Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the functional insert housing is provided inside the drinking bowl, then the structure is compact, but pets cannot drink falling water and can only drink water flowing along the upper surface

Engineering Contradiction:
Improvedrinking water optionsVSAvoidstructure configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into separate functional modules: a drinking bowl for storing water and a separate functional insert for water circulation. This segmentation allows pets to access both falling water from the bowl and circulating water from the insert, providing multiple drinking options without compromising structural compactness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The functional insert is positioned at a different spatial level (inside the bowl) while the bowl itself provides falling water from above. This dimensional arrangement allows pets to choose between water falling from the bowl's upper surface and water circulating within the insert, adding versatility without increasing overall device complexity.

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

2Productivity

If the functional insert has a slope with high height at the center and low height toward the edge, then water circulation is improved, but it becomes difficult for pets to drink water in the bowl or from a flat surface

Engineering Contradiction:
Improvewater circulation efficiencyVSAvoidpet accessibility
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The drinking area is segmented into two distinct zones: a sloped circulation channel within the functional insert for efficient water flow, and a separate flat drinking surface in the bowl for pet accessibility. This segmentation allows each zone to optimize its function without compromising the other.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the device have different surface characteristics: the functional insert has a sloped surface optimized for water circulation, while the drinking bowl maintains a flat surface optimized for pet drinking. This local differentiation of surface quality allows both water circulation efficiency and pet accessibility to be maximized simultaneously.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If the upper side of the drinking bowl is open, then access is easy, but water contained in the drinking bowl may be easily contaminated

Engineering Contradiction:
ImproveaccessibilityVSAvoidwater contamination
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The functional insert acts as an intermediary structure between the open bowl and the water supply system. It provides a covered circulation chamber that protects water from contamination while maintaining easy access to the bowl. The insert's design allows water to flow through it in a controlled manner, reducing exposure to contaminants.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Temperature

If heating and cooling modules are provided in the technology block, then water temperature control is improved, but the stored water in the drinking bowl cannot be cooled

Engineering Contradiction:
Improvewater temperature controlVSAvoidcooling system configuration
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The cooling function is extracted from the central technology block and implemented as a separate cooling module integrated with the functional insert. This allows the drinking bowl to be cooled independently through the insert's cooling channels, providing temperature control for stored water without requiring complex centralized cooling infrastructure.

Inventive Principle:
Principle #2Taking out (Extraction)

5Device complexity

If a water level gauge is immersed in the water in the technology block, then water level detection is simple, but the water level may not be accurately detected when used for a long time

Engineering Contradiction:
Improvedetection systemVSAvoidwater level detection accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

An external magnetic field acts as an intermediary to detect water level without direct contact with the water. The magnetic field interacts with a magnetic sensor positioned outside the water-containing chamber, allowing accurate water level detection without immersing the gauge in water, thereby maintaining both simplicity and long-term accuracy.

Inventive Principle:
Principle #24Intermediary (Mediator)
