Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a multi-layer shuttle stereoscopic warehouse or Miniload is used to implement temporary storage and sorting functions, then the storage capacity and sorting capability are improved, but the device complexity and investment cost increase significantly
Solution Approach 1:
The patent applies the nesting principle by placing the temporary storage passage inside the spiral structure formed by the conveying lines. The storage passage is nested within the spatial envelope created by the ascending and descending conveying paths, allowing storage functionality to be integrated within the transport structure itself rather than requiring separate storage modules.
Solution Approach 2:
The patent merges the storage function with the conveying function by integrating the temporary storage passage directly into the spiral conveying system. Articles are conveyed along the spiral path and can be temporarily stored at designated positions along this path, combining what would traditionally be separate storage and transport systems into a unified structure.
2Device complexity
If a matrix temporary storage system is used for moderate article transport volumes, then the device complexity is reduced, but the occupied area increases and sorting capability is limited
Solution Approach 1:
The patent transitions from a two-dimensional matrix layout to a three-dimensional spiral configuration. The conveying lines ascend and descend in a vertical spiral around the central storage passage, utilizing the vertical dimension to achieve compact space occupation while maintaining efficient article flow and sorting capability.
Solution Approach 2:
The patent employs a spiral (curved) configuration for the conveying lines instead of straight linear paths. The ascending and descending lines form a spiral structure around the central storage passage, allowing articles to be conveyed through curved paths that efficiently utilize vertical space and reduce the horizontal footprint of the system.
3Ease of manufacture
If traditional storage systems are used, then the implementation is simple, but the storage capacity per unit area is low
Solution Approach 1:
The system utilizes vertical space by implementing a three-dimensional spiral configuration where conveying lines ascend and descend around a central storage passage. This vertical utilization of space significantly increases storage capacity per unit area compared to traditional horizontal storage arrangements.
Solution Approach 2:
The temporary storage passage is nested within the spiral structure formed by the conveying lines, maximizing the use of available space. This nested configuration allows the storage function to be integrated within the transport structure, increasing storage density without proportionally increasing system complexity.
