Solution Overview
Problem
Existing methods for promoting crazing in polymer materials are not efficient in continuously increasing the polymer surface area through simultaneous solvent application and tensile force application.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If solvent application and tensile force application are performed separately, then the process is simple to operate, but the efficiency of increasing polymer surface area is low
Solution Approach 1:
The patent combines solvent application and tensile force application into a single integrated apparatus. The solvent application assembly and tensile force application assembly work simultaneously on the polymer material in sequence, allowing both processes to occur in one continuous operation rather than as separate steps, thereby提高效率 while maintaining operational simplicity
Solution Approach 2:
The apparatus enables continuous processing where the polymer material continuously passes through the solvent application assembly and then the tensile force application assembly. This continuous action eliminates idle time between solvent application and tensile force application, maximizing the efficiency of surface area increase while maintaining a streamlined process
2Productivity
If solvent application and tensile force application are applied simultaneously and continuously, then the productivity increases, but the device complexity increases
Solution Approach 1:
The apparatus is divided into distinct functional assemblies: a solvent application assembly with solvent reservoir and application mechanism, and a tensile force application assembly with tensioning rollers. This segmentation allows each assembly to be optimized independently while working together in sequence, enabling continuous processing without excessive overall complexity
Solution Approach 2:
The patent transitions from sequential batch processing to continuous simultaneous processing by adding the dimension of continuous material flow. The polymer material moves continuously through both assemblies, enabling simultaneous solvent application and tensile force application without proportionally increasing device complexity

Function Achieved in This Case
The apparatus effectively promotes crazing in polymer materials by continuously applying solvent and tensile force, significantly increasing the polymer surface area and enhancing material properties for testing and manufacturing purposes.
Implementation Method 1
wetting rollers with an absorbent outer surface
Implementation Method 2
the solvent that is selected is one that is identified to have the ability to selectively dissolve a portion of a selected polymer material surface
Implementation Method 3
a second assembly that receives the polymer material now having solvent at the surface. The second assembly then continuously applies a tensile force to the polymer material having solvent at the surface thereby leading to crazing
Implementation Method 4
Crazing is the creation of a network of surface discontinuities
