Suction device with function module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction devices have a fixed scope of functions and lack flexibility in adapting to different operational requirements, limiting their versatility in workshop applications.
Innovation Solution
The suction device allows for the replacement of functional modules, enabling the integration of various modules with different functionalities, including electrical, optical, and acoustic functions, through a modular design with a sealing arrangement and accessible module holders, and provides multiple power supply options and communication interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed functional design is used for the suction device, then the device structure is simple and easy to manufacture, but the adaptability to different operational requirements is poor
Solution Approach 1:
The suction device is divided into a base unit and interchangeable functional modules. The control wall is segmented to accommodate different modules, each providing specific functions such as compressed air supply, electrical power, or data communication. This segmentation allows the device to adapt to different operational requirements by simply changing modules rather than redesigning the entire system.
Solution Approach 2:
The suction device is designed with universal interfaces and a standardized module holder that can accommodate multiple types of functional modules. The control wall includes universal connection arrangements that can interface with different module types, enabling a single base unit to perform multiple functions through module interchangeability.
2Ease of operation
If functional modules are made accessible from the outside for easy replacement, then the ease of operation is improved, but the protection from environmental influences is reduced
Solution Approach 1:
The functional modules are nested within a module holder that is integrated into the control wall. The modules can be accessed from the outside by opening a access panel or removing a cover, allowing easy replacement while maintaining protection when installed. The nesting structure provides mechanical protection and environmental sealing when the module is in its installed position.
Solution Approach 2:
A sealing arrangement with flexible sealing elements is provided between the module holder and the functional modules. These flexible seals maintain environmental protection while allowing for thermal expansion and contraction, and accommodate slight manufacturing tolerances. The sealing arrangement protects the electrical connections and internal components from dust, moisture, and other environmental contaminants.
3Adaptability or versatility
If multiple power supply contacts and communication interfaces are provided, then the versatility and functionality are enhanced, but the device complexity increases
Solution Approach 1:
Multiple power supply contacts (switchable, continuous, and automatic supply contacts) and communication interfaces are merged into a single integrated connection arrangement on the control wall. This unified interface structure allows different power supply modes and communication protocols to be accessed through the same physical interface, reducing the number of separate components and simplifying the overall electrical architecture.
