Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels are physically and chemically affected during transfer processes in manufacturing, leading to changes in their characteristics.
Innovation Solution
A display panel transfer device with an absorber that maintains uniform surface tension by absorbing and moving the panel, using an absorption part, supporting part, and moving part to stabilize the panel during transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the display panel is transferred using conventional methods, then the transfer process can be completed, but the surface tension of the display panel becomes non-uniform due to physical and chemical effects during transfer
Solution Approach 1:
The patent introduces an absorber as an intermediary component that contacts the display panel during transfer. The absorber maintains uniform surface tension by providing a controlled interface between the panel and transfer mechanism, preventing direct harmful physical and chemical effects while enabling successful transfer.
Solution Approach 2:
The patent changes the surface tension parameter of the absorber to be uniform and controlled, which then transfers this uniform surface tension characteristic to the display panel during the absorption and transfer process, preventing non-uniform coating formation.
2Manufacturing precision
If the display panel is absorbed and moved during transfer, then uniform surface tension is maintained, but the device complexity increases due to additional absorption and supporting parts
Solution Approach 1:
The absorber serves multiple functions simultaneously: it contacts the display panel, maintains uniform surface tension, enables lifting, and facilitates transfer. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity despite the added capabilities.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures uniform surface tension and prevents non-uniform coating formation by maintaining consistent surface tension during the transfer process, ensuring uniform coating films on the display panel.
Implementation Method 1
the absorber may contact the display panel, and then may be combined with the display panel by providing a vacuum inside the absorber
