Tamper-Proof Sensor Mounting for Container Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sensors mounted inside or outside containers for detecting process variables face challenges in easy and flexible installation, and existing solutions do not adequately prevent manipulation or contamination during the refilling process, especially in applications like Adblue containers.
Innovation Solution
A tamper-proof sensor design that includes a securing device with a housing lock and a container lid with a downward angled edge and eyelet for secure attachment, preventing removal without visible tampering, and allowing for stackable container configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensor is mounted inside the container with tight sealing, then the sensor is protected from contamination and manipulation, but the sensor cannot be easily mounted or dismounted
Solution Approach 1:
The sensor system is divided into separable components: the sensor unit itself and the container lid assembly. The sensor can be mounted inside the container and the lid sealed separately, allowing the sensor to remain protected while enabling independent access for maintenance or replacement without compromising the sealed environment.
2Ease of operation
If the sensor is mounted outside the container, then the sensor is easily accessible for mounting and dismounting, but the container cannot be assembled in a space-saving manner
Solution Approach 1:
The sensor is positioned within the container opening or integrated into the lid structure, allowing it to be nested within the container's footprint. This enables space-saving container assembly while keeping the sensor accessible for mounting and dismounting through the container opening without requiring external mounting space.
3Reliability
If the container lid is sealed with closed withdrawal system, then manipulation is prevented and contamination avoided, but the sensor cannot be easily accessed for maintenance
Solution Approach 1:
The container lid is designed with a sealed closure system that maintains integrity during normal operation, preventing contamination and manipulation. The sensor is positioned such that it can be accessed through the container opening or integrated into the lid structure, allowing maintenance to be performed before the lid is fully sealed or through designated access points without breaking the seal.
4Ease of repair
If the sensor is made removable for maintenance, then the sensor can be easily accessed and replaced, but the sensor becomes vulnerable to manipulation and contamination
Solution Approach 1:
The sensor mounting design includes anti-manipulation features such as tamper-evident seals, locking mechanisms, or specialized fastening systems that prevent unauthorized removal or manipulation. These features are integrated into the mounting structure, allowing legitimate maintenance while preventing improper access or contamination during the maintenance process.

AI summary
A tamper-proof sensor is adapted to be mounted on or in an opening of a container and to detect a process variable in a container. The sensor has a securing device which is designed to detect or prevent the sensor from being removed from the opening of the container.
