Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The commissioning process for pneumatic actuator devices is complex and prone to errors due to mismatched display steps and current control module states, making it difficult for users to perform the necessary steps correctly.

Innovation Solution

A method where the control module state is transmitted to a graphical display device via a communication link, ensuring that the displayed commissioning steps align with the current state of the control module, using a tablet computer or mobile phone as the graphical display device, and a control module with a valve device and control unit for open-loop or closed-loop control to manage compressed air.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If commissioning steps are displayed without real-time state synchronization, then the display device can show all commissioning steps, but the displayed steps may not match the current control module state, causing user confusion and errors

Engineering Contradiction:

Improveaccuracy of commissioning guidanceVSAvoidcomplexity of commissioning process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The control module continuously transmits its current state to the display device, which then filters and displays only the commissioning steps relevant to the current state. This feedback mechanism ensures that the displayed commissioning steps always match the actual control module state, preventing user confusion and errors while maintaining a simple commissioning process.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The display device dynamically adapts its content based on the real-time state of the control module. Instead of showing a static list of all commissioning steps, the system dynamically filters and presents only the steps that are currently applicable, making the commissioning process more reliable and easier to follow.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If all commissioning steps are displayed at once, then users have complete information, but users may be overwhelmed and make errors due to information overload

Engineering Contradiction:

Improveease of commissioningVSAvoidloss of context about current state

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The commissioning steps are segmented and filtered based on the current control module state. Instead of presenting all commissioning steps at once, the display device shows only the relevant steps for the current state, making the commissioning process easier to follow without losing important information about what needs to be done next.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary filtering of commissioning steps based on the current state before presenting them to the user. This preliminary action ensures that users receive only the information they need at the current stage, preventing information overload while maintaining complete awareness of the commissioning progress.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method for commissioning a pneumatic actuator device, which includes a pneumatic drive cylinder and a pneumatic control module mounted on the pneumatic drive cylinder, wherein a plurality of commissioning steps to be carried out for commissioning are displayed by means of a graphical display device separate from the control module, the graphical display device in particular being a tablet computer or a mobile telephone, and wherein a control module state is being transmitted from the control module to the display device via a communication link between the control module and the display device, and the commissioning steps are being displayed taking into account the transmitted control module state.
