Wearable Safety Device with Severable Cord and One-Way Mirror
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Victims of violent incidents often have their phones destroyed or confiscated, leaving them unable to contact authorities or family members for help, and are also disoriented during emergencies, making it difficult to escape or get found by police.
Innovation Solution
A wearable safety device with a main body, wearable cord, circuit board, camera, button, and electrocution unit that can notify authorities and record evidence, even if the cord is detached or severed, using GPS and a one-way mirror cover screen to discreetly capture incidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a phone is used to contact authorities, then communication capability is improved, but the phone can be destroyed or confiscated by attackers
Solution Approach 1:
The safety device extracts the essential emergency communication function from the phone, creating a separate wearable device that can alert authorities independently. The circuit board with alert functionality is separated from the main phone body, allowing it to operate even when the phone is destroyed or confiscated.
Solution Approach 2:
The wearable safety device acts as an intermediary between the victim and authorities. Instead of relying directly on the phone which can be compromised, the intermediary device provides a backup communication channel that is harder for attackers to destroy.
2Reliability
If the wearable cord is attached to the body, then the device remains wearable and functional, but attackers can detect and target it
Solution Approach 1:
The cover screen can change its optical properties to blend with the surrounding environment or appear as a normal decorative element. When viewed from the outside, it reflects light similarly to the case, making the device less conspicuous and harder for attackers to identify as a safety device.
Solution Approach 2:
The device is designed to be disposable or easily replaceable. The circuit board and components are arranged to allow quick replacement of the main body if compromised, while the wearable cord and basic alert functionality can be retained or quickly reconfigured.
3Loss of information
If the cover screen is transparent to allow camera viewing, then evidence recording capability is improved, but privacy and discretion are reduced
Solution Approach 1:
The cover screen utilizes optical properties to appear opaque or reflective from the outside while allowing the camera to capture images from the inside. The screen material is selected to have different optical transmission characteristics for incoming light versus outgoing light, enabling discreet operation.
Solution Approach 2:
Instead of using a mechanical transparent window that would compromise privacy, the patent replaces it with an optical system using the cover screen's light reflection and transmission properties. This substitution allows the camera to function while maintaining the appearance of a solid, private surface.
4Reliability
If multiple functions are added to the device, then safety capability is improved, but device complexity increases
Solution Approach 1:
The wearable cord serves multiple functions: it suspends the device, provides a physical attachment to the body, and acts as a trigger mechanism when severed. The cover screen serves both as a protective cover and an optical element for the camera. The button serves as both a manual alert trigger and a capacitor discharge trigger.
Solution Approach 2:
The patent merges the alert mechanism with the existing wearable cord attachment system. The circuit board utilizes the same physical connection points as the cord attachment, so no separate mounting structure is needed. The camera is integrated into the existing case structure rather than requiring a separate housing.

AI summary
A wearable safety device, including a main body, a wearable cord disposed on at least a portion of the main body to suspend the main body while being worn, and a circuit board disposed within at least a portion of an interior of the main body and connected to the wearable cord to notify at least one of police and at least one authorized person in response to at least one of the wearable cord detaching from the circuit board and the wearable cord being severed.
