Position Space Identifier Grid System for Unique Coordinate Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position space identification methods, such as those using GPS, face challenges in sharing latitude and longitude information due to overlapping identifiers when different correspondence tables are used, and lack standardization in block size, leading to incompatible identifiers across users.
Innovation Solution
A method and device for dividing a position space on a celestial body into equal blocks and assigning non-overlapping unique identifiers to each unit grid, using a computer to calculate and set reference points based on accumulated errors and grid errors, ensuring that identifiers do not overlap and can be standardized across users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If latitude and longitude information is converted into unique numerical values using a correspondence table, then the information becomes shareable among users, but identifiers overlap when different correspondence tables are used by different users
Solution Approach 1:
The patent divides the position space into a grid system with standardized block sizes, segmenting the continuous geographic space into discrete, countable units. This segmentation allows identifiers to be generated systematically rather than through user-specific correspondence tables, ensuring uniqueness across all users while maintaining compatibility.
Solution Approach 2:
The patent changes the approach from converting latitude/longitude values directly into identifiers to using a grid-based coordinate system where position is determined by block indices. This parameter change from continuous coordinates to discrete grid positions eliminates the overlap problem while maintaining universal compatibility.
2Adaptability or versatility
If block size is not standardized in correspondence tables, then users can customize their position space division, but identifiers become incompatible across users with different block sizes
Solution Approach 1:
The patent establishes a universal grid system with standardized block sizes that serves all users simultaneously. This universal framework allows any user to reference positions using the same identifier system, ensuring compatibility while still allowing customization of which positions are relevant to their specific applications.
3Measurement precision
If latitude and longitude information is shared using user-specific correspondence tables, then each user can accurately represent their position space, but the system complexity increases due to multiple different tables
Solution Approach 1:
The patent merges multiple user-specific correspondence tables into a single universal grid system. By combining all position space representations into one standardized framework, the system reduces complexity while maintaining the precision needed for accurate position representation across all users.

AI summary
The present invention provides a method for imparting unique identifiers that do not overlap each other to individual position spaces in the case of latitude and longitude information or even in the case of height information also included in addition thereto. A longitude line passing through the coordinate origin is divided by the length of one side of a unit grid, and a latitude value inside unit grids is calculated. An accumulated error is calculated in a case where latitude values inside the unit grids are accumulated for one round in a longitude line direction of a celestial body, and an error per unit grid is calculated based on the calculated accumulated error. The number of unit grids included in one block in the longitude line direction is specified so that a reference error per block is equal to or smaller than one thousandth of the accumulated error, and thus a reference latitude is set. A reference longitude is set by the same calculation process for each latitude line that is determined based on the set reference latitude, reference points are specified sequentially from the coordinate origin based on the set reference latitude and reference longitude, and a unique identifier is imparted to each unit grid located in a block with the reference points set as its vertices.
