Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If measuring devices are located outside the measuring cell as in conventional setups, then interference with the system under test is reduced, but transport complexity and setup time increase significantly
Solution Approach 1:
The patent combines the measuring devices with the measuring cell by integrating them into the same housing structure. The measuring cell (1) and measuring devices (70) are merged into a single integrated unit, eliminating the need for separate transport and manual positioning of equipment outside the cell. This resolves the contradiction by maintaining measurement accuracy through integrated shielding while dramatically simplifying transport and setup procedures.
Solution Approach 2:
The patent employs a nested arrangement where the measuring cell is divided into multiple compartments or areas. The system under test is placed in a first area, while measuring devices are positioned in a second area within the same housing. This nested structure allows measuring devices to be physically integrated with the measuring cell (simplifying transport) while maintaining spatial separation (reducing interference).
2Measurement precision
If measuring devices are manually positioned outside the measuring cell, then measurement accuracy is maintained, but time consumption and costs increase
Solution Approach 1:
By merging the measuring devices with the measuring cell into a single integrated unit, the patent eliminates the time-consuming manual positioning process. The integrated design ensures that measurement accuracy is maintained through built-in shielding and proper spatial arrangement, while setup time is dramatically reduced as the entire system can be deployed as one unit.
Solution Approach 2:
The measuring devices are pre-positioned and integrated with the measuring cell during manufacturing. This preliminary action ensures that when the system is deployed, no manual positioning is required - the measuring devices are already in their optimal positions for accurate measurement, thus eliminating setup time while maintaining measurement precision.
3Adaptability or versatility
If a mobile measuring cell is used with separate measuring instruments, then mobility is achieved, but the system is not suitable as a complete mobile laboratory
Solution Approach 1:
The patent merges the measuring cell with complete measuring devices to create a self-contained mobile laboratory. The integrated unit includes all necessary components (measuring cell, measuring devices, shielding, and support structures) as a single deployable system, achieving both mobility and system completeness that eliminates the need for separate equipment transport and setup.
Solution Approach 2:
The integrated measuring cell is designed as a universal platform that can perform multiple measurement functions. By combining various measuring devices within a single mobile unit, the system achieves multi-functionality, serving as a complete mobile laboratory capable of handling different measurement tasks without requiring additional external equipment.
4Object-affected harmful factors
If conventional measuring cells are used, then shielding is provided, but only very specific types of measurements can be carried out
Solution Approach 1:
The patent integrates multiple types of measuring devices within a single measuring cell, creating a universal measurement platform. This multi-functional design allows the same shielded cell to perform various measurement tasks (different measurement types) while maintaining effective shielding, thus resolving the contradiction between shielding effectiveness and measurement versatility.
Solution Approach 2:
The measuring devices are arranged in a flexible, adaptable configuration within the measuring cell. The system can be dynamically reconfigured or adapted to perform different measurement types while maintaining the protective shielding environment, allowing the same physical cell to serve multiple measurement purposes effectively.
