Solution Overview

Problem

Existing headlight moisture removal methods, such as using fans or vacuuming, are inefficient and costly, as they require additional energy or increase the unit price of headlights, and do not effectively prevent moisture condensation and performance degradation.

Innovation Solution

A moisture-removing apparatus using electrolysis with a moisture decomposition module comprising electrodes coated with a dielectric material and a moisture-absorbing layer, which decomposes moisture through electric discharge and absorbs condensed moisture to prevent condensation inside the headlight.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a fan is installed inside the headlight to forcibly circulate air, then moisture circulation is improved, but energy consumption increases

Engineering Contradiction:
Improvemoisture circulation efficiencyVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent replaces the mechanical fan system with an electrochemical electrolysis system. Instead of using a motor-driven fan to circulate air, the invention uses electrodes that generate electric discharge to decompose moisture molecules directly, eliminating the need for mechanical moving parts and reducing energy consumption while maintaining moisture removal effectiveness

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

2Reliability

If the inside of the headlight is vacuumized to prevent moisture, then moisture condensation is prevented, but the unit price and repair cost increase

Engineering Contradiction:
Improvemoisture preventionVSAvoidunit price
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent implements a self-service moisture removal system where the headlight contains its own moisture decomposition capability through integrated electrodes. The system automatically decomposes moisture that enters the headlight housing through electric discharge, eliminating the need for expensive vacuum sealing processes and specialized manufacturing procedures while maintaining reliable moisture prevention

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention changes the approach from preventing moisture entry (vacuum sealing) to active moisture decomposition (electrolysis). By applying electrical parameters (electric discharge between electrodes) to chemically decompose water molecules, the system achieves moisture prevention without requiring vacuum-level sealing or expensive specialized manufacturing

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the entire headlight is replaced when the light source needs replacement, then moisture damage is prevented, but repair cost increases

Engineering Contradiction:
Improvecorrosion preventionVSAvoidrepair cost
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The patent makes the headlight housing self-protecting against moisture corrosion through integrated electrolysis electrodes. This active moisture decomposition system ensures that even when the headlight is opened for light source replacement, any introduced moisture is automatically decomposed, allowing standard replacement procedures without requiring complete unit replacement and reducing repair costs

Inventive Principle:
Principle #25Self-service
