Ballistic Backpack Apron Deployment via Magnetic Flap and Elastic Straps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backpacks with ballistic inserts are not discreet enough and do not deploy quickly enough to provide maximum protection for wearers, especially in law enforcement scenarios.
Innovation Solution
The design incorporates elastic apron straps for easier head passage, a magnetic fastener for quick flap deployment, and an apron belt for improved torso protection, along with a pull handle configuration that accelerates deployment and allows for quick adjustment to provide comprehensive protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the apron is housed inside the compartment with a closed flap, then the backpack maintains a discreet appearance, but the deployment time increases and protection is delayed
Solution Approach 1:
The apron is pre-positioned inside the compartment and the flap is pre-configured with a passage and handle accessibility. When deployment is initiated, the apron can be quickly extracted through the pre-established passage without requiring complex manipulation, thus maintaining discretion during normal wear while enabling rapid deployment when needed.
2Ease of operation
If the apron straps are made elastic, then the head can pass more easily through the compartment opening, but the apron may not remain securely positioned against the torso
Solution Approach 1:
The apron straps are designed with elasticity to dynamically adapt to different states: when the wearer needs to pass their head through, the elastic straps extend to accommodate the movement; once the head is through, the straps naturally retract to pull the apron up against the torso, providing secure positioning without requiring additional fastening actions.
3Stability of the object's composition
If the flap is fixed securely to the compartment, then the backpack structure is stable, but the deployment speed decreases due to complex fastener mechanisms
Solution Approach 1:
The flap system is segmented into a fixed portion (the passage structure) and a movable portion (the flap itself). The passage is pre-formed in the compartment structure to maintain stability, while the flap can be independently manipulated to open and allow quick access to the apron handle, enabling both structural integrity and rapid deployment.
4Ease of operation
If the pull handle extends far above the flap, then the handle is easily accessible for quick deployment, but the backpack height and profile increase
Solution Approach 1:
The pull handle is nested within the flap structure when not in use, extending only slightly above the folded flap to maintain a compact profile. When deployment is initiated, the handle becomes fully accessible as the flap opens, providing ease of operation without permanently increasing the backpack's height or profile during normal carry conditions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The backpack can be deployed in under 2 seconds, offering effective protection for the torso and head while maintaining a discreet appearance, even when worn with helmets, and allows for easy access to firearms.
Implementation Method 1
In the closed position, the flap is fixed to the compartment by at least one magnetic fastener
Implementation Method 2
the apron straps have elasticity. When deploying the apron, that is, when moving it from the stowed to the deployed position, the wearer can pull the apron away from the edge of the compartment opening to create a gap for the wearer's head

AI summary
The invention relates to a backpack comprising: a flap (6) that can be moved between - a closed position - first and second open positions in which it leaves the opening of the compartment uncovered after pivoting, from the closed position, toward the rear and the front of the compartment respectively, a ballistic protection bib (50) that can be moved, by passing through the compartment opening and over the top, from a stowed position in which it is housed inside at a deployed position in which it protects the torso, bib straps (74, 76) connecting the bib to the compartment, able to suspend the bib in the deployed position.
