Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional stereoscopic imaging systems are used with fixed interocular distance and convergence angle, then the system structure is simple, but the depth of field control is limited and extensive post-processing is required
Solution Approach 1:
The patent implements dynamic adjustment of interocular distance and convergence angle through motorized platforms and adjustable camera mounts. The system transitions from fixed parameters to dynamically controllable parameters, allowing real-time modification of stereoscopic imaging parameters during acquisition to eliminate post-processing requirements.
Solution Approach 2:
The platform integrates multiple functions including interocular distance adjustment, convergence angle control, and camera positioning within a single unified structure. This multi-functional design enables comprehensive control of stereoscopic parameters while maintaining structural coherence and operational efficiency.
2Loss of time
If interocular distance and convergence angle are adjusted during image acquisition, then post-processing is reduced, but the platform requires complex mechanical structures with motors and slides
Solution Approach 1:
The system performs all necessary adjustments of interocular distance and convergence angle during the image acquisition phase itself, rather than requiring subsequent post-processing. This preliminary action eliminates the need for time-consuming post-processing operations by establishing correct stereoscopic parameters before capture.
Solution Approach 2:
The patent employs motorized actuation systems to replace manual mechanical adjustment methods. Motors and controlled drive mechanisms substitute for manual positioning, enabling precise and repeatable adjustment of stereoscopic parameters while reducing operational complexity and improving consistency.
3Measurement precision
If precise interocular distance adjustment is implemented, then stereoscopic accuracy is improved, but the device requires compound crossed roller slides and motor systems
Solution Approach 1:
The system incorporates feedback mechanisms through motorized control systems that can precisely position and hold interocular distance at desired values. The motorized platforms provide controlled adjustment with the ability to maintain precise positions, enabling accurate stereoscopic measurement and imaging parameters.
