Solution Overview

Problem

Existing vacuum devices face inefficiencies due to the need for multiple interfaces, leading to increased size, cost, and logistical complexity, as well as potential conflicts between control signals from different active interfaces.

Innovation Solution

A device with a switchable connector system that allows the same contacts to be assigned multiple times, featuring a switch between the connector and signal processing units for automatic detection and remote-controlled switching, reducing the number of physical connectors and enabling use of a single connector for various interfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple interfaces are provided in parallel on a device, then the device can support multiple communication standards, but the device size and cost increase due to additional connectors and circuit parts

Engineering Contradiction:
Improveinterface compatibilityVSAvoiddevice size
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple interface types (CAN, RS485, USB) into a single physical connector. The connector has contacts that can be electrically connected to different signal processing units through a switch, allowing one connector to serve multiple interface functions rather than requiring separate connectors for each interface type.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single connector is designed with universal functionality to support multiple communication standards. The same physical connector and contacts can be configured to provide CAN bus, RS485, or USB interfaces depending on the switching configuration, making the connector multi-functional rather than dedicated to a single interface type.

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

4Ease of operation

If discrete connectors are used for each interface type, then each interface can be independently connected, but logistical effort in manufacture and sale increases

Engineering Contradiction:

Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent combines multiple interface types (CAN, RS485, USB) into a single physical connector. The connector has contacts that can be electrically connected to different signal processing units through a switch, allowing one connector to serve multiple interface functions rather than requiring separate connectors for each interface type.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system uses a dynamic switching mechanism that can change the electrical connection configuration based on the detected interface type. The switch can dynamically reconfigure which signal processing unit is connected to which contacts, allowing the same physical connector to adapt its function rather than requiring static, dedicated connectors for each interface type.

Inventive Principle:
Principle #15Dynamics

5Reliability

If control signals from several active interfaces contradict each other, then interface prioritization is needed, but this increases device complexity

Engineering Contradiction:
Improvecontrol signal consistencyVSAvoidinterface management
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system uses a dynamic switching mechanism that can change the electrical connection configuration based on the detected interface type. The switch can dynamically reconfigure which signal processing unit is connected to which contacts, allowing the same physical connector to adapt its function rather than requiring static, dedicated connectors for each interface type.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system employs an allocation unit that detects which interface type is connected and provides feedback to the switching unit. This feedback mechanism allows the system to automatically configure the appropriate interface without requiring complex prioritization logic, as only one interface type is active at a time in each connector.

Inventive Principle:
Principle #23Feedback
