Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the flow of air is increased to improve dehumidification efficiency, then dehumidification performance is improved, but flow path resistance increases and power consumption increases
Solution Approach 1:
The patent transitions from a vertical arrangement (heat absorption part above heat emission part) to a horizontal arrangement where the heat emission part is positioned at the lower side of the heat absorption part in the air flow direction. This dimensional change optimizes the air flow path, reducing resistance while maintaining effective heat exchange, thereby improving dehumidification efficiency without increasing power consumption
2Productivity
If the flow of air is increased to improve dehumidification efficiency, then dehumidification performance is improved, but noise increases
Solution Approach 1:
By repositioning the heat emission part to the lower side of the heat absorption part in the air flow direction, the patent creates a more efficient horizontal heat exchange path. This reduces the required air flow velocity to achieve the same dehumidification effect, thereby lowering noise generation from high-velocity air movement
3Volume of moving object
If the heat absorption part is arranged above the heat emission part in a vertical direction, then the structure is compact, but flow path resistance increases and heat conversion efficiency decreases
Solution Approach 1:
The patent modifies the vertical arrangement by positioning the heat emission part at the lower side of the heat absorption part in the air flow direction, creating an optimized horizontal heat exchange configuration. This maintains structural compactness while significantly reducing flow path resistance and improving heat conversion efficiency through more effective thermal coupling between the modules
