Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional ozone converter design is used, then the device structure is simple, but the airflow measurement capability is insufficient and maintenance efficiency is low
Solution Approach 1:
The patent combines the ozone converter core with integrated airflow measurement capabilities (pressure sensors, temperature sensors) and flow sensor assemblies into a single unified device. This merging allows the device to perform both ozone conversion and precise airflow measurement functions simultaneously, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The ozone converter is designed as a multi-functional device that simultaneously performs ozone decomposition, airflow measurement, temperature monitoring, and flow rate calculation. The universal design integrates multiple sensing functions into one device, improving measurement capabilities without proportionally increasing structural complexity.
2Ease of repair
If the ozone converter core is permanently installed, then the structural integrity is high, but the maintenance efficiency and core replacement speed are low
Solution Approach 1:
The ozone converter is divided into separable components: a housing and a removable core element. The core can be independently removed and replaced through the opening in the housing, allowing rapid maintenance without replacing the entire device. This segmentation directly improves repair ease while keeping the coupling mechanism relatively simple.
Solution Approach 2:
The coupling between the core and housing is designed to be dynamically changeable - securely attached during operation for structural integrity, but easily separable during maintenance. The removable design allows the core to transition between fixed and mobile states, improving maintenance efficiency without significantly complicating the overall structure.
3Measurement precision
If the ozone converter occupies more space for comprehensive sensing, then the measurement accuracy is improved, but the packaging volume in aircraft is increased
Solution Approach 1:
The sensing components (pressure sensors, temperature sensors, flow sensor assembly) are nested within the housing and core structure. The measurement elements are integrated into the existing volumetric space rather than adding external bulk, allowing comprehensive sensing capabilities within a compact footprint suitable for aircraft packaging constraints.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement of sensing elements within the core and housing. Pressure sensors are positioned at different locations and orientations, and the flow sensor assembly is integrated in a way that maximizes measurement capability within the available volume, effectively using dimensional optimization to reduce packaging requirements.
