Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing tape cleaners are inconvenient to use, prone to misplacement, and have high manufacturing costs due to complex designs, with issues such as the adhesive tape roller separating during use and difficult adhesive replacement.

Innovation Solution

A tape cleaner design featuring an integrally formed adhesive tape roller and cover with a support roller, allowing 360° rotation of the rotary cover for easy access and replacement, and a handle for convenient use and storage, preventing the adhesive tape roller from separating and simplifying the replacement process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the adhesive tape roller and cover are separately stored in a case, then the adhesive tape roller can be replaced easily, but the cover is frequently lost or misplaced

Engineering Contradiction:

Improveease of replacementVSAvoidcover retention

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The adhesive tape roller is integrally formed with the cover as a single unit, eliminating the risk of the cover being lost or misplaced while maintaining the ability to replace the adhesive tape roller by detaching it from the support roller

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If the adhesive tape roller is integrally formed with the cover, then the cover is not lost, but the adhesive tape roller may separate during use

Engineering Contradiction:

Improvecover retentionVSAvoidroller attachment stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The adhesive tape roller is designed as a separate component that can be easily attached to and detached from the support roller, allowing the roller to be replaced when the adhesive is exhausted while the cover remains permanently attached to prevent loss

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If two gears and two rollers are used, then the adhesive tape can be wound and unwound, but the design is complicated and manufacturing cost is high

Engineering Contradiction:

Improvetape winding functionVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The complex gear mechanism is completely removed from the design. Instead of using gears and multiple rollers, the patent uses a simple support roller that rotates freely to allow the adhesive tape roller to be wound and unwound without any mechanical transmission components

Inventive Principle:

Principle #2Taking out (Extraction)

4Ease of operation

If the cover is permanently affixed to the tape cleaner, then storage is convenient and adhesive tape surface is protected, but adhesive tape replacement becomes difficult

Engineering Contradiction:

Improvestorage convenienceVSAvoidadhesive replacement ease

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

AI summary

The disclosed tape cleaner comprises an adhesive tape roller, a support roller inserted in the adhesive tape roller and supporting the adhesive tape roller, an upper cover having both sides connected to both sides of the support roller and partially covering the outer circumferential surface of the adhesive tape roller, a rotary cover having both sides connected to both sides of the support roller, partially covering the outer circumferential surface of the adhesive tape roller, on the inside of the upper cover, and rotatable by 360° in both directions about the longitudinal direction of the support roller, and a handle connected with the upper cover. Both the adhesive tape roller and the support roller rotate about the longitudinal direction of the support roller, and the adhesive tape roller, the support roller, the upper cover and the rotary cover are all attachable and detachable.
