Electronic Monitoring Bracelet Mechanical Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic monitoring bracelets require electromagnets for mechanical connection, which can be unreliable and prone to failure.
Innovation Solution
An electronic monitoring bracelet with a mechanical connection that uses a movable locking plate and a drive unit, such as an electrical motor and cam mechanism, to lock and unlock the bracelet without the need for electromagnets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electromagnets are used for mechanical connection, then the bracelet can be locked and unlocked, but the system becomes unreliable and prone to failure
Solution Approach 1:
The patent replaces the electromagnetic locking system with a purely mechanical locking mechanism. The drive unit uses a cam mechanism that converts rotational motion into linear motion to move the locking plate between locked and unlocked positions. This mechanical substitution eliminates the unreliability of electromagnets while maintaining the locking functionality through mechanical means alone.
Solution Approach 2:
The invention extracts and removes the electromagnet component from the mechanical connection system. By eliminating the electromagnetic actuator and replacing it with a mechanical drive unit, the patent removes the source of reliability problems while preserving the essential locking and unlocking functions through a simplified mechanical system.
2Reliability
If a secure mechanical connection is implemented, then the bracelet prevents unauthorized removal, but the device becomes more complex
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: a locking plate with recesses for pins, a drive unit with cam mechanism, and housing structures. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity. The locking plate's recesses provide discrete locking points, and the cam mechanism provides a simple rotational control element.
Solution Approach 2:
The locking plate is designed as a movable component that can dynamically transition between locked and unlocked positions. The cam mechanism provides dynamic control through rotational motion, converting it into linear motion of the locking plate. This dynamic design allows the system to maintain security when locked while enabling easy unlocking when needed, without requiring complex multi-step mechanisms.
