Tamper-Proof Wearable Device With Ink Ejection Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracking devices are bulky, inconvenient, prone to misplacement, and can be easily tampered with or deactivated, making it difficult to identify victims and culprits in cases of human trafficking and preventing effective tracking.
Innovation Solution
A tamper-proof wearable device with a locking mechanism and ejection module that prevents unauthorized disassembly and ejects permanent ink when tampered, combined with a tracking module for remote location monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tracking devices are made detachable for ease of wearing, then comfort and convenience are improved, but the device can be easily removed or tampered with by unauthorized users
Solution Approach 1:
The locking mechanism is configured to prevent the first member from disengaging with the second member when in the locked state, proactively preventing unauthorized removal before it can occur. This preliminary protective action resolves the contradiction by maintaining detachability for legitimate use while blocking tampering attempts.
Solution Approach 2:
The ejection module is pre-configured to eject liquid ink through the opening when the locking mechanism detects tampering attempts. This preliminary preparation of defensive action ensures that tamper evidence is immediately available, resolving the contradiction between ease of operation and reliability.
2Reliability
If tracking devices are made permanent or securely attached, then tamper-proof capability is improved, but the device becomes bulky and inconvenient to wear
Solution Approach 1:
The wearable device is divided into separable first and second members that can be detachably engaged. This segmentation allows the device to provide tamper-proof capability when engaged while maintaining convenience through optional separation, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The locking mechanism provides dynamic control over the engagement state, switching between locked and unlocked states based on authorization. This dynamic capability allows the device to adapt between secure attachment and easy removal, resolving the contradiction between tamper-proof capability and wearing convenience.
3Device complexity
If tracking devices lack visible identification features, then device simplicity is maintained, but the ability to identify victims and culprits in human trafficking cases is reduced
Solution Approach 1:
The ejection module ejects liquid ink that leaves visible color marks on surfaces or skin. This color change provides clear visual identification of tampering events and location information, resolving the contradiction between device simplicity and identification capability by using a passive visual indicator rather than complex active displays.

AI summary
A device configured to be worn by a user is described. The device comprises a first member having an opening and a second member configured to be detachably engaged with the first member. The device further comprises a chamber comprising liquid ink, the liquid ink being in fluid communication with the opening via a passage extending between the chamber and the opening. The device further comprises a locking mechanism configured to switch between a locked state and an unlocked state, and an ejection module configured to eject the liquid ink through the opening of the first member when the locking mechanism is at the locked state thereof.
