Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rotating mechanism and interlocking mechanism are provided to control moisture absorption and release areas, then the water collecting apparatus can effectively collect moisture, but the structure becomes complex

Engineering Contradiction:
Improvemoisture collection effectivenessVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical rotating mechanism and interlocking system with a temperature-responsive polymer material that automatically changes its moisture absorption properties in response to temperature changes. The polymer compound's hydrophilicity changes with temperature, eliminating the need for mechanical movement to switch between absorption and release modes.

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

Solution Approach 2:

The patent utilizes the temperature parameter to control the hydrophilicity of the polymer compound. By changing the temperature of the moisture-absorbing material, the system automatically transitions between moisture absorption and release states without requiring mechanical actuation or complex control mechanisms.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If a heater is energized to release moisture from the polymeric moisture-absorbing material, then moisture can be released, but the structure requires an interlocking mechanism to control energization timing

Engineering Contradiction:
Improvemoisture release capabilityVSAvoidinterlocking mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent eliminates the interlocking mechanism by using a temperature-responsive polymer that automatically releases moisture when temperature increases. The polymer's inherent temperature-hydrophilicity relationship replaces the need for mechanical interlocking systems to control heater energization timing.

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

Solution Approach 2:

The moisture-absorbing material serves itself by automatically responding to temperature changes. The polymer compound inherently changes its moisture absorption characteristics based on temperature, eliminating the need for external control mechanisms to timing moisture release.

Inventive Principle:
Principle #25Self-service
