Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex structure with multiple components (air feeder, air inducer, air mixer) is used to achieve comfortable air conditioning, then air conditioning performance is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines the functions of air feeding, air induction, and air mixing into a single integrated chamber structure. The first chamber discharges air-conditioning air directly while the second chamber induces and mixes air, eliminating the need for separate air feeder, air inducer, and air mixer components. This merging maintains comfortable air conditioning performance while significantly reducing structural complexity and cost.
Solution Approach 2:
The chamber structure performs multiple functions simultaneously: the first chamber serves as both an air discharge path and a mixing zone, while the second chamber functions as both an induction zone and a radiation surface. This multi-functionality reduces the number of dedicated components needed, simplifying the overall structure while maintaining effective air conditioning performance.
2Productivity
If the aperture ratio of air dischargers is increased to improve air distribution, then air flow efficiency is improved, but structural integrity may be compromised
Solution Approach 1:
The patent applies different aperture ratios to different air dischargers based on their specific functional requirements. The first air discharger has a first aperture ratio optimized for direct air discharge, while the second air discharger has a second aperture ratio (greater than the first) optimized for air induction and mixing. This localized optimization of aperture ratios improves overall air flow efficiency while maintaining structural integrity through targeted design.
Solution Approach 2:
The patent optimizes the aperture ratios as specific design parameters to balance air flow efficiency and structural integrity. By setting the second aperture ratio greater than the first aperture ratio, the design achieves improved air distribution and mixing efficiency while the overall chamber structure maintains sufficient strength through appropriate material selection and structural configuration.
