Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
3D measurement devices have internal coordinate systems that are not compatible with other technologies, making it difficult to transfer measurements without losing information, and there is a need to synchronize their orientation with Intelligent Guidance Devices (IGDs) for effective measurement guidance.
Innovation Solution
The method involves using a gravity direction measurement device and electronic compass to define a common coordinate system for both the 3D measurement device and the IGD, applying rigid transformations to synchronize their orientations, allowing the IGD to display 3D graphics that guide the measurement process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable 3D measurement device is made with its own coordinate system for ease of handling, then portability and ease of operation are improved, but compatibility with other technologies deteriorates
Solution Approach 1:
The patent introduces an intermediary coordinate transformation system that acts as a bridge between the portable 3D measurement device's local coordinate system and the global reference frame. By defining transformation matrices that map measurements from the device's coordinate system to a standardized reference frame, the system enables compatibility with other technologies while preserving the portability and ease of operation of the handheld device.
2Adaptability or versatility
If coordinate systems of different devices are used without synchronization, then device independence and flexibility are improved, but information loss during transfer occurs
Solution Approach 1:
The patent applies preliminary coordinate system alignment and transformation before data transfer occurs. By pre-establishing the relationship between different coordinate systems through transformation matrices and calibration procedures, the system preserves all measurement information during transfer, eliminating information loss while maintaining device independence.
3Ease of operation
If intelligent guidance devices display 3D graphics without synchronized coordinate systems, then guidance functionality is provided, but spatial accuracy and measurement precision deteriorate
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors and adjusts coordinate system alignment between the measurement device and guidance device. By using transformation matrices that are updated based on real-time position and orientation data, the system maintains spatial accuracy in displayed 3D graphics while providing effective measurement guidance functionality.
