Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operations are used to prepare two-dimensional floorplans, then compliance with government regulations can be achieved, but the process is time-consuming and prone to errors
Solution Approach 1:
The patent replaces manual mechanical operations with an automated mobile mapping device that captures images and automatically processes them to generate floorplans. The device uses camera imaging and automated recognition algorithms to identify walls, doors, windows, and furniture, eliminating the need for manual measurement and drawing while significantly reducing errors and time consumption.
Solution Approach 2:
The mobile mapping device performs self-service by automatically capturing spatial data, recognizing objects and structures through image processing, and generating floorplans without requiring manual intervention. The system autonomously navigates the space, captures multiple images, processes them through algorithms, and produces the final floorplan output independently.
2Adaptability or versatility
If manual methods are used to create floorplans, then initial creation can be completed, but updates when changes occur in the floor environment are difficult
Solution Approach 1:
The patent implements a dynamic floorplan system where the mobile mapping device can re-scan the environment at any time to detect changes. The system automatically compares new scans with existing floorplans, identifies modifications such as moved furniture or changed wall configurations, and updates the digital floorplan accordingly, making the system adaptable to environmental changes.
Solution Approach 2:
The system performs preliminary action by continuously capturing and storing spatial data in the mobile device's memory during normal operation. This pre-captured data serves as a baseline for quick comparison when updates are needed, allowing the system to rapidly detect changes without starting from scratch.
3Reliability
If conventional systems are used to prepare floorplans, then basic mapping can be achieved, but the process is prone to errors due to compliance regulations
Solution Approach 1:
The patent implements feedback mechanisms where the mobile mapping device captures images, processes them through recognition algorithms, and automatically verifies compliance with government regulations. The system provides feedback on detected features, compares them against regulatory requirements, and allows for verification and correction before finalizing the floorplan, thereby improving both compliance accuracy and overall precision.
