Solution Overview

Problem

Existing crop protection nets face difficulties in installation, deformation, and tension adjustment, which affect their effectiveness in shielding against bad weather and insects, and are costly to manufacture and implement.

Innovation Solution

A protective net with linear fixing means that have longitudinal freedom, allowing for easy positioning and adjustment, and are integrated using a stretch-knitted design with buttonholes for cable fixation, enabling flexible installation and reduced manufacturing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional nets are hung on standard supports with fixed connections, then the net structure is stable, but the installation is complex and tension adjustment is difficult

Engineering Contradiction:
Improveinstallation simplicityVSAvoidnet structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The net is divided into modular panels with integrated buttonholes at regular intervals, allowing the net to be segmented and reconfigured on different support structures without requiring complex custom installation for each application

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The linear fixing means (cables) are made movable relative to the net through the buttonhole mechanism, allowing dynamic adjustment of tension and positioning during installation and operation, transforming the static fixed-connection system into a dynamic adjustable system

Inventive Principle:
Principle #15Dynamics

2Reliability

If the net uses fixed connection with supports, then the net maintains its shape, but deformation occurs due to inadequate tension adjustment

Engineering Contradiction:
Improveprotection effectivenessVSAvoidtension adjustment capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cable-fixing system allows dynamic adjustment of tension by moving the cable through the buttonholes, enabling the net to maintain proper tension and shape under varying weather conditions and loads while remaining easy to adjust

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system allows changing the tension parameter and positioning parameter of the net by adjusting the cable position in the buttonholes, enabling adaptation to different support configurations and weather conditions while maintaining structural integrity

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If the net is made with integrated linear fixing means, then the manufacturing cost is reduced, but the net has limited mobility in the longitudinal direction

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidlongitudinal adjustment freedom
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The net is manufactured as modular panels with regularly spaced buttonholes, allowing the fixing means to be positioned at different longitudinal locations while maintaining a simple standardized manufacturing process

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The buttonhole acts as an intermediary element between the fixed net structure and the movable cable, providing a simple manufactured feature that enables longitudinal adjustment freedom without complicating the net's manufacturing

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The invention relates to a net for protecting fruit and market-garden plantations, other than nurseries, from the sun and from inclement weather, particularly against hail or rain, including at least one linear means (4) for attaching onto two or more holders. Said net defines substantially aligned buttonholes (6), provided in the form of through-holes (6) or blind holes, at which said linear attachment means (4) is free of any fixed and firm connection with the net.
