Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting tampering of containers, such as limit switches, are unreliable due to mechanical wear and lack remote monitoring capabilities, necessitating a more robust and reliable solution.
Innovation Solution
A plug with attachment means, a motion sensor, and communication means that rotates to close a container opening, detects rotation using a motion sensor, and communicates with a server to compare the detected rotation against a service schedule, generating alerts for deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical means such as limit switches are used to detect tampering, then the detection function is provided, but the system suffers from mechanical wear and lack of remote monitoring capability
Solution Approach 1:
The patent replaces mechanical detection systems (limit switches) with electronic sensors (accelerometers, gyroscopes) that detect motion and orientation changes digitally. This eliminates mechanical wear while maintaining detection functionality, directly resolving the contradiction between reliability and mechanical wear.
Solution Approach 2:
The patent introduces communication modules as intermediaries between the sensors and remote monitoring systems. This enables remote monitoring capability without adding complexity to the core detection mechanism, allowing the system to overcome the limitation of lacking remote monitoring while keeping the device structure manageable.
2Adaptability or versatility
If remote monitoring capability is added to detect tampering, then monitoring capability is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions (motion sensing, orientation detection, communication) into a single plug device that attaches to containers. This multi-functional approach enables remote monitoring capability without proportionally increasing complexity, as all functions share common hardware platforms and processing resources.
Solution Approach 2:
The system automatically detects tampering events and communicates them to remote servers without requiring manual intervention. The self-service nature of the system reduces operational complexity while maintaining enhanced monitoring capabilities, as the device autonomously performs detection, processing, and communication tasks.
