Clutch-Type Air Compressor Intake Switching for Displacement and Fuel Use

Solution Overview

Problem

Conventional clutch-type air compressors face challenges with small displacement and large size, leading to space and weight issues, while consuming engine power and increasing fuel consumption due to reliance on supercharged intake pipelines.

Innovation Solution

A clutch-type air compressor system with an intake port connected to both natural aspiration and supercharged intake pipelines, controlled by an intake control valve to switch between modes, allowing efficient air intake based on engine speed, thereby optimizing displacement, size, and energy consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a clutch-type air compressor uses naturally aspirated mode to draw air from the atmosphere, then energy consumption is reduced and engine power is saved, but the displacement becomes small requiring bipolar compression which increases size and weight

Engineering Contradiction:
Core Design Contradiction:
Use of energy by moving objectVSVolume of moving object

Solution Approach 1:

The air compressor system is designed to perform multiple functions by switching between two intake modes: naturally aspirated mode for energy saving and supercharged intake mode for large displacement requirements. The same compressor unit can adapt to different operational needs, achieving both small size/low energy consumption and large displacement as needed.

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

Solution Approach 2:

The system dynamically switches between naturally aspirated and supercharged intake modes based on real-time engine operating conditions. The control unit monitors engine speed, load, and air demand to determine the optimal intake mode, making the system adaptable rather than static.

Inventive Principle:
Principle #15Dynamics

2Quantity of substance

If a clutch-type air compressor uses bipolar compression to increase displacement, then the displacement demand is met, but the size and weight increase which is not conducive to space arrangement

Engineering Contradiction:
Core Design Contradiction:
Quantity of substanceVSVolume of moving object

Solution Approach 1:

The system achieves large displacement requirements without bipolar compression by switching to supercharged intake mode when needed. The same compressor can operate in naturally aspirated mode for normal conditions, eliminating the need for complex bipolar compression mechanisms and their associated space requirements.

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

Solution Approach 2:

A supercharger is introduced as an intermediary device to provide pressurized air to the compressor during high-demand situations. This external assistance allows the compact compressor to achieve large effective displacement without requiring the compressor itself to be physically larger or use bipolar compression.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Quantity of substance

If a conventional air compressor draws air from the supercharged intake pipeline, then large displacement is achieved, but engine power is consumed resulting in high fuel consumption

Engineering Contradiction:
Core Design Contradiction:
Quantity of substanceVSLoss of energy

Solution Approach 1:

The system dynamically selects the intake source based on engine operating conditions. During normal operation, it switches to naturally aspirated mode to avoid consuming engine power. The control unit continuously monitors conditions and transitions to supercharged intake only when large displacement is critically needed, minimizing energy loss.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system employs periodic switching between naturally aspirated and supercharged intake modes based on cyclical engine load variations. By alternating between low-energy and high-performance modes according to actual demand, the system reduces overall energy consumption while maintaining adequate displacement when required.

Inventive Principle:
Principle #19Periodic action
