SCBA Mounting Bracket With Automatic Locking and Remote Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing SCBA holders in vehicles require manual intervention for securing self-contained breathing apparatus (SCBA) during scenarios like collisions, and lack adjustability for different sizes and mounting locations, making them inefficient and inconvenient.
Innovation Solution
An automatic locking mounting bracket assembly with a clamping arrangement, guide, and support structure that automatically secures and releases the SCBA using a spring-loaded mechanism, allowing vertical adjustment and release from various locations, including a powered latching mechanism for secure storage during vehicle travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual intervention is used to secure SCBA in holders, then the SCBA can be restrained during collisions and abrupt maneuvers, but the securing process is time-consuming and requires user action
Solution Approach 1:
The mounting bracket assembly employs a spring-loaded automatic locking mechanism that self-activates when the SCBA is inserted. The spring-loaded actuator detects the presence of the SCBA and automatically engages the locking mechanism, eliminating the need for manual intervention while ensuring reliable restraint security.
2Device complexity
If fixed mounting brackets are used for SCBA, then the structure is simple, but the brackets cannot accommodate different sizes and types of SCBAs
Solution Approach 1:
The mounting bracket incorporates adjustable components including a vertically movable clamping arrangement and an adjustable guide positionable at different locations along the mounting plate. These dynamic elements allow the bracket to adapt to various SCBA sizes and configurations while maintaining a relatively simple overall structure.
3Ease of operation
If automatic locking mechanism is implemented, then SCBA can be quickly secured without manual intervention, but the mechanism complexity increases
Solution Approach 1:
The automatic locking mechanism utilizes the SCBA itself as the actuating force. When the SCBA is inserted into the mounting bracket, its presence automatically triggers the spring-loaded locking mechanism through direct mechanical interaction, eliminating the need for separate actuators or complex control systems.
4Reliability
If SCBA is always restrained in mounting bracket, then safety during vehicle travel is ensured, but quick release for use is delayed
Solution Approach 1:
The mounting bracket includes a remotely operable release mechanism that can be actuated from a location away from the SCBA storage position. This allows the locking mechanism to be disengaged quickly by pulling a cable or actuating a switch located in an accessible position, enabling rapid SCBA retrieval while maintaining secure restraint during normal operation.

AI summary
A mounting bracket assembly includes a clamping arrangement mounted for vertical movement on a mounting structure and is movable between an engaged position and disengaged position relative to a self-contained breathing apparatus held in the mounting bracket assembly. A camming arrangement is located between the clamping arrangement and the mounting structure for permitting and preventing vertical movement of the clamping arrangement relative to the mounting structure. A powered latching mechanism is engageable with a portion of the clamping arrangement for providing unlatched and latched positions. A control arrangement separate from the powered latching mechanism is operatively connected thereto to selectively control the powered latching mechanism and effect release of the self-contained breathing apparatus from the latched position when the vehicle is in a stationary and parked condition.
