Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mobile carrier operates continuously using accumulated location information, then productivity is improved, but navigation accuracy deteriorates due to progressive errors
Solution Approach 1:
The system performs preliminary error correction by establishing a correction value before navigation errors become significant. The mobile carrier calculates a correction value based on the difference between accumulated location information and actual position, then applies this correction proactively to maintain navigation accuracy throughout continuous operation.
Solution Approach 2:
The system implements a feedback mechanism where the mobile carrier continuously monitors its own navigation accuracy by comparing accumulated location data with actual position data. Based on this feedback, the system dynamically adjusts the correction value to compensate for progressive errors, ensuring sustained navigation precision during continuous operation.
2Measurement precision
If the mobile carrier re-initializes frequently to maintain accuracy, then navigation accuracy is improved, but productivity deteriorates due to operation interruptions
Solution Approach 1:
Instead of waiting for errors to accumulate significantly and then re-initializing, the system performs preliminary correction by calculating and applying correction values during normal operation. This allows the system to maintain accuracy without interrupting the navigation task, as the correction is applied seamlessly in the background.
Solution Approach 2:
The mobile carrier performs self-correction by automatically calculating its own correction value based on the difference between accumulated and actual position data. This self-service mechanism eliminates the need for external re-initialization operations, maintaining both accuracy and operational continuity without human intervention or system interruptions.
3Productivity
If the mobile carrier uses accumulated location information for navigation, then productivity is improved, but reliability deteriorates due to progressive errors affecting operation stability
Solution Approach 1:
The system establishes a feedback loop where the mobile carrier continuously monitors the accuracy of its accumulated location information by comparing it with actual position data. Based on this feedback, the system dynamically adjusts correction values to compensate for progressive errors, ensuring reliable and stable operation throughout the navigation process without sacrificing efficiency.

AI summary
This application relates to a navigation method and a navigation apparatus. The navigation method is executed by a mobile carrier and includes: moving along a preset guide trajectory body according to obtained target location information; and determining whether a current state of the mobile carrier is out-of-position, and in response to determining that the current state of the mobile carrier is out-of-position, obtaining current initialization location information of the mobile carrier after moving to a preset initialization tag. According to embodiments of the disclosure, reliable operation of the mobile carrier is ensured by re-initializing the mobile carrier in a case that an error occurs in the mobile carrier along the preset guide trajectory body.
