Solution Overview

Problem

Conventional discharge containers face issues where contents may adhere to the hand and spill when discharged, due to the saucer wobbling with respect to the internal piston, leading to inefficient discharge.

Innovation Solution

A discharge container design featuring a movable inner plate with a pushing-down portion that protrudes radially, allowing contents to be discharged without direct contact with the discharge surface, minimizing wobbling and spilling by diffusing contents radially through a diffusion chamber and locking mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the saucer is pressed downward to discharge contents, then the contents can be discharged onto the discharge surface, but the saucer wobbles with respect to the internal piston and contents may spill out

Engineering Contradiction:

Improvecontent discharge efficiencyVSAvoiddischarge stability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The device is divided into an inner plate and an exterior portion that are movable relative to each other. The inner plate can move independently to press the piston, while the exterior portion remains stable to receive contents, separating the discharge action from the receiving function to prevent wobbling and spilling.

Inventive Principle:

Principle #1Segmentation

2Productivity

If the saucer is pressed downward to discharge contents, then contents can be discharged, but contents may adhere to the hand during operation

Engineering Contradiction:

Improvecontent discharge efficiencyVSAvoidcontent adhesion to hand

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The inner plate serves as an intermediary component between the user's hand and the contents. The user operates the inner plate through the insertion hole, which indirectly actuates the piston and discharge mechanism, preventing direct contact between the hand and the contents being discharged.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If a movable inner plate with pushing-down portion is introduced to prevent adhesion and spilling, then contents can be discharged without direct contact, but the device complexity increases

Engineering Contradiction:

Improvecontent adhesion and spilling preventionVSAvoidstructure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The inner plate performs multiple functions: it acts as a pushing member to press the piston, serves as a barrier to prevent content adhesion to the hand, and controls the discharge timing. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
