Solution Overview
Problem
Existing pressing devices struggle to efficiently compress long-stemmed plant materials like Miscanthus and corn into bales with sufficient density for economic utilization, while also being mobile and capable of on-site processing.
Innovation Solution
A pressing device with a pressing chamber, a movable pressing element, and a binding apparatus that allows for the formation of partial bales, which are then connected to create a final bale with uniform size and high compression density, facilitating efficient transport and energy utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If higher pressing forces are applied to compress long-stemmed plant material, then compression density is improved, but device dimensioning and complexity increase
Solution Approach 1:
The pressing process is divided into multiple stages with different pressing elements having different cross-sectional areas. The first pressing element has a larger cross-section for initial compression, while the second pressing element has a smaller cross-section for final densification. This segmentation allows achieving high compression density without requiring a single oversized pressing device.
Solution Approach 2:
The pressing device uses two different pressing elements with different geometries in sequence. The first pressing element compresses the plant material broadly, while the second pressing element with smaller cross-section applies concentrated force for final densification. This dynamic approach to compression allows achieving high density without permanently increasing device dimensioning.
2Manufacturing precision
If a larger pressing device is used to achieve sufficient compression of long-stemmed plant material, then compression density is improved, but mobility is worsened
Solution Approach 1:
The pressing function is segmented into two stages using two different pressing elements. The first element handles bulk compression, while the second element provides final densification. This allows the device to maintain a compact, mobile structure while achieving high compression density through sequential processing.
Solution Approach 2:
The first pressing element performs the bulk of the compression work with a larger cross-section, while the second pressing element with smaller cross-section completes the densification process. This partial action approach allows the device to be dimensioned for mobility while still achieving sufficient compression density through the combined effect of both pressing elements.
3Quantity of substance
If the pressing space is enlarged to accommodate long-stemmed plant material, then compression capacity is improved, but device dimensioning and mobility are worsened
Solution Approach 1:
The compression capacity is segmented into two pressing stages. The first pressing element with larger cross-section handles the bulk material, while the second pressing element with smaller cross-section performs final densification. This allows the device to process large quantities of long-stemmed plant material without requiring a permanently enlarged pressing space.
Solution Approach 2:
Instead of enlarging the pressing space in all dimensions, the invention uses two pressing elements with different cross-sectional areas. The first element operates with a larger cross-section to accommodate long stems, while the second element uses a smaller cross-section for final compression. This dimensional approach allows high compression capacity without permanently increasing device dimensioning.
