Multi-Layer Side Track Buffer for Higher Container Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage systems in semiconductor manufacturing plants are inefficient due to limited storage capacity, as they typically allow only a single layer of containers, restricting the number of substrates that can be stored efficiently.
Innovation Solution
A side track buffer apparatus with multiple layers of plates and a driving unit that reciprocates upper plates laterally, allowing for the storage of multiple containers, facilitated by a transmission shaft or tension spring for movement and control, and sensors for detection and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single layer storage system is used, then the structure is simple, but the storage capacity is limited
Solution Approach 1:
The patent transitions from a single-layer storage system to a multi-layer stacked configuration, adding the vertical dimension to the storage architecture. Multiple plates are stacked vertically to form multiple storage layers, allowing containers to be stored in three-dimensional space rather than just on a single plane, thereby significantly increasing storage capacity without proportionally increasing the footprint area.
Solution Approach 2:
The storage system is divided into multiple independent plates that can be stacked to form multiple layers. Each plate serves as an independent storage unit that can be individually positioned and accessed. This segmentation allows the system to scale storage capacity by adding or removing plates while maintaining structural modularity and operational flexibility.
2Quantity of substance
If multiple layers of plates are introduced, then storage capacity increases, but the driving mechanism becomes more complex
Solution Approach 1:
The driving unit is designed with a universal interface that can interact with multiple plates simultaneously or independently. The same driving mechanism can position any plate in the stack, and the plate structure is standardized across all layers, allowing a single driving system to control the entire multi-layer storage system without requiring separate mechanisms for each layer.
Solution Approach 2:
The patent introduces a standardized interface or intermediary mechanism between the driving unit and the plates. This intermediary allows the driving unit to reciprocate plates in the lateral direction without direct complex connections to each plate, simplifying the overall driving mechanism while enabling multi-plate control through a unified interface design.
3Ease of operation
If plates are reciprocated in lateral direction, then container access is improved, but positioning precision requirements increase
Solution Approach 1:
The system performs preliminary positioning actions by pre-establishing standardized guide rails and reciprocal paths for the plates. The driving unit is configured in advance to move plates along predetermined lateral trajectories, ensuring that containers are positioned in advance for optimal access. This preliminary arrangement reduces the need for high-precision real-time adjustments during container retrieval operations.
