Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a measuring wheel with mechanical gear counter or electronic counter is used, then distance measurement function is achieved, but the measurement accuracy is very low and time consumption is high
Solution Approach 1:
The patent combines the measuring wheel with an angle sensor and terminal device to integrate distance measurement, direction detection, and real-time trajectory diagram generation into a single system. This merging of functions eliminates the need for separate measurement and plotting operations, thereby improving measurement accuracy while reducing time consumption.
Solution Approach 2:
The patent replaces the traditional mechanical gear counter with an electronic sensing system comprising an angle sensor and electronic counter that communicates with a terminal device. This substitution of mechanical systems with electronic/optical systems enables more precise measurement and real-time data processing, significantly improving measurement accuracy and eliminating manual plotting time.
2Productivity
If only ranging function is provided, then device structure remains simple, but work efficiency is limited
Solution Approach 1:
The patent enhances the measuring wheel with multiple functions including distance measurement, direction detection via angle sensor, real-time trajectory diagram generation on terminal device, and optional camera integration for scene marking. This multi-functionality allows a single device to perform ranging, navigation, and documentation tasks, significantly improving work efficiency despite increased device complexity.
3Productivity
If real-time trajectory diagram generation is added, then work efficiency is improved, but device complexity increases
Solution Approach 1:
The patent introduces a terminal device as an intermediary that receives data from the measuring wheel and angle sensor, then generates and displays real-time trajectory diagrams. This intermediary approach allows the core measuring device to remain relatively simple while offloading the complex diagram generation and display functions to a separate terminal device, thereby improving work efficiency without excessively increasing the complexity of the measuring device itself.
