Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual estimation by driver or operation crew is used to determine vehicle positioning, then the positioning process is simple and quick, but the positioning accuracy is low and errors are frequent
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device that mediates between the distance metering device and the user. The mobile terminal receives distance data, retrieves corresponding dimension data from memory, calculates the operating position, and displays results. This intermediary processing layer automatically performs calculations that were previously done manually, improving positioning accuracy without requiring complex specialized equipment.
Solution Approach 2:
The system implements self-service by automatically retrieving dimension data from stored information based on the measured distance. The mobile terminal autonomously accesses pre-stored dimension data corresponding to the measured distance range and performs position calculation without requiring manual intervention or external assistance, thereby improving accuracy while maintaining simplicity.
2Measurement precision
If mobile distance metering device is used to measure distance, then the operation range estimation is improved, but the system becomes error-prone due to varying ladder dimensions and load conditions
Solution Approach 1:
The patent implements feedback by storing multiple sets of dimension data corresponding to different distance ranges and load conditions in the mobile terminal's memory. The system retrieves the appropriate dimension data based on the measured distance and automatically adjusts the position calculation accordingly. This feedback mechanism ensures that the positioning accounts for varying ladder dimensions and load conditions, improving reliability while maintaining measurement simplicity.
3Reliability
If experienced personnel perform manual estimation considering all circumstances, then the positioning reliability is improved, but the time consumption increases and valuable rescue time is lost
Solution Approach 1:
The patent applies preliminary action by pre-storing dimension data for various distance ranges and load conditions in the mobile terminal's memory before the rescue operation begins. When a distance is measured, the system immediately retrieves the corresponding pre-stored dimension data and performs automatic position calculation. This eliminates the time-consuming manual consultation of technical parameters and calculations, providing rapid and reliable positioning results during critical rescue situations.
4Measurement precision
If detailed dimension data and load information are considered for each measurement, then the positioning accuracy is improved, but the ease of operation deteriorates due to complex data requirements
Solution Approach 1:
The mobile terminal performs self-service by automatically retrieving the appropriate dimension data from its stored information based on the measured distance. The system autonomously matches the measured distance with corresponding pre-stored dimension data and performs position calculation without requiring the operator to manually select or input additional parameters. This maintains operational simplicity while ensuring accurate positioning based on detailed dimension and load considerations.
