Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recirculation switches for air extraction ducts are time-consuming to assemble due to their complex screwing mechanism and require multiple identical parts, which complicates installation and adaptation to different duct widths.
Innovation Solution
A recirculation switch constructed from two plug-in components with optional latching, featuring a simplified assembly process and adaptable width adjustment through a single attachment element, allowing for quicker installation and compatibility with various duct sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional screwing mechanism is used to assemble recirculation switch components, then structural integrity is achieved, but assembly time and complexity increase significantly
Solution Approach 1:
The patent combines multiple screwing operations into a single plug-in connection mechanism. Two structurally identical components are designed with complementary plug-in connections that engage simultaneously when the components are inserted together, eliminating the need for multiple separate screwing operations and significantly reducing assembly time while maintaining structural integrity
Solution Approach 2:
The patent replaces the traditional screwing mechanism with a plug-in connection system. Instead of requiring threaded fasteners and torque application, the components feature interlocking plug-in interfaces that provide both connection and alignment through simple insertion, substituting a complex mechanical fastening system with a simpler engagement mechanism
2Adaptability or versatility
If multiple identical parts are used to construct recirculation switch, then assembly flexibility is improved, but device complexity and installation time increase
Solution Approach 1:
The patent designs two structurally identical components that can serve multiple functions. Each component can be used in different positions (first position or second position) and can be interchanged with the other, providing assembly flexibility and adaptability to different installation configurations without requiring multiple different part types
Solution Approach 2:
The recirculation switch is divided into two separate but identical components, each capable of independent manufacturing and assembly. This segmentation allows for modular construction where the components can be assembled in different sequences or configurations, providing flexibility while keeping each individual component simple
3Ease of manufacture
If fixed width design is used for recirculation switch, then manufacturing simplicity is maintained, but adaptability to different duct widths is reduced
Solution Approach 1:
The patent enables the recirculation switch width to be dynamically adjusted by selecting different combinations of the identical components. By varying the number of components or their arrangement in the assembly, the overall width can be adapted to match different air discharge duct widths while maintaining the same simple component design for manufacturing
