Wireless Tape Nodes for Automated Interaction Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RFID-based access control systems in environments like oil refineries and hospitals are inefficient due to the need for individual interaction with readers, and there is a lack of real-time tracking of interactions to manage access and prevent disease spread.
Innovation Solution
A wireless tracking system using adhesive tape nodes with embedded sensors and communication capabilities to track interactions between users, assets, and ingress/egress points, storing and analyzing data to manage access and detect events like contamination or machinery failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional RFID readers are used for access control, then access permissions can be controlled, but the system requires individual interaction which reduces efficiency and increases time consumption
Solution Approach 1:
The wireless tape nodes automatically detect and track interactions between users and access points without requiring manual activation. The system self-records proximity events, interaction durations, and participant identifiers autonomously, eliminating the need for users to individually interact with readers while maintaining accurate access control logging.
2Reliability
If wireless tape nodes continuously monitor and track all interactions, then real-time tracking capability is achieved, but energy consumption increases
Solution Approach 1:
The wireless tape nodes employ periodic monitoring with configurable intervals rather than continuous tracking. The system activates sensors and wireless communication only at scheduled intervals or when triggered by motion detection, allowing the device to enter low-power states between monitoring cycles while still maintaining reliable interaction tracking capability.
Solution Approach 2:
The monitoring intensity and frequency of the tape nodes dynamically adjust based on environmental context, interaction history, and priority levels. High-priority interactions trigger immediate full-power monitoring, while routine periods utilize reduced monitoring frequency, optimizing the balance between tracking reliability and energy consumption.
3Loss of information
If detailed interaction data is collected and stored for all users and assets, then comprehensive tracking information is available, but data management complexity increases
Solution Approach 1:
The data management system is segmented into distributed components: tape nodes store local interaction logs, intermediate servers aggregate and filter data, and central databases maintain comprehensive records. This hierarchical segmentation allows detailed interaction data to be preserved while distributing storage and processing loads, reducing the complexity burden on any single system component.

AI summary
A wireless tracking system comprises a plurality of tape nodes associated with entities in an environment. The entities may comprise, for example, users, machinery, ingress and egress points of the environment. The tape nodes are configured to detect interactions that occur within the environment. Interactions may be defined based on one or more conditions, such as threshold durations or proximities between tape nodes. Interactions are stored by the tape nodes, uploaded to the wireless tracking system, and may be retrieved at a later time responsive to an event occurring, such as suspected contamination or incorrect use of machinery.
