Solution Overview

Problem

Conventional tire inflators generate excessive heat during high-power operation, which affects the lighting effect, especially in poor light conditions, and fails to efficiently dissipate heat.

Innovation Solution

The tire inflator design includes an inner housing with a chamber containing an air pump and a lighting assembly, where the lighting assembly is adjacent to the air outlet and surrounded by an outer housing for heat dissipation, utilizing a thermal conduction element and radiating ribs to transfer heat away from the device, and silicone grease to facilitate heat transfer through the air outlet, while maintaining a steady light beam.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the lighting assembly operates in a high-power state to illuminate the tire and chassis, then the illumination intensity is improved, but the temperature increases and adversely affects the lighting effect

Engineering Contradiction:
Improvelighting brightnessVSAvoidheat generation
Core Design Contradiction:
Illumination intensityVSTemperature

Solution Approach 1:

The patent extracts the lighting assembly from the inner housing and positions it adjacent to the air outlet end that extends through the outer housing. This separation allows the lighting element to be positioned where it can be illuminated by the air flow passing through the outer housing, enabling heat dissipation while maintaining lighting functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The air flow serves as an intermediary medium that performs dual functions: it cools the lighting assembly by passing over it and simultaneously provides illumination to the lighting element. The air flow acts as a heat transfer medium that carries away heat from the lighting assembly while the lighting assembly remains functional.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the lighting assembly is positioned inside the inner housing chamber, then the device structure is compact, but vibrations from the air pump affect the lighting stability

Engineering Contradiction:
Improvestructural compactnessVSAvoidlighting stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The lighting assembly is extracted from the inner housing chamber and repositioned adjacent to the air outlet end of the outer housing. This extraction removes the lighting assembly from the vibration-prone environment inside the chamber while maintaining a compact overall structure through strategic positioning near the air outlet.

Inventive Principle:
Principle #2Taking out (Extraction)

3Temperature

If the outer housing completely surrounds the inner housing for heat dissipation, then the heat dissipation efficiency is improved, but the light output is blocked

Engineering Contradiction:
Improveheat dissipation efficiencyVSAvoidlight output
Core Design Contradiction:
TemperatureVSIllumination intensity

Solution Approach 1:

The outer housing is designed with an asymmetric configuration where the air outlet end extends through the outer housing, creating an opening that allows both air flow for heat dissipation and light transmission. This asymmetric design breaks the complete enclosure to enable dual functionality of heat dissipation and light output.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The lighting assembly is positioned in a different spatial dimension adjacent to the air outlet end rather than inside the inner housing. This dimensional repositioning allows light to exit through the air outlet opening while heat dissipation occurs through the same opening, resolving the conflict between enclosure and light transmission.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
