Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If parallel adjustment design of blades is adopted, then the structure is simple, but the venting is uneven due to inconsistent gap sizes and angles
Solution Approach 1:
The vent system is divided into multiple independent air guide plates (at least three) that are distributed in a circular array, each capable of independent rotation. This segmentation allows each plate to be adjusted individually to achieve uniform venting, resolving the contradiction between simple structure and uniform venting performance.
Solution Approach 2:
Multiple air guide plates are combined with a synchronous rotation mechanism that uses a single rotary disc with guide grooves to control all plates simultaneously. This merging of control functions ensures that all plates rotate by the same angle, achieving uniform venting while maintaining operational simplicity.
2Manufacturing precision
If multiple air dampers are added for uniform venting, then venting uniformity is improved, but device complexity increases
Solution Approach 1:
Multiple air dampers are merged into a single synchronous rotation mechanism. The rotary disc with radially distributed guide grooves controls all air guide plates simultaneously through a single rotary knob, reducing control complexity while maintaining venting uniformity through equiangular rotation of all dampers.
Solution Approach 2:
The guide grooves on the rotary disc are designed to be equidistant from the center, ensuring that all air guide plates rotate by the same angle when the rotary knob is turned. This equipotential design achieves uniform venting without requiring complex individual control mechanisms for each damper.
3Ease of operation
If air guide plates are rotated to adjust wind direction, then wind direction control is improved, but friction and wear increase
Solution Approach 1:
The air guide plates are designed to rotate along guide grooves rather than sliding against flat surfaces. This groove-based rotation reduces contact area and friction, allowing smooth adjustment of wind direction while minimizing wear and energy loss.

AI summary
The present invention relates to the technical field of automobile fittings, and discloses a foldable and flexible vent for an air conditioner, comprising a base, a hose and an air guide cylinder, wherein one end of the base communicates with the vent for the air conditioner, and the other end communicates with the hose; the air guide cylinder is arranged at one end of the hose away from the base; the vent further comprises an air damper and a rotating mechanism. The plurality of air dampers are distributed in a circular array in the air guide cylinder with the axis thereof as the center, and then adjusted by the synchronous angle of the rotating mechanism, so that the wind direction of the hose flowing into the air guide cylinder is uniformly discharged in a spiral manner, achieving the effect of simple, convenient and efficient uniform venting.
