Modular Lock Body with Interchangeable Modules for Adjustable Backset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lock manufacturing process requires a multitude of different article codes for various backset distances, leading to increased production, storage, and management costs due to the need for multiple variations of locks, resulting in unused capital tied up in resources.
Innovation Solution
A modular and standardized lock design featuring a box-like body with removable modules, spacing means, and transmission elements that allow for adjustable backset distances by interposing plates of predefined thickness, enabling the same components to be used across different configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If locks are made with dedicated designs for specific backset distances, then the lock fits specific door configurations, but the number of article codes and inventory requirements increase
Solution Approach 1:
The lock is divided into a standardized body and interchangeable modules (spring latch module, sliding latch module) that can be independently configured. This segmentation allows the same body to serve multiple backset requirements by simply changing modules, reducing the need for completely different lock designs for each backset distance.
Solution Approach 2:
The lock system incorporates adjustable elements including interchangeable modules with different positioning characteristics and spacing means that can be configured to achieve different backset distances. This dynamic configurability allows a single standardized lock body to adapt to various door configurations without requiring multiple dedicated designs.
2Adaptability or versatility
If multiple variations of locks are produced for different backset distances, then market demands are met, but production, storage, and management costs increase
Solution Approach 1:
The standardized lock body is designed to be universal and compatible with multiple modules and configurations. This multi-functionality allows the same body to serve different backset requirements, enabling the company to meet diverse market demands while producing fewer unique lock variations, thereby improving production and management efficiency.
Solution Approach 2:
Instead of creating different lock designs for each backset distance, the system changes specific parameters (module types, spacing configurations) of a standardized body. This parameter-based customization allows efficient production of varied lock configurations from a single base design, reducing the complexity of production and inventory management.
3Reliability
If inventory stock is maintained for each article code, then unforeseen market variability is covered, but capital is tied up in unused resources
Solution Approach 1:
By segmenting the lock into standardized body and interchangeable modules, the company can maintain inventory of common components rather than complete finished locks for every possible configuration. This modular inventory approach reduces capital tie-up while maintaining the ability to respond to market variability by assembling different configurations from available modules.
Solution Approach 2:
The modular design enables easy replacement and reconfiguration of modules. When market demands shift, the company can discard less demanded configurations and recover/reuse the standardized bodies and modules for more demanded configurations, reducing the need to maintain large inventories of all possible variations.
