Solution Overview

Problem

Existing modular industrial connectors face limitations in modularity and flexibility due to a limited number of connector module slots, which also increases assembly effort.

Innovation Solution

The connector module is composed of at least two independent functional units that can operate independently and combine synergistically, featuring a cavity filled with a fixative for secure attachment, allowing for increased modularity without additional assembly complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of connector module slots in a mounting frame is increased to enhance modularity and flexibility, then the adaptability of the industrial connector is improved, but the device complexity and assembly effort increase

Engineering Contradiction:
Improvemodularity and flexibilityVSAvoidassembly effort
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functional units (contact carrier unit, terminal unit, housing unit) into a single integrated connector module that is pre-assembled as one component. This merging approach allows the module to be installed as a single unit in the mounting frame, thereby enhancing modularity and flexibility without increasing assembly effort, since the complex internal assembly is already completed during manufacturing.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If connector modules are made highly modular with multiple independent functional units to improve adaptability, then the versatility is enhanced, but the device complexity increases due to more components

Engineering Contradiction:
ImprovemodularityVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connector module is segmented into distinct functional units (contact carrier unit with contacts, terminal unit with terminals, housing unit with housing) that are independently designed and manufactured. These segmented units are then assembled into a complete module during manufacturing, allowing for high modularity and adaptability while keeping the complexity managed through standardized interfaces and pre-assembly processes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple independent functional units are merged into a single integrated connector module that functions as one cohesive component. This merging eliminates the need for end-users to assemble multiple separate components, thereby achieving high modularity without increasing the perceived device complexity for the user.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of repair

If functional units are designed to be independently replaceable to enhance ease of repair and reuse, then the ease of repair is improved, but the device complexity increases due to additional connection and fixation mechanisms

Engineering Contradiction:
ImprovereplaceabilityVSAvoidconnection mechanisms
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The connector module is segmented into independently replaceable functional units with standardized interfaces. Each unit (contact carrier, terminal, housing) can be independently removed and replaced through simple insertion and extraction actions, enabling easy repair and reuse without requiring complex disassembly procedures or additional connection mechanisms.

Inventive Principle:
Principle #1Segmentation
