Solution Overview

Problem

Existing modular housing systems for devices attached to mounting rails lack versatility, ease of assembly, and operational reliability, particularly in industrial control technology, where devices need to be stacked and connected efficiently with varying voltage and current requirements.

Innovation Solution

A modular housing system with a first housing part that accommodates multiple coupling modules for power and signal lines, featuring a deflectable locking mechanism and blocking element for secure connection, allowing for easy adaptation to different voltage and current levels, and eliminating the need for manual wiring through the use of coupling modules that can be secured without tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If devices are connected using traditional connecting cables and terminals, then electrical connections can be established, but assembly is time-consuming and requires manual wiring

Engineering Contradiction:
Improveassembly speedVSAvoidease of assembly
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The housing is divided into multiple detachable parts (first housing part, second housing part) that can be assembled separately and then connected. This segmentation allows for pre-assembly of components and simplifies the overall assembly process by breaking down complex wiring tasks into modular steps.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Coupling modules are integrated within the housing structure, with signal line coupling modules and power line coupling modules nested within respective housing parts. This nesting eliminates the need for external connecting cables and terminals, as connections are made internally through the coupled modules.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If coupling modules are integrated into the housing, then modularity and adaptability are improved, but device complexity increases

Engineering Contradiction:
Improveadaptability to different voltage and current levelsVSAvoidhousing structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The housing system is designed with universal coupling modules that can handle different types of connections (signal lines and power lines) and different voltage/current levels. The first and second housing parts can be combined in various configurations, and coupling modules can be selectively installed based on specific application requirements, providing multi-functionality without requiring entirely different housing designs for each application.

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

Solution Approach 2:

The housing parts are designed to be detachably connectable, allowing the system to be dynamically configured. Users can assemble or disassemble housing parts and coupling modules based on specific needs, enabling the system to adapt its complexity level to match the actual application requirements rather than always maintaining maximum complexity.

Inventive Principle:
Principle #15Dynamics

3Reliability

If a locking mechanism is used to secure housing parts, then connection reliability is improved, but the assembly process becomes more complex

Engineering Contradiction:
Improveconnection reliabilityVSAvoidlocking mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking mechanism is designed to automatically engage when the first housing part and second housing part are connected. The locking elements self-activate through the connection process itself, eliminating the need for separate manual locking operations. This self-service approach maintains high connection reliability while avoiding the complexity of manually operated locking systems.

Inventive Principle:
Principle #25Self-service

4Productivity

If manual wiring is required for power and signal lines, then flexibility in connection configuration is maintained, but assembly time and potential for errors increase

Engineering Contradiction:
Improveassembly timeVSAvoidoperational reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

Coupling modules for signal lines and power lines are nested within the housing structure, with connection terminals and contact elements pre-positioned within the modules. This nesting eliminates the need for manual wiring operations, as all electrical connections are pre-established within the coupling modules during manufacturing, thereby reducing assembly time while ensuring reliable connections.

Inventive Principle:
Principle #7Nested doll (Nesting)
