Adapter Plate Magazine for Wafer and PCB Stack Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magazine systems for flat substrates, such as wafers and printed circuit boards, lack flexibility and usability, as they are primarily designed for individual substrates rather than substrate stacks, leading to inefficiencies in storage and transport.
Innovation Solution
The magazine system incorporates adapter plates with mounting rails and locking elements that allow for easy adaptation to accommodate both individual substrates and stacks, featuring detachable and elastically displaceable components to secure and support substrate stacks, enabling flexible use and secure handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the magazine system is designed with fixed guide rails for individual substrates, then the substrate positioning is simple and reliable, but the system cannot accommodate substrate stacks
Solution Approach 1:
The side walls are made displaceable relative to each other, allowing the magazine system to dynamically adjust its internal width. This enables the same system to accommodate both individual substrates (narrow configuration) and substrate stacks (wide configuration), resolving the contradiction between adaptability and structural simplicity
Solution Approach 2:
The magazine system is segmented into movable side walls that can be independently displaced. This segmentation allows the system to be divided into different operational states (individual substrate mode vs. stack mode), enabling versatile accommodation without permanently increasing structural complexity
2Quantity of substance
If the magazine system is designed for individual substrates only, then the structure is simple, but the storage capacity and transport efficiency are limited
Solution Approach 1:
The magazine system is designed with universal side walls that can serve multiple functions: accommodating individual substrates, accommodating substrate stacks, and adjusting between these modes. This multi-functionality increases storage capacity without requiring entirely separate structures for different storage needs
Solution Approach 2:
The displaceable side walls enable the system to dynamically reconfigure its internal volume, allowing it to store varying quantities of substrates or stacks depending on the operational requirements, thereby increasing effective storage capacity without permanent structural additions
3Reliability
If adapter plates are made permanently fixed to side walls, then the attachment is secure, but the system loses flexibility for reconfiguration
Solution Approach 1:
The adapter plates incorporate displaceable locking elements that can switch between locked (secure attachment) and unlocked (reconfiguration enabled) states. This dynamic locking mechanism maintains attachment security during operation while enabling reconfiguration when needed
Solution Approach 2:
The locking elements are designed to be automatically engaged or disengaged through simple relative movements between the adapter plate and side wall, without requiring external tools or complex mechanisms. The system self-secures during assembly and self-releases during reconfiguration
4Reliability
If locking elements are made rigid and fixed, then the substrate securing is reliable, but the adapter plate cannot be easily assembled or disassembled
Solution Approach 1:
The locking elements are designed to be elastically displaceable, allowing them to be temporarily deformed during assembly/disassembly operations and then return to their rigid locking position during normal operation. This dynamic behavior provides both ease of operation and reliable substrate securing
Solution Approach 2:
The locking elements change their mechanical parameters (rigidity vs. flexibility) based on operational state. During assembly, they exhibit flexible behavior allowing easy manipulation; during substrate securing, they exhibit rigid behavior providing reliable locking. This parameter change enables both ease of operation and reliability

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows for efficient storage and transport of both individual substrates and stacks within the same magazine system, enhancing usability and flexibility by ensuring secure attachment and preventing accidental movement or detachment, thus improving operational efficiency.
Implementation Method 1
each adapter plate has at least one mounting hook for attachment to the respective side wall
Implementation Method 2
each adapter plate has at least one elastically displaceable locking element for positive locking to the side wall
Implementation Method 3
The locking element reliably prevents accidental detachment from the respective side wall
Implementation Method 4
the adapter plates each have one or more support rails on one side, which together form a support for a substrate stack when fastened to the side walls
Implementation Method 5
each drawer has two guide rails arranged at a distance from one another and parallel to one another on the side parts
Implementation Method 6
Optionally, damping elements are assigned to the mounting hook and/or the respective locking element, which act between the adapter plate and the respective side wall to prevent rattling noises and movements
