Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external interaction devices (controllers or gloves) are paired with near-eye display devices to enhance interactive experience, then interaction capability is improved, but device weight and portability are worsened
Solution Approach 1:
The patent uses the terminal device (e.g., smartphone) as a virtual controller by copying the control functionality to the terminal device through screen direction mapping. The near-eye display device's screen direction is mapped to the terminal device's display screen, allowing users to control the near-eye device by pointing the terminal device in different directions, eliminating the need for physical controllers or gloves.
Solution Approach 2:
The terminal device serves multiple functions: it acts as both the user's communication device and the interaction controller for the near-eye display device. By making the terminal device universal for both purposes, the patent eliminates the need for dedicated external controllers, reducing overall system weight and improving portability.
2Ease of operation
If external interaction devices are paired with near-eye display devices to improve interaction capability, then control functionality is enhanced, but device cost is increased
Solution Approach 1:
The terminal device is made multi-functional by using it both as the user's communication device and as the interaction controller. This eliminates the need to manufacture and sell separate controller accessories, reducing overall system cost while maintaining enhanced control functionality.
Solution Approach 2:
Instead of requiring expensive specialized controllers, the patent copies the control interface to the user's existing terminal device, leveraging already-owned hardware to reduce additional manufacturing costs.
3Measurement precision
If traditional interaction methods with external devices are used, then control precision is achieved, but operational complexity is increased
Solution Approach 1:
The patent copies the control interface directly to the terminal device's familiar display screen, maintaining control precision through accurate direction mapping while reducing operational complexity by using the terminal device's intuitive touch interface that users already know how to operate.
Solution Approach 2:
The patent replaces complex physical interaction mechanisms (controllers, gloves, gestures) with a simplified digital interface on the terminal device screen, maintaining precision through coordinate transformation while dramatically reducing operational complexity.
