Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the air flow system only provides basic air volume and temperature selection, then the system complexity is low and ease of operation is maintained, but the adaptability to different user preferences and conditions is insufficient
Solution Approach 1:
The patent introduces multiple discharging modes (first mode with constant gradient, second mode with gradually increased gradient, third mode with gradually decreased gradient) that dynamically change the air volume increase width. This allows the system to adapt to different user preferences and environmental conditions while maintaining a relatively simple control interface, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The system changes the parameter of air volume increase width according to different discharging modes. By varying this parameter (constant, gradually increased, or gradually decreased gradient), the system achieves diverse air flow control patterns without adding complex hardware, thus improving adaptability while controlling complexity.
2Manufacturing precision
If multiple discharging modes with different air volume increase gradients are added, then the adaptability and control precision are improved, but the device complexity increases
Solution Approach 1:
The control system dynamically adjusts the air volume increase width based on the selected discharging mode. The first mode provides constant gradient for predictable control, the second mode provides gradually increased gradient for rapid response, and the third mode provides gradually decreased gradient for smooth transitions. This dynamic adjustment achieves high control precision without requiring complex hardware modifications.
Solution Approach 2:
The air flow controller is designed to handle multiple discharging modes within a single device, making it multi-functional. The controller can switch between different air volume increase gradients (constant, gradually increased, gradually decreased) based on user selection, achieving high control precision while avoiding the need for multiple separate control systems.
3Adaptability or versatility
If the system provides only automatic and manual modes, then the ease of operation is maintained, but the versatility in controlling air flow form and strength is limited
Solution Approach 1:
The patent segments the air flow control into distinct discharging modes (first mode, second mode, third mode), each with specific air volume increase characteristics. This segmentation allows users to select from predefined patterns that are easy to operate, while still providing versatile control over air flow form and strength through the different gradient patterns.
Solution Approach 2:
The system changes the air volume increase width parameter according to different discharging modes, providing versatility in controlling air flow characteristics. Users can easily select from modes with constant, gradually increased, or gradually decreased gradients, achieving versatile control without complicating the operation interface.
