Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for liquid pressure apparatuses can detect leakage but fail to notify states leading to leakage, making it difficult to accurately determine maintenance timing and prevent liquid leakage.
Innovation Solution
A monitoring system that includes a liquid pressure sensor, a display device, and a control device to determine the state of the apparatus as normal operation, maintenance, or stop of use, using lighting and sound alerts to notify users, and allowing for wireless communication between sensors and the control device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid leakage detection techniques are used, then liquid leakage can be detected, but the system cannot notify states leading to liquid leakage or accurately determine maintenance timing
Solution Approach 1:
The patent segments the monitoring system into multiple functional modules: liquid pressure sensor for pressure detection, control device for state determination, display device for visual notification, and sound generator for audible alerts. This segmentation allows each component to specialize in specific aspects of monitoring, enabling comprehensive detection of states leading to leakage while maintaining reliable leakage detection capability.
Solution Approach 2:
The system performs preliminary actions by detecting and notifying abnormal states (such as insufficient liquid level, high temperature, or clogging) before actual liquid leakage occurs. The control device determines apparatus states based on sensor signals and triggers advance warnings, allowing maintenance to be performed proactively rather than reactively after leakage happens.
2Device complexity
If only leakage detection is implemented, then the system remains simple, but maintenance timing cannot be accurately confirmed
Solution Approach 1:
The patent implements feedback mechanisms where the liquid pressure sensor continuously monitors pressure changes, the control device analyzes these changes to determine apparatus states, and the display device provides visual feedback about the current state. This closed-loop feedback system enables accurate determination of maintenance timing by providing continuous information about apparatus conditions without requiring complex manual inspection procedures.
Solution Approach 2:
The monitoring system performs self-service by automatically detecting abnormal states, determining apparatus conditions, and notifying users without requiring external intervention or complex manual assessment. The system serves itself by using its own sensor data to make state determinations and generate appropriate warnings, reducing the need for external monitoring resources.
3Loss of information
If multiple monitoring components are added to notify states leading to leakage, then maintenance timing can be determined accurately, but the device complexity increases
Solution Approach 1:
The patent applies multi-functionality by designing the control device to perform multiple functions: it receives signals from the liquid pressure sensor, determines various apparatus states (normal operation, maintenance needed, stop of use), controls the display device, and activates the sound generator. This universal control device reduces the need for separate dedicated components for each function, thereby limiting the increase in device complexity while still providing comprehensive state monitoring and notification.

AI summary
A liquid pressure apparatus monitoring system includes a liquid pressure apparatus, a liquid pressure sensor, a display device, a returning device, and a control device, in which the control device is configured to determine, in a first step, the state of the liquid pressure apparatus from states of normal operation, maintenance, and stop of use on the basis of a signal acquired from the liquid pressure sensor, and display, in a second step, on the display device, the state of the liquid pressure apparatus as the state of the normal operation, the maintenance, or the stop of use on the basis of a determination result of the first step.
