Solution Overview

Problem

Traditional grinding wheels using liquid adhesives face issues such as overspill, uneven attachment, and reduced abrasive element life due to excess adhesive and uneven thickness application.

Innovation Solution

The use of double-sided adhesive tape with an even thickness of adhesive to attach abrasive elements to the base disk, eliminating overspill and ensuring even attachment, thereby maintaining the integrity and longevity of the abrasive elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If liquid adhesive is applied to attach abrasive elements to the base disk, then the abrasive elements can be securely bonded, but excess adhesive overspills and forms gaps between adjacent elements causing vibration

Engineering Contradiction:

Improvebond strengthVSAvoidvibration from adhesive gaps

Core Design Contradiction:

StrengthVSObject-generated harmful factors

Solution Approach 1:

The patent applies a thin film adhesive layer (adhesive tape) instead of bulk liquid adhesive. This thin film configuration prevents overspilling while maintaining bonding strength, and eliminates the formation of gaps between abrasive elements that cause vibration during operation.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent changes the physical state and application method of the adhesive from liquid to a controlled thin film form. This parameter change allows precise control of adhesive thickness and distribution, preventing both overspilling and insufficient bonding.

Inventive Principle:

Principle #35Parameter changes

2Strength

If excess liquid adhesive is applied to ensure maximum contact area, then bonding strength increases, but abrasive element thickness is reduced due to removal of adhesive-contaminated portions

Engineering Contradiction:

Improvebond strengthVSAvoidabrasive element life

Core Design Contradiction:

StrengthVSDuration of action of moving object

Solution Approach 1:

The thin film adhesive tape provides sufficient bonding strength without requiring excess adhesive application. Since the adhesive is contained within the tape structure, there is no overspilling onto the abrasive surface, eliminating the need to remove abrasive material and preserving element thickness and service life.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent uses precisely the right amount of adhesive through the thin film tape, avoiding both insufficient bonding and excessive adhesive application. This partial action approach achieves optimal bonding without the harmful effects of excess adhesive.

Inventive Principle:

Principle #16Partial or excessive action

3Ease of manufacture

If liquid adhesive is applied unevenly, then assembly process is simpler, but abrasive elements are attached at different distances requiring removal of protruding portions

Engineering Contradiction:

Improveadhesive application simplicityVSAvoidabrasive element alignment

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The thin film adhesive tape inherently provides uniform thickness across the entire attachment surface. This uniformity ensures that all abrasive elements are attached at the same distance from the base disk, eliminating alignment issues and the need for subsequent material removal, while the tape can be easily applied.

Inventive Principle:

Principle #30Flexible shells and thin films

4Strength

If more liquid adhesive is applied to fill surface irregularities, then contact surface increases and bonding improves, but adhesive contamination of abrasive surfaces increases

Engineering Contradiction:

Improvebonding strengthVSAvoidabrasive material removal

Core Design Contradiction:

StrengthVSLoss of substance

Solution Approach 1:

The thin film adhesive tape is designed with controlled thickness to fill surface irregularities without overspilling onto the abrasive surfaces. The tape structure contains the adhesive within defined boundaries, providing sufficient contact area for bonding while preventing contamination of the abrasive working surfaces.

Inventive Principle:

Principle #30Flexible shells and thin films
