Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If membrane plates are made large and suspended without adequate support, then coverage area is increased, but thermal stresses and mechanical forces reduce durability

Engineering Contradiction:
Improvecoverage areaVSAvoiddurability
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The membrane plate is divided into multiple smaller segments or panels that are independently supported. This segmentation reduces the span between support points, decreasing mechanical forces and thermal stresses on each segment while maintaining overall coverage area. The patent shows membrane plates divided into multiple sections with intermediate support structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The membrane plate suspension system is designed to be flexible and adaptable to thermal expansion and mechanical forces. The patent employs flexible connections and adjustable support mechanisms that allow the membrane to dynamically respond to thermal stresses without compromising durability or coverage.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If insulation cover units are designed to be identical in installation, then manufacturing is simplified, but adaptation to varying temperature differences and installation widths is reduced

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidadaptation to temperature differences and installation widths
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent employs standardized membrane plate units with uniform dimensions and properties for ease of manufacture. These identical units can be systematically arranged in different configurations to adapt to varying installation widths and temperature differences, achieving versatility through modular assembly rather than custom-designed components.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The standardized membrane plate units are designed to be universally applicable across different installation scenarios. By using identical modular units that can be arranged in various patterns and supported by adjustable structures, the system achieves adaptability to different widths and temperature conditions while maintaining manufacturing simplicity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of manufacture

If membrane plate thickness is uniform throughout installation, then manufacturing is easier, but optimal insulation performance across varied temperature levels is reduced

Engineering Contradiction:
Improvemanufacturing easeVSAvoidinsulation performance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent employs membrane plates with varying thicknesses in different regions of the installation. Areas with higher temperature differences or longer thermal loading durations utilize thicker membrane plates for optimal insulation, while cooler areas use thinner plates. This localized variation in thickness optimizes insulation performance across the entire installation while the modular approach keeps manufacturing manageable.

Inventive Principle:
Principle #3Local quality
