Solution Overview

Problem

Existing medium processing apparatuses face challenges in easily attaching and detaching a water supply tank, especially in narrow spaces, which affects the efficiency and convenience of liquid application processes.

Innovation Solution

A medium processing apparatus with a liquid applier, first and second liquid storage tanks, and a locking mechanism that allows for easy attachment and detachment of the second liquid storage tank, ensuring continuous liquid supply to the first tank.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a water supply tank is made detachable for easy refilling, then ease of operation is improved, but reliability of liquid supply may deteriorate due to potential attachment/detachment failures

Engineering Contradiction:
Improveease of attachment and detachmentVSAvoidreliability of liquid supply
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The liquid storage system is divided into a main body tank and a detachable water supply tank. This segmentation allows the water supply tank to be easily removed for refilling while maintaining a reliable connection during operation through the locking mechanism, thus resolving the contradiction between ease of operation and supply reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A locking mechanism acts as an intermediary between the water supply tank and the main body. This intermediary component ensures reliable attachment and detachment operations, preventing accidental disconnection during liquid supply while allowing easy user operation, thereby addressing both reliability and ease of operation requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the water supply tank is made detachable, then ease of operation is improved, but device complexity increases due to additional locking mechanism

Engineering Contradiction:
Improveease of attachment and detachmentVSAvoidcomplexity of locking mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

By segmenting the liquid storage into detachable components, the system achieves ease of operation through simple attachment and detachment actions, while the locking mechanism adds minimal complexity compared to the overall system structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking mechanism is designed to automatically engage and lock when the water supply tank is inserted into the main body, eliminating the need for complex manual locking operations. This self-locking feature reduces operational complexity while maintaining ease of use.

Inventive Principle:
Principle #25Self-service

3Productivity

If liquid storage capacity is increased, then productivity is improved, but loss of time for refilling may increase

Engineering Contradiction:
Improveproductivity of liquid applicationVSAvoidtime for refilling
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The liquid storage system is segmented into a main body tank and a detachable water supply tank. This allows the water supply tank to be quickly removed and replaced when empty, minimizing refilling time while maintaining sufficient liquid storage capacity for extended operation periods.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The water supply tank can be pre-filled with liquid before attachment. This preliminary preparation allows for rapid exchange of tanks during operation, reducing refilling time interruptions while ensuring continuous liquid supply to maintain productivity.

Inventive Principle:
Principle #10Preliminary action

AI summary

A medium processing apparatus includes a liquid applier to apply liquid to a part of a medium to perform liquid application, a first liquid storage to store the liquid used for the liquid application of the liquid applier, a second liquid storage to store the liquid to be supplied to the first liquid storage, and a liquid supplier to perform a liquid supply operation to supply the liquid from the second liquid storage to the first liquid storage. The second liquid storage includes a liquid storage tray connected to the liquid supplier, a liquid storage tank to store the liquid and is attachable to and detachable from the liquid storage tray, and a locking mechanism to restrict a position of the liquid storage tank attached to the liquid storage tray.
