Solution Overview

Problem

Existing electrical installation systems require time-consuming and costly assembly of module-specific cables for each system module, leading to increased space requirements and non-uniform module bases, which hinder efficient and cost-effective installation.

Innovation Solution

A modular design featuring a square base extension with a grid dimension of 17.75 mm, allowing for uniform module bases and integrated bus connection technology, enabling frameless flush mounting and pre-assembled bus lines with insulation displacement contacts, reducing on-site assembly complexity and space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If module-specific cables are assembled on site for each system module, then connection flexibility is achieved, but assembly time and costs increase significantly

Engineering Contradiction:
Improveconnection flexibilityVSAvoidassembly time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements pre-assembled bus lines with integrated insulation displacement contacts that are manufactured off-site and delivered ready-for-installation. The bus lines come with pre-attached contacts in standardized configurations, eliminating the need for on-site cable assembly and connection work, thus dramatically reducing installation time while maintaining connection flexibility through modular design

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates universal connection components that can be used across different system modules. The standardized bus lines with insulation displacement contacts serve multiple modules simultaneously, and the uniform grid-based mounting system allows the same connection technology to be applied throughout the entire installation, reducing the variety of specialized cables needed

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

2Adaptability or versatility

If module-specific cables are assembled for each system module, then individual module connections are achieved, but space requirements for cable accommodation increase

Engineering Contradiction:
Improvemodule connection capabilityVSAvoidspace for connection lines
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent merges multiple cable functions into a single integrated bus line system. Instead of having separate cables for different connections, the bus lines combine power supply, signal transmission, and communication functions in unified conductors with integrated contacts, significantly reducing the total volume required for cable accommodation

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The standardized bus lines serve multiple purposes across different modules - providing both power and data connections, supporting various module types, and enabling different connection topologies. This universal approach eliminates the need for multiple specialized cable types, reducing overall space requirements

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

3Adaptability or versatility

If non-uniform module bases are used to adapt to different functional upper parts, then module-specific functionality is achieved, but manufacturing complexity and assembly difficulty increase

Engineering Contradiction:
Improvemodule functionalityVSAvoidmodule base variety
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the system into standardized modular components: uniform module bases with standardized mounting interfaces, detachable functional upper parts, and standardized bus lines. This segmentation allows different functional upper parts to be mounted on identical bases, reducing manufacturing complexity while maintaining functional diversity through the variety of upper parts

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements universal module bases that can accommodate multiple types of functional upper parts through standardized interfaces and mounting mechanisms. The same base design serves different functions by supporting various upper parts, eliminating the need for custom-designed bases for each module type and significantly reducing manufacturing complexity

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

AI summary

The module has a functional upper part (3) releasably connected with a module base part (2), which is fastened at a system support part. The module base part comprises a cuboid base part (4) in which a circuitry carrier (6) with an electronic circuit is received. The circuitry carrier comprises contacts (7, 8) i.e. series contacts, for a terminal of a bus line. The contacts are electrically connected with each other to form input pads and output pads of an electrical signal processing unit and a power supply. The contacts are accessible through apertures (11) in the cuboid base part.
