Modular Blower Casing With Selective Fixing Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blower devices are costly to reconfigure for attachment to objects with varying shapes due to the need for multiple molds and increased manufacturing costs when changing the position of fixing attaching legs.
Innovation Solution
A blower device with a modular design featuring a blower casing and a separate fixing member with multiple axial projecting portions or grooves, allowing for flexible attachment to various surfaces by engaging these features, reducing the need for mold changes and enabling low-cost adaptation to different shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the fixing attaching leg position is changed to attach to different surfaces, then the adaptability to various shapes is improved, but the manufacturing cost increases due to mold changes
Solution Approach 1:
The blower lower casing is designed with multiple fixing attaching legs at different positions, allowing a single standardized casing to be attached to various surfaces and shapes. This universal design eliminates the need for multiple specialized molds, reducing manufacturing costs while maintaining adaptability to different installation scenarios
Solution Approach 2:
The fixing attaching legs are designed as separate, modular features that can be independently positioned on the blower lower casing. This segmentation allows the casing to be standardized while the fixing legs provide the necessary variations for different attachment positions, separating the standardized body from the adaptable fixing features

AI summary
It is possible to provide a blower device which can be attached to a target having various kinds of shapes at low cost. A blower device 1 including a blower casing 2 having a structure in which an impeller 7 is housed in a primary casing 5 and a secondary casing 6, and then the casings are assembled together, and fixing member 3 which is attached on an outer circumference of the blower casing 2 and which is to fix the blower device 1 to an attachment target, in which the fixing member 3 can be selectively attached among the attachment positions on the blower casing 2.
