Transfer System for Seismic Misalignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transfer systems face difficulties in transferring articles between seismically isolated and non-isolated structures when the conveyors become misaligned due to earthquakes.
Innovation Solution
A transfer system that includes a first conveyor in a seismically isolated building and a second conveyor in a seismically non-isolated building, both capable of adjusting their vertical and horizontal positions to align with each other, ensuring uninterrupted article transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conveyors are fixed between seismically isolated and non-isolated structures, then structural stability is improved, but alignment reliability deteriorates during earthquakes
Solution Approach 1:
The conveyor system incorporates adjustable positioning mechanisms that enable dynamic adaptation to relative displacements between seismically isolated and non-isolated structures. The conveyors can be repositioned in vertical and horizontal directions to maintain proper alignment after earthquake-induced misalignment, transforming the system from static to dynamically adaptable.
Solution Approach 2:
The system changes the positional parameters of the conveyors by providing adjustment mechanisms that modify vertical positions and horizontal positions. This allows the conveyors to adapt to varying alignment conditions after earthquakes, changing their spatial coordinates to maintain functional connection between buildings.
2Adaptability or versatility
If conveyors are made adjustable to cope with misalignment, then adaptability is improved, but device complexity increases
Solution Approach 1:
The conveyor system is divided into separate adjustable components, with independent vertical position adjustment mechanisms and horizontal position adjustment mechanisms. This segmentation allows each component to be adjusted independently, providing adaptability while keeping individual adjustment mechanisms relatively simple rather than requiring a completely complex integrated system.
