Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If heating equipment is used to heat water in the water storage cavity, then water temperature suitable for human body is achieved, but heat dissipates faster over time especially in cold seasons

Engineering Contradiction:
Improvewater temperatureVSAvoidheat loss
Core Design Contradiction:
TemperatureVSLoss of energy

Solution Approach 1:

A thermal insulation structure comprising insulating material is introduced as an intermediary layer between the water storage cavity liner and the frame. This intermediary layer reduces direct thermal contact between the water and the external environment, thereby minimizing heat loss while maintaining the heated water temperature for extended periods

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The thermal insulation structure changes the thermal conductivity parameter of the pool system by introducing materials with low thermal conductivity between the water storage cavity and the external environment. This parameter change effectively reduces the rate of heat transfer from the warm water to the colder external surroundings

Inventive Principle:
Principle #35Parameter changes

2Duration of action of stationary object

If thermal insulation structure is added between liner and frame, then heat preservation is prolonged, but device complexity increases

Engineering Contradiction:
Improveheat preservation durationVSAvoidpool structure complexity
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The thermal insulation structure is segmented into multiple insulating panels or sections that can be independently installed between the liner and frame segments. This segmentation allows for easier handling, installation, and maintenance while achieving comprehensive thermal insulation coverage, thereby reducing the practical complexity despite adding insulation functionality

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The thermal insulation structure is nested within the existing pool structure by positioning it between the liner and the frame, utilizing the existing structural space. This nesting approach allows the insulation layer to be integrated into the existing design without requiring additional external structural elements, thereby minimizing the increase in overall device complexity

Inventive Principle:
Principle #7Nested doll (Nesting)
