Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If the hollow container is emptied by making the glaze flow out or by suctioning it through pumping means, then the glaze can be removed from the container, but the operation is uncomfortable, impractical and ineffective

Engineering Contradiction:
Improveglaze removalVSAvoidemptying operation
Core Design Contradiction:
Loss of substanceVSEase of operation

Solution Approach 1:

The container is inverted to allow gravity to facilitate glaze removal. The container has a first position for glazing and a second inverted position for emptying, where the opening is at the lowest point to enable complete drainage of glaze by gravity without requiring pumping or manual manipulation.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The container is designed to be movable between two positions (glazing position and emptying position). This dynamic positioning allows the container to be tilted or inverted to facilitate complete glaze drainage, making the emptying operation simple and effective without complex pumping mechanisms.

Inventive Principle:
Principle #15Dynamics

2Reliability

If washing operation is performed on the hollow container to prevent contamination, then the container can be cleaned, but the orifices are difficult to wash effectively

Engineering Contradiction:
Improvecontamination preventionVSAvoidorifice washing
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The container is inverted during the washing phase so that the opening is at the lowest point. This allows washing fluid to effectively reach and flush through the orifices and containment chamber, ensuring complete cleaning and preventing glaze accumulation that could cause contamination.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The design replaces complex mechanical washing mechanisms with a simple gravitational flow system. By inverting the container, washing fluid naturally flows through the orifices and containment chamber under gravity, effectively cleaning all surfaces without requiring complex pumping or spraying mechanisms.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Manufacturing precision

If the hollow container is used for glazing operations, then uniform glazing can be obtained, but condensation droplets form on the outer surface and may fall onto the manufactured articles

Engineering Contradiction:
Improveglazing uniformityVSAvoidcondensation droplets
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The harmful condensation droplets are extracted or removed from the system by providing a separate drainage path. The container includes a bottom portion with a drainage opening that allows condensation droplets to drain away from the glazing surface, preventing them from falling onto the manufactured articles while maintaining the glazing function.

Inventive Principle:
Principle #2Taking out (Extraction)

4Adaptability or versatility

If color changes are made to meet different production batches, then different glaze types can be used, but the container must be emptied and washed which is time-consuming

Engineering Contradiction:
Improveglaze type changeVSAvoidemptying and washing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The container can be quickly inverted to the emptying position to rapidly drain glaze by gravity, and then inverted to the washing position for efficient cleaning. This simple positional change mechanism eliminates the need for time-consuming manual emptying and washing operations, enabling quick transitions between different glaze types.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The design replaces complex mechanical emptying and washing systems with simple gravitational flow. By inverting the container, both emptying and washing operations are accomplished through natural fluid flow under gravity, dramatically reducing the time required for these operations and enabling rapid glaze type changes.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables rapid and efficient glaze changes, effective orifice cleaning, and prevents condensation droplets from falling on articles, enhancing operational simplicity and cost-effectiveness.

Implementation Method 1

the glaze contained within the hollow container flows out by gravity intermittently arranging itself onto the manufactured articles

Methodology Applied
Scientific EffectGravity: Gravitation

Implementation Method 2

a flow of pressurized air is delivered to a lower surface of the container opposite to the direction of alignment of the orifices with one another, so as to prevent any condensation droplets that may form on the hollow container from falling onto the manufactured articles

Methodology Applied
Scientific EffectPressurized air flow: Jet
