Solution Overview

Problem

Current pump apparatus error management requires users to manually search through instruction manuals and communicate with service centers, leading to delays and potential misinterpretation of error messages, especially due to geographical and language barriers, and often necessitates shutting down the pump, causing lost error messages.

Innovation Solution

A pump apparatus with a user interface that includes a display unit and input means to provide error messages and remedy instructions, featuring a diagnostic unit connected to sensors that identifies faults, executes error modes, and offers language-selectable error guidance, allowing users to select and execute error remedy instructions efficiently, with the option to reset and confirm actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If users manually search through instruction manuals to find error remedy instructions, then comprehensive error information is available, but time consumption and complexity increase significantly

Engineering Contradiction:
Improveerror remedy instruction accessibilityVSAvoidtime to locate remedy instruction
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent extracts the essential error remedy information from the comprehensive instruction manual and presents it directly on the device display. When an error occurs, the system automatically retrieves and displays the specific remedy instruction corresponding to the error code, eliminating the need for users to search through numerous pages of the manual.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates a digital copy of the error remedy information that can be displayed directly on the device. Instead of requiring users to consult physical manuals, the system stores and displays copied versions of the necessary instructional content on the device's display interface.

Inventive Principle:
Principle #26Copying

2Ease of operation

If users consult printed instruction manuals for error remedies, then detailed guidance is provided, but language barriers and geographical limitations reduce effectiveness

Engineering Contradiction:
Improveerror resolution processVSAvoidlanguage and location adaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements language as a selectable parameter in the system. Users can choose their preferred language through the interface, and the error messages and remedy instructions are displayed in the selected language. This transforms the static, language-bound manual into a dynamic, multi-language capable system.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If users shut down the pump apparatus to resolve errors, then safety is ensured, but error messages may be lost and operation is interrupted

Engineering Contradiction:
Improvesafe error resolutionVSAvoiderror message retention
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent performs preliminary action by displaying the error message and remedy instruction on the device display before the user shuts down the apparatus. This ensures that the error information is captured and presented to the user while the system is still running, allowing them to resolve the issue without complete shutdown or with minimal interruption.

Inventive Principle:
Principle #10Preliminary action
