Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the analysis module directly transmits control data to the display device without reliability verification, then the system operation is simple and fast, but the image realism and quality deteriorate when sensor detection is inaccurate
Solution Approach 1:
The patent introduces an expansion module as an intermediary component between the analysis module and display device. This module receives control data from the analysis module, generates reliability information by evaluating sensor accuracy and system state, and produces modified control data based on this reliability assessment. The expansion module acts as a mediator that improves image realism through reliability verification without requiring fundamental changes to the existing analysis or display modules.
Solution Approach 2:
The system is divided into distinct functional modules: the analysis module for processing sensor data, the expansion module for reliability assessment and control data modification, and the display device for rendering. This segmentation allows the reliability verification function to be added as a separate, manageable component rather than integrating it throughout the entire system, thereby improving reliability while controlling complexity.
2Productivity
If the system displays enhancements based on unreliable sensor data, then the system operates continuously without interruptions, but the image quality and realism worsen due to geometric or radiometric inaccuracies
Solution Approach 1:
The expansion module implements a feedback mechanism where reliability information about sensor accuracy and system state is continuously evaluated and used to adjust the control data. When reliability is sufficient, enhancements are displayed with high precision; when reliability is low, the system adapts by modifying or removing enhancements. This feedback loop maintains system continuity while dynamically adjusting image precision based on actual sensor performance.
Solution Approach 2:
The system dynamically changes parameters of the displayed enhancements based on reliability information. When sensor reliability is high, full geometric and radiometric parameters are applied for precise enhancements. When reliability decreases, the system modifies these parameters or removes enhancements entirely, ensuring that image precision is maintained within acceptable bounds while the system continues to operate without interruptions.
3Speed
If the system switches between on and off states abruptly, then the system response is fast and simple, but the transition creates visible artifacts and reduces realism
Solution Approach 1:
Before completely switching enhancements off, the system performs preliminary actions by gradually reducing their visibility or integrating them into transition animations. The expansion module prepares the transition by gradually fading out enhancements or blending them with the real environment, preventing abrupt discontinuities. This preliminary action maintains visual realism during the transition while still achieving a relatively fast response.
Solution Approach 2:
The system transitions from a static on/off switching mechanism to a dynamic transition process. Instead of abrupt state changes, the expansion module implements gradual transitions with multiple intermediate states, allowing enhancements to fade in or out smoothly. This dynamic approach maintains visual realism during state changes while keeping the overall response time acceptable through optimized transition durations.
