Solution Overview

Problem

Existing methods for attaching adhesive tapes to annular frames often result in damage to the frames due to cutting, leading to reduced usability and difficulty in peeling the tape after use, as adhesive residue is left behind.

Innovation Solution

A tape attaching method and apparatus that involves positioning an adhesive tape larger than the frame with a spacing, using a roller to partially attach the tape to the frame without direct contact, and a cutter to cut the tape outside the frame's contact area, utilizing a roller with hard and soft areas to manage attachment and cutting effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the adhesive tape is fully attached to the frame by pressing with a roller and then cut along the frame, then the workpiece can be securely fixed to the frame, but the frame may be damaged by the cutter and adhesive residue remains on the frame

Engineering Contradiction:

Improveworkpiece fixation reliabilityVSAvoidframe damage and adhesive residue

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The adhesive tape attachment is divided into two distinct zones: a first attachment area where the tape is fully pressed against the frame for secure fixation, and a second attachment area where the tape is spaced from the frame to allow clean cutting. This segmentation allows the tape to be securely attached where needed while avoiding damage and residue in other areas.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The harmful cutting action is extracted from the frame contact area. The cutter operates only in the second attachment area where the tape is spaced from the frame, completely separating the cutting operation from the frame to eliminate frame damage and adhesive residue while maintaining secure fixation in the first area.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If the adhesive tape is fully attached to the frame, then the workpiece is securely fixed, but the adhesive tape cannot be easily peeled from the frame after use

Engineering Contradiction:

Improveworkpiece fixation reliabilityVSAvoidtape peeling ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The adhesive tape is divided into a first attachment area that is fully pressed against the frame for secure workpiece fixation, and a second attachment area that is spaced from the frame. This segmentation allows the tape to be securely attached where the workpiece is located while creating a peeling initiation area in the second zone where the tape can be easily separated from the frame without adhesive residue.

Inventive Principle:

Principle #1Segmentation

3Ease of manufacture

If the cutter contacts the frame during cutting, then the adhesive tape can be cut along the frame, but the frame is damaged reducing its number of repetitions of use

Engineering Contradiction:

Improvetape cutting easeVSAvoidframe durability and reusability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The cutting operation is extracted from the frame contact area and relocated to the second attachment area where the adhesive tape is spaced from the frame. The cutter cuts the tape in this elevated position without contacting the frame, completely eliminating frame damage while maintaining effective tape cutting capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The cutting operation is moved from the horizontal plane (where the cutter would contact the frame) to a different vertical position above the frame. By spacing the tape from the frame in the second attachment area, the cutter can operate in this elevated dimension to cut the tape without interfering with the frame structure.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A tape attaching method for mounting an adhesive tape to an annular frame having an inside opening to thereby support a plate-shaped workpiece through the adhesive tape to the frame in the inside opening thereof. The tape attaching method includes an adhesive tape attaching step of attaching the adhesive tape to the workpiece, the adhesive tape being larger in size than the frame, a frame positioning step of positioning the frame with a spacing defined between the frame and the adhesive tape in the condition where the inside opening of the frame is opposed to the workpiece attached to the adhesive tape, and a tape attaching and cutting step of partially pressing the adhesive tape against the frame by using a roller rotating along the inner circumference of the frame defining the inside opening.
