Solution Overview

Problem

Thermoplastic films used in commercial and consumer products face challenges in maintaining strength and consumer perception due to increased transparency and perceived weakness when thinned for cost reduction, leading to decreased consumer value and potential purchase deterrence.

Innovation Solution

Implementing a gradient deformation pattern in thermoplastic films, where deformations are arranged in shapes or repeat units that increase or decrease in size along the film, providing a reinforced appearance and increased elasticity or strength, thereby making thinner films appear thicker and more valuable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If thermoplastic films are thinned to reduce material usage and production costs, then production costs are reduced, but the films become more transparent and consumers perceive them as weaker, leading to decreased consumer value

Engineering Contradiction:
Improveamount of thermoplastic materialVSAvoidperceived strength
Core Design Contradiction:
Quantity of substanceVSStrength

Solution Approach 1:

The patent applies optical effects through deformation patterns that manipulate light reflection and refraction. The gradient deformation patterns create visual illusions of thickness and strength by altering how light interacts with the film surface, making thin films appear thicker and stronger without adding material.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent introduces three-dimensional deformation patterns on a two-dimensional film surface. By creating raised and recessed regions with varying depths and sizes arranged in gradient patterns, the film gains apparent thickness and structural complexity in the visual dimension, resolving the contradiction between thin physical thickness and perceived strength.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If thermoplastic films are stretched to increase surface area, then the amount of film needed for a given product size is reduced, but the films become thinner and more transparent, leading to consumer dissatisfaction

Engineering Contradiction:
Improvesurface areaVSAvoidperceived strength
Core Design Contradiction:
Area of stationary objectVSStrength

Solution Approach 1:

The deformation patterns create optical effects that mask the thinness resulting from stretching. By manipulating light reflection through varied surface topography, the film maintains perceived opacity and strength even after stretching increases surface area coverage.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent uses curved and rounded deformation features rather than sharp angles. The gradient deformation patterns include rounded peaks and valleys that create smooth optical transitions, enhancing the perception of thickness and structural integrity while allowing the stretched film to maintain aesthetic appeal.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Ease of manufacture

If uniform deformation patterns are applied across the film, then manufacturing is simplified, but the film lacks localized elasticity and strength variations needed for different functional requirements

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidlocalized elasticity
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent implements gradient deformation patterns where the size, depth, and density of deformations vary systematically across different regions of the film. This creates localized areas with different mechanical properties - for example, larger deformations in regions requiring higher elasticity and smaller deformations in regions requiring more stability - while still using a single manufacturing process.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The deformation patterns are designed to be dynamic in response to applied forces. The gradient structure allows different regions to deform at different rates and magnitudes under load, providing adaptive mechanical behavior that uniform patterns cannot achieve, while maintaining manufacturing efficiency through a single-pass deformation process.

Inventive Principle:
Principle #15Dynamics

AI summary

Thermoplastic films and bags include gradient patterns of post-formation deformations. The gradient patterns of post-formation deformations can provide a connotation of strength. Additionally, the gradient pattern of post-formation deformations can provide different areas of the films or bags with different physical characteristics such as tear resistance, puncture resistance, elasticity, etc.
