Conductive Identification Strap With Adjustable Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identification straps for tracking objects or persons within a building often slip off or can be cut, leading to loss of identification security, particularly in applications like monitoring young children.
Innovation Solution
An adjustable identification device with an electrically conductive strap and wireless communications transceiver module, featuring a locking mechanism that forms a secure, adjustable circular lock and ensures electrical continuity, preventing accidental disengagement and enabling secure tracking and location within a building.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed-size identification strap is used, then the strap can be securely locked around the object or person, but it cannot be adjusted to fit different sizes or may slip off if too loose
Solution Approach 1:
The identification strap incorporates multiple orifices at its ends, allowing the locking projection to be positioned at different locations along the strap perimeter. This dynamic adjustment mechanism enables the strap to adapt to different wrist or ankle sizes while maintaining secure locking, resolving the contradiction between fixed security and size adaptability.
2Reliability
If the identification strap is made tight to prevent slipping off, then security is improved, but it may be uncomfortable or harmful to wear
Solution Approach 1:
The adjustable orifice mechanism allows the strap to be fitted with appropriate tension for different wearers and applications. This dynamic adjustment capability enables optimization between security (preventing removal) and comfort/safety (avoiding excessive tightness), resolving the contradiction between prevention of removal and wearer comfort.
3Ease of operation
If a simple locking mechanism is used, then ease of operation is improved, but the strap can be easily cut or tampered with
Solution Approach 1:
The locking projection acts as an intermediary mechanical element that provides tamper resistance through its engagement with the orifices. The projection's design with a head portion and shaft creates a mechanical locking action that is both simple to operate (can be inserted and locked) and resistant to tampering (requires specific manipulation to release). This resolves the contradiction between operational simplicity and tamper resistance.
4Manufacturing precision
If the identification strap is made non-adjustable, then manufacturing precision is improved, but it cannot accommodate different body parts or objects
Solution Approach 1:
The strap incorporates multiple discrete orifices at its ends, creating segmented adjustment positions. This segmentation allows the strap to be manufactured with consistent dimensions while providing discrete size options for different body parts or objects. The segmented design resolves the contradiction between manufacturing consistency and adaptability to different sizes.

AI summary
An identification device that can be adjustably fit around an object or person whose identity is to be monitored comprises an electrically conductive identification strap (12); electrically conductive locking means (21) designed for adjustable circular locking of the identification strap (12) around a predetermined part of the object or person whose location is to be monitored, thus forming a closed electrical circuit when the electrically conductive identification band (12) and the locking means are both in the working or closed position; and a wireless communications transceiver module (13) designed to establish communication with at least one transceiver module (13) mounted in a different identification device (11) fit onto a different object or person, wherein a first transceiver module (31) executes a linking procedure by radio transmission of identification data streams to at least one other transceiver module (31) in listening mode to receive the identification data stream transmitted from the first identification device (11).
