Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projector is installed at different positions for different application scenarios, then the projector can be used in various settings, but it is inconvenient to mount and dismount and increases installation workload
Solution Approach 1:
The patent applies the dynamics principle by transforming the projector from a static fixed installation to a mobile robotic platform that can autonomously navigate and reposition itself. The projector is mounted on a mobile carrier with motors and sensors, enabling it to dynamically move between different locations and adapt to various application scenarios without manual installation and disassembly.
2Adaptability or versatility
If the projector is displaced and reinstalled for different positions, then different application scenarios can be supported, but the installation workload and time increase
Solution Approach 1:
The patent implements the self-service principle by equipping the projector with autonomous navigation capabilities including sensors, processors, and control systems. The projector can independently detect its environment, plan movement paths, avoid obstacles, and reposition itself to target locations without human intervention, thereby eliminating the time-consuming manual installation and disassembly process while maintaining scenario flexibility.
3Adaptability or versatility
If a new projector is purchased for different application scenarios, then the projector can be used in various settings, but the cost and installation workload increase
Solution Approach 1:
The patent applies the universality principle by designing a single projector system with mobile capabilities that can serve multiple application scenarios. The projector is equipped with sensors, processors, and navigation systems that enable it to adapt to different environments and projection requirements, replacing the need for multiple dedicated projectors and reducing both cost and installation workload.
