Solution Overview

Problem

Electronic components are vulnerable to high temperatures during manufacturing processes like overmolding, which can damage them, and existing thermal insulation methods may not adequately protect against excessive heat exposure.

Innovation Solution

A method using ceramic thermal insulation material containing lithium molybdate (Li2MoO4) is applied to electronic components, which can be molded, dried at low temperatures, and optionally mixed with additives to enhance thermal protection, providing a heat-resistant barrier against high temperatures during manufacturing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If electronic components are covered with conventional thermal insulation material, then heat protection is improved, but the material requires high-temperature processing that damages the electronic component

Engineering Contradiction:
Improveheat protectionVSAvoidprocessing temperature
Core Design Contradiction:
Object-affected harmful factorsVSTemperature

Solution Approach 1:

The patent changes the processing temperature parameter from conventional high temperatures (required by traditional insulation materials) to low temperatures (below 150°C) by using a specially formulated ceramic paste containing organic vehicle that can be applied and cured at low temperatures, thus protecting heat-sensitive electronic components

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses a composite material system consisting of ceramic particles (providing thermal insulation) suspended in an organic vehicle (enabling low-temperature application), creating a paste that combines the heat protection benefits of ceramics with the low-processing-temperature advantages of organic binders

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If ceramic thermal insulation material is used, then thermal insulation performance is improved, but the material must be sintered at high temperatures which is incompatible with electronic components

Engineering Contradiction:
Improvethermal insulation performanceVSAvoidmanufacturing process compatibility
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent applies the ceramic paste to the electronic component before any high-temperature processing occurs, and the paste is then cured at low temperatures to form a protective coating, eliminating the need for subsequent high-temperature sintering that would damage the component

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces the traditional thermal sintering process (high-temperature mechanical/thermal treatment) with a low-temperature curing process using organic vehicles, substituting a harsh thermal field with a gentle chemical curing process that achieves similar structural consolidation without damaging electronic components

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
