Solution Overview

Problem

Conventional air compressors face inefficiencies due to a single exit hole and valve mechanism, leading to increased resistance and motor overheating, as compressed air backforce restricts piston movement and reduces inflation speed.

Innovation Solution

The air compressor features a cylinder with multiple exit holes and air blocking walls, regulated by a control mechanism comprising plugs and compression springs, allowing smooth piston motion and efficient air transfer by restraining high-pressure air interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single exit hole is used in the cylinder, then the valve mechanism is simple, but the piston body cannot move smoothly due to increased resistance from compressed air backforce

Engineering Contradiction:
Improvesmooth piston motionVSAvoidvalve mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The single exit hole is segmented into multiple exit holes (first exit hole and second exit hole) in the cylinder. This segmentation allows compressed air to escape through multiple pathways simultaneously, reducing the backforce resistance on the piston body and enabling smoother reciprocating motion, while each hole maintains a relatively simple valve control structure.

Inventive Principle:
Principle #1Segmentation

2Productivity

If compressed air flows through the exit hole to enter the air storage container, then air storage is achieved, but the compressed air backforce restrains the plug and reduces inflation speed

Engineering Contradiction:
Improveinflation speedVSAvoidcompressed air backforce
Core Design Contradiction:
ProductivityVSForce

Solution Approach 1:

The air outlet is segmented into multiple exit holes with separate control mechanisms. This allows the total air flow to be distributed across multiple channels, reducing the force concentration on any single plug while maintaining high overall air transfer rate to the storage container, thereby increasing inflation speed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple exit holes act as intermediaries between the compression chamber and air storage container. By providing multiple parallel pathways for air flow, the system reduces the resistance force on individual control plugs while maintaining efficient air transfer, effectively mediating the conflict between air storage and inflation speed.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Power

If the piston body conducts reciprocating motion with high resistance, then air compression is achieved, but the motor becomes too hot and may burn out

Engineering Contradiction:
Improveair compression powerVSAvoidmotor temperature
Core Design Contradiction:
PowerVSTemperature

Solution Approach 1:

The exhaust system is segmented into multiple exit holes that operate in parallel. This segmentation reduces the backpressure resistance during the compression stroke, allowing the piston to complete reciprocating motion more efficiently with less motor load, thereby reducing motor temperature and preventing burnout while maintaining compression power.

Inventive Principle:
Principle #1Segmentation

AI summary

An improved air compressor generally includes a cylinder (2) fitted with a piston body (14), a main frame (11) for mounting a motor (12), and an air storage container (3). The cylinder (2) defines at its top wall (21) a plurality of exit holes (4, 5, 6), which are separated by a plurality of blocking walls (41, 51, 61) and regulated by a control mechanism. When the compressed air is produced in the cylinder (2) causing the control mechanism to open the exit holes (4, 5, 6), the instantaneous high-pressure air that flows through the exit holes can be restrained by the blocking walls to prevent the air from interfering with operation of the control mechanism, so that the piston body (14) can conduct reciprocating motion more smoothly and thus the performance of the air compressor can be increased.
