Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement tools are used to gather stage dimension data, then measurement accuracy can be achieved, but the process becomes extremely time-consuming and labor-intensive
Solution Approach 1:
The patent replaces manual mechanical measurement tools (measuring tapes, rulers) with an automated optical measurement system consisting of a scanner, camera, and structured light projector. This substitution eliminates the need for manual measurement operations while maintaining measurement accuracy through sophisticated image processing and 3D reconstruction algorithms.
Solution Approach 2:
The patent creates a digital 3D copy of the stage by projecting structured light patterns onto the stage surface and capturing the reflected light with a camera. The scanner processes these images to generate an accurate digital replica of the stage geometry, which can be stored and manipulated without requiring repeated physical measurements.
2Loss of information
If comprehensive stage dimension data is collected manually, then complete spatial information is obtained, but the data becomes difficult to visualize and interpret
Solution Approach 1:
The patent transforms 2D stage dimension data into a 3D digital model that can be viewed and manipulated from any angle. The structured light scanning system captures spatial information in three dimensions, allowing users to rotate, zoom, and inspect the stage model interactively, making the data intuitive to understand and work with.
Solution Approach 2:
The patent creates a virtual digital copy of the physical stage that preserves all spatial dimensions and geometric features. This digital replica can be manipulated on computer screens, allowing for easy visualization, measurement, and analysis without requiring physical presence on the stage or interpretation of complex spreadsheets.
3Device complexity
If existing lighting fixtures are used without customization, then system complexity is reduced, but the ability to achieve precise lighting control may be limited
Solution Approach 1:
The patent makes existing lighting fixtures multi-functional by integrating them with the 3D scanning and modeling system. The same fixtures that illuminate the stage are used to project structured light patterns for scanning, and then controlled through the digital 3D model for precise positioning and intensity control, eliminating the need for separate specialized equipment.
Solution Approach 2:
The patent implements a feedback loop where the 3D scanner captures the actual position and state of lighting fixtures, compares them with the desired positions in the digital model, and automatically adjusts the fixtures to achieve precise alignment. This closed-loop control system ensures accurate lighting placement without manual intervention.
