Solution Overview

Problem

Conventional agents/primers fail to ensure sufficient adhesion between a porous basic frame and industrial clay, particularly in semi-automatic and fully automatic application processes, leading to reduced bonding and contamination issues.

Innovation Solution

A coating agent comprising a base wax portion with a melting range below 80°C and a synthetic wax portion with a higher melting point, combined with optional additives like rheological additives, tackifiers, and colorants, is applied to the basic frame, allowing for increased adhesion when heated by the industrial clay, forming a strong bond without a lubricant film.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional agents/primers are used to improve adhesion between basic frame and industrial clay, then adhesion is enhanced, but they fail to provide sufficient adhesion in semi-automatic and fully automatic application processes

Engineering Contradiction:

Core Design Contradiction:
StrengthVSExtent of automation

Solution Approach 1:

The patent changes the chemical composition parameters of the coating agent by combining silane-based primers with specific wax components (paraffin wax, microcrystalline wax, and/or polyalphaolefin wax) in defined ratios. This parameter modification enables the coating to provide sufficient adhesion in automated application processes where conventional primers fail, resolving the contradiction between adhesion strength and automation compatibility

Inventive Principle:

Solution Approach 2:

The patent creates a composite coating agent by combining silane-based primer components with wax components (paraffin wax, microcrystalline wax, and/or polyalphaolefin wax) in specific weight ratios (20-70% silane, 30-80% wax). This composite formulation synergistically provides both strong adhesion properties and compatibility with automated application processes, resolving the technical contradiction between adhesion strength and automation extent

Inventive Principle:

2Ease of operation

If semi-automatic application system is used to apply clay, then application process is simplified, but adhesion between clay and basic frame is significantly reduced

Engineering Contradiction:
Improveease of clay applicationVSAvoidadhesion between clay and basic frame
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The patent modifies the coating agent composition by incorporating specific wax components (paraffin wax, microcrystalline wax, and/or polyalphaolefin wax) in optimized ratios alongside silane-based primers. These parameter changes enable the coating to maintain strong adhesion even when applied through semi-automatic systems that cannot exert high pressure, thus resolving the contradiction between ease of operation and adhesion strength

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces a specially formulated coating agent as an intermediary layer between the basic frame and industrial clay. This intermediary contains wax components that create optimal bonding conditions, enabling strong adhesion to be achieved even with reduced application pressure from semi-automatic systems, thus resolving the contradiction between ease of operation and adhesion strength

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If barrier layer such as shellac is applied to basic frame, then dust contamination is prevented, but adhesion between clay and basic frame is reduced

Engineering Contradiction:

Solution Approach 1:

The patent replaces the conventional shellac barrier layer with a composite coating agent containing silane-based primers and specific wax components in defined ratios. This composite formulation simultaneously provides dust barrier functionality and maintains strong adhesion properties, resolving the contradiction between contamination protection and adhesion strength that plagues conventional shellac-based solutions
