Solution Overview

Problem

Existing surface-mounted electrical connectors have a high profile that obstructs light emission in LED devices and are not suitable for densely packed electronic components, necessitating a connector with a smaller height profile.

Innovation Solution

A connector assembly with a housing and contact that protrudes through a substrate from both sides, allowing for a low profile design by positioning the mating interface either flush or recessed within the substrate, thereby minimizing the height above the substrate and avoiding obstruction of light emission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If traditional surface-mounted connectors are used, then electrical connection functionality is achieved, but the connector height profile becomes too large and obstructs light emission from LEDs

Engineering Contradiction:
Improvelight emissionVSAvoidconnector height profile
Core Design Contradiction:
Illumination intensityVSLength of stationary object

Solution Approach 1:

The connector housing is inverted to extend downward through the circuit board rather than upward from it. This inversion allows the mating interface to be positioned at or below the circuit board surface, eliminating the height profile problem that obstructs LED light emission while maintaining electrical connection functionality.

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

Solution Approach 2:

The connector design transitions from a vertical profile extending above the circuit board to a horizontal profile extending through the board thickness. By changing the primary dimension of connector extension from vertical (above board) to horizontal (through board), the solution eliminates interference with LED light emission above the board surface.

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

2Productivity

If traditional connectors protruding from the circuit board are used, then electrical connections are established, but the connector height interferes with densely packed electronic components

Engineering Contradiction:
Improvecomponent densityVSAvoidconnector height profile
Core Design Contradiction:
ProductivityVSLength of stationary object

Solution Approach 1:

By inverting the connector housing to extend downward through the circuit board instead of upward, the design eliminates vertical space conflicts that would prevent dense component packing. The mating interface positioned at or below the board surface allows components to be placed in the previously occupied vertical space.

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

Solution Approach 2:

The connector extends in the horizontal dimension through the board thickness rather than occupying vertical space above the board. This dimensional reconfiguration enables increased component density by freeing up the vertical space above the circuit board for other electronic components.

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

3Length of stationary object

If the connector housing extends through the substrate, then the profile height is reduced, but the housing protrudes from both sides of the substrate requiring dual-sided mounting

Engineering Contradiction:
Improveconnector profile heightVSAvoidmounting complexity
Core Design Contradiction:
Length of stationary objectVSDevice complexity

Solution Approach 1:

The connector housing integrates multiple functions into a single component: it provides structural support, establishes electrical connections through the substrate, and positions the mating interface. This merging of functions into one inverted housing structure simplifies the overall assembly despite the through-substrate configuration.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The inverted connector housing serves multiple purposes simultaneously: it acts as the connector body, provides the mounting structure for electrical contacts, defines the mating interface location, and anchors the assembly to the substrate. This multi-functionality reduces the need for separate components and simplifies the mounting process.

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

AI summary

A connector assembly includes a housing and a contact. The housing extends from a front end to an opposite back end. The housing includes an interior chamber inwardly extending from the front end that is configured to receive a mating connector through the front end of the housing. The contact is joined with the housing and extends between a mating end and a mounting surface. The mating end is configured to engage a mating contact of the mating connector. The mounting surface is configured to be mounted to a substrate to electrically couple the mating connector with the substrate. The housing extends through an opening in the substrate such that the housing protrudes from opposite sides of the substrate.
