Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional induced draft fan adapters have complex assemblies, high manufacturing costs, and limited universality due to fixed connection angles and lengths, leading to troublesome installation and poor adaptability to different loads.
Innovation Solution
The adapter comprises an installation section, a transition section with flexible foldable parts, and an exit section, featuring a water storage cavity, drain holes, and adjustable connection angles and lengths, allowing for easy installation and adaptation to various loads through a combination of hard and soft materials, including steel rims for enhanced rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adapter includes many parts with fixed connection angles and lengths, then the connection between the adapter and outer pipe is stable, but the assembly becomes troublesome and manufacturing cost increases
Solution Approach 1:
The adapter is divided into three main sections: installation section (with inner ring, outer ring, and connection plate), transition section (with flexible pipe containing foldable parts), and exit section (with connection and expansion sections). This segmentation allows each part to perform its specific function while reducing overall complexity.
Solution Approach 2:
The transition section incorporates a flexible pipe with foldable parts that can dynamically adjust the connection angle and length between the installation section and exit section. This dynamic capability replaces fixed rigid connections, reducing the number of parts needed while maintaining connection stability.
2Manufacturing precision
If the adapter has fixed connection angles and lengths, then the manufacturing precision is easier to control, but the universality and adaptability to different loads deteriorates
Solution Approach 1:
The flexible pipe with foldable parts in the transition section enables dynamic adjustment of connection angles and lengths, allowing the adapter to adapt to different installation requirements and load conditions while maintaining manufacturing precision through controlled flexibility.
Solution Approach 2:
The adapter allows changes in geometric parameters (connection angle and length) through the foldable parts mechanism, enabling the same adapter structure to accommodate various installation scenarios without requiring multiple specialized components.
3Reliability
If multiple components are used in the adapter, then the connection between parts is more reliable, but the installation process becomes more troublesome
Solution Approach 1:
The inner ring, connection plate, and outer ring are connected one by one to form an integrated water storage cavity structure, reducing the number of separate components while maintaining connection reliability through the unified cavity design.
Solution Approach 2:
The foldable parts in the flexible pipe are pre-configured to enable easy adjustment during installation, allowing installers to achieve the desired connection angle and length without complex assembly steps or specialized tools.
4Ease of manufacture
If the adapter structure is simplified with fewer parts, then the manufacturing cost is reduced, but the ability to discharge condensed water and adapt to different diameters may deteriorate
Solution Approach 1:
The flexible pipe with foldable parts serves multiple functions: it provides flexibility for angle and length adjustment, maintains structural integrity, and enables adaptation to different air duct diameters, replacing the need for multiple specialized components.
Solution Approach 2:
The flexible pipe incorporates foldable parts that can bend and flex to accommodate different installation geometries and duct diameters, providing adaptability without requiring additional rigid components or complex assembly structures.

AI summary
An adapter for an induced draft fan includes an installation section; a transition section; and an exit section. The installation section and the exit section are disposed on two ends of the transition section, respectively. The installation section includes an inner ring, an outer ring, a connection plate, and a water storage cavity. The outer ring includes a first end and a second end; the first end of the outer ring is connected to the transition section; the second end of the outer ring is connected to a first end of the inner ring via the connection plate. The inner ring, the connection plate, and the outer ring are connected one by one to form the water storage cavity. The outer ring includes at least one drain hole communicating with the water storage cavity; and a drain pipe is disposed on the outer ring.
