Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement methods are used to create floor plans, then measurement detail can be obtained, but the process becomes time-consuming and prone to inaccuracies
Solution Approach 1:
The patent replaces manual mechanical measurement tools (tape measures, laser measures) with an automated optical-mechanical system. The mobile device combines a camera for optical capture of room features with integrated processors that automatically calculate dimensions, eliminating the need for manual measurement operations while improving both speed and accuracy.
Solution Approach 2:
The system changes the measurement parameters from direct physical measurements to indirect optical measurements. By capturing images or video of the room and using image processing algorithms to extract dimensional information, the system transforms the measurement process from time-consuming manual operations to rapid automated analysis, achieving both speed and precision.
2Productivity
If computer-aided floor plan systems are used, then measurement speed improves, but reliability and ease of use deteriorate
Solution Approach 1:
The system implements self-service by automatically performing all measurement calculations and floor plan generation without requiring expert user intervention. The mobile device autonomously captures room features, processes the visual data, calculates dimensions, and generates the floor plan, making the system reliable for ordinary users while maintaining high productivity.
Solution Approach 2:
The system incorporates feedback mechanisms where the captured images or video frames are processed to provide real-time measurement data and floor plan visualization. This feedback loop allows the system to verify measurement accuracy and adjust calculations automatically, improving reliability while maintaining fast generation speeds.
3Measurement precision
If traditional computer systems are used for floor plan creation, then accuracy can be maintained, but ease of operation and mobility are reduced
Solution Approach 1:
The system transitions from static computer-based measurement systems to a dynamic mobile measurement system. The mobile device allows users to move freely throughout the space being measured, capturing data from multiple positions and angles while maintaining dimensional accuracy through continuous tracking and coordinate transformation algorithms.
Solution Approach 2:
The mobile device serves multiple functions: it acts as a camera for capturing room features, a processor for calculating dimensions, a display for showing the floor plan, and a communication device for transmitting data. This multi-functionality consolidates what previously required separate specialized equipment into a single universal tool, improving ease of operation while maintaining precision.
4Reliability
If users remain in one location during measurement, then measurement consistency improves, but convenience and adaptability to different room layouts are reduced
Solution Approach 1:
The system adds the dimension of spatial mobility to the measurement process. Instead of constraining the user to a single location, the mobile device allows movement through three-dimensional space while using GPS-like positioning or inertial sensors to track the device's location and orientation, maintaining measurement consistency despite changes in physical position.
Solution Approach 2:
The system segments the measurement process into discrete capture points or keyframes that can be taken from different locations. By identifying and measuring key features (corners, walls, doors) at various positions and then reconstructing the complete floor plan from these segmented measurements, the system achieves both flexibility in user movement and consistency in the final result.
