RF Tracking System for Lost Items
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for locating lost items are inefficient, requiring human effort and often result in delays and errors, with many lost items going unnoticed due to lack of awareness or limited publicity.
Innovation Solution
A wireless pairing and tracking system that uses identifier devices with RF links, paired with observing devices and a host apparatus, allowing for automatic registration and tracking of lost items via Bluetooth connections, GPS, and database servers, enabling efficient location through participating observing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual searching methods are used by proximate people, relatives, friends or local authorities, then human effort can be directly applied to search for lost items, but the process becomes time-consuming, costly, and error-prone
Solution Approach 1:
The lost item itself performs the search function by broadcasting its identity via RF signals. Any observing device within range can automatically detect and report the item's location, eliminating the need for manual searching by humans. The system makes the searched object actively participate in its own location process.
Solution Approach 2:
RF observing devices act as intermediaries between the lost item and the search initiators. These devices automatically detect RF broadcasts from lost items and relay location information through a server, replacing manual human search efforts with automated electronic mediation.
2Loss of information
If lost items are within proximity of other persons but not detected, then the items may be physically near potential helpers, but lack of awareness prevents recovery
Solution Approach 1:
The system makes the invisible lost item visible by having it broadcast its identity through RF signals. Observing devices detect these broadcasts and display information about the lost item to potential helpers, effectively 'lighting up' or highlighting the presence of lost items that would otherwise go unnoticed.
Solution Approach 2:
The system establishes a feedback loop where lost items continuously broadcast their identity, observing devices monitor and detect these broadcasts, and information is relayed back to the item owner through a server. This continuous feedback ensures that lost items are detected and reported whenever they are within range of observing devices.
3Productivity
If automated tracking systems are implemented using RF links and observing devices, then the location of lost items can be efficiently determined, but the system complexity increases with multiple components including identifier devices, observing devices, and host apparatus
Solution Approach 1:
The system uses universal RF communication that can be implemented across multiple types of devices (identifier devices attached to various lost items, observing devices in smartphones or other electronics). This multi-functionality allows the same basic RF mechanism to track diverse items without requiring specialized complex systems for each item type.
Solution Approach 2:
The server acts as a central intermediary that manages the complexity of coordinating multiple identifier devices and observing devices. Rather than requiring direct complex interactions between all system components, the server mediates information flow, matching lost item broadcasts with observing devices and relaying information to owners, thereby simplifying the overall system architecture.
