Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust removal systems for laptops compromise visual aesthetics, impair fan performance, and violate safety regulations due to the placement of dust removing outlets on the housing, which also allow foreign matter entry.
Innovation Solution
A dustproof device incorporating a heat dissipating system with a fan set and heat dissipating fin, featuring a rotating section, guiding device, and indented section on the fin to direct dust out through an existing air outlet without additional external openings, maintaining safety compliance and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a dust removing outlet is disposed on the housing of a laptop, then dust can be removed from the laptop, but the overall visual aesthetics of the housing is spoiled
Solution Approach 1:
The dust removing outlet is extracted from the external housing and relocated to the internal heat dissipating fin structure. The indented section on the fin serves as the dust removal passage, separating the dust removal function from the external housing surface, thereby maintaining visual aesthetics while enabling dust removal capability.
Solution Approach 2:
The dust removal outlet is nested within the heat dissipating fin structure rather than being placed on the external housing. The indented section on the fin creates an internal passage that is concealed within the device structure, embedding the dust removal function inside the existing thermal management components.
2Object-generated harmful factors
If a dust removing hole is disposed on the housing of a fan apparatus, then dust can be removed, but the performance of the fan apparatus is greatly impaired
Solution Approach 1:
The dust removal function is merged with the heat dissipating fin structure. The same fin that performs thermal dissipation also incorporates the dust removal outlet through its indented section, combining two functions (heat dissipation and dust removal) into a single integrated component without compromising fan performance.
Solution Approach 2:
The heat dissipating fin is given multiple functions: it serves both as a thermal management component and as a dust removal structure. The indented section on the fin provides dust removal capability while the fin itself continues to perform heat dissipation, making the component universal and multi-functional.
3Object-generated harmful factors
If a dust removing outlet is disposed at the back of the housing near the fan apparatus, then dust can be removed, but foreign matters or fluid can easily get into the laptop and cause damage
Solution Approach 1:
The dust removal outlet is extracted from the external housing surface and relocated to the internal heat dissipating fin structure. This extraction removes the vulnerability point from the external housing, eliminating the security hole that would allow foreign matters or fluid to enter the laptop interior.
Solution Approach 2:
The heat dissipating fin structure acts as an intermediary between the internal fan apparatus and the external environment. The indented section on the fin provides a controlled dust removal passage that is mediated through the fin structure, preventing direct exposure of internal components to external contaminants.
4Object-generated harmful factors
If additional outlets are added to the housing for dust removal, then dust can be removed effectively, but the safety regulations for laptops are violated
Solution Approach 1:
The dust removal function is merged with the existing heat dissipating fin structure rather than adding separate outlets to the housing. By utilizing the fin structure itself as the dust removal passage, no additional external outlets are added, thus maintaining compliance with safety regulations while achieving effective dust removal.
Solution Approach 2:
The heat dissipating fin is given multiple functions: it serves both as a thermal management component and as a dust removal structure. This multi-functionality eliminates the need for additional dedicated dust removal outlets on the housing, thereby maintaining safety compliance while achieving dust removal capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively enhances fan performance, prevents foreign matter entry, and maintains the laptop's visual integrity by hiding the dust removal mechanism within the device, ensuring dust is expelled without external outlets.
Implementation Method 1
a fan set and a heat dissipating fin; wherein the fan set is disposed to provide heat dissipating wind force
Implementation Method 2
the heat dissipating fin is correspondingly disposed at the opening to conduct heat generated by the main computing unit out of the laptop by means of the heat dissipating wind force
Implementation Method 3
the fan set is disposed to provide heat dissipating wind force and dust removing wind force

AI summary
A dustproof device for laptops comprises a heat dissipating device disposed in a laptop to form a dustproof device for the same, wherein the heat dissipating device is disposed on a main computing unit in an interior of the laptop; the heat dissipating device includes a fan set and a heat dissipating fin. The fan set includes a housing, a rotating section and a guiding device, wherein on a lateral side of the housing is disposed an opening, the rotating section is disposed inside the housing, the guiding device is disposed inside the housing between the rotating section and a lateral side of the opening, and a dust removing path is formed between the guiding device and an inner wall surface of the housing adjacent to the guiding device. The heat dissipating fin is correspondingly disposed on the opening of the fan set, and an indented section is disposed in the heat dissipating fin in correspondence with the dust removing path to allow dust to be blown out of the laptop through the indented section while the laptop is performing dust removal without a need to dispose a dust removing hole on the housing of the laptop.
