Solution Overview

Problem

Conventional methods for producing friction linings and brake linings face inefficiencies due to temperature fluctuations and energy inefficiencies in heating steel pressing tools, leading to slow processing times and inconsistent product quality.

Innovation Solution

The use of ceramic heating plates to heat the die and mirror plate directly, with insulation to prevent heat transfer to metal components, allowing for precise temperature control and faster heating times, along with optional profile plates for additional mechanical support and wear resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If steel pressing tools (die and mirror plate) are heated electrically using conventional heating methods, then the friction lining mixture can be processed, but temperature fluctuations occur and heating times are slow

Engineering Contradiction:

Improvetemperature control precisionVSAvoidheating time

Core Design Contradiction:

TemperatureVSLoss of time

Solution Approach 1:

The patent changes the heating method from conventional electrical heating of steel tools to infrared radiation heating. This parameter change in the heating mechanism enables rapid heating with minimal temperature fluctuations, directly resolving the contradiction between temperature control precision and heating time.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the mechanical/electrical heating system with an optical/infrared heating system. The infrared radiation directly heats the friction lining mixture without requiring extensive heating of the steel tooling, thereby reducing heating time while maintaining precise temperature control.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If steel pressing tools are heated to process friction linings, then the binding agents can solidify and cross-link the mixture, but large amounts of energy are consumed heating the steel tooling

Engineering Contradiction:

Improvebonding strengthVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by stationary object

Solution Approach 1:

The patent changes the heating approach from bulk heating of steel tools to direct infrared heating of the friction lining mixture. This enables the binding agents to solidify and cross-link at the required temperature while minimizing energy wasted on heating the steel tooling, thus reducing energy consumption while maintaining bonding strength.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent converts the previously harmful energy loss (heating unnecessary steel mass) into a beneficial process by using infrared radiation that selectively heats only the friction lining mixture. This transforms energy that was wasted into energy that directly contributes to the curing process.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Manufacturing precision

If conventional electrical heating is used for the pressing tool, then the friction lining can be produced, but temperature uniformity across the surface is poor

Engineering Contradiction:

Improvetemperature uniformityVSAvoidproduction speed

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The patent replaces conventional electrical heating with infrared radiation heating, which provides superior temperature uniformity across the friction lining surface. This uniform heating enables faster processing speeds without sacrificing manufacturing precision, thereby resolving the contradiction between temperature uniformity and production speed.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
