Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional tape measure or ruler is used to measure distances from multiple reference points, then measurement can be performed, but the process becomes laborious, complex, and time-consuming
Solution Approach 1:
The patent combines multiple distance measurement functions into a single handheld device that can simultaneously measure distances from multiple reference points. The device integrates multiple sensors and processing capabilities to perform what would traditionally require multiple separate measurement operations, thereby increasing productivity while managing device complexity through integration.
Solution Approach 2:
The patent replaces traditional mechanical tape measures and rulers with an electronic device that uses sensors (such as time-of-flight sensors, ultrasonic sensors, or laser sensors) to measure distances electronically. This substitution eliminates the need for physical extension and manual reading, significantly reducing the time and complexity of measurement operations.
2Measurement precision
If traditional measurement tools are used to mark target points with accuracy, then measurement precision can be achieved, but the process is time-consuming and complex
Solution Approach 1:
The device performs preliminary calculations and determines the exact target point location before the actual marking action. By pre-calculating the intersection point coordinates based on distances from multiple reference points, the system enables rapid and accurate marking without time-consuming on-site calculations or multiple measurement adjustments.
Solution Approach 2:
The patent replaces manual measurement and marking processes with electronic sensing and automated or assisted marking. The electronic sensors provide precise distance data that is processed to identify the exact target point, eliminating the need for repeated manual measurements and adjustments, thereby reducing time while maintaining or improving accuracy.
3Measurement precision
If multiple reference points are measured sequentially, then accurate target location can be determined, but the process becomes more complex and time-consuming
Solution Approach 1:
The patent merges multiple distance measurement functions into a single integrated device that can simultaneously or rapidly sequence measurements from multiple reference points. The device incorporates multiple sensors and a centralized processing system that handles all measurements and calculations in a unified manner, reducing the complexity that would arise from coordinating multiple separate measurement operations.
Solution Approach 2:
The handheld device is designed with universal functionality to measure distances from multiple reference points and perform various measurement tasks (distance measurement, angle measurement, target point determination) within a single device. This multi-functionality eliminates the need for multiple specialized tools and reduces the overall complexity of performing comprehensive measurements.
4Productivity
If manual measurement and marking is performed, then device complexity is low, but productivity is reduced and time is lost
Solution Approach 1:
The patent replaces simple manual mechanical tools with an electronic handheld device that uses sensors (time-of-flight, ultrasonic, laser) and electronic processing to perform measurements and calculations. This substitution dramatically improves productivity by eliminating manual extension, reading, and calculation steps, while the device complexity is managed through integrated design and miniaturized components.
