Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional 3D recording technologies use limited angles and generalized inter-ocular distances, then device complexity is reduced, but manufacturing precision of 3D depth accuracy deteriorates
Solution Approach 1:
The patent applies dynamics by making the inter-axial distance adjustable rather than fixed. The imaging sensors can be repositioned along the bending surface to different locations, allowing the system to adapt the baseline distance dynamically based on user requirements and capture conditions, thereby achieving both depth accuracy and operational flexibility
Solution Approach 2:
The patent changes the physical parameter of inter-axial distance by allowing sensors to be positioned at different locations on the bending surface. This parameter adjustment enables the system to optimize depth capture accuracy for different scenarios while maintaining a relatively simple device structure through software-controlled sensor positioning
2Adaptability or versatility
If conventional 3D recording technologies use fixed imaging sensor positions, then device complexity is reduced, but adaptability to different users deteriorates
Solution Approach 1:
The system dynamically selects which imaging sensors to activate based on the user's inter-ocular distance and the specific capture scenario. This dynamic sensor selection allows the device to adapt to different users without requiring physical reconfiguration, achieving personalized 3D content while maintaining device simplicity
Solution Approach 2:
Multiple imaging sensors are integrated into the bendable device, each capable of serving different functions. The system can universally handle various user types and capture scenarios by selectively activating appropriate sensor combinations, making the device versatile across different use cases
3Manufacturing precision
If bendable devices use multiple imaging sensors, then 3D depth capture accuracy is improved, but device complexity increases
Solution Approach 1:
The imaging system is segmented into multiple independent sensors distributed along the bending surface. Each sensor can be independently positioned and activated, allowing the system to capture depth information from multiple angles simultaneously. This segmentation improves depth prediction accuracy while keeping each individual sensor component simple
Solution Approach 2:
The patent transitions from a fixed 2D sensor array to a 3D distributed sensor configuration along the bending surface. This spatial dimensionality change enables depth capture from multiple perspectives, significantly improving depth prediction accuracy while the flexible substrate maintains structural simplicity
