Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional binding tapes are prone to tearing when used for agricultural crops with high repulsive forces, such as branches in fruit trees, and lack stability on core rods of diverse diameters, requiring manual labor and specialized skills for binding.

Innovation Solution

A binding tape with an intermediate layer featuring angled first linear members and optional second linear members, sandwiched between surface layers, enhances strength and stability, and a reel with flexible protrusions for secure support on varying core diameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional binding tapes are used for agricultural crops with high repulsive forces, then the binding operation can be performed, but the tape is prone to tearing

Engineering Contradiction:

Improvetape strengthVSAvoidtape durability

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The binding tape is constructed as a composite material consisting of a non-woven fabric base layer combined with a mesh layer having a grid-like structure. This composite structure combines the tensile strength of the non-woven fabric with the structural rigidity and tear resistance of the mesh layer, enabling the tape to withstand high repulsive forces from crop branches without tearing during binding operations

Inventive Principle:

Principle #40Composite materials

2Reliability

If manual binding operations are performed to ensure reliability, then binding strength can be maintained, but labor intensity and skill requirements increase

Engineering Contradiction:

Improvebinding reliabilityVSAvoidoperation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The binding tape is designed with self-tightening properties where the loop structure automatically adjusts and secures itself around crop branches during the binding process. The tape's composite structure provides friction and mechanical interlocking that maintains binding reliability without requiring manual adjustment or specialized operator skills, enabling automated or semi-automated binding operations

Inventive Principle:

Principle #25Self-service

3Ease of operation

If the tape loop is stretched to bind crops, then binding function is achieved, but the tape may tear under high repulsive forces

Engineering Contradiction:

Improvebinding flexibilityVSAvoidtape tensile strength

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The combination of non-woven fabric and mesh layer creates a composite structure where the non-woven fabric provides elasticity and stretchability for easy loop formation, while the mesh layer maintains tensile strength and prevents tearing when the tape is stretched around crop branches with high repulsive forces

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The mesh layer is structured with a grid pattern that allows localized deformation and stress distribution when the tape is stretched. The segmented grid structure enables the tape to extend and conform to crop branches while distributing tensile forces across multiple mesh intersections, preventing concentration of stress that would cause tearing

Inventive Principle:

Principle #1Segmentation
