Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current equipment registration systems fail to accurately account for positioning errors in determining the location of equipment, leading to potential misplacement during maintenance or repair, as they do not consider the inherent errors in various positioning methods and systems used.
Innovation Solution
The equipment registration terminal includes a position determination unit, a positioning means storage unit, an error estimation unit, and an equipment registration unit that estimate and register positioning errors based on the specific positioning methods and systems used, allowing for accurate registration of equipment positions by considering the errors associated with each method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning error information is not registered during equipment position registration, then the registration process is simple and quick, but the position information cannot be used for accurate maintenance or repair operations due to unaccounted positioning errors
Solution Approach 1:
The system performs preliminary actions by automatically acquiring positioning error information from error information associated with the positioning means during the equipment registration process. This preliminary acquisition of error data allows the system to pre-process and store comprehensive position information including error margins, thereby improving position information accuracy without significantly increasing the operational complexity for end users.
Solution Approach 2:
The positioning means automatically provides its own error information to the registration terminal through self-service mechanisms. The system utilizes inherent error characteristics of the positioning means (such as GPS accuracy ratings, sensor specifications) to automatically populate error data, eliminating the need for manual error estimation or complex calibration procedures, thus resolving the contradiction between accuracy and complexity.
2Ease of operation
If positioning error information is not considered, then the equipment registration process is straightforward, but workers cannot easily locate equipment during maintenance due to potential misplacement
Solution Approach 1:
The system implements feedback by providing workers with error margin information alongside equipment position data. This feedback mechanism allows workers to understand the accuracy limitations of the registered position and adjust their search or placement operations accordingly, thereby improving ease of operation during maintenance while maintaining awareness of position accuracy limitations.
Solution Approach 2:
The system performs preliminary actions by pre-calculating and storing error margins during equipment registration. This preliminary preparation of error information enables workers to plan their maintenance operations more effectively, knowing the expected position accuracy, thus improving ease of operation without requiring complex real-time calculations or adjustments.
3Measurement precision
If various positioning methods are used without considering their specific errors, then the system is versatile and adaptable, but the position registration lacks precision due to unaccounted method-specific errors
Solution Approach 1:
The system applies local quality by associating specific error characteristics with each positioning method used. Instead of using a generic error value, the system identifies the actual positioning means employed (GPS, inertial sensors, visual markers, etc.) and retrieves or calculates the specific error information corresponding to that method, thereby improving position registration precision while maintaining flexibility in using various positioning approaches.
Solution Approach 2:
The system utilizes parameter changes by dynamically adjusting the error parameters based on the positioning method being used. The error information is not fixed but varies according to the positioning means characteristics, environmental conditions, and measurement quality, allowing the system to maintain high precision across different positioning methods while preserving adaptability.
