Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a handheld controller is used to interact with virtual scenes, then the virtual reality apparatus can achieve basic control functionality, but the operational accuracy is low and the control becomes complex
Solution Approach 1:
The patent extracts the control function from the handheld controller and integrates it directly into the virtual reality apparatus body. Sensors (accelerometer, gyroscope, magnetometer) are built into the VR device itself, allowing head movements and body actions to directly control virtual scenes without requiring external handheld controllers, thus simplifying operation while maintaining or improving accuracy
Solution Approach 2:
The virtual reality apparatus is designed to perform multiple functions: it serves as both the display device and the control device. The same apparatus that provides immersive visual experience also contains sensors and processing units that detect user actions and translate them into control signals, eliminating the need for separate control equipment
2Adaptability or versatility
If a handheld controller is connected to the virtual reality apparatus, then control functionality is achieved, but the operational complexity increases and user experience degrades
Solution Approach 1:
The patent merges the control system with the virtual reality apparatus into a single integrated unit. The sensors, signal converters, and control processing units are all incorporated within the VR device body, creating a unified system that reduces the number of separate components and simplifies the overall control architecture
Solution Approach 2:
The virtual reality apparatus serves itself by containing all necessary control components within its own structure. The device detects user actions through integrated sensors, processes the signals through built-in converters, and executes control commands without requiring external handheld controllers or additional control equipment
