Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flat image screen is used in wearable devices, then the device structure is simple, but the image cannot be adjusted in three dimensions
Solution Approach 1:
The patent transitions from a two-dimensional flat display to a three-dimensional floating image by introducing optical imaging modules that project light beams to create virtual images in space. The image display module generates light beams that are optically processed to form floating images at adjustable positions above the wearable device, enabling three-dimensional viewing angles and depth perception.
2Adaptability or versatility
If an optical imaging module is added to create floating images, then three-dimensional image capability is achieved, but the device complexity increases
Solution Approach 1:
The optical imaging modules are integrated within the wearable device housing, with the image display module positioned inside and optically connected to the imaging modules. The components are nested within each other to minimize overall device size and complexity while maintaining the floating image functionality.
Solution Approach 2:
The optical imaging modules serve multiple functions: they project light beams to create floating images, enable three-dimensional viewing, and can be integrated with gesture sensing and tactile feedback systems for interactive control. This multi-functionality reduces the need for separate dedicated components.
3Ease of operation
If gesture sensing and tactile feedback are integrated, then user interaction is enhanced, but the device complexity increases
Solution Approach 1:
The gesture sensing system automatically detects user gestures in the air space around the floating image and triggers appropriate tactile feedback responses. The system self-regulates the interaction between the user and the floating image without requiring additional control interfaces or complex programming.
Solution Approach 2:
The tactile feedback module provides immediate physical feedback to the user's gestures, creating a closed-loop interaction system. When the user performs a gesture toward the floating image, the system detects the gesture and responds with corresponding tactile feedback, enhancing the sense of interaction with the three-dimensional image.
