Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If modules are arranged with free space between them to create wider rooms, then room width is improved, but natural lighting conditions deteriorate and roof construction complexity increases

Engineering Contradiction:
Improveroom widthVSAvoidnatural lighting conditions
Core Design Contradiction:
Area of stationary objectVSIllumination intensity

Solution Approach 1:

The patent applies asymmetry by making one sidewall higher than the other, creating an asymmetric roof structure. This asymmetric design allows the roof to slope downward from the higher sidewall, creating a larger opening on the higher side for improved natural lighting while maintaining the desired room width through the free space between modules.

Inventive Principle:
Principle #4Asymmetry

2Ease of manufacture

If a flat roof is used to simplify construction, then manufacturing ease is improved, but drainage capability deteriorates and watertightness becomes difficult to achieve

Engineering Contradiction:
Improveroof construction simplicityVSAvoiddrainage capability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The asymmetric sidewall heights create a naturally sloping roof surface that maintains the simplicity of flat roof construction methods while providing effective drainage. The roof slopes downward from the higher sidewall to the lower sidewall, enabling water to drain naturally without requiring complex pitched roof structures or additional drainage systems.

Inventive Principle:
Principle #4Asymmetry

3Reliability

If traditional pitched roof with ridge is used to improve drainage, then drainage capability is improved, but structural complexity and cost increase

Engineering Contradiction:
Improvedrainage capabilityVSAvoidroof structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Instead of using a traditional symmetric pitched roof with a central ridge, the patent employs asymmetric sidewall heights to create a single-sided slope. This eliminates the need for complex ridge structures, strengthening beams, and complicated roofing systems, while still achieving effective drainage through the natural slope created by the height difference.

Inventive Principle:
Principle #4Asymmetry

4Ease of manufacture

If flat roof is used to simplify construction, then manufacturing ease is improved, but energy harvesting efficiency for sunlight deteriorates

Engineering Contradiction:
Improveroof construction simplicityVSAvoidsunlight harvesting efficiency
Core Design Contradiction:
Ease of manufactureVSUse of energy by moving object

Solution Approach 1:

The asymmetric roof design creates a sloped surface that is optimally angled for sunlight harvesting. The slope angle, determined by the height difference between sidewalls, can be optimized to maximize solar energy capture throughout the day while maintaining the simplicity of flat roof construction techniques and materials.

Inventive Principle:
Principle #4Asymmetry
