Solution Overview

Problem

Current transition protection elements, such as corrugated or bellows, are complex and costly to produce due to the need for different materials and designs to achieve specific mechanical properties, making it difficult to tailor mechanical properties for specific applications efficiently and inexpensively.

Innovation Solution

A fabric with distinct sections that differ in mechanical properties, achieved through material weakening, such as perforations or changes in yarn thickness, allowing for flexible adaptation of mechanical properties like flexural rigidity, elasticity, and tensile strength, using a single material or identical sections with varying weaknesses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different materials and designs are used to achieve specific mechanical properties in transition protection elements, then the mechanical properties can be tailored for specific applications, but the production complexity and costs increase

Engineering Contradiction:
Improvemechanical property tailoringVSAvoidproduction complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by creating distinct sections within a single fabric structure, where each section has different mechanical properties achieved through material weakening (perforations, slits, or reduced yarn density) in specific areas. This allows different parts of the transition protection element to have tailored mechanical properties without requiring multiple different materials or complex assemblies.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent merges multiple functional sections into a single integrated fabric structure. Instead of assembling multiple separate elements with different materials, the invention combines all sections into one fabric piece with varying mechanical properties achieved through selective material weakening, thereby reducing production complexity and assembly requirements.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If multiple different elements are assembled to produce corrugated bellows, then the required mechanical properties can be achieved, but the production becomes cost-intensive

Engineering Contradiction:
Improvemechanical property fulfillmentVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent creates a universal fabric structure that can fulfill multiple mechanical property requirements within a single element. By incorporating different sections with varying degrees of material weakening, a single fabric can serve multiple functional roles (rigid support in some areas, flexible deformation in others) without requiring multiple specialized components, thereby reducing production costs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes physical parameters of the fabric by introducing material weakening features (perforations, slits, reduced yarn density) in specific sections. This allows continuous adjustment of mechanical properties such as flexibility, rigidity, and deformability within the same base material, achieving the required performance without needing multiple different materials or expensive custom assemblies.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If made-to-measure corrugated bellows are produced, then the transition protection can be adapted to specific positions, but the production is complex

Engineering Contradiction:
Improveposition adaptationVSAvoidproduction efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent segments the fabric into distinct sections with different mechanical properties by applying material weakening to specific areas. This segmentation is achieved through standardized production techniques (selective perforation, slitting, or yarn density variation) that can be efficiently manufactured, allowing the fabric to be cut and configured for different positions without requiring entirely custom-made pieces, thus maintaining production efficiency.

Inventive Principle:
Principle #1Segmentation
