Solution Overview

Problem

Existing solid-state lighting systems face challenges with thermal management, including inefficient heat transfer and cumbersome replacement processes for LEDs or PCBs, which require skilled labor and can result in the entire PCB needing replacement if one LED malfunctions.

Innovation Solution

A socket assembly with a removable lighting package and integrated thermal management structure that engages a heat sink, allowing for efficient heat dissipation and easy replacement of lighting components without the need for additional thermal interfaces like grease or epoxy, featuring a socket housing with a receptacle and heat dissipating structure that can be mounted as a unit to the heat sink.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If LEDs are soldered down to a PCB and mechanically attached to a heat sink with thermal grease or epoxy, then thermal transfer can be achieved, but the thermal interface products are difficult to work with and do not provide sufficient heat transfer

Engineering Contradiction:
Improveheat transfer efficiencyVSAvoidease of thermal interface application
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

The invention extracts and eliminates the thermal interface product (thermal grease, thermal pad, or thermal epoxy) from the system by providing a lighting package with an integrated heat dissipating structure that directly engages the heat sink, removing the need for separate thermal interface materials while maintaining effective heat transfer

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention merges the lighting package with an integrated heat dissipating structure, combining the LED mounting function and thermal management function into a single unified component that directly interfaces with the heat sink

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If LEDs are soldered to a PCB that is mechanically attached to a heat sink, then the lighting system can be assembled, but the rework process is tedious and requires skilled labor when LEDs or PCB needs to be replaced

Engineering Contradiction:
Improvelighting system assembly stabilityVSAvoidease of LED or PCB replacement
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The invention segments the lighting system into a removable lighting package that can be independently replaced, separating the LED module with its integrated heat dissipating structure from the permanent heat sink and socket housing, enabling easy replacement without affecting the entire PCB or heat sink assembly

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention introduces dynamic replaceability to the lighting system by designing the lighting package with removable electrical and thermal connections, allowing the lighting package to be easily inserted and removed from the socket housing without permanent attachment

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the PCB includes many LEDs and is mechanically attached to a heat sink, then the lighting system can be configured, but if one LED malfunctions, the entire PCB may need to be replaced

Engineering Contradiction:
Improvelighting system configuration flexibilityVSAvoidease of individual LED replacement
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The invention segments the lighting system into individual replaceable lighting packages, each containing LEDs with their own integrated heat dissipating structures, allowing replacement of individual lighting packages rather than entire PCBs when LEDs malfunction

Inventive Principle:
Principle #1Segmentation
