Pulling rib and manufacturing process thereof and inflatable product

Solution Overview

Problem

The existing manufacturing process for pulling ribs in inflatable products involves complete gluing, which increases the cost and weight of the products and can block air current circulation, affecting inflation and deflation efficiency.

Innovation Solution

A manufacturing process that involves weaving dense and patterned regions with different densities, applying glue locally, and cutting to form pulling ribs, which reduces material waste and weight while maintaining structural integrity and ventilation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complete gluing is applied to the surface of pulling ribs, then structural integrity and durability are improved, but cost and weight of the inflatable product increase

Engineering Contradiction:

Improvestructural integrityVSAvoidweight of pulling rib

Core Design Contradiction:

ReliabilityVSWeight of stationary object

Solution Approach 1:

The patent applies different weaving densities to different regions of the pulling rib: a dense weaving region at the ends for structural integrity and connection, and a patterned weaving region in the middle for weight reduction and air circulation. This local differentiation allows the pulling rib to maintain reliability where needed while reducing overall weight and cost.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The pulling rib is divided into functionally distinct segments: dense weaving regions at the ends for connection and patterned weaving region in the middle for ventilation and weight reduction. This segmentation allows each part to be optimized for its specific function, avoiding complete gluing while maintaining structural integrity at critical connection points.

Inventive Principle:

Principle #1Segmentation

2Reliability

If complete gluing is applied to the surface of pulling ribs, then durability is improved, but manufacturing cost increases

Engineering Contradiction:

ImprovedurabilityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies different weaving densities to different regions of the pulling rib: a dense weaving region at the ends for structural integrity and connection, and a patterned weaving region in the middle for weight reduction and air circulation. This local differentiation allows the pulling rib to maintain reliability where needed while reducing overall weight and cost.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Instead of applying complete gluing to the entire surface, the patent uses partial gluing only on the dense weaving regions at the ends where structural integrity is critical. This partial action approach reduces material consumption and manufacturing cost while maintaining durability at the most critical connection points.

Inventive Principle:

Principle #16Partial or excessive action

3Shape

If pulling ribs are added to the interior of inflatable products, then shaping and support functions are improved, but air current circulation is blocked and inflating/deflating efficiency deteriorates

Engineering Contradiction:

Improveshaping functionVSAvoidinflating and deflating efficiency

Core Design Contradiction:

ShapeVSProductivity

Solution Approach 1:

The patent employs a patterned weaving region with lower weaving density in the middle portion of the pulling rib, creating a porous structure that allows air to pass through. This porous design enables the pulling rib to maintain its shaping and support functions while simultaneously allowing air current circulation, thus improving inflating and deflating efficiency.

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The pulling rib is divided into functionally distinct segments: dense weaving regions at the ends for connection and patterned weaving region in the middle for ventilation and weight reduction. This segmentation allows each part to be optimized for its specific function, avoiding complete gluing while maintaining structural integrity at critical connection points.

Inventive Principle:

Principle #1Segmentation
