Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional VR glasses are used with basic display functionality only, then the device structure remains simple, but user experience is poor due to lack of head-turning assistance
Solution Approach 1:
The head-turning assisting device is nested within the strap structure of the VR glasses. The strap serves as both the fastening component and the housing for the assisting device, which contains multiple voice coil motors and associated components. This nested arrangement allows the complex head-turning assistance system to be integrated into the existing simple strap structure, improving user experience without significantly increasing overall device complexity
Solution Approach 2:
The strap is designed to serve multiple functions: it fastens the VR glasses to the user's head, houses the head-turning assisting device, and provides structural support. The head-turning assisting device itself performs multiple functions by using different combinations of voice coil motors to assist head turning in various directions and provide haptic feedback, thereby improving ease of operation through multi-functionality
2Ease of operation
If four flat voice coil motors are added to assist head-turning, then head-turning assistance is improved, but device complexity increases
Solution Approach 1:
The head-turning assisting device is segmented into four independent flat voice coil motors, each responsible for a specific direction or aspect of head turning. This segmentation allows for modular control where each motor can be independently activated based on the required head-turning direction, simplifying the control logic compared to a single complex motor system while still providing comprehensive head-turning assistance
Solution Approach 2:
The master controller receives feedback about the display image and the user's head position, then automatically adjusts the activation and strength of each voice coil motor to provide appropriate head-turning assistance. This feedback mechanism allows the system to manage the complexity of coordinating four motors automatically, improving ease of operation without requiring complex manual control
