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

VSEngineering 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

Engineering Contradiction:
Improveflexibility in constructionVSAvoidproduction complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improvestructural stabilityVSAvoidplacement precision of spacer elements
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

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.

Inventive Principle:
Principle #5Merging (Combining)

3Length of moving object

If the slot diffuser length is increased, then air flow capacity is improved, but structural strength decreases due to bending

Engineering Contradiction:
Improvediffuser lengthVSAvoidstructural strength
Core Design Contradiction:
Length of moving objectVSStrength

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #40Composite materials

4Reliability

If deflector holders are added at regular intervals, then deflector anchoring is improved, but air flow surface area is reduced

Engineering Contradiction:
Improvedeflector anchoringVSAvoidair flow surface area
Core Design Contradiction:
ReliabilityVSArea of stationary object

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.

Inventive Principle:
Principle #5Merging (Combining)
