Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ballistic shields are difficult to maintain in an upright position for extended periods due to their weight, leading to user fatigue and increased vulnerability in dangerous situations.
Innovation Solution
A support system with retractable legs and a hydraulic or spring-loaded mechanism that allows the ballistic shield to be raised and lowered, providing stability and mobility, along with a bulletproof screen and resting platform for the rifle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a ballistic shield is held manually for extended periods, then the user can maintain mobility and readiness, but user fatigue increases and vulnerability increases
Solution Approach 1:
The support system transitions between extended and retracted states dynamically. The legs can be extended to provide full support duration and then retracted when the user needs to be mobile, allowing the system to adapt between static support and dynamic mobility based on operational needs.
Solution Approach 2:
The support system acts as an intermediary between the user and the ballistic shield. By providing mechanical support through legs and a base, it mediates the burden of holding the shield, reducing user fatigue while maintaining operational capability.
2Ease of operation
If retractable legs are added to provide support, then user fatigue is reduced, but device complexity increases
Solution Approach 1:
The support system is segmented into distinct functional components: mounting plates attached to the shield, retractable legs with internal sleeves, a base for stability, and optional accessories like bulletproof screens and resting platforms. This segmentation allows each component to perform its specific function while keeping the overall design manageable.
Solution Approach 2:
The legs feature an internal sleeve structure where one leg segment is nested within another, allowing the legs to retract and extend smoothly. This nesting mechanism reduces the space required when retracted while providing full support when extended, effectively managing complexity through compact design.
3Adaptability or versatility
If the shield is raised to a higher position, then visibility and operational effectiveness improve, but stability decreases
Solution Approach 1:
The leg mechanism provides dynamic height adjustment, allowing the shield to be raised to operational heights for better visibility and then lowered to stable positions for maintenance. The system adapts between these states based on operational requirements, maintaining both height variability and stability when needed.
Solution Approach 2:
A hydraulic system replaces manual mechanical lifting to raise and lower the legs. This substitution provides smoother, more controlled height adjustment with less physical effort from the user, enabling precise positioning while maintaining stability through the hydraulic mechanism's inherent control.

AI summary
The invention features a support system which can be attached to a ballistic shield. The system features at least one telescoping or retractable leg which is mounted to the shield to create a standalone shield. The shield is positioned between plates which receive pins that hold the shield in position in the system. The system features a resting platform which provides an area for resting a gun or rifle, for example. A bullet proof screen extends from the bottom area of the shield towards the base of the system and provides additional security to the user when the shield is in the system.
