Solution Overview
Problem
Existing support legs for ballistic shields are cumbersome, difficult to use, and inadequate for maintaining the shield upright on uneven terrain, especially under the impact of high-speed objects, and they often make noise during transport.
Innovation Solution
A compact, lightweight support leg with a turnable and lockable frame portion and a telescopically extendible leg portion that can be easily converted between transport and supporting positions, using magnets for silent operation and stability on various terrains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a telescoping and retractable support leg is used to keep the ballistic shield upright, then the shield can be supported in a vertical position, but the support leg becomes difficult to use and makes noise during transport
Solution Approach 1:
The support leg employs a telescopic mechanism with multiple segments that can dynamically extend and retract. The leg transitions from a compact retracted state during transport to an extended stable state during use, allowing the system to adapt its configuration based on operational requirements. This dynamic transformation resolves the contradiction by providing stability when needed while maintaining compactness for easy transport.
Solution Approach 2:
The support leg is divided into multiple telescopic segments that can extend and retract independently. This segmentation allows the leg to achieve greater extended length for stability without proportionally increasing the retracted size, and enables smooth transition between states. The segmented structure also distributes mechanical stresses across multiple joints, improving reliability while maintaining ease of operation.
2Length of moving object
If the support leg is made compact for transport, then it is easier to carry, but it may not provide sufficient support on uneven terrain
Solution Approach 1:
The support leg utilizes a nested telescopic structure where multiple leg segments are housed within each other when retracted, achieving a compact form factor for easy transport. When deployed, the segments extend sequentially to provide the necessary length and stability for supporting the ballistic shield on uneven terrain. This nesting principle allows the leg to transition between compact and extended states without compromising either transport convenience or support reliability.
Solution Approach 2:
The telescopic support leg can dynamically adjust its extended length based on terrain conditions and load requirements. The leg extends to provide maximum stability on uneven ground, then retracts to a compact size for transport. This dynamic adaptability resolves the contradiction by allowing the leg to optimize its dimensions for each operational phase rather than being fixed at a single length.
3Reliability
If the support leg is extended to provide firm support, then the shield remains upright, but the leg portion increases in size and weight
Solution Approach 1:
The telescopic support leg employs a nested structure where multiple segments are housed within each other when retracted, achieving a compact form factor for easy transport. When deployed, the segments extend sequentially to provide the necessary length and stability for supporting the ballistic shield on uneven terrain. This nesting principle allows the leg to transition between compact and extended states without compromising either transport convenience or support reliability.
Solution Approach 2:
The support leg employs a telescopic mechanism with multiple segments that can dynamically extend and retract. The leg transitions from a compact retracted state during transport to an extended stable state during use, allowing the system to adapt its configuration based on operational requirements. This dynamic transformation resolves the contradiction by providing stability when needed while maintaining compactness for easy transport.
