Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users virtually move corners of operational zones to shape safety planes, then flexibility in defining safety zones is improved, but device complexity and processing requirements increase
Solution Approach 1:
The safety plane adjustment is segmented into discrete corner points that can be independently adjusted. Each corner point becomes a separate control element that can be moved individually, transforming a complex continuous adjustment problem into manageable discrete steps.
Solution Approach 2:
The patent introduces a visual overlay dimension where virtual safety planes are superimposed on the real-world view through the AR device camera. This additional visual layer allows users to perceive and adjust safety zones in 3D space while maintaining simplified 2D interaction through touch gestures on the display surface.
2Adaptability or versatility
If users virtually move corners of operational zones, then adaptability in shaping safety planes is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces complex mechanical manipulation of virtual objects with simple touch gestures on a display surface. Users interact with safety plane corners through 2D touch movements that automatically translate to 3D spatial adjustments, eliminating the need for complex mechanical controls or manual coordinate input.
Solution Approach 2:
The AR device display acts as an intermediary between the user and the robot controller. Touch gestures on the display surface serve as intermediate commands that are automatically processed and translated into safety plane adjustments, simplifying the interaction chain from user input to system response.
3Measurement precision
If complex virtual manipulation is required to adjust safety planes, then precision in defining zones is improved, but ease of operation worsens
Solution Approach 1:
The AR device provides real-time visual feedback by overlaying the virtual safety planes on the camera view of the real-world environment. Users can immediately see how their touch gestures affect the safety zone positioning, allowing for precise adjustments through iterative visual confirmation without requiring complex coordinate calculations.
Solution Approach 2:
The patent maps 3D safety plane positioning to 2D touch gestures on the display. This dimensional reduction allows users to control complex spatial parameters through simple surface touches, maintaining precision while dramatically improving ease of operation.
