Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wearable devices use movement detection to control virtual objects, then user interaction with virtual environments is enabled, but measurement precision deteriorates due to inaccurate movement detection
Solution Approach 1:
The patent introduces an external foldable device as an intermediary to provide folding angle information that serves as a more accurate control signal for virtual objects. The wearable device receives this folding angle data through communication circuits, using it as a mediator between user action and virtual object control, thereby improving measurement precision while maintaining ease of operation.
2Device complexity
If wearable devices rely on limited user movement mapping, then device complexity is reduced, but adaptability deteriorates due to restricted control actions
Solution Approach 1:
The patent makes the foldable device universal by enabling it to serve multiple functions: it acts as both a computing device and a control input device for the wearable. The folding angle information from this single device is mapped to multiple virtual object parameters including position, size, and angle, thereby increasing adaptability without proportionally increasing device complexity.
3Manufacturing precision
If wearable devices use folding angle information from external devices, then manufacturing precision of virtual object control is improved, but device complexity increases due to additional communication requirements
Solution Approach 1:
The patent merges the wearable device with the foldable device through communication circuits, combining their functionalities. The foldable device's existing folding angle sensing capability is leveraged and merged with the wearable's virtual reality rendering capability, achieving precise virtual object control while avoiding the need for complex additional sensing hardware in the wearable device.
