Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually input installation angles to each projector, then angle alignment can be achieved, but the adjustment process becomes complex and time-consuming
Solution Approach 1:
The projector automatically performs angle measurement and alignment operations using its built-in sensor without requiring manual user input. The system self-adjusts by comparing detected angles with reference angles and autonomously modifies projection parameters to achieve proper alignment, eliminating the need for complex manual angle input procedures
Solution Approach 2:
The patent replaces manual mechanical angle input and adjustment with an automated sensor-based detection system. The tilt sensor electronically detects the projector's installation angle, and the control unit processes this data to automatically calculate and apply alignment corrections, substituting the mechanical manual adjustment process with an electronic automated system
2Adaptability or versatility
If multiple projectors are installed at arbitrary angles, then installation flexibility is improved, but aligning the angles becomes difficult and complex
Solution Approach 1:
The system implements a feedback mechanism where the tilt sensor continuously monitors the projector's installation angle, the control unit compares the detected angle with the reference angle, and the system automatically adjusts projection parameters based on the angle difference. This closed-loop feedback ensures accurate angle alignment while maintaining installation flexibility
Solution Approach 2:
The patent creates a universal alignment system that can handle various installation scenarios (different angles, orientations, and configurations) through a single automated process. The sensor-based detection and automatic adjustment mechanism works regardless of the specific arbitrary angle chosen, making the system universally applicable to multiple installation configurations without requiring different alignment procedures
