Solution Overview

Problem

Conventional liquid object dispensers require separate mechanisms for each storage tank and often dispense liquids to different locations, increasing the area needed for dispensing.

Innovation Solution

A liquid object dispenser with a transfer table that rotates to position multiple containers at a single dispensing position, allowing all liquids to be dispensed onto the same place, and includes a dispensing mechanism that presses the push button on each container to release the liquid.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple storage tanks are used to store different liquid objects, then the variety of liquid objects that can be dispensed is improved, but the device complexity increases because a separate dispensing mechanism is required for each storage tank

Engineering Contradiction:
Improvevariety of liquid objectsVSAvoiddispensing mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal dispensing mechanism that can handle multiple different liquid objects through a single interface. The container accommodating part is designed to universally accommodate different container types (bottles, tubes, jars) with a single dispensing mechanism that adapts to various container configurations, eliminating the need for separate mechanisms for each storage tank.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The transfer table is designed to be rotatable, allowing dynamic repositioning of containers between the storage position and dispensing position. This dynamic mechanism enables a single dispensing mechanism to serve multiple containers by rotating the table to bring different containers into the dispensing position sequentially.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple storage tanks are used to store different liquid objects, then the variety of liquid objects that can be dispensed is improved, but the area required for dispensing increases

Engineering Contradiction:
Improvevariety of liquid objectsVSAvoiddispensing area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent transitions from a horizontal arrangement of multiple dispensing stations to a vertical stacking configuration. Multiple containers are stacked vertically on the transfer table, and the table rotates to bring different vertical positions to the single dispensing location. This dimensional change from horizontal to vertical space utilization reduces the horizontal dispensing area while maintaining the ability to dispense multiple liquid objects.

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

3Area of stationary object

If a transfer table is introduced to move containers between storage and dispensing positions, then the area efficiency is improved, but the device complexity increases

Engineering Contradiction:
Improvedispensing areaVSAvoidtransfer mechanism
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent combines the transfer function and the positioning function into a single integrated transfer table mechanism. The rotatable table simultaneously performs the function of transferring containers from storage to dispensing positions and positioning them correctly for dispensing, merging multiple functions into one mechanism to minimize overall complexity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A liquid object dispenser includes a body, multiple containers (500), a transfer table (110) including multiple container accommodating parts accommodating the multiple containers, the transfer table being able to relatively transfer the container accommodating parts to a replacement position in the body at which the containers are replaced and to a dispensing position in the body at which the stored liquids of the containers accommodated in the container accommodating parts are dispensed, and a liquid object dispensing part configured to cause the stored liquids of the containers accommodated in the container accommodating parts at the dispensing position to be dispensed.
