Solution Overview

Problem

Users find it difficult to determine if an ionizer is mounted to an air conditioner and whether it is generating ions effectively, as existing small-sized modules are not easily recognizable and lack visibility for ion generation status.

Innovation Solution

An ionizer design that includes an ion generating unit and an ion visualizing unit mounted to the air outlet, featuring a housing with holes for ion discharge and light elements that indicate ion generation status through brightness and color changes, allowing users to visually confirm ion generation intensity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the ionizer is mounted as a small sized module to the air conditioner, then the ionizer can be installed in different types of air conditioners, but it becomes difficult for users to recognize whether the ionizer is mounted or generating ions normally

Engineering Contradiction:
Improveadaptability of ionizer installationVSAvoidvisibility of ion generation status
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent employs light elements that emit different colors or brightness levels to indicate ion generation status. When the ion generating unit produces ions, the light element changes its optical state (turns on, changes brightness, or changes color), providing visual feedback to users about the ionizer's operational status and intensity without requiring users to see the small ionizer module itself.

Inventive Principle:
Principle #32Color changes

2Volume of moving object

If the ionizer module is made small for easy installation, then it can be mounted in various air conditioner types, but the user cannot easily recognize the ionizer presence or ion generation effectiveness

Engineering Contradiction:
Improvesize of ionizer moduleVSAvoidinformation about ion generation status
Core Design Contradiction:
Volume of moving objectVSLoss of information

Solution Approach 1:

The patent introduces a light element as an intermediary indicator between the ion generating unit and the user. Instead of requiring users to directly observe the small ionizer module or its ion output, the light element serves as a visible mediator that translates the invisible ion generation process into observable visual signals, preserving all necessary information about ion generation status despite the compact size of the ionizer.

Inventive Principle:
Principle #24Intermediary (Mediator)
