Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are installed in the air conditioner indoor unit, then detection of environmental parameters is enabled, but airflow cannot pass through the sensor smoothly resulting in inaccurate detection data
Solution Approach 1:
The patent introduces an air guide hole as an intermediary structure between the airflow path and the sensor. This air guide hole serves as a mediator that channels the airflow smoothly toward the sensor, preventing direct turbulent flow from disrupting the sensor while still delivering adequate air for accurate detection. The air guide hole acts as a buffer zone that reconciles the conflict between maintaining smooth sensor operation and providing sufficient airflow.
Solution Approach 2:
The patent modifies the spatial arrangement by creating a three-dimensional air guide structure with specific geometric features (air guide holes at angles, varying depths). This dimensional approach allows the airflow to be redirected through multiple spatial paths before reaching the sensor, transforming the direct linear airflow-sensor interaction into a multi-dimensional flow pattern that reduces turbulence while maintaining detection accuracy.
2Volume of moving object
If the internal structure of the air conditioner is maintained for compactness, then device size is reduced, but airflow cannot pass through the sensor smoothly
Solution Approach 1:
The air guide hole structure is nested within the existing indoor unit housing, utilizing the available internal space efficiently. The air guide holes are integrated into the housing structure rather than adding external components, allowing the guidance function to be embedded within the compact design. This nesting approach enables improved sensor airflow without increasing the overall device volume.
Solution Approach 2:
The patent applies local structural modifications only in the specific region where the sensor is located, rather than redesigning the entire indoor unit. The air guide holes are positioned locally around the sensor area, providing targeted airflow management precisely where needed while leaving the rest of the compact structure unchanged. This localized approach maintains overall device compactness while solving the specific sensor airflow problem.
