Controlled Pressure Release System for Pressurized Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure relief systems in pressurized containers often activate at unpredictable pressures due to varying operating conditions, leading to potential over- or under-pressure issues, which can compromise safety and system reliability.
Innovation Solution
A controlled pressure release system featuring a non-reclosing pressure release device activated by a mechanism that responds to monitored operating conditions, using sensors to generate signals and a control system to trigger the release when predetermined limits are reached, ensuring precise pressure management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional pressure relief device is used, then pressure relief function is provided, but activation pressure is unpredictable due to varying operating conditions
Solution Approach 1:
The system incorporates sensors that continuously monitor operating conditions (temperature, pressure, flow rate) and feed this information to a controller. The controller adjusts the activation threshold dynamically based on real-time feedback, ensuring predictable and precise activation pressure despite varying operating conditions. This resolves the contradiction by making the activation pressure precise through active monitoring and adjustment.
Solution Approach 2:
The invention transitions from a static pressure relief device with fixed activation characteristics to a dynamic system where the activation threshold can be adjusted in real-time based on operating conditions. The controller modifies the activation criteria dynamically, allowing the system to maintain precise activation pressure prediction across different operating scenarios, thereby resolving the precision-reliability contradiction.
2Measurement precision
If a controlled activation system is implemented, then activation precision is improved, but device complexity increases
Solution Approach 1:
The controller serves multiple functions: it monitors operating conditions, determines activation timing, adjusts activation thresholds, and coordinates the pressure relief device operation. By making the controller a multi-functional component, the system achieves precise activation control without adding proportionally more complexity, as one component performs several critical functions simultaneously.
Solution Approach 2:
The invention merges the monitoring, control, and activation functions into an integrated system where sensors, controller, and pressure relief device work as a unified whole. This consolidation reduces overall system complexity compared to having separate independent systems for each function, while still achieving precise activation control through the coordinated interaction of combined components.

AI summary
A system for monitoring a pressurized container is provided. The system includes a non-reclosing pressure release device (12) and an activating mechanism (13) configured to open the non-reclosing pressure release device. The activating mechanism is activated by a control (50), based on a signal received by the control from a sensor (14). The activating mechanism may be selected from a group including actuators, pyrotechnic devices, and solenoids. The system may also include a non- reclosing pressure release device that may be configured to inject a fluid into the pressurized container. The activating mechanism may be operated by a trigger. The non-reclosing pressure release device may be designed to open automatically in the event that the activating mechanism fails to respond.
