Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressors fail to effectively reduce both noise and temperature of intake air.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a package compressor design is used to reduce part arrangement restrictions and improve productivity, then manufacturing efficiency is improved, but noise and temperature of intake air cannot be effectively reduced
Solution Approach 1:
The housing is divided into multiple chambers (machine chamber, A-chamber, B-chamber) separated by partitions (A-partition, B-partition). This segmentation allows independent optimization of each chamber's function - the machine chamber houses noisy components while A and B chambers manage air intake and cooling separately, enabling noise reduction without compromising manufacturing efficiency
Solution Approach 2:
The A-partition with A-vent and B-partition act as intermediary structures between the machine chamber and external environment. These partitions with controlled vents serve as mediators that filter and direct air flow, reducing noise transmission while maintaining proper intake air temperature and flow to the compressor body
2Temperature
If cooling air is introduced to reduce temperature, then cooling effect is improved, but noise of intake air increases
Solution Approach 1:
The air intake and cooling functions are segmented into separate chambers (A-chamber for air intake, machine chamber for cooling). The A-partition with A-vent separates the air intake path from the machine chamber, allowing cool air to be supplied to the compressor body while preventing noise from the motor and compressor components from contaminating the intake air
Solution Approach 2:
The A-partition serves as an intermediary barrier between the external air intake environment and the noisy machine chamber. The A-vent in the A-partition acts as a controlled interface that allows thermal exchange (cooling) while blocking acoustic transmission (noise reduction)
