Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wearable devices detect user movement to control virtual objects, then user interaction is enabled, but detection accuracy is insufficient and control smoothness is restricted
Solution Approach 1:
The patent introduces a foldable device as an intermediary tool between the user and the virtual environment. The foldable device's folding angle serves as a precise mediator that directly controls virtual object characteristics, bypassing the inaccurate movement detection of the wearable device. This intermediary mechanism enables both high precision and smooth control.
Solution Approach 2:
The patent replaces the mechanical movement detection system of the wearable device with an angular measurement system based on the foldable device's folding angle. This substitution transitions from detecting complex 3D movements to measuring a single precise angular parameter, significantly improving detection accuracy and control smoothness.
2Adaptability or versatility
If wearable devices provide virtual images with controllable virtual objects, then user interaction capability is enhanced, but detection accuracy restricts the mapping of control actions
Solution Approach 1:
The foldable device acts as an intermediary that expands control possibilities. By using the folding angle as a precise control parameter, the system can map a continuous range of angular values to diverse virtual object characteristics (position, size, angle), greatly enhancing adaptability and versatility without being limited by inaccurate movement detection.
Solution Approach 2:
The patent changes the control parameter from 3D movement vectors (with low detection accuracy) to a single angular parameter (with high measurement precision). This parameter transformation enables more accurate and versatile control action mapping, as the folding angle can precisely represent multiple degrees of freedom in a simplified manner.
