Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wood-based material separation machines are cumbersome and lack precision and efficiency in selecting various types of materials, particularly due to the distance of compressed air delivery nozzles from the blowing means.
Innovation Solution
A compact separation machine with nozzles positioned proximal to a blowing device, aligned collectors, and a collection zone between the separation element and blowing device, utilizing compressed air with higher pressure to selectively push materials into specific collection zones based on detection by an optical and inductive system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If compressed air nozzles are positioned at a distance from the blowing means, then the machine structure is simpler, but the machine becomes cumbersome and selection precision deteriorates
Solution Approach 1:
The patent merges the compressed air nozzles with the blowing device by positioning the nozzles in proximity to the blowing means, specifically downstream of the conveyor belt outlet end and upstream of the separation element. This integration allows the nozzles to work in conjunction with the blowing device to achieve precise material selection without requiring a cumbersome distant structure.
Solution Approach 2:
The patent introduces an intermediary collection zone positioned between the nozzles and the blowing device. This collection zone serves as a mediator that receives materials pushed by the nozzles and allows the blowing device to then push wood-based materials beyond the separation element, enabling precise selection through a coordinated multi-stage process.
2Volume of moving object
If compressed air nozzles are positioned at a distance from the blowing means, then the machine is more spacious, but the machine size becomes relevant and efficiency deteriorates
Solution Approach 1:
The patent combines the nozzles and blowing device into a compact integrated unit with the nozzles positioned in proximity to the blowing means. This merging eliminates the need for a large spaced-out structure while maintaining high selection efficiency through coordinated operation of the nozzles and blowing device.
Solution Approach 2:
The patent utilizes the vertical dimension by positioning the nozzles upstream and the blowing device downstream in the material flow path, with the collection zone arranged in between. This spatial arrangement in multiple dimensions allows compact packaging of the system while maintaining efficient material selection performance.
3Device complexity
If compressed air nozzles are positioned far from the blowing means, then the machine is less complex, but the efficiency of material selection deteriorates
Solution Approach 1:
The patent merges the nozzles and blowing device into a closely integrated system where the nozzles are positioned in proximity to the blowing means. This integration maintains relatively simple device structure while dramatically improving selection efficiency through the coordinated action of nozzles pushing materials into the collection zone and the blowing device propelling wood-based materials beyond the separation element.
