Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressors face challenges in efficiently cooling their components due to restricted airflow, which limits the efficiency and performance of the compressor.
Innovation Solution
A compressor design featuring a stator assembly with partially open openings, an elongate central support body with aligned air inlet, and an annular airflow pathway, allowing axial and radial airflow to cool internal components effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a compressor is disassembled for maintenance or repair, then the valves can be accessed and replaced, but the compressor must be taken apart which increases complexity and time for maintenance
Solution Approach 1:
The valve assembly is nested within the compressor housing in a configuration that allows the valves to be accessed and removed through the same opening used for filling the refrigeration system, eliminating the need for separate disassembly steps while maintaining protective enclosure during operation
2Volume of moving object
If the compressor is designed with a compact structure, then space is saved, but the valves become difficult to access for maintenance
Solution Approach 1:
A removable valve assembly acts as an intermediary component that can be easily extracted through the fill opening, allowing maintenance access to valves without requiring additional openings or increasing the overall compressor volume, thus maintaining compactness while enabling easy repair
3Reliability
If the compressor housing is made robust and sealed, then reliability and protection are improved, but maintenance becomes more difficult
Solution Approach 1:
The valve assembly is designed to be pre-installed and sealed within the compressor housing, maintaining robust seal integrity during operation, while the entire valve assembly can be removed as a unit through the fill opening for maintenance, thus preserving reliability during use while enabling easy repair when needed
