Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UWB wireless communication is used to enable wireless image transmission, then wireless communication capability is improved, but signal coverage and link quality deteriorate
Solution Approach 1:
The patent divides the medical treatment room into multiple zones by deploying multiple host wire adapters (at least three) at different locations. Each adapter serves as an independent reception node, ensuring that at least one adapter maintains reliable wireless connection with the detector regardless of its position or NLOS conditions. This segmentation of the reception system resolves the contradiction by maintaining wireless communication capability while improving signal coverage through distributed reception points.
Solution Approach 2:
The patent introduces a controller as an intermediary that receives position information from multiple host wire adapters and determines the detector's location. This intermediary coordinates the multiple adapters, enabling them to work together as a unified system that overcomes individual adapter limitations in NLOS environments, thereby improving overall signal coverage while maintaining wireless communication.
2Adaptability or versatility
If multiple wireless detectors are deployed to improve detection coverage, then detection capability is improved, but detector location and management difficulty increases
Solution Approach 1:
The patent implements a feedback mechanism where wireless detectors periodically broadcast beacon messages containing their position information. Multiple host wire adapters receive these beacons and report to the controller, which determines detector locations and provides feedback for system management. This automated feedback loop resolves the contradiction by enabling comprehensive detection coverage while simplifying management through automatic position tracking and identification.
Solution Approach 2:
The wireless detectors perform self-identification and self-positioning by automatically broadcasting beacon messages with their unique identifiers and location data. The system automatically determines detector positions without requiring manual configuration or user intervention, thereby improving detection coverage while reducing management complexity through autonomous operation.
3Ease of operation
If detector position is unknown to simplify system operation, then ease of operation is improved, but image transmission reliability deteriorates
Solution Approach 1:
The wireless detector automatically provides its own position information through periodic beacon messages that include location data. The host wire adapters and controller automatically receive and process this information without requiring user input. This self-service approach resolves the contradiction by maintaining ease of operation (no manual position configuration needed) while ensuring image transmission reliability through automatic position awareness.
Solution Approach 2:
The system continuously receives feedback from beacon messages containing detector position information. The controller uses this feedback to determine detector locations and manage image transmission accordingly. This automated feedback mechanism resolves the contradiction by keeping the system easy to operate (automatic position tracking) while ensuring reliable image transmission (accurate position awareness).
