Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blower housing structures face challenges with difficult assembly, insufficient structural strength, easy vibration, and increased noise due to resonance, leading to cumbersome installation, high manufacturing costs, and reduced service life.
Innovation Solution
A blower housing assembly structure featuring a locking base and casing covers made from aluminum die casting, with a U-shaped cross-section and engaging pipe sections to form an exhaust vent, providing enhanced stability and alignment for improved assembly and vibration resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the housing is formed by pivoting and locking multiple metal sheets, then the housing can be assembled from separate components, but the structural strength is insufficient and the assembly is cumbersome
Solution Approach 1:
The patent merges multiple separate metal sheets into a single integrated housing structure. The housing body, side covers, and partition are formed as one unified piece through die-casting, eliminating the need for separate pivoting and locking operations. This integration directly resolves the contradiction by maintaining manufacturing flexibility through modular design while dramatically improving structural strength.
2Ease of manufacture
If multiple metal sheets are connected with pivots and locking parts, then the housing can be assembled, but additional manufacturing cost is incurred
Solution Approach 1:
The patent combines multiple components into a single die-cast housing structure, eliminating pivots, locking parts, and other connectors. The integrated design maintains assembly capability through simple installation while removing the complexity and cost associated with multiple separate parts and their connecting mechanisms.
3Ease of manufacture
If the housing is formed by assembling multiple metal sheets, then the components can be manufactured separately, but the assembly is cumbersome and time-consuming
Solution Approach 1:
The patent merges separate metal sheet components into a single integrated housing that can be manufactured through die-casting. This approach maintains the benefit of specialized component manufacturing while dramatically improving assembly efficiency by reducing the housing to a single pre-assembled unit, eliminating time-consuming assembly operations.
4Ease of manufacture
If multiple metal sheets are used to form the housing, then the housing can be constructed from flat components, but the connection is poor and vibration occurs easily
Solution Approach 1:
The patent combines multiple separately fabricated metal sheets into a single die-cast housing structure. This integration maintains the ease of manufacturing through standardized die-casting processes while eliminating connection instability and vibration issues by removing all joints and connections between separate metal sheets.

AI summary
A blower housing assembly structure includes a locking base formed by aluminum die casting and two opposite casing covers disposed on both sides of the locking base respectively. The locking base has two opposite side connecting plates, each having a connection part formed at the top of the side connecting plate, and a side of each casing cover has an intake vent, and the two casing covers have two opposite half-extended pipe sections extending from the edges of the locking base connection part respectively, so that the half-extended pipe sections of the two casing covers are engaged to form an exhaust vent of a housing. This invention has the advantages of simple structure, easy assembling, effective alignment and high stability and the effects of preventing damages by vibration and reducing the noise during operation.
