Solution Overview

Problem

Existing electrical connector systems require separate sets of connectors for straight and ninety-degree connections, increasing manufacturing costs due to the need for distinct tooling for each configuration.

Innovation Solution

A dual-configurable electrical connector system featuring a male connector with a U-shaped shroud and a female connector with adaptable terminal openings, allowing for both parallel and perpendicular mating configurations using a resilient lock tab and cantilever beam mechanism, which secures the connectors in both orientations with a single set of manufacturing tools.

VSEngineering Contradiction Analysis

1Reliability

If separate sets of connectors are used for straight and ninety-degree connections, then connector reliability is improved, but manufacturing cost increases

Engineering Contradiction:
Improveconnector reliabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The connector is designed with a universal structure that can perform both straight and ninety-degree connections through a single component design. The female connector body includes terminal openings that can accommodate male terminals in both parallel and perpendicular orientations, eliminating the need for separate connector sets and reducing manufacturing costs while maintaining connection reliability

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

2Stability of the object's composition

If separate sets of connectors are used for straight and ninety-degree connections, then connection stability is improved, but device complexity increases

Engineering Contradiction:
Improveconnection stabilityVSAvoidconnector system complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

A single female connector design incorporates terminal openings that accept male terminals in both parallel and perpendicular configurations, reducing the overall system complexity by eliminating the need for multiple specialized connector sets while maintaining stable connections through a unified locking mechanism

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

Solution Approach 2:

The connector employs a resilient lock tab that can dynamically adapt to secure the male connector in either parallel or perpendicular orientation. The lock tab's flexible nature allows it to engage with the shroud in multiple configurations, providing stable connection across different orientations without requiring separate rigid structures

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If a single set of connectors is used for both straight and ninety-degree connections, then manufacturing cost is reduced, but adapter complexity increases

Engineering Contradiction:
Improvemanufacturing costVSAvoidadapter structure complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The female connector is divided into functional segments including a connector body, terminal openings, and a locking mechanism with resilient lock tabs. This segmentation allows each component to be optimized for its specific function while working together to achieve multi-configuration capability, reducing overall complexity compared to a monolithic design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The terminal openings in the female connector body are designed with asymmetric geometry that can accommodate male terminals in both parallel and perpendicular orientations. The shroud and lock tab also feature asymmetric designs that enable selective engagement in different configurations, reducing the need for symmetric but overly complex structures

Inventive Principle:
Principle #4Asymmetry

4Ease of operation

If a resilient lock tab mechanism is used, then ease of operation is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improveconnector engagement easeVSAvoidlock tab aperture precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The lock tab and lock aperture are designed with specific dimensional parameters and tolerances that balance ease of operation with manufacturing precision. The resilient lock tab's deflection characteristics and the aperture's geometry are optimized to provide clear tactile feedback during engagement while accommodating normal variations in manufacturing, reducing the stringency of precision requirements

Inventive Principle:

AI summary

An electrical connector system (200) having a male and female connector (202, 204). The male connector (202) includes a u-shaped shroud (208) axially surrounding a male terminal (206) having an opening generally perpendicular to the male terminal's longitudinal axis. The female connector (202) includes a female terminal (216) having two openings, one generally parallel with the female terminal's longitudinal axis and another generally perpendicular to that axis. The male and female terminals (116) mate in a parallel configuration having the male terminal axis generally parallel to the female terminal axis or in a perpendicular configuration having the male terminal axis generally perpendicular to the female terminal axis. A connector body holds the female terminal (216). The connector body (230) defines a locking means that releasably secures the connector body (230) to the shroud (208) in both the parallel and perpendicular mating configurations. The locking means may include a triangular shaped lock tab (242) that engages a similarly shaped lock aperture (236).
