Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional 2D touch displays are used to manipulate dimensioning results, then the system structure remains simple, but the ease of operation deteriorates due to difficulty in decoupling height/width from depth
Solution Approach 1:
The patent transitions from 2D display manipulation to 3D augmented reality visualization, allowing users to interact with dimensioning results in three dimensions. This enables intuitive decoupling of height/width from depth by providing spatial separation of dimensional information, directly resolving the operational difficulty described in the contradiction.
2Measurement precision
If 2D display is used for wireframe adjustment, then device complexity is low, but measurement precision deteriorates due to misalignment between intended and actual adjustments
Solution Approach 1:
By implementing 3D augmented reality visualization instead of 2D display, the system provides accurate spatial representation of wireframes and their relationship to the scanned object. This eliminates the misalignment problem between intended and actual adjustments by allowing direct 3D manipulation with visual feedback.
Solution Approach 2:
The augmented reality interface provides real-time visual feedback showing the scanned object with overlaid wireframe graphics. This feedback loop allows users to immediately see the effect of their adjustments and make precise corrections, thereby improving measurement precision.
3Reliability
If traditional dimensioning interface is used, then ease of operation is maintained, but reliability deteriorates due to inability to verify correct scanning
Solution Approach 1:
The system provides visual feedback by overlaying wireframe graphics representing the scanned object onto the real-time camera view. This allows users to verify whether the 3D scanner has captured the object correctly by comparing the wireframe with the actual object appearance, thereby improving reliability.
Solution Approach 2:
The augmented reality interface creates a visual copy of the scanned object through wireframe graphics that can be overlaid on the real object. This copy allows users to verify the accuracy of the scan without needing to physically measure the object, maintaining ease of operation while improving reliability.
