Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional peeling method is used to remove the base layer from the film, then the peeling process can be completed, but the base layer may be damaged during peeling
Solution Approach 1:
The patent applies preliminary action by immersing the base layer and film stack in a peeling solution before the actual peeling operation. The solution softens the adhesive layer in advance, reducing the force required for peeling and preventing damage to the base layer during separation
Solution Approach 2:
The patent introduces a peeling solution as an intermediary substance between the base layer and the film. This solution penetrates the adhesive layer and acts as a lubricant or weakening agent, facilitating clean separation without direct mechanical stress on the base layer
2Manufacturing precision
If the peeling process is performed without proper preparation, then the process time is reduced, but the quality of peeling deteriorates
Solution Approach 1:
The peeling solution treatment is applied as a preliminary step that prepares the adhesive layer for easy separation. This pre-treatment ensures high-quality peeling by softening the adhesive, making the subsequent separation process clean and precise without requiring additional time for manual adjustment
Solution Approach 2:
The patent changes the physical-chemical parameters of the adhesive layer by exposing it to the peeling solution, which alters the adhesive properties to enable clean separation. This parameter change ensures high manufacturing precision in the peeling process
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 effectively reduces damage to the base layer during peeling, enhancing the reliability and efficiency of the process by using a controlled peeling method with temperature-adjusted solutions and mechanical manipulation to separate the base layer from the film.
Implementation Method 1
an adsorption device for adsorbing the base layer thereon to peel off the base layer from the film
Implementation Method 2
The first solution may include water having a temperature from about 50° C. to about 90° C.
Implementation Method 3
the first nozzle faces a peeling area of the lower surface when the base layer is bent to the second direction by the adsorption device and spray a second solution to the peeling area of the lower surface and the film
