Protective Wall Lateral Connection Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective wall systems face challenges in maintaining connection reliability under lateral loading from vehicle impacts, particularly in securing traffic routes and preventing vehicles from leaving the roadway.
Innovation Solution
The protective wall system features pressure elements with complementary projections and recesses, designed as base plates with trapezoidal or other geometric shapes, and is constructed with a frame or full-surface volume using materials like steel, concrete, or elastomers, with horizontal struts to prevent vehicle damage and enhance stability, and a tensile connection system for secure alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If protective wall elements are connected using conventional end-face connections, then assembly is simplified, but connection reliability under lateral loading from vehicle impacts deteriorates
Solution Approach 1:
The invention transitions from conventional end-face connections to lateral connections between adjacent protective wall elements. By connecting elements sideways rather than end-to-end, the system achieves superior resistance to lateral vehicle impacts while preserving assembly simplicity through standardized connection interfaces designed for this orientation.
Solution Approach 2:
The connection system employs asymmetric geometry with protruding connection elements on one wall element and corresponding recesses on the adjacent element. This asymmetric design creates form-fitting connections that specifically resist lateral forces from vehicle impacts while maintaining straightforward assembly procedures.
2Stability of the object's composition
If pressure elements are positioned close to the connection point, then connection stability improves, but the risk of vehicle damage during assembly increases
Solution Approach 1:
The invention introduces horizontal struts as intermediary elements that span between adjacent protective wall elements. These struts provide structural reinforcement and distribute lateral loads across multiple connection points, enhancing connection stability while creating a protective barrier that prevents direct vehicle contact with the connection region during assembly.
Solution Approach 2:
The solution positions pressure elements laterally offset from the direct connection line rather than immediately adjacent to it. This lateral displacement maintains connection stability through the reinforced structure while reducing the hazard to vehicles during the assembly process.
3Strength
If protective wall elements are made heavier for improved impact resistance, then protection effectiveness increases, but transportation and installation difficulty increases
Solution Approach 1:
The protective wall system is divided into discrete, modular elements that can be manufactured, transported, and installed separately. Each element is sized and weighted to balance impact resistance with handling feasibility, and the modular nature allows flexible configuration to achieve overall system strength without requiring excessively heavy individual components.
Solution Approach 2:
The protective wall elements utilize composite construction combining high-strength materials with optimized geometry. This approach achieves superior impact resistance through material properties and structural design rather than simply increasing mass, thereby maintaining ease of transportation and installation while enhancing protection effectiveness.

AI summary
The protection wall (1) has a pair of protective wall elements (2) which are detachably connected with each other. One or more of the land end side faces are formed at the front side of the wall elements and are connected between the wall elements in form-fitting manner. The end side faces of wall elements are connected to pressure elements such as plates which are contacted with each other. A barrier is formed between pressure elements and wall elements. A filling material made of concrete, plastic, elastomer, wood or composite of specified materials is provided.
