Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If fibers are separated from non-fiber content using prior art separation devices, then waste removal is improved, but fiber contamination and exposure to external influences worsen, making precise analysis difficult
Solution Approach 1:
The patent introduces a collection surface as an intermediary between the separation process and analysis. This surface captures fibers in a controlled manner, protecting them from external contamination while enabling precise quantitative and qualitative analysis. The collection surface acts as a mediator that preserves fiber integrity separate from the waste removal process.
Solution Approach 2:
The patent extracts fibers from the separation process and places them on a dedicated collection surface for analysis. This extraction isolates the fibers from the harmful environment of the separation device, allowing for contamination-free analysis while maintaining the waste removal function.
2Measurement precision
If fibers are pressed between collection surface and pressure surface, then fiber structure analysis is improved, but device complexity increases due to additional actuators and surfaces
Solution Approach 1:
The patent merges the collection surface and pressure surface into a coordinated pressing mechanism. By combining these surfaces with actuators that move them between positions, the device achieves both fiber containment for analysis and structured removal capability, balancing functionality with controlled complexity.
Solution Approach 2:
The patent employs dynamic actuators that move the collection and pressure surfaces between at least two positions: a first position for pressing fibers for analysis and a second position for releasing and removing fibers. This dynamic positioning allows the same structure to serve multiple functions, reducing overall device complexity.
3Measurement precision
If fibers are spaced apart on collection surface, then individual fiber identification is improved, but fiber collection efficiency may worsen
Solution Approach 1:
The patent applies local quality by creating spaced-apart fiber arrangement on the collection surface in the analysis region. This local spacing enables individual fiber identification and structure analysis while the overall collection process maintains efficiency through the coordinated action of feed and dissolving rollers that deliver fibers to the collection surface.
