Segmented Safety Device for Rapid Tool Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld pressurized self-defense devices are cumbersome and time-consuming to access during confrontations, as they require retrieval from pockets or purses.
Innovation Solution
A safety device with a storage member and retention device, where the second portion is moveable between configurations to attach and detach from the first portion, allowing for quick access to tools like mace and alert members, and can be securely attached to a user's waist.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handheld pressurized self-defense devices are stored in pockets or purses, then the device is readily portable, but the device requires time-consuming retrieval and removal during confrontations
Solution Approach 1:
The storage member is divided into a first portion and a second portion that can be separated. The second portion can be quickly detached from the first portion to provide immediate access to safety tools without requiring complete device removal, thus resolving the contradiction between portability and access speed.
Solution Approach 2:
The second portion is designed to be moveable between a first configuration (attached to first portion) and a second configuration (detached from first portion). This dynamic design allows the user to quickly transition from stored state to deployed state, eliminating retrieval time while maintaining portability when needed.
2Ease of operation
If the second portion is always attached to the first portion, then the device remains compact and portable, but the tool cannot be quickly accessed
Solution Approach 1:
The device is segmented into detachable portions with a retention device that provides simple attachment and detachment functionality. This segmentation allows quick tool access while keeping the attachment mechanism relatively simple, avoiding excessive complexity.
Solution Approach 2:
The retention device extracts the essential function of attachment/detachment from a complex mechanism, providing a simple means to separate the second portion from the first portion for quick tool access without requiring complex locking or release systems.

AI summary
Safety devices and methods of using a safety device are described. An example safety device includes a storage member and a retention device. The storage member has a first portion, a second portion, and defines a first chamber. The second portion is moveable between a first configuration and a second configuration. In the first configuration the second portion is releasably attached to the first portion such that the first portion and the second portion cooperatively define the chamber. In the second configuration the second portion is free of attachment to the first portion. The retention device is disposed within the chamber and has a retaining arm.
