Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If touch-based control is implemented for holographic projection devices, then interaction flexibility and accuracy are improved, but device complexity increases due to integrating touch panel recognition with holographic projection systems
Solution Approach 1:
The patent combines the touch panel recognition function with the holographic projection device into an integrated system. The touch panel is embedded within the holographic projection device, allowing touch operations to be directly recognized and processed by the device's control unit, thereby improving interaction flexibility while managing complexity through integration rather than separate components
Solution Approach 2:
The holographic projection device is designed to perform multiple functions: it can display holographic images, recognize touch operations on the integrated touch panel, generate interaction requests, and control virtual characters. This multi-functionality approach allows a single device to handle both projection and interaction control, improving versatility while consolidating system architecture
2Measurement precision
If multiple touch operation types (caress, pat) are distinguished through threshold analysis, then interaction accuracy is improved, but information processing complexity increases
Solution Approach 1:
The patent uses parameter changes in touch operations to distinguish between different interaction types. By analyzing parameters such as touch duration, touch pressure, and movement distance, the system can differentiate between caress operations (longer duration, slower movement) and pat operations (shorter duration, faster movement). This parameter-based differentiation improves recognition accuracy while using computationally simple comparison operations against predefined thresholds
Solution Approach 2:
The patent replaces complex mechanical or hardware-based touch classification systems with software-based analysis of touch parameters. The control unit processes touch information through algorithmic analysis of duration, pressure, and movement, substituting physical classification mechanisms with computational methods that are more flexible and easier to implement
