Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration of projector network IP address and remote controller ID is performed for each unit, then individual customization is achieved, but installation time and labor cost increase significantly
Solution Approach 1:
The system performs preliminary configuration by automatically assigning network IP addresses and remote controller IDs to projectors before the installation process begins. This pre-configuration eliminates the need for manual setup during installation, resolving the contradiction between individual customization and installation time.
Solution Approach 2:
The projector system automatically configures itself with unique network parameters and identification codes without requiring manual intervention. This self-service capability maintains individual customization while dramatically reducing installation time and labor requirements.
2Adaptability or versatility
If human visual identification and experience-based adjustment is used for projector alignment, then flexibility in handling different installation scenarios is achieved, but labor cost and installation complexity increase
Solution Approach 1:
The system replaces manual visual identification and experience-based adjustment with an automated image processing system that uses computer vision algorithms to detect projector positions and calculate alignment parameters. This substitution maintains adaptability to different installation scenarios while reducing labor cost and simplifying the installation process.
Solution Approach 2:
An automated calculation system serves as an intermediary between the physical projector installation and the final alignment configuration. This intermediary automatically processes installation parameters and generates setting values, bridging the gap between physical placement and optimal configuration without requiring manual expertise.
3Manufacturing precision
If projectors are repositioned and reinstalled to correct installation defects, then installation accuracy is improved, but time consumption and labor cost increase
Solution Approach 1:
The system performs preliminary detection of installation parameters and calculates correction values before final configuration is applied. This preliminary action allows installation defects to be corrected through parameter adjustment rather than physical repositioning, improving accuracy while avoiding time-consuming reinstallation.
Solution Approach 2:
Instead of physically repositioning projectors to correct installation defects, the system changes the parameter values (such as projection offset, rotation angle, and scaling factors) to compensate for installation errors. This parameter-based correction achieves the same effect as repositioning but without the time and labor costs.
4Ease of operation
If projectors are turned on to project images before lens adjustments, then real-time visualization is achieved, but energy consumption increases during setup
Solution Approach 1:
The system replaces the need for physical image projection with virtual simulation that calculates and displays expected projection results based on installation parameters. This substitution eliminates energy consumption during the setup phase while maintaining the ability to visualize and adjust settings before actual projection begins.
