Gas Compressor Handle Protection for Unobstructed Cooling Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas compressors face issues with air vent damage due to impacts, leading to reduced strength and decreased cooling efficiency when the slit openings are reduced to enhance protection.
Innovation Solution
A gas compressor design featuring a handle portion with protective elements that cover the air vents, maintaining airflow while enhancing structural integrity and preventing direct impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the opening area of the slit is reduced to increase thickness and improve strength, then the strength of the cover portion is improved, but the cooling efficiency is decreased
Solution Approach 1:
The cover portion is divided into multiple regions: the air vent region with slits for cooling, and the protective portion with increased thickness for strength. This segmentation allows each region to optimize its function without compromising the other.
Solution Approach 2:
The protective portion is provided with a locally increased thickness specifically at regions requiring impact resistance, while the air vent slits maintain their original opening area for optimal cooling. This local quality enhancement resolves the contradiction by applying structural reinforcement only where needed.
2Strength
If the air vent is directly reinforced to protect from impacts, then the strength is improved, but the airflow is blocked and cooling efficiency is reduced
Solution Approach 1:
The air vent structure is segmented into the vent slits for airflow and the protective portion for strength. The protective portion is positioned adjacent to but separate from the slits, ensuring airflow paths remain unobstructed while providing impact protection.
Solution Approach 2:
The protective portion acts as an intermediary element that absorbs impacts before they reach the air vent slits. It is positioned as a buffer zone with increased thickness that deflects or absorbs external forces without interfering with the airflow through the slits.

AI summary
A gas compressor includes a main body portion including a compression unit configured to compress gas, an air blowing unit, and a drive unit configured to drive the compression unit and the air blowing unit, a cover portion covering at least a part of the main body portion and having an air vent through which air flows from the air blowing unit, and a handle portion having a gripping portion. The air vent faces a rotation axis direction of a rotation member of the air blowing unit which is rotated by being driven by the drive unit, and the handle portion includes a protective portion facing the air vent and being apart from the air vent.
