Stackable Barrier With Tapered Pins And Rib Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barrier units are inflexible and time-consuming to deploy or reconfigure in dynamic environments like airfields, requiring improved stacking and linking features for stability and rapid redeployment.
Innovation Solution
A stackable barrier unit design featuring elongate main bodies with diverging sidewalls, tapered engagement pins and bores for alignment, and rib-and-channel systems for nesting and registration, allowing for stable linking and efficient stacking and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional barrier units are used, then structural strength is maintained, but deployment speed and reconfiguration flexibility are reduced
Solution Approach 1:
The barrier assembly is divided into multiple discrete barrier units that can be independently handled, stacked, and deployed. Each unit contains integrated engagement features that enable rapid connection without complex assembly procedures, allowing quick deployment while maintaining structural integrity.
Solution Approach 2:
Barrier units are designed with nested stacking capability where units can be stacked vertically within each other when not in use. The engagement features allow units to nest securely, reducing storage space and enabling rapid deployment by simply unstacking and positioning units along the desired barrier line.
2Reliability
If barrier units are made stable and resistant to displacement, then impact resistance is improved, but ease of reconfiguration and redeployment is reduced
Solution Approach 1:
The barrier system transitions from static permanent structures to dynamic reconfigurable units. The engagement features provide stable connection during impact while allowing rapid reconfiguration by disengaging and repositioning units. This dynamic capability enables the same barrier units to serve different purposes in different configurations.
Solution Approach 2:
The barrier units can change their configuration parameters (position, orientation, arrangement) while maintaining their structural properties. The engagement features allow units to be repositioned to different locations and reconfigured into different barrier patterns, adapting to changing operational requirements while maintaining impact resistance through proper unit design.
3Stability of the object's composition
If permanent ground based structures are used, then stability is maintained, but deployment time and resource efficiency are reduced
Solution Approach 1:
Barrier units are pre-manufactured with integrated engagement features and can be pre-positioned or pre-stacked at strategic locations. This preliminary preparation eliminates the need for on-site construction or complex assembly during deployment, allowing rapid deployment while maintaining structural stability through the pre-engineered engagement features.

AI summary
A stackable barrier unit includes: an elongate main body having a top surface, a bottom surface, longitudinal ends, and two sidewalls each having an upper margin joined to the top surface a lower margin extending tower than the bottom surface of the main body. A base width defined between lower outer margins of the sidewalls is greater than a top width of the top surface. Engagement extensions having engagement features extend from the longitudinal ends for linking two or more barrier units together. The engagement features may include a tapered pin and a hole. A rib may connect the first sidewall to the second sidewall below the bottom surface. A channel may be formed in the top surface of the main body directly above and parallel to the at least one rib.
