Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional edge barrier elements are designed with sufficient strength and stability to meet safety standards, then they become heavy and cumbersome, but if they are made lighter for easier handling and transport, then their structural stability and strength are compromised
Solution Approach 1:
The edge barrier element is divided into multiple modular components including horizontal edges, vertical edges, and intermediate steel wires arranged in a grid pattern. This segmentation allows each component to be optimized independently for strength-to-weight ratio, enabling the overall structure to achieve required stability with reduced total weight compared to solid monolithic designs.
Solution Approach 2:
The edge barrier element combines steel wires of different diameters and configurations to create a composite wire rope structure. Thicker steel wires are used at critical locations (horizontal and vertical edges) for structural integrity, while thinner intermediate wires provide additional stability. This composite approach optimizes the weight-strength-stability balance by placing material only where structurally necessary.
2Strength
If edge barrier elements are designed with complex structures to enhance strength and stability, then they provide better safety performance, but they become more difficult and expensive to manufacture and assemble
Solution Approach 1:
The barrier element is constructed from standardized segmented components (horizontal edges, vertical edges, intermediate wires) that can be manufactured independently using conventional wire drawing and cutting processes. This segmentation simplifies manufacturing compared to producing complex monolithic structures, as each component can be made using basic wire rope fabrication techniques already common in the industry.
Solution Approach 2:
Multiple wire components are merged through welding to form the complete edge barrier element. The horizontal and vertical steel wires are welded at intersection points to create a unified grid structure. This merging approach achieves complex structural strength through simple welding operations rather than requiring complex forming or machining processes.
3Stability of the object's composition
If edge barrier elements are designed with sufficient structural stability to prevent distortion, then they maintain their shape under load, but they require more material and occupy more space during transport and storage
Solution Approach 1:
The edge barrier element uses a flexible wire rope grid structure instead of rigid solid panels. This thin-film-like wire mesh provides sufficient structural stability to maintain shape under operational loads while occupying minimal volume during transport. The flexible nature of the wire components allows the structure to be compacted or folded for efficient storage and transportation.
Solution Approach 2:
The segmented wire grid structure achieves shape stability through the distributed arrangement of vertical and horizontal wires rather than requiring solid continuous material. This segmentation allows the structure to maintain its geometric form under load while using minimal material volume, as the wires provide structural support only where needed rather than requiring full solid cross-sections.
4Strength
If third steel wires are added on the second side of the first steel wires to improve stability, then unexpected constructional strength is achieved, but the device complexity increases
Solution Approach 1:
The third steel wires are positioned asymmetrically on the second side of the first steel wires rather than creating a perfectly symmetric double-sided grid. This asymmetric arrangement provides the unexpected constructional strength benefit of having wires on both sides for enhanced stability, while avoiding the full complexity of a completely symmetric design. The asymmetry allows optimization of strength distribution based on actual load patterns.
Solution Approach 2:
The third steel wires are strategically positioned at specific locations on the second side rather than creating a uniform dense grid on both sides. This local quality approach provides enhanced constructional strength at critical locations where the third wires counterbalance the second wires, while minimizing overall structural complexity by not over-engineering areas that don't require additional reinforcement.

AI summary
The invention relates to an edge barrier element for use in building construction or the like. The edge barrier element (1) is rectangular and has a first and a second horizontal edge (2, 2'), which are parallel to each other, and a first and a second vertical edge (3, 3'), which are parallel with each other and perpendicular to the first and second horizontal edge (2, 2'). The barrier element (1) further comprises a plurality of first steel wires (4, 4', 4"), which are arranged to connect the first and the second horizontal edge (2, 2'), and which are parallel with the first and the second vertical edge (3, 3') and between them, as well as a plurality of second steel wires (5, 5', 5", 5"'), which are arranged on a first side of the first steel wires (4, 4', 4"), perpendicular to them and attached to them by welding. Furthermore, at least on the first and second horizontal edge (2, 2') third steel wires (6, 6') are arranged at a second side of the first steel wires (4, 4', 4"), so that the third steel wires (6, 6') are essentially opposite and parallel to corresponding second steel wires (5, 5', 5", 5"') on the first side of the first steel wires (4, 4', 4")..
