Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a data recorder is equipped in a specific vehicle to record accident parameters, then the reconstruction of the vehicle's accident course is improved, but the ability to gather information from other parties or vehicles involved in the accident deteriorates
Solution Approach 1:
The patent combines multiple data sources by integrating the local data recorder with receiving means that capture data from other devices involved in the accident. This merging of data from multiple vehicles/parties creates a comprehensive accident reconstruction system that overcomes the limitation of single-vehicle recording.
Solution Approach 2:
The data recording system is enhanced with multi-functionality by adding receiving means capable of obtaining data through multiple transmission channels (RF, optical, acoustic). This universal approach allows the system to gather information from various sources and formats, improving both reconstruction precision and information gathering capability.
2Adaptability or versatility
If multiple transmission channels (RF, optical, acoustic) are used to receive identification data from further devices, then the flexibility and coverage of data gathering is improved, but the device complexity increases
Solution Approach 1:
The patent employs intermediary components such as antennas and receivers that can process multiple types of transmission signals. These intermediaries simplify the overall system architecture by providing a unified interface for handling diverse data transmission channels, thereby reducing the apparent complexity while maintaining versatility.
Solution Approach 2:
The system adapts to different transmission channels by changing operational parameters such as frequency, modulation type, and signal processing methods. This parameter-based approach allows the receiving means to handle multiple transmission types without requiring fundamentally different hardware for each channel, thus managing complexity.
3Extent of automation
If accident detection means are used to automatically trigger data storage, then the automation and responsiveness of accident recording is improved, but the risk of false activation increases
Solution Approach 1:
The system performs preliminary actions by continuously monitoring accident parameters and pre-configuring storage readiness. When threshold values are exceeded, the system has already prepared the storage mechanism, ensuring immediate and reliable data capture without false triggers, as the thresholds are carefully calibrated based on normal operating variations.
4Loss of information
If identification data from multiple devices is collected and stored, then the completeness of accident information is improved, but the data management and evaluation complexity increases
Solution Approach 1:
The patent segments the collected data into distinct categories such as identification data, accident parameters, and transmission metadata. This segmentation is organized in the storage means with structured formats, making it easier to manage, retrieve, and evaluate specific information without being overwhelmed by the total data volume.
