Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a plane screen mesh is used, then the structure is simple, but the layering of materials is not obvious and screening effect is poor
Solution Approach 1:
The screen mesh surface is designed with wave-shaped protrusions instead of a flat plane. The curvature of the wave-shaped surface creates different climbing angles for materials, causing coarse materials to quickly cross crests while fine materials and moisture are retained in troughs, achieving obvious layering and improved screening efficiency by 8-15%
Solution Approach 2:
The invention transitions from a two-dimensional flat screen surface to a three-dimensional wave-shaped surface with varying heights. The wave-shaped protrusions create additional spatial dimensions (crests and troughs) that enhance material layering and improve the screening process
2Productivity
If vibration frequency and amplitude are increased to improve screening, then screening efficiency improves, but coarse and fine materials are wrapped and entrained affecting screening effect
Solution Approach 1:
The wave-shaped surface creates different climbing angles and paths for materials of different sizes. Coarse materials with greater climbing capacity quickly cross the wave crests, while fine materials are retained in the troughs, achieving effective separation without material wrapping or entrapment even at high vibration frequencies
3Weight of moving object
If polyurethane material is used instead of metal, then weight is reduced and self-cleaning effect is improved, but screening efficiency needs enhancement
Solution Approach 1:
The wave-shaped protrusions on the polyurethane screen mesh create dynamic crests and troughs during vibration. This curvature enhances the self-cleaning effect while promoting material layering, allowing fine materials and moisture to be effectively retained and screened, improving screening efficiency by 8-15% while maintaining the light weight advantage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves screening efficiency by promoting material layering, retaining fine materials and moisture, and increasing the penetrating screening rate by 8 to 15%, reducing secondary crushing workload and power loss.
Implementation Method 1
the high-frequency vibrating screen utilizes the excitation of a vibrating motor as a vibrating source, so that materials are thrown up, loosened and layered on a screen mesh
Implementation Method 2
promotes the layering of the materials by using the difference of the climbing capacity of the granular materials with different particle sizes; large granules quickly cross over a crest to continue running, and small granules and moisture retain in a trough

AI summary
The present disclosure discloses a wave-shaped polyurethane high-frequency linear vibrating screen mesh, which solves the problems of unobvious layering and poor screening effect of the existing screen mesh. The wave-shaped polyurethane high-frequency linear vibrating screen mesh comprises a side blind area and a screening area. The screen area is composed of wave-shaped injection molding polyurethane screen pieces. Materials roll forward along the direction of material flow in a wavy manner. Clamping grooves are formed in the blind area, which can be in buckle fit on rail seats of a small beam of a screening machine. The screen gap direction of the screening area is consistent with the direction of the material flow. Through the arrangement of a wave-shaped screen mesh surface, the wave-shaped polyurethane high-frequency linear vibrating screen mesh effectively optimizes the running state of the materials, and promotes effective layering of coarse and fine materials.
