Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for attaching a sheet member to a cylinder body often result in damage to the sheet member during the wrapping process, particularly when its inner surface comes into contact with the apparatus body.

Innovation Solution

A method involving preliminary fixation of the sheet member's ends to fixation portions on the cylinder body, with an installation member placed between the apparatus body and the sheet member's inner surface before wrapping, allowing the sheet member to be rotated around the cylinder body without direct contact with the apparatus body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the sheet member is wrapped around the cylinder body without an installation member, then the wrapping process is simpler, but the sheet member suffers damage due to direct contact with the apparatus body

Engineering Contradiction:

Improvewrapping process complexityVSAvoiddamage to sheet member

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

An installation member is introduced as an intermediary component between the apparatus body and the sheet member during the wrapping process. This installation member has a smooth surface that prevents direct contact between the sheet member and the apparatus body, thereby eliminating damage to the sheet member while maintaining a relatively simple wrapping process

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If the sheet member directly contacts the apparatus body during wrapping, then the apparatus structure is simpler, but the sheet member durability decreases

Engineering Contradiction:

Improveapparatus structureVSAvoidsheet member durability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The installation member serves as a protective intermediary that is temporarily installed on the apparatus body during the wrapping process. This intermediary component protects the sheet member from damage caused by direct contact with the apparatus body, thereby improving sheet member durability while adding only minimal structural complexity to the apparatus

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If the sheet member is wrapped without preliminary fixation, then the initial setup is faster, but the wrapping process becomes unstable and causes damage

Engineering Contradiction:

Improveinitial setup speedVSAvoidwrapping stability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The first end portion of the sheet member is preliminarily fixed to the first fixation portion of the cylinder body before the wrapping process begins. This preliminary fixation stabilizes the sheet member during wrapping, preventing instability and damage, while the fixation portions are designed to enable quick attachment and detachment, maintaining reasonable setup speed

Inventive Principle:

Principle #10Preliminary action

AI summary

A method for attaching a sheet member to a cylinder body includes: preliminarily fixing a first end portion of the sheet member to a first fixation portion of a cylinder body provided in an apparatus body and having a substantially circular cross section; wrapping the sheet member around the cylinder body by rotating the cylinder body; fixing the first end portion and a second end portion of the sheet member to the first fixation portion and a second fixation portion, respectively; and installing an installation member between the apparatus body and an inner surface of the sheet member before the wrapping of the sheet member around the cylinder body.
