Slot diffuser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current slot diffusers are labor-intensive to produce, require specialized equipment, and have limitations in length and flexibility due to the use of separate spacer elements, leading to potential deviations and deformation, which affect air flow efficiency and increase energy costs.
Innovation Solution
A continuous slot diffuser design with an elongated beam-shaped frame and integrated deflectors, where side walls are connected via end and center bridges, eliminating the need for spacer elements, and using holding-down organs to anchor deflectors and enhance structural strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If slot diffusers are constructed from separate side walls connected by spacer elements, then flexibility in construction is improved, but labor intensity and production complexity increase
Solution Approach 1:
The patent merges the side walls and spacer elements into a single integrated profile structure. The profile contains multiple chambers that form side walls and integrated holding-down organs that replace separate spacer elements, eliminating the need for assembly operations and reducing production complexity while maintaining construction flexibility.
2Stability of the object's composition
If multiple spacer elements are used to connect side walls, then structural stability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The holding-down organs are integrated into the profile structure itself rather than being separate components. This eliminates the need for precise placement of separate spacer elements, as the holding-down organs are formed as part of the extruded profile, reducing manufacturing precision requirements while maintaining structural stability.
3Length of moving object
If the slot diffuser length is increased, then air flow capacity is improved, but structural strength decreases due to bending
Solution Approach 1:
The profile is divided into multiple chambers (first, second, third chambers) that act as structural ribs. These chambers provide internal support that prevents bending and maintains structural strength in longer diffuser configurations, enabling increased length without sacrificing strength.
Solution Approach 2:
The profile utilizes a composite structure with multiple chambers and integrated holding-down organs formed from the same material. This composite design provides both the length needed for air flow capacity and the structural strength through the multi-chamber configuration that resists bending.
4Reliability
If deflector holders are added at regular intervals, then deflector anchoring is improved, but air flow surface area is reduced
Solution Approach 1:
The holding-down organs serve dual functions: they provide structural support for the side walls and simultaneously anchor the deflectors. By integrating these functions into a single element, the design avoids adding separate deflector holders that would block air flow, maintaining surface area while ensuring reliable deflector anchoring.
