Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If electronic devices provide location information about multiple external devices, then information completeness is improved, but intuitiveness of spatial distribution is worsened
Solution Approach 1:
The patent segments the closed area into multiple spaces (e.g., rooms) and groups external devices by their spatial location. This segmentation allows the system to present location information in an organized, intuitive manner while maintaining completeness, as devices are categorized by their specific spatial zones rather than presented as a single undifferentiated list.
Solution Approach 2:
The patent introduces spatial dimensionality by using depth camera modules to capture three-dimensional position information of external devices. By mapping devices to specific spaces and visualizing their spatial distribution across different dimensions (length, width, height), the system transforms flat location data into intuitive spatial representations that clearly show device positions.
2Measurement precision
If depth camera module is used to obtain distance information, then measurement precision is improved, but device complexity is worsened
Solution Approach 1:
The depth camera module serves multiple functions: it captures spatial position information, determines device location within closed areas, identifies distance to external devices, and provides data for grouping devices by space. This multi-functionality justifies the added component by eliminating the need for separate distance measurement devices.
Solution Approach 2:
The processor acts as an intermediary that receives raw depth data from the depth camera module and transforms it into meaningful location information. It processes the complex depth data to determine which space each external device occupies, thereby simplifying the overall system architecture by centralizing the interpretation function.
