Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device enters the specific region in a different direction from the registration direction, then the device can access the region from any direction, but the coordinate axes of measurement data differ from the virtual marker, making accurate detection difficult
Solution Approach 1:
The patent transforms the measurement data by changing its coordinate system parameters. Specifically, it rotates the measurement data from the device's coordinate system to the virtual marker's coordinate system using rotation matrices, enabling accurate comparison regardless of entry direction
Solution Approach 2:
The patent introduces a coordinate transformation process as an intermediary between the measurement data and virtual marker comparison. This transformation mediates the coordinate system mismatch by converting measurement data into the virtual marker's coordinate frame, allowing accurate detection across different entry directions
2Ease of operation
If the coordinate axis of measurement data is not aligned with the virtual marker coordinate axis, then the device can operate in any orientation, but accurate comparison of vector values becomes difficult
Solution Approach 1:
The patent applies coordinate transformation to change the parameter representation of measurement data. By rotating the coordinate system using rotation matrices, the measurement data is expressed in the virtual marker's coordinate frame, enabling accurate vector value comparison while maintaining device orientation freedom
Solution Approach 2:
The patent addresses the coordinate misalignment by introducing a dimensional transformation approach. It rotates the measurement data across coordinate dimensions to align with the virtual marker's coordinate system, effectively solving the orientation mismatch problem
