Filter Plate With Variable Material Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter plates have high dead weight, making them difficult to lift and transport, and require massive frames for support due to their high load-bearing capacity.
Innovation Solution
The filter plate incorporates areas with different material filling densities, allowing for a three-dimensional geometrically structured design where high-strength areas have high material density and lower-strength areas have lower density, reducing overall weight and allowing for single-operation production.

Engineering Contradiction Analysis
1Strength
If the filter plate uses high-density material throughout to ensure strength and stability, then the strength and stability are improved, but the dead weight increases significantly making it difficult to lift and transport
Solution Approach 1:
The filter plate applies local quality by varying the material filling density across different regions. The plate frame and specific structural areas use high material filling density (0.6-0.8) to provide strength and stability, while the working surface uses lower material filling density (0.2-0.4) to reduce weight. This localized differentiation allows the plate to meet strength requirements only where necessary.
Solution Approach 2:
The filter plate employs composite material construction by combining regions of different material filling densities within the same plate. The plate frame and structural elements use high-density material composition while the working surface uses low-density material composition, creating a composite structure that optimizes both strength and weight characteristics.
2Ease of manufacture
If the filter plate uses uniform material distribution throughout, then the manufacturing process is simple, but the weight cannot be reduced and strength is not optimized for specific application areas
Solution Approach 1:
The invention applies parameter changes by varying the material filling density parameter across different regions of the filter plate. The material filling density is changed from a uniform value to a spatially varying parameter, with the plate frame having density 0.6-0.8 and the working surface having density 0.2-0.4. This parameter variation is achieved through controlled material injection during manufacturing.
Solution Approach 2:
The invention transitions from two-dimensional uniform material distribution to three-dimensional non-uniform material distribution. The material filling density varies in the vertical dimension within the plate thickness, creating a geometrically structured volume structure with different density levels throughout the three-dimensional space of the filter plate.
