Solution Overview

Problem

In information handling systems, aligning connectors can be challenging, leading to misalignment issues that result in limited functionality, damage to connectors, and other components, especially in space-constrained environments where conventional guide pins are ineffective.

Innovation Solution

A connector alignment system featuring a base member with alignment channels and mounting features that include first and second alignment members with beveled edges to align connectors along multiple axes, ensuring precise alignment of connector pins and pads without the need for guide pins.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If guide pins are used to align connectors, then connector alignment is improved, but device height increases and space constraints are violated

Engineering Contradiction:
Improveconnector alignmentVSAvoiddevice height
Core Design Contradiction:
Manufacturing precisionVSLength of stationary object

Solution Approach 1:

The patent transitions from using guide pins that extend vertically (Z-dimension) to using alignment channels formed by alignment members that guide connectors horizontally (X-Y dimensions). The alignment members define channels that constrain connector movement in the horizontal plane, eliminating the need for vertical guide pins and thus reducing device height while maintaining alignment precision.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Manufacturing precision

If guide pins are used to align connectors, then connector alignment is improved, but connector damage risk increases when misalignment exceeds guide pin length

Engineering Contradiction:
Improveconnector alignmentVSAvoidconnector damage
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The alignment members act as intermediary structures that provide extended alignment guidance through defined channels. These channels guide the connectors along a controlled path, preventing direct contact between misaligned connector pins and pads. The alignment members mediate the alignment process, allowing connectors to be guided into proper alignment over a longer distance without risking damage to the actual connector contacts.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If conventional connector alignment methods are used, then alignment simplicity is maintained, but alignment precision deteriorates in space-constrained environments

Engineering Contradiction:
Improvealignment system simplicityVSAvoidconnector alignment precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The alignment system is segmented into multiple alignment members (first alignment member, second alignment member, third alignment member) that collectively define alignment channels. Each alignment member contributes to constraining connector movement in specific directions, creating a coordinated system that achieves high precision through distributed guidance rather than a single complex guide pin structure.

Inventive Principle:
Principle #1Segmentation

AI summary

A stacked connector alignment system includes a board with processor and a board connector coupled to the processor. An alignment element is mounted to the board adjacent the board connector. The alignment element includes first alignment members and second alignment members that are spaced apart from the first alignment members. A first component includes a primary first component connector and a secondary first component connector that is located on an opposite surface of the first component from the primary first component connector, and the first alignment members are configured to engage the first component to align the primary first component connector with the board connector. A second component includes a second component connector, and the second alignment members are configured to engage the second component to align the second component connector with the secondary first component connector when the primary first component connector is connected to the board connector.
