Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional modeling materials (polyvinyl chloride with filler and plasticizer) are used, then the material can be deformed and hardened by heating, but the surface becomes smooth and reflects the tool structure without automatic texture formation
Solution Approach 1:
The invention incorporates fillers with predetermined surface structures (leather grain, embossing patterns, etc.) into the modeling material before the modeling process. These pre-prepared structured fillers are mixed with the plastisol binder and plasticizer to create a composite material that automatically transfers its structure to the surface during modeling, eliminating the need for subsequent texturing operations.
Solution Approach 2:
The invention uses structured fillers as intermediary carriers that transfer their pre-formed surface structures to the modeling material during the mixing and modeling process. These fillers act as mediators between the desired surface texture and the final product, allowing structure transfer without requiring specialized texturing tools or additional processing steps.
2Shape
If fiber materials and cellulose fibers are added to plastisol, then the material becomes suitable for modeling, but it forms smooth surfaces without structures during modeling
Solution Approach 1:
The invention distinguishes between different functional requirements of fillers: bulk fillers (cellulose fibers, inorganic powders) provide structural integrity and deformability, while surface fillers (structured particles with embossing patterns, leather grain textures) provide surface texture. By assigning different qualities to different filler components, the material achieves both workability and automatic surface structuring.
Solution Approach 2:
The invention creates a composite modeling material combining multiple filler types with distinct functions: cellulose fibers and inorganic fillers for bulk properties, plus specially structured surface fillers for texture formation. This multi-component composite approach allows simultaneous achievement of deformability, structural integrity, and automatic surface texturing without excessive filler content.
3Shape
If additional tools and aids are used to create surface structures, then leather-like effects can be reproduced, but the manufacturing process becomes more complex
Solution Approach 1:
The invention enables the modeling material to self-structure during the modeling process itself. The structured fillers embedded in the material automatically transfer their surface patterns to the workpiece as it is being shaped and manipulated, without requiring separate texturing tools, embossing devices, or post-processing equipment. The material serves its own texturing function.
Solution Approach 2:
The invention merges the modeling function and surface texturing function into a single integrated process. By incorporating pre-structured fillers into the material matrix, the act of modeling simultaneously achieves both shaping and surface texturing, combining what were previously separate operations into one unified process that eliminates the need for specialized texturing tools.
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 material automatically creates a visually and haptically textured surface, replicating leather-like characteristics without additional processing steps, offering high flexibility and stability.
Implementation Method 1
The binder used consists essentially of plastisol. This plastisol is essentially composed of PVC and plasticizer... which upon hardening, forms a structured surface resembling leather
Implementation Method 2
the addition of branched plastic fibers as fillers in modeling material mixtures before the hardening process forms a structured surface design that can be perceived visually and/or haptically
