Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in properly determining and selecting mode settings for air compressors, often setting them to higher modes to ensure sufficient compressed air, leading to reduced compression efficiency, increased motor and component wear, and noise, while lower modes result in insufficient air supply when needed.
Innovation Solution
An air compressor with a pressure detection unit and control unit that dynamically adjusts the motor start and stop pressure values based on usage conditions, reducing the pressure in the tank unit and optimizing motor operation to balance efficiency and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the use mode is set to a higher mode (high pressure mode or ultra-high pressure mode) to ensure sufficient compressed air supply, then the compressed air supply is sufficient, but the compression efficiency is reduced, motor operation time is extended, and component wear increases
Solution Approach 1:
The patent implements dynamic adjustment of motor start and stop pressure values based on actual usage conditions. The control unit monitors the operation history and compressed air consumption patterns, then dynamically modifies the pressure thresholds to optimize compression efficiency while ensuring adequate air supply. This resolves the contradiction by making the system adaptive rather than static.
Solution Approach 2:
The patent changes the operational parameters (motor start pressure value and motor stop pressure value) based on usage conditions. When usage indicates lower demand, the system lowers these pressure thresholds, reducing the pressure range the compressor must maintain, thereby improving compression efficiency while still meeting actual air supply needs.
2Quantity of substance
If the use mode is set to a higher mode to maintain high pressure in the tank unit, then the compressed air supply is sufficient, but the motor operation duration is extended and driving sound increases
Solution Approach 1:
The control unit adjusts the motor start and stop pressure values based on monitored usage conditions. When the system detects lower compressed air consumption or longer intervals between usage, it reduces the pressure thresholds, thereby shortening the motor operation duration while maintaining sufficient air supply for actual needs.
Solution Approach 2:
The system monitors its own usage patterns and automatically adjusts operational parameters without user intervention. By tracking compressed air consumption and operation history, the system self-optimizes the pressure thresholds to minimize motor runtime while ensuring adequate air supply.
3Quantity of substance
If the use mode is set to a higher mode to keep pressure in the tank unit high, then the compressed air supply is sufficient, but high pressure load is applied to components leading to reduced durability
Solution Approach 1:
The patent dynamically changes the motor start and stop pressure values based on actual usage conditions. When usage patterns indicate lower demand, the system lowers these pressure thresholds, reducing the maximum pressure to which components are subjected, thereby improving durability while maintaining sufficient air supply for actual operational needs.
4Productivity
If the use mode is set to a lower mode (low pressure mode or normal pressure mode) to improve compression efficiency, then the compression efficiency is improved, but the compressed air becomes rapidly insufficient when pressure is lowered by using the driving tool
Solution Approach 1:
The system dynamically adjusts the motor start and stop pressure values based on real-time usage conditions. When compressed air consumption increases or usage frequency rises, the system raises the pressure thresholds to ensure adequate air supply, preventing the rapid insufficiency that would occur with fixed lower pressure settings.

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.
