Heavy-Duty Barrier Hook Connection for Uneven Ground Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heavy-duty barriers are often misused due to user perception of their ability to withstand forces beyond personal impact, leading to accidental overturning and safety risks.
Innovation Solution
A movable heavy-duty barrier design with a base part and a fence part featuring a rigid connection element that allows for interconnection with neighboring barriers through a movable attachment portion and hook portion, enhancing stability and enabling alignment at various angles and uneven ground accommodation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heavy-duty barriers are interconnected using chains attached to base parts, then the barriers can be connected to block areas, but the interconnection strength is insufficient and barriers can still be overturned by forces beyond personal impact
Solution Approach 1:
The connection element incorporates movable attachment portions that allow rotation and adjustment, transforming the rigid chain connection into a dynamic system that adapts to different barrier orientations and ground conditions while maintaining strong interconnection
Solution Approach 2:
The connection element combines rigid structural components with flexible attachment mechanisms, creating a composite connection system that provides both strength and adaptability, overcoming the limitations of simple chain connections
2Reliability
If the barrier is designed to be heavy and stable for personal safety, then it can prevent persons from entering worksites, but users mistakenly believe it can withstand larger forces leading to wrong usage and accident risks
Solution Approach 1:
The barrier design proactively addresses potential misuse by incorporating connection elements and structural features that prevent the barrier from being used beyond its intended capacity, thereby preemptively reducing accident risks from wrong usage
Solution Approach 2:
The movable attachment portions provide tactile and visual feedback to users about the barrier's connection status and load-bearing capacity, helping users understand the barrier's actual limitations and prevent misuse
3Strength
If the connection element is made rigid to increase interconnection strength, then barriers can withstand larger forces, but the ability to accommodate uneven ground and different angles is reduced
Solution Approach 1:
The connection element uses movable attachment portions with rotation capabilities that allow the rigid structure to adapt dynamically to uneven ground and different barrier angles, maintaining both strength and versatility
Solution Approach 2:
The connection element allows changes in orientation and position parameters through its movable components, enabling the rigid structure to accommodate various ground conditions and barrier arrangements while maintaining interconnection strength

AI summary
A heavy-duty barrier, which is movable, comprising a base part, which comprises a ballast, and a fence part attached to the base part. The fence part comprises a fixed bar structure and a rigid connection element, which is movably attached to the bar structure, and which is connectable with a complementary connection element of a neighbouring heavy-duty barrier. The connection element comprises an attachment portion movably attached to a bar portion of the bar structure, and a hook portion arranged to be engaged with a corresponding hook portion of the complementary connection element.
