Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tracking technologies are inadequate for timely and efficient location and identification of objects, particularly in scenarios like luggage at airports or cargo items in supply chain logistics, due to limitations in tracking and communication systems.
Innovation Solution
A tracking device with a passive RFID system integrated into a non-metallic, non-interfering body, resembling a double stud, that communicates via radiofrequency signals and is embedded within the object, allowing for wireless tracking and identification without protruding parts, minimizing interference and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tracking device is attached to an object, then tracking capability is improved, but the device may protrude and be susceptible to environmental damage
Solution Approach 1:
The tracking arrangement is nested within a tracking arrangement chamber that is integrally formed within the body. The antenna is disposed adjacent to the body, with its inner surface contacting an outer surface of the body, effectively hiding the tracking components inside the body structure while maintaining tracking functionality.
Solution Approach 2:
The antenna is substantially planar and can be integrated with the body, allowing it to conform to the body's outer surface without protruding. This flat, flexible design enables the antenna to be embedded within the body structure while maintaining RF signal communication capability.
2Device complexity
If the antenna is integrated with the body, then device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The tracking arrangement chamber is integrally formed within the body as a single piece, eliminating the need for separate housing components. The antenna is substantially planar and can be directly integrated with the body during molding, reducing assembly steps and overall device complexity.
Solution Approach 2:
The body is made of a non-metallic material that is non-interfering with RF signals, changing the material parameter to enable both integration and functional performance. This material selection allows the antenna to be embedded within the body without signal interference while maintaining manufacturing feasibility.
3Reliability
If the body is made of non-metallic material, then RF communication is improved, but structural strength may be reduced
Solution Approach 1:
The body is made of a non-metallic material that is non-interfering with RF signals, changing the material parameter to enable both integration and functional performance. This material selection allows the antenna to be embedded within the body without signal interference while maintaining manufacturing feasibility.
Solution Approach 2:
The body can be made of composite materials that combine non-metallic properties for RF compatibility with reinforcing elements to maintain structural strength. The engagement members with shoulders and tracks provide mechanical strength while the overall structure remains non-metallic for RF signal compatibility.
