Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If 3D measurement devices use their own independent coordinate systems for measurement, then measurement precision is maintained, but compatibility with other imaging devices is lost and coordinate system information cannot be transferred
Solution Approach 1:
The patent introduces a portable device as an intermediary that contains both a 3D measurement device and an intelligent guidance device with separate coordinate systems. This intermediary device performs coordinate transformation between the 3DM coordinate system and the IGD coordinate system, enabling data transfer and compatibility between different imaging devices while maintaining the integrity of each device's native coordinate system for precise measurement
2Ease of operation
If 3D measurement devices are made portable for easier handling, then ease of operation is improved, but coordinate system compatibility with other technologies deteriorates
Solution Approach 1:
The patent merges two previously separate devices into a single portable device: a 3D measurement device and an intelligent guidance device. This combined portable device contains both coordinate systems and includes functionality to transform between them, thereby maintaining ease of portable operation while restoring coordinate system compatibility through the integrated transformation capability
3Adaptability or versatility
If coordinate transformation is implemented between different devices, then compatibility and data transfer are improved, but device complexity increases
Solution Approach 1:
The patent places the coordinate transformation functionality within a portable device that acts as an intermediary between the stationary 3D measurement system and the intelligent guidance device. This intermediary approach centralizes the transformation logic in one device, avoiding the need to modify both end devices, thereby improving compatibility while limiting the increase in overall system complexity to a single portable unit

AI summary
A method to synchronize the position and orientation of an intelligent guidance device (IGD) 3D Coordinate System with the position and orientation of a 3D measurement device (3DM) 3D Coordinate System, in which the IGD's gravity direction measurement device and electronic compass are used explicitly. There is also described a method for maintaining the synchronization while the IGD is moving, in which the IGD's three-axis accelerometer is used explicitly. There is further described how an IGD, once its position and orientation have been synchronized to the position and orientation of a 3DM, can be used to display 3D graphics that guide the measurement process.
