Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fixed antenna designs are used in traditional detection systems, then device simplicity is maintained, but detection sensitivity and specificity deteriorate due to inability to optimize for different targets
Solution Approach 1:
The detection system is segmented into a base unit and interchangeable antenna modules. Each antenna is designed as a separate, optimized component for specific material types (e.g., liquid containers, pills, powders). This allows the system to achieve high detection sensitivity for each target type while maintaining overall system versatility through modular architecture.
Solution Approach 2:
The base detection unit is designed as a universal platform that can accommodate multiple specialized antennas through standardized connectors. The control system provides universal material identification capabilities by selecting and configuring appropriate antennas based on the target material, enabling one device to perform multiple detection functions.
2Reliability
If fixed antenna designs are used, then device complexity is reduced, but signal-to-noise ratio deteriorates leading to unreliable detection results
Solution Approach 1:
By segmenting the antenna system into specialized modules, each antenna can be optimized for its specific function without increasing the complexity of the base unit. The segmentation allows complex, highly optimized antennas to be developed independently and swapped as needed.
Solution Approach 2:
The system uses standardized connector designs and modular antenna interfaces that can be replicated across different antenna types. This standardization reduces the complexity of integrating multiple specialized antennas while maintaining high detection reliability through consistent, optimized connections.
3Measurement precision
If multiple specialized devices are used for different materials, then detection accuracy for each material is optimized, but device portability and ease of operation deteriorate
Solution Approach 1:
The detection system is designed as a universal platform with interchangeable antennas, allowing a single portable device to perform multiple material detection functions. Users can select the appropriate antenna for the target material, achieving specialized detection accuracy without carrying multiple separate devices.
Solution Approach 2:
The system dynamically adapts to different detection needs by allowing users to swap antennas based on the target material. This dynamic configuration enables the device to maintain high detection accuracy for various materials while preserving portability and ease of operation through a single integrated unit.
4Measurement precision
If traditional detection systems are upgraded to improve capabilities, then detection performance is enhanced, but cost and modification complexity increase significantly
Solution Approach 1:
The system separates the expensive, specialized components (antennas) from the base unit, allowing incremental upgrades by replacing only the antenna module rather than redesigning the entire system. This segmentation reduces upgrade costs and simplifies manufacturing by allowing independent optimization of antenna components.
Solution Approach 2:
The universal base unit with standardized connectors allows the system to accommodate multiple specialized antennas without requiring custom modifications for each application. This reduces overall system cost and simplifies manufacturing by using a common platform for diverse detection needs.
