Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS signal is used for positioning, then positioning can be performed outdoors, but positioning accuracy deteriorates indoors due to structures blocking signals
Solution Approach 1:
The patent introduces an intermediary correction mechanism that mediates between the GPS positioning data and the display output. A correction UI is generated based on the difference between actual moving object speed and displayed speed, acting as a buffer to compensate for positioning errors caused by structural blockages in indoor environments.
Solution Approach 2:
The system implements feedback by continuously monitoring the difference between actual speed and displayed speed of the moving object, and dynamically adjusting the correction UI accordingly. This feedback loop ensures that positioning accuracy is maintained despite signal blockages by comparing real-time data with expected values.
2Productivity
If real-time navigation display is provided based on positioning data, then navigation guidance is available, but errors in positioning data reduce accuracy
Solution Approach 1:
The patent applies beforehand cushioning by pre-calculating and displaying navigation guidance based on corrected positioning data before errors significantly affect the user experience. The correction UI is prepared in advance to compensate for expected positioning deviations, ensuring continuous accurate guidance even when raw positioning data contains errors.
3Ease of operation
If correction UI is displayed at uniform speed, then visual guidance is smooth, but it may not match actual moving object speed variations
Solution Approach 1:
The system dynamically adjusts the correction UI display speed based on the calculated difference between actual and displayed speeds of the moving object. Rather than using fixed uniform speed, the correction mechanism adapts in real-time to match actual speed variations while maintaining visual smoothness, resolving the contradiction between operational ease and measurement precision.

AI summary
A screen display method depending upon one embodiment of the present invention comprises: a step for setting, for an indoor space, depending upon a preset rule on a movement path on which a moving object can move, node data comprising information about the location of a positioning sensor; a first display step for, on the basis of first positioning data of a first point of the moving object, generating and displaying a first correction UI moving in a first direction in which the moving object moves, the first correction UI being displayed in a corrected speed compared to the actual speed of the moving object from a first start node to a first end node; and a step for determining a succeeding display step by determining whether the moving object rotates at the first end node.
