Solution Overview

Problem

Existing electrical connector systems face challenges in efficiently supporting multiple connectors on a common printed circuit board while maintaining secure connections and efficient electrical communication.

Innovation Solution

The electrical connector assembly comprises a first connector mounted to a substrate with electrical contacts and a second connector supported by the first connector, secured to the substrate without direct electrical contact, allowing for secure attachment and efficient communication through a dielectric or insulative housing and engagement members.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple electrical connectors are mounted on a common printed circuit board, then electrical communication efficiency is improved, but connection stability deteriorates due to gravitational forces and alignment issues

Engineering Contradiction:
Improveelectrical communication efficiencyVSAvoidconnection stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The connector assembly is divided into separate components: a first connector mounted on the substrate, a second connector supported by the first connector, and independent engagement members. This segmentation allows each component to be optimized for its specific function while working together as a cohesive system, resolving the contradiction between supporting multiple connectors and maintaining connection stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The engagement members are designed to resist gravitational forces and maintain alignment between connectors. The latch assembly and complementary latch features create counteracting forces that prevent misalignment and ensure stable connections, directly addressing the reliability issue caused by gravity.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

2Strength

If connectors are directly secured to the substrate, then connection strength is improved, but device complexity increases due to additional mounting requirements

Engineering Contradiction:
Improveconnection strengthVSAvoidmounting complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The second connector is supported by the first connector, creating a nested arrangement where the second connector is held by the first connector rather than requiring direct substrate mounting. This nesting reduces mounting complexity while maintaining connection strength through the engagement members that secure the nested structure.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The first connector serves multiple functions: it provides electrical connection, supports the second connector mechanically, and works with engagement members to secure both connectors to the substrate. This multi-functionality reduces the need for separate mounting mechanisms, simplifying the overall device while maintaining strength.

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

3Ease of operation

If connectors are designed for easy attachment and detachment, then ease of operation is improved, but connection reliability deteriorates

Engineering Contradiction:
Improveattachment easeVSAvoidconnection reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The latch assembly incorporates movable components that transition between engaged and disengaged states. The latch member can move to lock the connectors together securely, while also allowing easy release when needed. This dynamic design provides both ease of operation and reliable connection through the same mechanism.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The engagement members and latch assembly provide mechanical feedback that confirms proper engagement. When connectors are correctly attached, the latch features engage and provide tactile or visual confirmation, ensuring reliability. The same mechanism allows easy detachment when the latch is released, maintaining ease of operation.

Inventive Principle:
Principle #23Feedback

AI summary

Methods and apparatus are disclosed for supporting first and second electrical connectors on a substrate. For instance, the first electrical connector includes electrical contacts that are configured to be mounted to the substrate. The second electrical connector includes electrical contacts that are configured to be mounted to a complementary electrical component other than the substrate. The second electrical connector is thus configured to be attached to the first electrical connector, such that the second electrical is supported by the substrate without being mounted to the substrate.
