Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single discharge port and discharge valve are used, then the compressor structure is simple, but the discharge flow resistance increases and cooling power decreases
Solution Approach 1:
The single discharge port is divided into multiple discharge ports (first discharge port and second discharge port), and the single discharge valve is divided into multiple discharge valves (first discharge valve and second discharge valve). This segmentation allows the compressed gas to be discharged through multiple pathways simultaneously, reducing discharge flow resistance and improving cooling power while maintaining a relatively simple overall structure.
2Productivity
If multiple discharge ports and discharge valves are used, then the discharge flow resistance decreases, but the occupied area increases and compact design becomes difficult
Solution Approach 1:
The first discharge valve and second discharge valve are arranged in a nested or overlapping configuration where the valve bodies share common structural elements and mounting space. The discharge ports are positioned to utilize the same cylindrical space around the piston, allowing multiple valves to coexist in a compact arrangement that minimizes the overall occupied area while maintaining effective discharge flow paths.
3Productivity
If multiple discharge valves are individually installed, then the discharge control is improved, but the manufacturing cost increases
Solution Approach 1:
The first discharge valve and second discharge valve are combined into a single integrated valve assembly that is manufactured as one piece or pre-assembled unit. This merging of multiple valve functions into a single component reduces the number of separate parts that need to be manufactured, stored, and installed individually, thereby reducing manufacturing cost while maintaining the discharge control benefits of having multiple valves.
4Productivity
If multiple discharge valves are individually installed, then the discharge control is improved, but the maintenance convenience decreases
Solution Approach 1:
By combining the first discharge valve and second discharge valve into a single integrated assembly, the maintenance convenience is improved. Instead of needing to handle, test, and reinstall multiple separate valve components, the technician can service the discharge valve system as one unit. The integrated design allows for easier removal, inspection, and replacement of the entire valve assembly, reducing maintenance time and complexity while preserving the multi-valve discharge control functionality.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves a compact compressor with reduced manufacturing and maintenance costs, improved compression efficiency, and enhanced reliability by minimizing the area occupied by discharge valves and optimizing their operation.
Implementation Method 1
both ends of the discharge valve may be fixed, and the other end thereof may be a free end. Accordingly, the discharge valve may elastically deform to open and close the discharge port

AI summary
The disclosure relates to a compressor that has a plurality of discharge ports and discharge valves disposed in each of the discharge ports. The compressor includes: a compression cylinder configured to have a plurality of discharge ports for discharging compressed gas provided in a predetermined direction; and a plurality of discharge valves configured to be provided in the plurality of discharge ports to control an amount of discharged gas, in which each of the discharge valves includes: a valve neck configured to have one end fixed in a plate shape having elasticity and extend along an arrangement direction of the plurality of discharge ports from the one end; and a valve head configured to be provided at the other end of the valve neck to cover each of the discharge ports. According to the compressor of the disclosure, it is possible to manufacture the compressor compactly and reduce manufacturing and maintenance costs of the compressor by reducing the area occupied by the plurality of discharge valves.
