Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional graphical design logic means (mathematical constraints, formal constraints, combination constraints) are used in schematic design, then design optimization principle of 'less specifications, more combinations' is achieved, but the design cannot effectively convey standardization concepts to actual construction, leading to disparities between design and construction
Solution Approach 1:
The patent introduces BIM (Building Information Model) as an intermediary between schematic design and actual construction. BIM serves as a digital mediator that carries standardization concepts through structured data models, enabling precise transmission of design intentions to construction processes. The BIM model acts as a bridge that reconciles the abstract design standards with concrete construction requirements, eliminating the disparity between design phase and construction phase.
Solution Approach 2:
The patent replaces traditional graphical design logic (manual constraint-based approach) with digital information management methods. Instead of relying on paper-based drawings and manual calculations, the system uses digital BIM models that automatically manage design parameters, standardization rules, and construction information. This substitution of mechanical/graphical systems with digital systems enables precise conveyance of standardization concepts throughout the entire design-construction lifecycle.
2Reliability
If BIM technology is used in detailed design for information management, then collision errors and omissions are reduced, but the design thinking and process differ from schematic design, making it difficult to achieve unified standardization
Solution Approach 1:
The patent makes BIM a universal tool that serves multiple functions across different design phases. The same BIM platform is used for schematic design, detailed design, and construction documentation, enabling consistent standardization concepts to be maintained throughout. By making BIM multi-functional, the system eliminates the need for separate tools for different design stages, thereby reducing overall process complexity while maintaining high information accuracy.
Solution Approach 2:
The patent applies preliminary action by establishing standardized BIM templates and parameter sets before the design process begins. These pre-configured templates contain built-in standardization rules and checklists that guide designers through each phase, ensuring consistency without requiring complex real-time decision-making. The preliminary setup of design frameworks reduces the complexity of managing standardization across different design stages.
3Adaptability or versatility
If architects use individual design habits and experiences in schematic design, then design creativity is maintained, but the depth of designs is difficult to quantify and unify, hampering efficient detailed and optimization design
Solution Approach 1:
The patent uses visual differentiation through BIM parameter coloring and highlighting to make design depth measurable and quantifiable. Different design parameters, standardization levels, and optimization potentials are visually marked within the BIM model, allowing architects to quickly identify areas that need further development. This visual encoding system transforms abstract design depth into visible, measurable characteristics while preserving creative freedom through flexible parameter configuration.
