Solution Overview

Problem

Dual-space woven fabric products, used for manufacturing boats, face limitations in versatility due to vertically interlaced interval maintaining yarns, which require post-processing for cutting and result in poor user sleeping stability under load.

Innovation Solution

A three-dimensional string woven air cushion with interval maintaining yarns interlaced in a zigzag manner between lower and upper sheet layers, using a punching needle part, to maintain a predetermined interval and prevent eccentric distortion, allowing for easier cutting and improved cushioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If interval maintaining yarns are vertically interlaced between lower and upper sheet layers, then the structure is simple and manufacturing is easy, but the upper sheet layer distorts in one direction under load causing poor sleeping stability

Engineering Contradiction:
Improveease of manufactureVSAvoidsleeping stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The interval maintaining yarns are configured to extend in multiple directions (zigzag pattern) rather than vertically, creating an asymmetric distribution that prevents one-directional distortion and improves sleeping stability while maintaining manufacturing simplicity

Inventive Principle:
Principle #4Asymmetry

2Reliability

If the dual-space woven fabric product is manufactured for boat manufacturing, then it has strong durability and ease of assembly, but it is limited in purposes and requires post-processing for cutting

Engineering Contradiction:
ImprovedurabilityVSAvoidversatility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The three-dimensional string woven structure with multi-directional interval maintaining yarns creates a versatile product that can be applied to both boat manufacturing and mattress cushions, eliminating the limitation to single-purpose applications while maintaining durability

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

3Productivity

If vertically interlaced interval maintaining yarns are used, then the manufacturing process is simple, but post-processing is required to cut unnecessary yarns and finish lateral surfaces

Engineering Contradiction:
ImproveproductivityVSAvoidease of manufacture
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The interval maintaining yarns are pre-configured in a multi-directional zigzag pattern during the weaving process, which eliminates the need for subsequent cutting and finishing operations, thereby improving productivity while maintaining ease of manufacture

Inventive Principle:
Principle #10Preliminary action
