Blower Volute Embedded Cover Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blower volutes have complex and costly installation structures due to fixed interfaces between the bottom cover and cover body, requiring multiple specifications to accommodate different installation and steering positions, leading to high production and management costs.
Innovation Solution
A blower design featuring a blower volute with a cover body and bottom cover that are embedded and welded or stuck together, incorporating installation parts, a convex ring body, reinforcing ribs, and a fan wheel with a double blade structure, which simplifies the connection, enhances air intake, and includes drainage features for efficient water removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the bottom cover and cover body are connected using screws or bolts, then the connection is secure, but the installation structure becomes complex and cost increases
Solution Approach 1:
The patent merges the bottom cover and cover body into an integrated structure where the bottom cover is embedded directly into the cover body without separate fastening components. This eliminates screws or bolts while maintaining connection strength through the embedded design, thereby reducing structural complexity and installation cost.
Solution Approach 2:
The bottom cover is nested within the cover body through an embedded connection method. The bottom cover fits into a recess or cavity in the cover body, creating a nested structure that provides secure connection without requiring external fasteners, thus simplifying the overall installation structure.
2Stability of the object's composition
If the interface between bottom cover and cover body is fixed, then connection is stable, but the bottom cover loses universality and requires multiple specifications
Solution Approach 1:
The embedded connection design creates a universal bottom cover that can be adapted to different cover body configurations. By embedding the bottom cover into the cover body rather than using fixed external interfaces, a single bottom cover design can serve multiple installation positions and steering requirements, enhancing versatility while maintaining stable connection.
Solution Approach 2:
The patent introduces adjustable or adaptable features in the embedded connection that allow the bottom cover to accommodate different positions and orientations. This dynamic capability enables the same bottom cover to be used in various configurations without requiring multiple fixed-specification covers, thus improving universality while preserving connection stability.
3Adaptability or versatility
If different specifications of bottom covers are produced to meet different installation requirements, then customer requirements are met, but production and management cost increases
Solution Approach 1:
The embedded connection design enables a universal bottom cover that can satisfy multiple installation requirements through its adaptable embedding method. This eliminates the need to produce multiple bottom cover specifications for different customers' requirements, thereby reducing production complexity and management costs while maintaining full adaptability to various installation positions and steering configurations.
