Solution Overview

Problem

The existing modular industrial connectors have limited flexibility due to a restricted number of connector module slots in holding frames, which restricts their adaptability and requires increased assembly effort for customization.

Innovation Solution

The connector module is designed with at least two independent functional units that can operate independently and combine synergistically, featuring a cavity for reversible fixing using a cross-shaped fixing component, allowing for flexible assembly and replacement without increasing assembly effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of connector module slots in holding frames is increased to enhance flexibility and adaptability, then the modularity and customization capability are improved, but the device complexity and assembly effort increase

Engineering Contradiction:
Improveflexibility and adaptability of connectorVSAvoidassembly effort for customization
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connector module is divided into independent functional units that can be separately assembled and configured. Each functional unit represents a discrete segment that can be independently selected, removed, or replaced, allowing customization without increasing overall assembly complexity. The holding frame is also segmented into multiple slots that can accommodate different functional units.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The holding frame is designed with universal slots that can accommodate various types of functional units through standardized interfaces. This multi-functionality allows the same holding frame structure to support different connector configurations by simply changing the functional units inserted into the slots, rather than designing different frame structures for different applications.

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

2Adaptability or versatility

If connector modules are designed with multiple independent functional units to enhance modularity, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improvemodularity of connector moduleVSAvoidstructural complexity of connector module
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connector module is segmented into independent functional units, each performing a specific function. These units are structurally distinct and can be independently manufactured, tested, and replaced. The segmentation is achieved through separate housings or compartments within the connector module that physically isolate each functional unit.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple functional units are nested within a common connector module housing or holding frame. The functional units are arranged in a compact configuration where smaller units fit within or alongside larger structural elements, maximizing space utilization while maintaining independent accessibility to each unit.

Inventive Principle:
Principle #7Nested doll (Nesting)
