Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional ink pouch storage bodies for inkjet printers require complex configurations to cover ink pouches filled with ultraviolet-curable ink, leading to increased manufacturing costs.

Innovation Solution

A pouch storage body with a simple configuration that includes a tubular storage housing and a stored structure with front and rear wall portions, along with extension portions to cover the ink pouch, made of resin or coated cardboard, reducing manufacturing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a complex configuration is used to cover the ink pouch in all directions, then the ink pouch is fully protected from ultraviolet light, but manufacturing costs increase

Engineering Contradiction:

Improveultraviolet light exposure protectionVSAvoidmanufacturing cost

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The pouch storage body is divided into multiple wall portions (front, rear, left, right, upper, lower) that can be integrally molded but function as separate protective segments. Each wall portion covers a specific direction, collectively providing complete protection while allowing simplified manufacturing through integral molding

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The pouch storage body serves multiple functions simultaneously: it stores the ink pouch, protects it from ultraviolet light in all directions, and provides structural support. The single molded structure performs all these functions without requiring additional components, reducing manufacturing complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of manufacture

If a simple configuration is used to reduce manufacturing costs, then manufacturing costs decrease, but the ability to cover the ink pouch in all directions is compromised

Engineering Contradiction:

Improvemanufacturing costVSAvoidultraviolet light exposure protection

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

Multiple wall portions that would traditionally require separate manufacturing and assembly are merged into a single integrally molded pouch storage body. This combining of functions into one component simplifies manufacturing while ensuring complete coverage of the ink pouch in all directions without gaps

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The design changes the structural parameters of the pouch storage body by creating a hollow box-shaped structure with specific wall thickness and configuration. This optimized structure provides maximum protection with minimum material usage, achieving both cost reduction and complete coverage

AI summary

A pouch storage body includes a storage housing with a tubular shape, and a stored structure to be stored in the storage housing, together with an ink pouch. The stored structure includes a front wall portion to cover a front portion of a bag portion of the ink pouch from a front except for a supply portion, a rear wall portion to cover a rear portion of the bag portion of the ink pouch from a rear, and a connecting portion to connect the front wall portion and the rear wall portion.
