Nested Film Bag Arrangement for Silicon Fragment Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport containers for silicon fragments face issues with contamination and comminution due to excessive freedom of movement during transport, leading to inefficient packing and increased logistics steps, which affects the quality and quantity of silicon transported.
Innovation Solution
A transport container design using at least three film bags or double film bags with optimized packing densities, where the bags are arranged to minimize movement and maximize space utilization, allowing for a higher payload capacity without increasing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the bags are arranged with partial overlap to achieve a packing density of 650-950 kg/m³, then the packing density is improved, but voids are produced and space utilization in freight containers is suboptimal
Solution Approach 1:
The patent changes the arrangement parameter from partial overlap to nested arrangement (one bag inside another), and adjusts the packing density to a higher range of 950-1100 kg/m³. This parameter change eliminates voids while maintaining high density and optimal space utilization in freight containers.
2Productivity
If the packing density is increased to maximize transport economy, then the payload utilization is improved, but the risk of punctures and contamination increases
Solution Approach 1:
The patent applies nesting by placing one film bag inside another film bag, creating a protective nested structure. This allows achieving high packing density of 950-1100 kg/m³ for transport economy while the nested configuration reduces puncture risk and contamination, thereby maintaining reliability.
3Adaptability or versatility
If the bags have excessive freedom of movement during transport, then the packing flexibility is improved, but punctures and further comminution occur
Solution Approach 1:
By nesting one bag inside another, the patent restricts the freedom of movement of the inner bag while maintaining overall packing flexibility. The nested structure provides mechanical support that prevents punctures and further comminution during transport, thus improving reliability.
4Reliability
If additional operations are performed to remove fine fraction from further comminution, then the silicon quality is improved, but the number of logistics steps increases
Solution Approach 1:
The patent performs preliminary action by using the nested bag arrangement to prevent further comminution during transport. This preliminary protective measure reduces the formation of fine fraction, thereby reducing or eliminating the need for subsequent removal operations and reducing logistics steps.
