Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in properly setting and adjusting the mode of air compressors to match the operating conditions, leading to inefficient compression, increased wear on components, and reduced durability due to high pressure settings, and insufficient air supply when settings are too low.
Innovation Solution
An air compressor with a control unit that adjusts the motor start and stop pressure values based on detected pressure changes and usage conditions, reducing the driving time and load on the motor and tank units, and optimizing pressure levels to balance efficiency and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the use mode is set to a higher pressure mode to ensure sufficient compressed air supply, then the compressed air availability is improved, but the compression efficiency deteriorates and the motor unit operates longer with increased wear
Solution Approach 1:
The patent applies dynamics by making the pressure values (motor start pressure value and motor stop pressure value) changeable over time rather than fixed. The control unit automatically adjusts these pressure values based on the elapsed time since the last motor stop, allowing the system to adapt pressure settings dynamically. This resolves the contradiction by enabling the system to operate at lower pressures when possible (improving efficiency) while ensuring sufficient air supply is maintained through time-based pressure adjustments.
2Stability of the object's composition
If the use mode is set to a higher pressure mode to maintain tank pressure, then the compressed air reservoir is improved, but the motor unit driving time is extended and noise increases
Solution Approach 1:
The patent applies parameter changes by modifying the motor start and stop pressure values based on elapsed time. The control unit automatically changes these pressure parameters according to a predetermined time schedule, allowing the system to maintain adequate tank pressure while reducing motor operating time. This resolves the contradiction by dynamically adjusting pressure parameters to balance tank pressure stability with reduced motor runtime and noise.
3Quantity of substance
If the use mode is set to a higher pressure mode to ensure air supply, then the compressed air availability is improved, but high pressure load increases wear on components and reduces durability
Solution Approach 1:
The patent applies dynamics by implementing time-based automatic adjustment of pressure values. The control unit changes the motor start and stop pressure values based on elapsed time since the last motor stop, enabling the system to reduce pressure loads on components over time. This resolves the contradiction by dynamically lowering pressure settings after initial charging, ensuring sufficient air supply during operation while reducing high-pressure wear on the motor unit, tank, and compressor components, thereby improving durability.
4Adaptability or versatility
If multiple mode settings are provided to match different work conditions, then the adaptability is improved, but the ease of operation deteriorates due to difficulty in selecting the proper mode
Solution Approach 1:
The patent applies self-service by implementing automatic mode adjustment functionality. The control unit automatically changes the motor start and stop pressure values based on elapsed time without requiring user intervention. This resolves the contradiction by eliminating the need for users to manually select appropriate modes for different work conditions - the system automatically adapts its pressure settings over time, maintaining adaptability while significantly improving ease of operation.

AI summary
An air compressor includes a tank unit that stores compressed air, a motor unit that generates compressed air to be stored in the tank unit, a pressure detection unit that detects a pressure value in the tank unit, and a control unit that drives the motor unit when a pressure value in the tank unit detected by the pressure detection unit is equal to or less than a motor start pressure value, and stops the motor unit when the pressure value in the tank unit detected by the pressure detection unit is equal to or greater than a motor stop pressure value. The control unit changes at least either of the motor start pressure value or the motor stop pressure value every time when a predetermined time passed.
