Heavy-Duty Barrier Hook Connection for Higher Overturn Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heavy-duty barriers are often misused due to user perception of their ability to withstand forces beyond a person falling against them, leading to a risk of accidents when subjected to larger forces.
Innovation Solution
A heavy-duty barrier with a movable attachment mechanism, comprising a rigid connection element with a hook portion and attachment portion that allows interconnection with neighboring barriers, enhancing stability and requiring more force to overturn.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heavy-duty barriers are interconnected using chains, then the barriers can be connected to block areas, but the interconnection strength is insufficient to withstand large forces such as vehicle impacts
Solution Approach 1:
The connection element incorporates movable attachment portions that allow rotation and limited movement, transitioning from a static chain connection to a dynamic rigid connection. This enables the barriers to be firmly interconnected while maintaining ease of assembly and disassembly, resolving the contradiction between connection strength and device complexity.
2Reliability
If the barrier is designed to be very heavy and stable, then it can withstand forces from persons falling against it, but users mistakenly believe it can withstand much larger forces such as vehicle impacts
Solution Approach 1:
The rigid interconnection mechanism provides visible and tangible feedback about the true strength capabilities of the barrier system. The robust connection elements and their secure engagement visibly demonstrate the actual load-bearing capacity, correcting user misconceptions about what forces the barrier can safely withstand.
3Stability of the object's composition
If multiple barriers are interconnected to enhance stability, then the ability to withstand pushing forces improves, but the complexity of the connection system increases
Solution Approach 1:
The connection element merges multiple functions into a single component: it provides rigid structural connection, allows for easy attachment and detachment, accommodates ground unevenness through movement, and enables angular adjustment. This consolidation achieves enhanced barrier stability without proportionally increasing system complexity.

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 neighboring 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.
