Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If machine learning models are used for driving safety, then driving assistance capabilities are improved, but reliability deteriorates due to failure to cover every driving situation
Solution Approach 1:
The patent introduces a formal safety model as an intermediary system that works alongside machine learning models. This formal model provides guaranteed safety bounds and constraints that the ML system must operate within, ensuring coverage of all driving situations rather than relying solely on probabilistic ML estimations.
Solution Approach 2:
The driving safety system is segmented into two distinct components: a machine learning component for probabilistic estimation and a formal safety model component for guaranteed safety bounds. This segmentation allows each component to specialize - ML handles complex pattern recognition while the formal model ensures comprehensive safety coverage.
2Device complexity
If digital plate displays are used for vehicle communication, then wireless communication requirements are reduced, but information transmission efficiency deteriorates
Solution Approach 1:
The patent transitions from traditional wireless communication (electromagnetic dimension) to visual communication through digital plate displays (optical/spatial dimension). By encoding vehicle state information in visual patterns that can be captured by cameras, the system eliminates wireless communication requirements while maintaining information transmission capability.
Solution Approach 2:
Instead of transmitting information wirelessly, the system creates visual copies of vehicle state data on the digital plate display. Other vehicles capture these visual copies using cameras and decode the information, replacing wireless transmission with optical copying and detection.
3Extent of automation
If sensors are used for vehicle state detection, then automation capabilities are improved, but measurement precision deteriorates due to noisy sensors
Solution Approach 1:
The patent introduces digital plate displays as intermediary communication devices that transmit verified vehicle state information. Instead of relying solely on noisy sensor data from other vehicles, the system uses the displaying vehicle's own sensor data (which is encoded on its digital plate) as a more reliable source, reducing measurement precision issues.

AI summary
Techniques are disclosed to realize a self-adaptive multiresolution digital plate (SAMDP) system that facilitates sharing of vehicle state information via a dynamically generated binary two-dimensional multispectral pattern. The binary 2D multispectral pattern adjusts its resolution to adapt to the visual perception process while communicating vehicle state information without relying on wireless communications (i.e. V2V, V2X, etc.). The techniques as described herein leverage the use of a multichannel spectral means that helps lower the error present in sensing and representation models used by automated driving systems.
