Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing powder distribution systems, such as those using rails, brushes, and nozzles, struggle with bulkiness, adaptability to different materials, and fail to achieve satisfactory volumetric and granulometric homogeneity, leading to defects in the final product, especially when dealing with sticky or powdery materials.
Innovation Solution
A device comprising a tank with a storage cavity and oscillating movement about an axis, featuring a first opening for material entry and a longitudinal slot for exit, allowing for the distribution of materials over a length greater than the supply orifice, ensuring homogeneous particle size and volume distribution through oscillation and temporary storage within the cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If nozzle systems are used for material distribution, then the distribution length can be extended, but the nozzles clog easily when the powder is sticky
Solution Approach 1:
The distribution element is made oscillating rather than stationary, creating dynamic motion that prevents material from adhering and clogging the distribution slots. The oscillation generates centrifugal forces that continuously clear the distribution surface, maintaining reliability while achieving extended distribution length.
Solution Approach 2:
The system applies mechanical oscillation to the distribution element at specific frequencies and amplitudes. This vibration prevents sticky powder from adhering to the distribution slots, eliminating clogging issues while maintaining the extended distribution length capability.
2Reliability
If rail and brush systems are used for material distribution, then sticky materials can be handled without clogging, but the systems become bulky and difficult to adapt to different materials
Solution Approach 1:
The invention extracts and eliminates the bulky rail and brush components from the distribution system. By using a simplified oscillating distribution element with slots, it achieves clogging resistance through motion rather than through complex mechanical contact components, thereby reducing device complexity and bulkiness.
Solution Approach 2:
The oscillating distribution element serves multiple functions: it distributes material linearly over extended lengths, prevents clogging through oscillation, and can be easily adapted to different materials by adjusting oscillation parameters. This multi-functionality replaces the need for material-specific rail and brush configurations.
3Device complexity
If conventional distribution systems are used, then the structure is simple, but they fail to achieve satisfactory volumetric and granulometric homogeneity
Solution Approach 1:
The oscillating motion of the distribution element creates dynamic material flow that enhances volumetric and granulometric homogeneity. The continuous movement prevents material bridging and ensures uniform distribution across the extended length, achieving high manufacturing precision while maintaining relatively simple structural complexity.
