Solution Overview

Problem

Power sockets with USB ports often experience local overheating due to component size and arrangement limitations, restricting the increase in carried wattage and potentially leading to component damage.

Innovation Solution

A socket structure combining a metallic frame and casing enhances thermal conductivity by conducting heat to the exterior, using a metallic frame with extending portions and a heat conducting component to improve heat dissipation, thereby addressing local overheating and enabling higher power handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If USB ports are added to power sockets to meet market requirements for charging, then the functionality and market competitiveness are improved, but local overheating occurs due to component arrangement limitations

Engineering Contradiction:
ImprovefunctionalityVSAvoidlocal overheating
Core Design Contradiction:
Adaptability or versatilityVSTemperature

Solution Approach 1:

The power socket is divided into multiple independent cavity modules, each housing specific components. This segmentation allows heat to be distributed across multiple smaller areas rather than concentrated in one location, reducing local overheating while maintaining USB charging functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A metal frame structure is introduced as an intermediary thermal conduction path between the internal components (USB ports, circuitry) and the external environment. The metal frame acts as a heat sink and thermal highway, efficiently transferring heat away from sensitive components to prevent overheating.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Power

If the total wattage of power sockets is increased to meet rising power requirements, then the power delivery capability is improved, but overheating and component damage risk increase

Engineering Contradiction:
Improvetotal wattageVSAvoidcomponent damage risk
Core Design Contradiction:
PowerVSReliability

Solution Approach 1:

The metal frame serves as a thermal intermediary that intercepts heat generated by high-power components before it can damage them. This allows the socket to safely handle higher wattages by providing a dedicated heat evacuation pathway.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Different regions of the socket are designed with different thermal properties - high-heat areas near USB ports and high-wattage components are strategically positioned adjacent to metal frame structures that provide superior thermal conduction, while other areas use different materials optimized for their specific functions.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If more components are arranged in limited space to increase functionality, then the charging capability is improved, but heat dissipation becomes insufficient

Engineering Contradiction:
Improvecharging capabilityVSAvoidheat dissipation efficiency
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

Multiple USB ports and charging components are segmented into separate cavities, each with its own thermal management approach. This prevents heat accumulation in a single concentrated area and allows each component to dissipate heat more effectively.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The metal frame extends heat dissipation from the two-dimensional component layout into the third dimension by providing vertical thermal conduction paths through the socket structure, allowing heat to escape in multiple directions rather than being trapped in the planar component arrangement.

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