Solution Overview

Problem

Robots face heat accumulation issues due to sealed inner spaces, leading to potential operational disruptions, and existing heat dissipation methods involving gas tubes increase costs and complicate wiring designs.

Innovation Solution

A heat dissipating system utilizing a gas supply device that outputs high-pressure gas into the robot's inner space, with a valve mechanism that releases the gas when open, preventing external air ingress and allowing adjustable flow to enhance cooling efficiency, particularly near high-heat components like motors and axles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If gas tube with holes is disposed in the inner space for heat dissipation, then the elements can be cooled, but the cost increases and the wiring design becomes more complicated

Engineering Contradiction:
Improvecooling efficiencyVSAvoidwiring complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent extracts the gas tube component from the robot's internal structure and replaces it with the robot's outer skin itself. The outer skin is designed with heat-dissipating structures that directly serve as gas passage channels, eliminating the need for separate gas tubes and their associated wiring connections.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the functions of the outer skin (protective covering) and the gas passage channels (heat dissipation pathway) into a single integrated structure. The outer skin simultaneously serves as both the protective envelope and the conduit for heat-dissipating gas flow.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If the inner space is sealed for robot operation, then the robot structure is protected, but heat accumulates and affects operation

Engineering Contradiction:
Improvestructural protectionVSAvoidheat accumulation
Core Design Contradiction:
ReliabilityVSTemperature

Solution Approach 1:

The patent employs the outer skin as a flexible shell that incorporates heat-dissipating structures and gas passage channels. This flexible shell design allows the sealed protective structure to simultaneously function as a heat dissipation system through integrated airflow pathways.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent utilizes pneumatic principles by introducing gas flow through the outer skin's heat-dissipating structures. The gas flow creates convection currents that actively remove heat from the sealed inner space while maintaining the protective seal.

Inventive Principle:
Principle #29Pneumatics and hydraulics

3Temperature

If high-pressure gas is released through the valve for cooling, then the inner space is cooled, but external air may flow in and reduce IP rating

Engineering Contradiction:
Improvecooling effectVSAvoidair ingress
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent employs a dynamically controllable valve that responds to pressure differential signals. When internal pressure exceeds external pressure during heat dissipation, the valve opens to release gas. When pressures equalize or internal pressure drops, the valve automatically closes, dynamically adapting to pressure conditions to prevent air ingress.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The valve system incorporates feedback control where the valve operation is determined by the pressure differential between internal and external environments. The system monitors pressure conditions and adjusts valve state accordingly, opening when internal pressure is higher and closing when pressures are equalized, thereby preventing external air contamination.

Inventive Principle:
Principle #23Feedback
