Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional double measurement method with folding rule is used, then measurement can be performed with simple equipment, but measurement time is excessive and measurement precision is reduced due to uncertainty of virtual intersection point
Solution Approach 1:
The patent combines the longitudinal and transverse measuring devices into a single integrated coordinate measuring device. The two measuring devices are merged such that they can simultaneously measure both distances from a single positioning, eliminating the need for separate double measurements and reducing time loss while maintaining precision through unified coordinate calculation.
Solution Approach 2:
The transverse measuring device is designed with pivoting capability to dynamically adjust its measuring direction by at least 90°. This dynamic adjustment allows the device to flexibly orient itself perpendicular to the longitudinal measuring direction, enabling accurate surface coordinate measurement without requiring precise manual alignment of a virtual intersection point.
2Ease of operation
If traditional double measurement method is used, then equipment complexity is low, but ease of operation is reduced due to manual alignment requirements
Solution Approach 1:
The device incorporates automatic alignment functionality where the pivoting device automatically orients the transverse measuring direction perpendicular to the longitudinal measuring direction. The computing device automatically calculates surface coordinates from the measured distances, eliminating the need for manual alignment operations and making the device self-sufficient in maintaining measurement accuracy.
Solution Approach 2:
The patent replaces manual mechanical alignment operations with electronic and computational systems. The pivoting device uses controllable mechanisms (such as motors or actuators) instead of manual adjustment, and the computing device uses electronic coordinate calculation instead of manual computation, thereby improving ease of operation despite increased device complexity.
3Measurement precision
If pivoting device with 90° adjustment is added, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The pivoting device is designed to perform multiple functions: it can adjust the transverse measuring direction by at least 90°, maintain perpendicular orientation to the longitudinal direction, and work in conjunction with the longitudinal measuring device to calculate surface coordinates. This multi-functionality justifies the increased complexity by providing comprehensive measurement capabilities in a single integrated system.
Solution Approach 2:
The computing device serves as an intermediary that processes the raw distance measurements from both measuring devices and calculates the surface coordinates. This intermediary computational layer integrates the data from the complex pivoting and longitudinal measuring mechanisms, transforming complex mechanical measurements into precise coordinate information.
4Ease of operation
If automatic alignment with leveling sensor is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The leveling sensor enables the device to automatically detect and correct its own alignment status. The device self-adjusts by using the leveling sensor to determine when the longitudinal and transverse measuring directions are properly oriented (e.g., aligned with wall edges), eliminating the need for manual alignment operations and improving ease of operation.
Solution Approach 2:
The leveling sensor provides feedback information about the device's orientation to the computing device. This feedback mechanism allows the system to monitor and adjust the alignment status automatically, creating a closed-loop control system that maintains proper orientation without requiring continuous manual intervention.
