Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two-dimensional drawing tools are used for layout design, then the design process is simple and manual, but the detection range and visual field of security devices cannot be fully reflected, leading to blind spots
Solution Approach 1:
The patent transitions from two-dimensional drawing tools to three-dimensional layout software, enabling accurate representation of the detection ranges and visual fields of security devices. This dimensional change allows virtual placement and adjustment of devices to eliminate blind spots while maintaining design simplicity through automated generation of two-dimensional construction drawings.
2Adaptability or versatility
If manual counting and documentation is performed, then the process is flexible, but it costs a lot of manpower and is difficult to guarantee consistency and quality
Solution Approach 1:
The system automatically counts security devices, generates material lists, switch wiring tables, and other documentation without manual intervention. The three-dimensional layout software self-calculates detection coverage and visual fields, eliminating the need for manual counting while ensuring consistent and high-quality output documents.
Solution Approach 2:
The patent replaces manual documentation processes with automated computer-generated documents. The system automatically extracts device information from the three-dimensional layout, generates material lists, wiring tables, and construction drawings, thereby reducing manpower consumption while maintaining or improving document quality and consistency.
3Ease of manufacture
If two-dimensional drawings are used for construction guidance, then the construction process is straightforward, but blind regions are discovered only after construction, leading to rework
Solution Approach 1:
The patent performs preliminary detection of blind spots during the design phase using three-dimensional layout software. By virtually placing security devices and calculating their detection ranges and visual fields before construction, the system identifies and corrects potential blind spots in advance, ensuring accurate device placement during construction without requiring rework.
