Solution Overview

Problem

Existing dispensing technologies for viscous materials face challenges in precise delivery, environmental sensitivity, and efficient refilling, leading to material degradation and waste due to inadequate handling and storage conditions.

Innovation Solution

A precision dispenser with a linear guide and actuating device allows one-handed operation, featuring a bidirectional linear motion, a sealing cap for environmental protection, and a dispensing tip for controlled material delivery, ensuring uniform coating and consistent application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual dispensing is used, then ease of operation is improved, but manufacturing precision deteriorates

Engineering Contradiction:
Improveease of operationVSAvoidmanufacturing precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The dispenser allows the user to operate it with one hand while the device itself maintains precise dispensing through its mechanical design, including the linear guide and actuating mechanism that ensure consistent material delivery without requiring two-handed operation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent modifies the dispensing parameters by controlling the linear motion of the actuating device, which regulates the amount and speed of material delivery through the outlet opening, thereby achieving precise dispensing while maintaining ease of operation

Inventive Principle:
Principle #35Parameter changes

2Productivity

If rapid refilling is implemented, then productivity is improved, but reliability deteriorates

Engineering Contradiction:
ImproveproductivityVSAvoidreliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The dispenser design allows for preliminary preparation of refilling operations by maintaining a ready-to-use container system that can be quickly exchanged, reducing downtime while ensuring proper sealing and connection are established before refilling begins

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The linear guide and actuating mechanism are designed to maintain continuous operation during refilling, allowing the dispensing action to proceed without interruption or degradation of material flow consistency, thereby ensuring both productivity and reliability

Inventive Principle:
Principle #20Continuity of useful action

3Device complexity

If environmental control is not implemented, then device complexity is reduced, but loss of substance increases

Engineering Contradiction:
Improvedevice complexityVSAvoidloss of substance
Core Design Contradiction:
Device complexityVSLoss of substance

Solution Approach 1:

The container is designed with a sealing cap that provides environmental protection for the viscous material, preventing desiccation and contamination while maintaining a relatively simple device structure without requiring complex environmental control systems

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The sealing cap creates a protected environment for the viscous material in the container, isolating it from adverse environmental conditions such as humidity and oxidation, thereby preventing material degradation and waste without adding significant device complexity

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)
