Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If AAC elements are used as lightweight building materials, then weight reduction and thermal insulation are improved, but structural connectivity and load-bearing capability deteriorate

Engineering Contradiction:

Improveweight of AAC elementsVSAvoidstructural connectivity and load-bearing capability

Core Design Contradiction:

Weight of moving objectVSStrength

Solution Approach 1:

The patent combines AAC material with embedded metal or composite webbing to create a composite structure. The webbing is integrated into the AAC element during manufacturing, creating a unified component that leverages the lightweight and insulating properties of AAC while incorporating the high strength and connectivity capabilities of metal or composite materials, thereby resolving the contradiction between weight reduction and structural strength

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The embedded webbing is strategically positioned at specific locations within the AAC element where connectivity and load-bearing capabilities are most needed, such as edges and corners. This localized reinforcement approach maintains the overall lightweight nature of the AAC element while providing targeted structural enhancement at critical points

Inventive Principle:

Principle #3Local quality

2Ease of operation

If AAC elements are used for construction, then ease of installation and thermal properties are improved, but methods for connecting and suspending to external structures deteriorate

Engineering Contradiction:

Improveease of installationVSAvoidconnectivity options for external structures

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The webbing and hardware attachments are pre-integrated into the AAC elements during the manufacturing process. This preliminary action ensures that connectivity components are properly positioned and secured before installation, eliminating the need for complex field modifications and providing multiple ready-to-use connection points for various external structure configurations

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The embedded webbing can accommodate multiple types of hardware attachments and connection methods, enabling the AAC elements to be connected to various external structures such as steel frames, concrete surfaces, and wooden structures. This multi-functionality provides versatility in connectivity options while maintaining ease of installation through a standardized embedded system

Inventive Principle:

Principle #6Universality (Multi-functionality)
