Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-terminal positioning methods are inefficient as they can only calculate distances between two terminals, limiting the positioning efficiency and accuracy in collaborative operations among multiple intelligent terminals.
Innovation Solution
A method where a primary terminal establishes wireless connections with secondary terminals, calculates and displays possible arrangement shapes and gestures, records user-selected configurations, and uses sensor trigger information to determine the arrangement sequence and relative positions of all terminals, enabling efficient multi-terminal positioning through a single demarcation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ultrasonic signals are transmitted between two terminals to calculate distance, then the positioning method is simple to implement, but the positioning efficiency is low because only two terminals can be positioned at a time
Solution Approach 1:
The patent merges multiple pairwise positioning operations into a single multi-terminal positioning operation. By having one terminal send ultrasonic signals to multiple other terminals simultaneously and collecting sensor trigger information from all terminals, the system determines relative positions of all terminals in one go rather than performing sequential pairwise measurements, thus improving positioning efficiency while maintaining implementation simplicity
Solution Approach 2:
The positioning method is extended from a specialized two-terminal function to a universal multi-terminal function. The same ultrasonic signal transmission and sensor trigger detection mechanism is used, but the system now handles an arbitrary number of terminals by collecting and processing sensor trigger information from multiple terminals, making the positioning method scalable and versatile
2Loss of time
If multiple terminals are positioned using sequential pairwise ultrasonic transmission, then the positioning method is easy to implement, but the time consumption increases due to multiple positioning operations
Solution Approach 1:
The system performs preliminary actions by having one terminal send ultrasonic signals to all other terminals simultaneously at the beginning, rather than waiting to perform sequential pairwise positioning. This preliminary multi-terminal signal transmission establishes the basis for determining all relative positions in parallel, significantly reducing the total time required compared to sequential operations
3Measurement precision
If sensor trigger information from multiple terminals is collected simultaneously, then the positioning accuracy is improved, but the data processing complexity increases
Solution Approach 1:
The patent introduces an intermediary processing mechanism where sensor trigger information from multiple terminals is collected and processed through a unified algorithm. The system uses the trigger time stamps and sensor trigger types as intermediate data to calculate relative positions, employing a standardized processing approach that manages data complexity while maintaining high positioning accuracy through comprehensive multi-terminal information integration
