Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If wireless communication is established between medical accessories and blood treatment apparatus, then data transmission efficiency is improved, but the complexity of setting up wireless networks increases

Engineering Contradiction:

Improvedata transmission efficiencyVSAvoidwireless network setup complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-configuring wireless communication parameters and authentication data into the blood treatment apparatus before the actual wireless connection is needed. This allows the apparatus to quickly establish wireless connections with accessories without requiring complex real-time network setup, thereby improving data transmission efficiency while minimizing setup complexity.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If configuration data is pre-loaded into the blood treatment apparatus, then wireless communication setup is simplified, but the manufacturing complexity increases

Engineering Contradiction:

Improvewireless communication setupVSAvoidmanufacturing complexity

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The patent implements self-service by enabling the blood treatment apparatus to automatically generate, store, and manage its own wireless communication configuration data and authentication credentials. This self-configuring capability simplifies the wireless setup process for users while avoiding the need for complex manual preconfiguration during manufacturing, thus resolving the contradiction between ease of operation and ease of manufacture.

Inventive Principle:

Principle #25Self-service

3Quantity of substance

If a single data acquisition unit is used with multiple devices, then equipment costs are reduced, but the risk of misconfiguration increases

Engineering Contradiction:

Improvenumber of data acquisition unitsVSAvoidconfiguration accuracy

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The patent applies feedback by implementing automatic configuration verification and device identification mechanisms. When a data acquisition unit connects to a blood treatment apparatus, the system automatically verifies the apparatus identity, checks configuration compatibility, and provides feedback to ensure correct pairing. This feedback loop maintains high configuration accuracy even when a single data acquisition unit is reused across multiple devices, thereby reducing equipment costs without compromising reliability.

Inventive Principle:

Principle #23Feedback
