Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the air flow is increased to improve dehumidification efficiency, then the heat conversion performance is improved, but the power consumption and noise increase
Solution Approach 1:
The patent changes the spatial arrangement of heat conversion modules from a vertical stack to a horizontal configuration. This dimensional change allows air to flow horizontally through multiple modules in sequence, increasing the effective heat exchange area and dehumidification efficiency without requiring increased air flow velocity or stronger forcing fans, thus avoiding higher power consumption and noise
2Volume of moving object
If the heat absorption module and heat emission module are arranged vertically, then the device structure is compact, but the flow path resistance increases and dehumidification efficiency is reduced
Solution Approach 1:
The patent transitions from vertical stacking of heat conversion modules to a horizontal arrangement. This allows air to flow horizontally through the modules with reduced resistance, as the horizontal configuration creates more favorable flow paths compared to vertical stacking, thereby improving dehumidification efficiency while maintaining a compact overall device structure through optimized module placement
3Productivity
If the heat conversion modules are arranged horizontally, then the flow path resistance is reduced and heat conversion efficiency is maximized, but the device occupies more horizontal space
Solution Approach 1:
The patent combines multiple heat conversion modules in a horizontal sequence where the heat absorption module and heat emission module work together in an integrated airflow path. This merging of functions in a coordinated horizontal arrangement maximizes heat conversion efficiency by allowing continuous heat exchange along the airflow path, while the overall footprint is managed through the modular design that can be optimized for space
