Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current methods for measuring and adjusting PAPI light beam characteristics are used, then measurement can be performed, but the measurement process is complex and does not effectively measure luminous intensity
Solution Approach 1:
The patent combines multiple measurement functions (luminous intensity measurement, beam characteristic analysis, and alignment verification) into a single integrated mobile measurement device. This merging eliminates the need for separate complex measurement systems while achieving effective luminous intensity measurement that was previously unavailable in prior art methods.
Solution Approach 2:
The patent replaces complex mechanical measurement systems with a mobile device equipped with photodetectors and processing electronics. This substitution simplifies the measurement apparatus while enabling precise luminous intensity measurements and automated beam characteristic analysis, resolving the contradiction between measurement capability and device complexity.
2Productivity
If a single orientable camera with zoom and inertial platform is used, then rapid and accurate measurement of light beam characteristics is enabled, but the device requires motorized movement systems and complex data processing
Solution Approach 1:
The patent employs a mobile measurement device with motorized positioning systems that can dynamically adjust the camera's position and orientation. The inertial platform provides real-time orientation data, enabling rapid acquisition of beam characteristics from multiple angles. This dynamic capability accelerates measurement productivity while the integrated control system manages the complexity of coordinated movements.
Solution Approach 2:
The patent incorporates feedback mechanisms where the camera captures beam characteristics, the inertial platform provides orientation data, and the processing system analyzes this information to determine alignment status. This closed-loop feedback enables rapid automated measurement and reduces the need for manual intervention, improving productivity despite the increased device complexity.
