Suction Device Motor Module Access Design for Simplified Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing suction devices require complete dismantling of the suction housing for maintenance tasks such as replacing brushes, making the repair process expensive and complex.
Innovation Solution
A suction device design where the motor module is accessible by opening a cover, allowing for easy removal and replacement without disassembling the entire suction housing, and incorporating air duct sections and seals for efficient airflow management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the suction housing is completely dismantled for maintenance, then the suction motor becomes accessible for repair, but the maintenance process becomes expensive and complex
Solution Approach 1:
The suction housing is segmented into a main housing and a separate cover component. The cover can be independently removed to access the motor module, while the main housing remains intact. This segmentation allows maintenance personnel to access the motor for repair without dismantling the entire suction housing, thereby reducing maintenance complexity and cost while improving accessibility.
2Reliability
If the cover completely closes the assembly opening, then the motor module is well protected, but airflow management becomes more complex
Solution Approach 1:
The cover serves multiple functions simultaneously: it provides protective closure for the assembly opening to shield the motor module, while also incorporating integrated air duct sections that guide airflow to and from the motor. This multi-functionality eliminates the need for separate air duct components, simplifying the overall air duct arrangement while maintaining reliable motor protection.
Solution Approach 2:
The air duct sections are merged with the cover structure rather than being separate components. The cover integrates air duct sections that guide cooling air to the motor and channel suction flow around the motor module. This merging reduces the number of separate parts and simplifies the air duct arrangement while ensuring proper airflow management and motor protection.

Function Achieved in This Case
This design simplifies maintenance and repair by allowing access to the motor module without disassembling the suction housing, reducing costs and improving maintenance efficiency.
Implementation Method 1
a suction motor (12) for generating a suction flow (13)
Implementation Method 2
The seal is used, for example, for fluidic separation of the exhaust duct from the intake duct, for separating cooling air leading to the engine module from the intake flow

AI summary
The device (10) has a suction motor (12) forming a component of a motor module (58) i.e. bypass turbine. A suction housing has an air guiding arrangement (55), which communicates with a motor receiving chamber (54). The motor receiving chamber has a mounting opening (57) at a suction housing-wall (49a) of the suction housing, where the motor module is removed from the motor receiving chamber or inserted into the chamber via the mounting opening. The chamber has a cover (60) for closing the chamber. The suction housing wall is provided as a base wall (49) of a motor housing part (30).
