Solution Overview

Problem

Existing liquid replenishment containers with metal accommodation sections are inconvenient because the amount and color of the liquid cannot be visually inspected, leading to difficulties in monitoring and managing the liquid levels.

Innovation Solution

A liquid replenishment container design featuring a metal main section for reuse, with a transparent or translucent viewing section that allows users to see the liquid level and color, integrated with a pouring section and cap, preventing leakage and enhancing user convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If the liquid accommodation section is formed of metal for reuse, then the container can be reused and durability is improved, but the amount and color of the liquid cannot be seen through the metal wall

Engineering Contradiction:
Improvereuse durabilityVSAvoidliquid level and color visibility
Core Design Contradiction:
Duration of action of stationary objectVSLoss of information

Solution Approach 1:

The liquid accommodation section is divided into a metal main section for durability and a transparent/translucent viewing section for visibility. This segmentation allows each part to fulfill its specific function - the metal portion provides structural integrity and reusability, while the transparent portion enables visual inspection of liquid levels and color without compromising the overall container durability.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a transparent or translucent viewing section is added to see liquid levels, then convenience is improved, but the container structure becomes more complex

Engineering Contradiction:
Improveliquid inspection convenienceVSAvoidcontainer structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The viewing section is merged with the liquid accommodation section as an integrated structure rather than a separate attachment. This combining approach allows the transparent/translucent portion to be seamlessly integrated into the metal container body, enabling liquid visibility while maintaining structural unity and minimizing overall complexity despite the multi-material construction.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A liquid replenishment container includes a liquid accommodation section configured to accommodate a liquid, a pouring section coupled to the liquid accommodation section and having an outlet port for pouring the liquid, and a cap section mounted on the pouring section and covering the outlet port, in which the liquid accommodation section includes a main section formed of metal, and at least one of the liquid accommodation section and the pouring section includes a viewing section formed of a transparent or translucent member.
