Tamper-Proof Capsule for Tanker Fluid Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for preventing unauthorized liquid removal from tankers are inefficient and insecure, as they require extensive monitoring of multiple openings and seals, which can be manipulated, leading to unreliable detection of liquid theft.
Innovation Solution
A tamper-proof system where the volume measuring device and detector/separating device are housed in a lockable or non-destructively openable capsule with sensors to detect unauthorized access, preventing manipulation by ensuring only one seal needs to be monitored, and the introduction of air or water for falsification is detected and separated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple openings and seals of the tanker are monitored with sensors and satellite-based systems, then unauthorized liquid removal should be detected, but the system complexity and monitoring effort increase significantly and seals can still be manipulated
Solution Approach 1:
The patent extracts the critical measurement function from the complex tanker monitoring system by placing the volume measuring device and detector device in a sealed capsule that is part of the discharge line. This isolation means only the discharge line needs monitoring, not all tanker openings, thereby reducing system complexity while maintaining detection reliability.
Solution Approach 2:
The patent segments the monitoring system by creating a distinct sealed capsule containing the measurement devices. This segmentation allows the capsule to be monitored independently as a single unit rather than requiring monitoring of multiple separate openings and seals throughout the tanker system.
2Reliability
If seals and sensors are installed on all tanker openings for monitoring, then unauthorized access should be detected, but the seals themselves can be manipulated and traceability becomes unrealistic with multi-shift operation
Solution Approach 1:
The patent removes the need for monitoring multiple tanker openings by extracting the measurement function into a sealed capsule on the discharge line. This single-point monitoring approach maintains security while dramatically reducing the monitoring effort and improving traceability, especially in multi-shift operations.
3Measurement precision
If air or water is introduced into the line system to manipulate meter readings, then false volume measurements are produced, but extensive monitoring of all openings is required to detect this
Solution Approach 1:
The patent uses the sealed capsule as an intermediary that isolates the measurement devices from potential manipulation at the tanker opening. The capsule seal acts as a barrier that prevents introduction of air or water into the measurement system, protecting measurement accuracy without requiring complex monitoring of all system openings.
Solution Approach 2:
The capsule combines multiple functions (sealing, housing measurement devices, providing structural support) into a single integrated component. This composite structure provides inherent protection against manipulation while maintaining measurement precision, reducing the need for additional monitoring complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach significantly enhances security against liquid theft by ensuring unauthorized removal can be traced and proven, reducing monitoring effort and preventing manipulation, as the capsule's secure design prevents tampering with the measuring system.
Implementation Method 1
at least one detector device for detecting gas inclusions in the liquid flowing through the dispensing line
Implementation Method 2
at least one separating device for separating gas inclusions in the liquid flowing through the dispensing line

AI summary
The system has a dispensing line connected with an outlet valve of a chamber of the tanker. A dispensing valve is arranged at the end of the dispensing line for dispensing of fluid from the chamber over the outlet valve. The fluid flows through the dispensing line. A volume measuring device (42) is provided for measuring the fluid volume dispensed over the dispensing line. A detection device (40) detects the gas inclusion in the fluid flowing through the dispensing line. The volume measuring device and the detection device are arranged in a sealable capsule (12).
