Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressors in climate control systems often lack the capability for consistent and efficient operation of multiple compression mechanisms within a compact design, leading to inefficiencies in fluid circulation and cooling performance.
Innovation Solution
A co-rotating compressor with multiple independently operable compression mechanisms and motor assemblies, housed within a single shell assembly, which includes a partition defining separate suction and discharge chambers for each mechanism, allowing for independent operation and lubrication, and can be integrated into climate control systems for efficient fluid circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple compression mechanisms are integrated into a single compressor, then cooling performance and flexibility are enhanced, but device complexity increases
Solution Approach 1:
The compressor is divided into multiple independent compression mechanisms (first and second compression mechanisms) with separate motor assemblies, suction chambers, and discharge chambers. Each compression mechanism can operate independently to handle different refrigerant types and capacities, providing enhanced versatility while maintaining manageable complexity through modular design
Solution Approach 2:
The single compressor unit is designed to perform multiple functions by integrating different compression mechanisms that can handle different refrigerant types and cooling capacities. This multi-functional design allows the same device to adapt to various climate control requirements without needing separate compressors for different applications
2Volume of moving object
If multiple motor assemblies are integrated into a single shell, then compact design is achieved, but manufacturing complexity increases
Solution Approach 1:
Multiple motor assemblies (first and second motor assemblies) are merged into a single shell assembly, along with multiple compression mechanisms and associated chambers. This consolidation achieves a compact design by eliminating the need for separate compressor units, while the modular internal structure helps manage manufacturing complexity through standardized component integration
3Adaptability or versatility
If independent operation of compression mechanisms is enabled, then refrigerant type and capacity control is improved, but device complexity increases
Solution Approach 1:
The control system is segmented to allow independent operation of each compression mechanism through separate motor assemblies. Each motor assembly can be controlled independently to manage different refrigerant types and capacities, providing enhanced adaptability while keeping control complexity manageable through decentralized control architecture

AI summary
A compressor includes a shell (12), first (18) and second (25) compression mechanisms, first (20) and second (27) motor assemblies, first (34) and second (46) suction inlet fittings attached to the shell, and first (38) and second (50) discharge outlet fittings attached to the shell. The first and second compression mechanisms (18;25) are disposed within the shell. The first and second motor assemblies (20;27) are disposed within the shell, drive the first and second compression mechanisms (18;25), respectively, and are operable independently of each other. The first suction inlet fitting (34) provides fluid to the first compression mechanism (18). The first discharge outlet fitting (38) receives fluid compressed by the first compression mechanism (18). The second suction inlet fitting (46) provides fluid to the second compression mechanism (25). The second discharge outlet fitting (50) receives fluid compressed by the second compression mechanism (25).
