Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of guide elements is used, then air flow direction can be changed, but the adjustment process becomes time-consuming and complex
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated drive mechanism. The drive element automatically moves the guide element between positions, eliminating the need for manual intervention and reducing adjustment complexity while maintaining air flow direction change capability.
Solution Approach 2:
The guide element is designed to be movable rather than fixed, allowing it to change position dynamically. This dynamic configuration enables the system to adapt air flow direction as needed while the automated drive mechanism simplifies the operation of this dynamic adjustment.
2Adaptability or versatility
If multiple independent arc-shaped guides are installed, then air flow direction can be adjusted, but the design and manufacture become complex and expensive
Solution Approach 1:
The guide structure is divided into modular components (guide element and drive element) that can be manufactured separately and assembled. This segmentation simplifies the design and manufacture process while maintaining the capability for air flow direction control.
Solution Approach 2:
The single guide element serves multiple functions: it deflects air flow in different directions, its position can be adjusted automatically, and it works with the drive mechanism to provide versatile control. This multi-functionality reduces the need for multiple separate components, simplifying overall design and manufacture.
3Manufacturing precision
If guide elements are manually adjusted during installation, then air flow direction can be aligned, but qualified personnel are required and subsequent changes are complex
Solution Approach 1:
The automated drive mechanism replaces manual adjustment, maintaining precise alignment capability while making the system accessible to non-specialist personnel. The drive element automatically positions the guide element to achieve the desired air flow direction.
Solution Approach 2:
The system performs its own adjustment through the automated drive mechanism, eliminating the need for external manual intervention. This self-service capability maintains precision while improving ease of operation, as the system can be adjusted by anyone operating the drive mechanism.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient air distribution with vertical flow for heating to reach lower areas and horizontal flow for cooling, reducing temperature stratification and drafts, while allowing non-specialist personnel to adjust the air direction, ensuring thorough mixing and effective induction.
Implementation Method 1
the at least one guide element is arranged in the air distribution chamber on the air outlet surface in the first position or is arranged at a small distance from the air outlet surface, and in the second position is arranged in the transition piece or rests against walls of the housing
Implementation Method 2
the housing is provided with walls which are arranged at an acute angle to the air outlet surface
Implementation Method 3
part of the housing is a transition piece which is arranged between the walls and the nozzle, wherein the cross-sectional area of the transition piece, measured perpendicular to the flow direction, is larger than the cross-sectional area of the nozzle
