Solution Overview

Problem

The existing designs for pluggable connectors with different widths require distinct conductive parts, leading to residual clearance issues when used with connectors of different dimensions, which can cause disconnection of conductive wires from connection terminals.

Innovation Solution

The insulating body of the pluggable connector incorporates wedging means with a complementary shape to the connection terminal, allowing adaptation to varying dimensions and secure positioning within the housing, along with a movable plate to adjust for pitch compatibility with junction blocks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conductive parts with the same width are used for pluggable connectors of different widths, then productivity is improved by reducing the variety of conductive parts, but residual clearance is generated within the housing which can cause disconnection of conductive wires

Engineering Contradiction:
Improveproduction optimizationVSAvoidconnection reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent introduces a compensating element as an intermediary component between the conductive part and the housing. This compensating element fills the residual clearance space, maintaining reliable electrical connection while allowing the use of standardized conductive parts across different connector widths. The compensating element acts as a mediator that resolves the dimensional mismatch without requiring custom conductive parts for each connector size.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the physical state or dimensions of the compensating element to adapt to different clearance conditions. The compensating element can be deformable or adjustable, changing its parameters (such as thickness or shape) to match the specific residual clearance in different connector configurations, thereby maintaining reliable connections across various connector widths while using universal conductive parts.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If conductive parts are designed to fit tightly in narrow housings, then connection reliability is improved, but device complexity increases due to the need for different conductive parts for each insulating body width

Engineering Contradiction:
Improveconnection reliabilityVSAvoidvariety of conductive parts
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent makes the compensating element a universal component that can be used across different insulating body widths. Instead of designing specific conductive parts for each connector width, the same conductive part combined with the universal compensating element achieves reliable connections in all configurations. This multi-functional approach eliminates the need for multiple conductive part variants.

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

Solution Approach 2:

Instead of making the conductive parts adaptable to different housing widths (which would increase their complexity), the patent inverts the approach by making the compensating element adaptable. The compensating element absorbs the dimensional variations, allowing the conductive parts to remain simple and standardized while still achieving tight, reliable connections in all connector configurations.

Inventive Principle:
Principle #13The other way round (Inversion)

3Adaptability or versatility

If the housing dimensions are increased for wider pluggable connectors, then adaptability is improved to accommodate different connector widths, but residual clearance increases which may cause disconnection

Engineering Contradiction:
Improveconnector width adaptationVSAvoidwire connection stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The compensating element serves as an intermediary that bridges the gap between the standardized conductive part and the larger housing dimensions in wider connectors. It fills the increased residual clearance space, ensuring that the conductive wire remains securely connected to the connection terminal even in wider connector configurations, thereby maintaining reliability while enabling adaptability.

Inventive Principle:
Principle #24Intermediary (Mediator)
