Solution Overview

Problem

Conventional sterilizers for drinking containers are large in size, making them inconvenient to use.

Innovation Solution

A portable sterilizer with two disinfection chambers, one for the lid and one for the bottle body, allowing disinfection from both upper and lower directions, optimizing the internal space utilization and reducing the overall volume.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional sterilizer is designed with a large sterilization chamber to accommodate drinking containers, then the sterilization function is effective, but the device becomes large in size and inconvenient to use

Engineering Contradiction:
Improvesterilization effectivenessVSAvoidsterilizer size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The sterilizer is divided into two separate disinfection chambers: an upper lid disinfection chamber and a lower bottle body disinfection chamber. This segmentation allows each chamber to be optimized for its specific function while reducing the overall volume compared to a single large chamber design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent utilizes vertical space by arranging the two disinfection chambers one above the other within the receiving channel. This dimensional arrangement maximizes space utilization and reduces the horizontal footprint of the device, making it more portable.

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

2Device complexity

If a single disinfection chamber is used to sterilize both lid and bottle body, then the device structure is simple, but the internal space cannot be fully utilized and the sterilization efficiency is reduced

Engineering Contradiction:
Improvestructure simplicityVSAvoidsterilization efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The disinfection function is segmented into two independent chambers with separate disinfection components. The upper chamber handles lid sterilization while the lower chamber handles bottle body sterilization, allowing simultaneous operation and improving overall sterilization efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Both disinfection chambers can operate simultaneously and continuously, with the upper disinfection component disinfecteding the lid while the lower disinfection component disinfecteds the bottle body, eliminating idle time and maximizing sterilization productivity.

Inventive Principle:
Principle #20Continuity of useful action
