Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If radial conductors are used in radiating panels, then the active surface can be configured, but the energy efficiency is low (around 40%) due to radial radiation not being orthogonal to the radiating surface

Engineering Contradiction:

Improveenergy efficiencyVSAvoidconductor configuration

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The patent inverts the conventional radial conductor design by using orthogonal conductors that radiate heat perpendicular to the radiating surface rather than radially outward. This inversion of the radiation direction resolves the energy efficiency problem by directing heat where it is needed while minimizing losses.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent employs curved or serpentine conductor paths within the orthogonal framework, allowing the conductors to follow optimized trajectories that maintain orthogonal radiation while distributing heat evenly across the active surface. This curvature principle enables both efficiency and uniform heat distribution.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Duration of action of moving object

If flat supporting sheets with conductive polymers are used, then the active surface size is increased, but the working life is short (3-4 years) due to molecular motion wear

Engineering Contradiction:

Improveworking lifeVSAvoidpolymer durability

Core Design Contradiction:

Duration of action of moving objectVSReliability

Solution Approach 1:

The patent replaces the mechanical/molecular motion-based heating mechanism of conductive polymers with Joule heating in carbon-based conductors. This substitution eliminates the wear caused by molecular motion while maintaining the heating function, thereby extending working life and improving reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses composite materials consisting of carbon-based conductive materials embedded in or deposited on flat supporting sheets. This composite approach combines the benefits of large active surface area with the durability of carbon materials that do not suffer from molecular motion wear.

Inventive Principle:

Principle #40Composite materials

3Area of stationary object

If conductive polymers with bare electrical connections are used, then the active surface is enlarged, but the apparatus cannot be applied to exposed structures

Engineering Contradiction:

Improveactive surfaceVSAvoidexposure suitability

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent employs composite structures where carbon-based conductors are integrated into the flat supporting sheet with enclosed or protected electrical connections. This composite design maintains the large active surface while protecting the electrical connections from environmental exposure, enabling use in building constructions.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent uses thin film encapsulation or protective coatings on the electrical connections and conductor surfaces. These thin film layers protect the exposed components from environmental factors while maintaining the flexibility and large surface area characteristics needed for building integration.

Inventive Principle:

Principle #30Flexible shells and thin films
