Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety locking systems require high design effort for different configurations and incur significant costs due to the need for multiple module variants and complete system replacement upon module defects.
Innovation Solution
A modular arrangement with rotationally symmetrical connection modules allowing for flexible attachment of handle modules on either side, reducing the need for multiple variants and enabling modular interchangeability, with a data bus system for independent internal communication and simplified cabling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple variants of the locking module are provided to cover different configurations (right-hand or left-hand attachment), then adaptability to different configurations is improved, but device complexity and design effort increase
Solution Approach 1:
The patent applies asymmetry by providing only one variant of the locking module with a standardized connection module, while the handle module is designed to be attachable on either side (right or left). This reverses the conventional approach where the locking module would be customized for each configuration. The asymmetric design of the handle module accommodates different mounting situations without requiring multiple locking module variants, thus reducing design effort while maintaining adaptability.
2Reliability
If the entire safety locking system is sent back for repairs when a module develops a defect, then reliability is maintained, but loss of time and repair costs increase
Solution Approach 1:
The patent applies segmentation by designing the safety locking system as modular components (locking module, handle module, function modules) that can be independently replaced. The connection modules use standardized plug-and-socket interfaces that enable easy detachment and replacement of individual modules. When a defect occurs, only the affected module needs to be replaced rather than returning the entire system, significantly reducing repair time and costs while maintaining system reliability through proper module substitution.
3Ease of repair
If standardized connection modules are used to enable modular interchangeability, then ease of repair is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies universality by designing the connection module with standardized mechanical and electrical interfaces that can be used across all locking modules regardless of configuration. The connection module serves multiple functions: mechanical coupling, electrical connection, and alignment guidance. This standardized interface enables easy modular replacement while the manufacturing precision is concentrated in the standardized connection module itself, which can be produced with high precision using standard manufacturing processes, rather than requiring precision in multiple variant-specific designs.

AI summary
The invention relates to a module arrangement (1) comprising at least one base module, which has a connection module on each of two different sides, and at least one functional module with at least one connection module. The connection modules of the base module are designed to be rotationally invariant with respect to their mechanical and electrical connections, so that by rotating the base module either its first or second connection module can be selectively contacted on the connection module of the functional module.
