Solution Overview

Problem

Conventional cooling devices for mobile electronic devices often compromise portability and stability due to their mounting-type structure, which can lead to inefficient cooling and increased battery consumption, especially when handling high-processing tasks, and wired charging further limits mobility.

Innovation Solution

A cooler with a housing structure that optimizes airflow from the processor to a fan assembly for efficient cooling, while providing a mounting system that absorbs external impacts and includes a separate battery for wireless charging, maintaining device stability and mobility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a mounting-type cooling device is used for mobile electronic devices, then cooling function is provided, but portability is deteriorated

Engineering Contradiction:
Improvecooling efficiencyVSAvoidportability
Core Design Contradiction:
TemperatureVSWeight of moving object

Solution Approach 1:

The patent combines multiple functions (cooling, charging, and portable power supply) into a single integrated device. The cooling device includes a battery that can charge the mobile electronic device wirelessly, eliminating the need for separate cooling accessories and wired charging cables, thus improving portability while maintaining cooling efficiency.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cooling device is designed with multi-functionality: it provides cooling through a fan, charges the mobile device wirelessly through a charging coil, and can also serve as a portable power supply. This universal design reduces the number of separate accessories needed, improving portability without sacrificing cooling performance.

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

2Temperature

If air is blown toward the rear surface of the mobile electronic device, then cooling is provided, but cooling efficiency is insufficient

Engineering Contradiction:
Improvecooling functionVSAvoidcooling efficiency
Core Design Contradiction:
TemperatureVSProductivity

Solution Approach 1:

The patent introduces a fluid channel that directs air flow specifically to the processor area, which is the primary heat-generating component. This localized cooling approach improves cooling efficiency by concentrating cooling effort where it is most needed, rather than simply blowing air across the entire rear surface.

Inventive Principle:
Principle #3Local quality

3Use of energy by moving object

If wired charging is used to alleviate battery consumption, then battery life is extended, but mobility is reduced

Engineering Contradiction:
Improvebattery lifeVSAvoidmobility
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The patent replaces the mechanical wired charging system with a wireless charging system using electromagnetic induction. The cooling device includes a charging coil that wirelessly transfers power to the mobile device, eliminating the need for physical cable connections and maintaining mobility while extending battery life.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If conventional mounting structure is used, then device is held, but stability is insufficient

Engineering Contradiction:
Improveholding functionVSAvoidholding stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent incorporates a shock-absorbing structure in the mounting mechanism that cushions external impacts before they reach the mobile electronic device. This beforehand cushioning protects the device from shocks and vibrations, improving holding stability during portable use.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
