Adhesive Decorative Pattern With Plurable Polymer Film
Solution Overview
Problem
Existing decorative elements with thermoplastic polyurethane films lack tensile strength and can only withstand unidirectional forces, causing design distortion under tensile stress.
Innovation Solution
A method involving stacking first and second pliable polymer films, a fabric decorative element with irregular fibers, and a releasing paper coated with a glue layer, which are bonded together using hot pressing to create an adhesive decorative pattern that can withstand tensile forces in multiple directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a thermoplastic polyurethane film is used for decorative elements, then the film provides flexibility and ease of application, but it lacks tensile strength and cannot withstand tensile forces in different directions
Solution Approach 1:
The patent applies composite materials by combining thermoplastic polyurethane films with fabric layers to create a hybrid structure. The fabric provides tensile strength in multiple directions while the thermoplastic film maintains flexibility and ease of application. This composite approach resolves the contradiction by integrating the advantages of both materials.
Solution Approach 2:
The patent applies local quality by selectively placing fabric layers at specific orientations (different directions) within the decorative element structure. Each fabric layer is positioned to provide tensile strength in particular directions, creating localized reinforcement that collectively addresses multi-directional stress requirements while preserving overall flexibility.
2Ease of manufacture
If decorative lines are patterned parallel to one another, then the design is simple to manufacture, but it can only withstand unidirectional tensile force and distorts under other directions
Solution Approach 1:
The patent applies asymmetry by orienting fabric layers at different angles and directions rather than using parallel alignment. This asymmetric arrangement of fabric grains and orientations allows the decorative element to withstand tensile forces from multiple directions, preventing distortion while maintaining manufacturing feasibility through layered construction.
Solution Approach 2:
The patent combines multiple fabric layers with different orientations with the thermoplastic film to create a composite structure. This composite approach enables the decorative element to maintain design integrity under multi-directional stress while still being manufacturable through standard lamination processes.
3Strength
If multiple layers are stacked and hot pressed to bond the decorative element, then tensile strength in multiple directions is achieved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the decorative element into distinct functional layers (thermoplastic films, fabric layers, adhesive layers) that can be manufactured and prepared separately, then assembled through hot pressing. This segmentation allows each layer to be optimized for its specific function while simplifying the overall manufacturing process through modular construction.
Solution Approach 2:
The patent merges multiple layers with different functions (structural, decorative, adhesive) into a single integrated decorative element through hot pressing. This combining process achieves multi-directional tensile strength while consolidating the manufacturing steps into a standardized lamination process, balancing strength requirements with process feasibility.

AI summary
An adhesive decorative pattern with a pliable polymer film includes first and second pliable polymer films, a first decorative element made out of fabric and consisting of a plurality of fabrics each extending in irregular directions, and a releasing paper defining a front releasably coated with a glue layer. The first pliable polymer film, the first decorative element, the second pliable polymer film, and the releasing paper are stacked together into a pile. The first decorative element is sandwiched between the first and second pliable polymer films. The glue layer is sandwiched between the second pliable polymer and the front of the releasing paper. The adhesive decorative pattern with the pliable film includes the first pliable polymer film, the first decorative element, and the second pliable polymer film bonded securely together, and includes the releasing paper being able to be released from the glue layer.
