Solution Overview

Problem

Existing heating element cooling mechanisms are prone to damage due to direct transmission of vibration from the heating element to the cooling section.

Innovation Solution

A heating element cooling mechanism that supports the heating element and cooling section with a support section, uses a heat transfer member to prevent direct contact, and incorporates a buffer member to absorb vibration, ensuring the heating element and cooling section are not in direct contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the heating element and cooling section are in direct contact to improve heat transfer efficiency, then heat exchange performance is improved, but the cooling section is damaged by vibration transmission from the heating element

Engineering Contradiction:
Improveheat exchange efficiencyVSAvoidcooling section durability
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

A buffer member is introduced as an intermediary component between the heating element and cooling section. This buffer member serves dual functions: it transmits heat from the heating element to the cooling section while simultaneously absorbing vibrations to prevent damage to the cooling section. The buffer member acts as a mediator that reconciles the conflicting requirements of direct contact for heat transfer and isolation for vibration protection.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The buffer member is pre-installed between the heating element and cooling section to provide beforehand cushioning against vibrations. By positioning the vibration-absorbing buffer member in advance, the system prepares for vibration transmission before it occurs, thereby protecting the cooling section from potential damage while maintaining thermal contact.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Reliability

If vibration isolation measures are added to protect the cooling section, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvecooling section protectionVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The buffer member is designed to perform multiple functions simultaneously: it provides vibration isolation to protect the cooling section while also serving as a heat transfer medium. This multi-functionality eliminates the need for separate vibration isolation components, thereby improving reliability without significantly increasing device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The vibration isolation function and heat transfer function are merged into a single buffer member component. Instead of using separate elements for vibration damping and thermal conduction, the invention combines these functions into one integrated component, simplifying the overall structure while achieving both protection and efficiency goals.

Inventive Principle:
Principle #5Merging (Combining)
