Solution Overview

Problem

Existing compressors face challenges with compact design, increased manufacturing costs, and maintenance complexity due to multiple discharge valves, which affect cooling power and noise reliability, especially in variable speed operations.

Innovation Solution

A compressor design featuring a plurality of compact, integral discharge valves that control gas discharge through multiple ports, reducing occupied area and manufacturing costs, while optimizing compression efficiency and noise by sequentially opening and closing valves based on pressure and speed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single discharge hole and discharge valve are used, then the compressor structure is simple, but the occupied area increases and compact design becomes difficult

Engineering Contradiction:
Improvestructure simplicityVSAvoidoccupied area
Core Design Contradiction:
Device complexityVSArea of moving object

Solution Approach 1:

The single discharge valve is segmented into multiple discharge valves (first discharge valve and second discharge valve), each corresponding to different discharge ports. This segmentation allows the valves to be arranged in a compact configuration, reducing the overall occupied area while maintaining structural simplicity through the integrated valve body design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The discharge ports are arranged in different spatial dimensions (first discharge port in first direction, second discharge port in second direction perpendicular to the first). This dimensional arrangement allows multiple discharge valves to be positioned without increasing the occupied area in any single plane, enabling compact compressor design.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If multiple discharge holes and discharge valves are installed individually, then the discharge control is improved, but the manufacturing cost increases

Engineering Contradiction:
Improvedischarge controlVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Multiple discharge valves are merged into a single integrated valve body structure, where the first discharge valve and second discharge valve are formed as one piece. This merging reduces the number of separate components, simplifies manufacturing processes, and lowers production costs while maintaining the ability to control discharge through multiple ports.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated valve body serves multiple functions simultaneously: it houses both the first discharge valve and second discharge valve, provides sealing surfaces for both valves, and manages discharge through multiple ports. This multi-functionality reduces the overall component count and manufacturing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple discharge holes and discharge valves are installed individually, then the discharge control is improved, but the maintenance complexity increases

Engineering Contradiction:
Improvedischarge controlVSAvoidmaintenance complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of repair

Solution Approach 1:

The first discharge valve and second discharge valve are merged into a single integrated component, reducing the number of parts that need to be handled during maintenance. This merging simplifies assembly and disassembly procedures, making the compressor easier to maintain while preserving multiple discharge control capabilities.

Inventive Principle:
Principle #5Merging (Combining)

4Productivity

If the discharge hole size is enlarged to secure flow rate, then the flow resistance is reduced, but the dead volume increases and cooling power decreases

Engineering Contradiction:
Improveflow rateVSAvoidcooling power
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The single large discharge hole is segmented into multiple smaller discharge ports (first discharge port and second discharge port). This segmentation maintains adequate flow rate through the combined area of multiple ports while reducing the dead volume associated with a single large hole, thereby preserving cooling power.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple discharge ports are arranged in different spatial directions (first direction and second direction perpendicular to the first). This dimensional distribution allows the compressor to achieve adequate flow rate through distributed openings rather than a single large hole, reducing dead volume while maintaining productivity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

5Productivity

If the discharge valve size is increased to reduce flow resistance, then the flow rate is improved, but the noise increases due to increased impact

Engineering Contradiction:
Improveflow rateVSAvoidnoise
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The single large discharge valve is segmented into multiple smaller discharge valves (first discharge valve and second discharge valve). This segmentation reduces the impact force on each individual valve, thereby reducing noise from valve closure while maintaining adequate flow rate through the combined area of multiple valves.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple discharge valves are positioned in different spatial directions, allowing the impact forces to be distributed rather than concentrated on a single large valve. This dimensional distribution reduces the noise generated by valve impact while preserving the overall flow rate capability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
