Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire screens have a uniform diameter and linear rod edges, which limit their aesthetic and industrial applications by restricting visual effects and flow distribution, and do not adapt well to non-uniform surfaces or varying surface loading.
Innovation Solution
A wire screen design featuring rods with non-uniform, undulating outer edges and varying diameters, where wires are wound in a spiraling pattern around the rods to create a cylindrical shape with sinusoidal or other variable geometries, allowing for adjustable gaps and enhanced filtering or aesthetic effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional wire screens have uniform diameter and linear rod edges, then manufacturing is simple and structure is stable, but aesthetic effects and flow distribution are limited
Solution Approach 1:
The patent applies asymmetry by replacing uniform linear rod edges with undulating or profiled edges that vary along the length of the rod. This creates non-uniform gaps between wires, enabling enhanced aesthetic effects such as light refraction and shadow play, while also improving flow distribution by creating varied flow paths. The asymmetric edge profile directly addresses the limitation of conventional uniform structures.
Solution Approach 2:
The patent implements local quality by varying the rod edge profile at different locations along the rod length. Different sections of the rod can have different undulation patterns or profiles, allowing localized optimization of either aesthetic effects or flow distribution characteristics. This enables the screen to have different functional properties in different regions without requiring complete structural redesign.
2Adaptability or versatility
If wire screens have uniform structure, then manufacturing is easier, but they do not adapt well to non-uniform surfaces or varying surface loading
Solution Approach 1:
The patent applies dynamics by creating a non-static, adaptive structure through undulating rod edges that can conform to varying surface conditions. The profiled edges provide inherent flexibility in the screen's geometric configuration, enabling it to adapt to non-uniform surfaces and varying surface loading conditions while maintaining structural integrity. This dynamic geometric configuration allows the screen to respond to different operational conditions.
3Reliability
If rods have linear edges, then the structure is simple and stable, but filtering capabilities and flow distribution are limited
Solution Approach 1:
The patent applies curvature by replacing linear rod edges with undulating or wave-like profiles. This curved geometry creates varying gap sizes between adjacent wires, which enhances filtering capabilities by providing more diverse flow paths and improved flow distribution. The curved edge profile increases the effective surface area for filtration while maintaining structural stability through the continuous undulating form.

AI summary
A screen has a plurality of rods arranged longitudinally around a central axis. The rods have first and second edges (e.g., inner and outer edges). Each of the first edges defines a profile that varies in lateral distances from the central axis along a longitudinal length of the rod. For example, the first edges can have an undulating profile of crests and troughs. With the plurality of rods disposed around the central axis, the profile produces a varied surface on the screen when a plurality of wraps from one or more wires is disposed laterally around rods. These one or more wires attach to the first edges of the rods and form a plurality of gaps.
