Modular Collapsible Ballistic Shield for Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ballistic shields are cumbersome to transport and use, limiting their versatility and effectiveness, especially in situations requiring long-distance movement or simultaneous firearm use, due to their rigid design and size constraints.
Innovation Solution
A collapsible and modular ballistic shield system composed of releasably coupled armored sections, allowing for configuration into various shapes and sizes, with innovative mounts enabling hands-free use and easy transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional rigid ballistic shield is used, then protection effectiveness is improved, but portability and ease of transport deteriorate
Solution Approach 1:
The ballistic shield is divided into multiple modular armored sections that can be separated and reconfigured. Each section maintains protective capabilities while the modular design enables collapsed storage and easier transport, directly resolving the contradiction between protection effectiveness and portability.
Solution Approach 2:
The shield transitions from a static rigid structure to a dynamic reconfigurable system. The armored sections can be moved between locked (extended) and unlocked (collapsed) states, allowing the shield to adapt its form factor for different operational needs while maintaining protective function.
2Area of stationary object
If a large shield is used for clearing spacious areas, then protection coverage is improved, but adaptability to confined spaces deteriorates
Solution Approach 1:
The shield's segmented modular design allows it to be configured in different sizes and shapes by assembling or disassembling armored sections. This enables the same system to provide extensive coverage in spacious areas while being collapsible enough to fit in confined spaces like airplanes, directly addressing the adaptability contradiction.
Solution Approach 2:
The modular shield system serves multiple functions across different operational scenarios. The same armored sections can be assembled into large configurations for area clearing or collapsed into compact forms for transport in confined spaces, making the system universally applicable rather than scenario-specific.
3Reliability
If a heavy shield is used for maximum protection, then ballistic rating is improved, but physical strain on user deteriorates
Solution Approach 1:
By dividing the heavy shield into multiple modular armored sections, the weight is distributed across separate components. Users can carry and deploy only the necessary sections for each mission, reducing physical strain while maintaining the ballistic protection needed for the specific threat level.
Solution Approach 2:
The modular design allows users to employ partial configurations of the shield system based on the actual threat level. Instead of always deploying the full heavy shield, users can use only the necessary protective sections, reducing physical strain while maintaining adequate protection through selective deployment.

AI summary
A collapsible ballistic shield which provides a degree of protection against ballistic threats. The shield includes a head plate, an upper torso plate, a lower torso plate, an upper lock-and-release hinge joint, a lower lock-and-release hinge joint, a primary handle, and a strap-mounting fastener. The head plate is positioned opposite to the lower torso plate, across the upper torso plate to outline a shape of a body. The head plate is pivotably attached to the upper torso plate by the upper lock-and-release hinge joint. The lower torso plate is pivotably attached to the upper torso plate by the lower lock-and-release hinge joint. Resultantly, the shield may be collapsed, expanded, and broken down. The primary handle provides a grasping point and is mounted to a rear surface of the upper torso plate. The strap-mounting fastener allows the user to attach the shield to external structures.
