Solution Overview

Problem

Handling devices, such as industrial robots, face challenges in heat dissipation due to insulation from foam coverings, leading to increased internal temperatures and potential component damage, while also risking contamination in clean environments due to air leaks and dust ingress.

Innovation Solution

A heat dissipation system with perforated elements of varying size and airtight structures, utilizing suction or overpressure devices connected to the handling device's structure, allows for efficient air flow and cooling without increasing internal space or costs, and maintains air purity in clean environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a foam cover is used to protect the handling device, then collision protection is improved, but heat dissipation deteriorates

Engineering Contradiction:
Improvecollision protectionVSAvoidinternal temperature
Core Design Contradiction:
StrengthVSTemperature

Solution Approach 1:

The foam cover is designed with a porous structure that allows heat to pass through while maintaining mechanical protection. The pores enable thermal energy to conduct through the foam material, preventing heat buildup inside the handling device while preserving the collision protection function.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The foam cover has varying density or pore size in different regions to optimize both protection and heat dissipation. Areas requiring higher structural strength have denser foam, while areas prioritizing heat dissipation have more porous structures, creating a spatially differentiated solution.

Inventive Principle:
Principle #3Local quality

2Temperature

If air leaks are present in the handling device, then heat dissipation is improved, but contamination risk increases

Engineering Contradiction:
Improveheat dissipationVSAvoidcontamination
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

A dedicated air extraction system is implemented that actively removes heated air from the handling device interior through controlled openings. This separates the heat dissipation function from uncontrolled leaks, allowing heat to be expelled through designed pathways that minimize contamination risk.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A filtration system acts as an intermediary between the device interior and external environment. The filter allows heat-carrying air to pass through while trapping dust and contaminants, enabling heat dissipation without direct exposure to the contaminated external atmosphere.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If the structure is made airtight to prevent contamination, then air purity is improved, but heat dissipation deteriorates

Engineering Contradiction:
Improveair purityVSAvoidheat accumulation
Core Design Contradiction:
Object-affected harmful factorsVSTemperature

Solution Approach 1:

The airtight structure incorporates continuous or periodically activated ventilation channels that maintain a steady flow of air for heat removal. This ensures continuous heat dissipation while preserving the overall airtight seal, preventing contamination during operation.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The airtight structure is segmented into multiple sealed compartments with dedicated thermal management pathways. Each segment maintains its own pressure balance and air flow characteristics, allowing localized heat dissipation without compromising the overall air purity of the system.

Inventive Principle:
Principle #1Segmentation
