releasing modules that can be selectively configured to implement various release functions, including manual, electrical, and automatic controls, allowing it to be adapted to different household appliances and safety standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If door locking devices are designed with different structures for different release functions to meet varying safety standards, then compliance with safety standards is achieved, but device complexity and the number of product models increase
Solution Approach 1:
The patent implements a universal door locking device structure that can perform multiple release functions (manual release, electrical release, automatic release) through a single standardized platform. The standardized interface and modular releasing modules allow the same basic structure to comply with different safety standards without requiring separate product models for each function.
Solution Approach 2:
The door locking device is divided into a standardized base structure and separate modular releasing modules. Each module (manual release module, electrical release module, automatic release module) can be independently selected and combined with the standardized structure, allowing manufacturers to configure the device according to specific safety standard requirements without redesigning the entire system.
2Adaptability or versatility
If multiple door locking device models are produced to meet different safety standards, then market coverage is improved, but production and inventory costs increase
Solution Approach 1:
By creating a universal standardized door locking device structure that can accommodate multiple releasing modules, manufacturers can produce a single base model and then configure it for different markets by adding or removing specific modules. This dramatically reduces the number of unique product models that need to be manufactured and stocked, lowering both production complexity and inventory carrying costs.
Solution Approach 2:
The system allows dynamic configuration of releasing modules based on market requirements. Rather than manufacturing fixed models for each market, the standardized structure enables flexible assembly of different module combinations to match specific safety standard requirements, allowing manufacturers to adapt to different markets without maintaining separate production lines for each model.
3Adaptability or versatility
If household appliance manufacturers stock multiple door locking device models to meet different safety standards, then customer requirements are satisfied, but inventory complexity and costs increase
Solution Approach 1:
The standardized door locking device structure with interchangeable releasing modules allows household appliance manufacturers to maintain a simplified inventory. Instead of stocking multiple complete device models, they can stock the standardized base structure and select specific releasing modules based on the safety standards required for each appliance model, significantly reducing inventory complexity.
Solution Approach 2:
By segmenting the door locking device into a standardized base and separate releasing modules, the system enables manufacturers to inventory only the common standardized components and then assemble different configurations as needed. This modular approach transforms inventory management from handling multiple complete assemblies to managing standardized parts and modules.
