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

VSEngineering 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

Engineering Contradiction:
Improveadaptability to different operational requirementsVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improveease of module replacementVSAvoidprotection from environmental influences
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

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.

Inventive Principle:
Principle #7Nested doll (Nesting)

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.

Inventive Principle:
Principle #30Flexible shells and thin films

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

Engineering Contradiction:
Improvefunctionality with multiple power supply optionsVSAvoidelectrical connection arrangement
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)
