Solution Overview

Problem

Existing modular connectors face challenges in adaptability, assembly complexity, and handling difficulties due to their multi-part design, which limits flexibility and increases the number of required parts and assembly steps.

Innovation Solution

A modular connector system with terminal blocks and contact carrier modules is developed, utilizing projections and recesses for a positive and/or non-positive connection, allowing pre-assembly of a module strip as a structural unit, simplifying handling and assembly by forming a temporary connection through clamping elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If modular connectors use a multi-part design with separate terminal blocks and contact carrier modules, then adaptability to different contacting tasks is improved, but assembly complexity increases

Engineering Contradiction:
Improveadaptability to different contacting tasksVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connector is divided into separate terminal blocks and contact carrier modules that can be independently manufactured and then assembled together, allowing different configurations for different contacting tasks while maintaining manageable assembly through standardized connection interfaces

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The terminal blocks are designed with universal connection features (projections and recesses) that can accommodate different contact carrier modules, allowing the same terminal block design to serve multiple functions across various connector configurations

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

2Adaptability or versatility

If modular connectors use a multi-part design with multiple individual parts, then flexibility in configuration is improved, but the number of required parts increases

Engineering Contradiction:
Improveflexibility in configurationVSAvoidnumber of required parts
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

Multiple contact carrier modules are combined with terminal blocks to form integrated module blocks, reducing the total number of separate parts by merging functions into unified assemblies that can be handled and installed as single units

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If modular connectors use a multi-part design, then adaptability to different contacting requirements is improved, but handling difficulty increases

Engineering Contradiction:
Improveadaptability to different contacting requirementsVSAvoidhandling difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Contact carrier modules are merged with terminal blocks to form integrated module blocks that can be handled as single units, improving ease of operation by reducing the number of separate components that need to be manipulated during assembly and installation

Inventive Principle:
Principle #5Merging (Combining)

4Productivity

If modular connectors use pre-assembly of terminal blocks and contact carrier modules, then assembly speed is improved, but the number of assembly steps increases

Engineering Contradiction:
Improveassembly speedVSAvoidnumber of assembly steps
Core Design Contradiction:
