Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional cement-based construction methods are used, then construction processes are simple and familiar, but labor costs increase, productivity decreases, and environmental impact worsens

Engineering Contradiction:
Improveconstruction productivityVSAvoidconstruction process complexity
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The patent replaces conventional mechanical construction processes with automated robotic systems. Robots equipped with specialized end effectors perform cutting, drilling, fastening, and assembly operations that were traditionally done manually or with simple mechanical tools, thereby increasing productivity while managing complexity through automation

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

Solution Approach 2:

The patent changes the physical and chemical parameters of construction materials by using engineered wood products (CLT, GLT, LVL) instead of conventional cement-based materials. This substitution improves productivity and reduces environmental impact while requiring new manufacturing parameters and processes that are managed through the integrated software system

Inventive Principle:
Principle #35Parameter changes

2Extent of automation

If automated robotic production is implemented, then labor costs reduce and productivity increases, but device complexity and integration challenges increase

Engineering Contradiction:

Solution Approach 1:

The patent employs universal robotic platforms that can perform multiple construction tasks through interchangeable end effectors. The same robotic base unit can be configured for cutting, drilling, fastening, or assembly operations, reducing overall system complexity while maintaining high automation levels across different manufacturing operations

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

Solution Approach 2:

The patent introduces an integrated software system as an intermediary that coordinates between BIM models, production planning, robotic control, and quality assurance. This software layer manages the complexity of integrating multiple robotic systems and processes by providing a unified control interface and data management platform

Inventive Principle:
