Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If therapy-relevant patient data is entered at one infusion pump, then data is automatically transmitted to all other infusion pumps in the network, but data integrity and consistency become difficult to ensure when patients switch between pumps

Engineering Contradiction:
Improvedata synchronization efficiencyVSAvoiddata integrity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system implements a feedback mechanism where the central server continuously monitors data synchronization status across all infusion pumps and sends correction signals to ensure consistency. When data is entered at one pump, the server verifies reception and integrity at all other pumps, creating a closed-loop control system that maintains data reliability while enabling efficient network-wide synchronization.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

A central server acts as an intermediary between infusion pumps in the network. Instead of direct peer-to-peer communication that may lead to data inconsistencies, all data transmission routes through the central server which validates, standardizes, and distributes data uniformly to all pumps, ensuring data integrity while maintaining synchronization efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If multiple infusion pumps are connected in a network for seamless patient switching, then therapy efficiency is enhanced, but system complexity increases

Engineering Contradiction:
Improvetherapy efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges multiple infusion pumps into a unified networked system with shared data infrastructure and central server management. By combining individual pumps into a coordinated network, the system achieves seamless patient transitions and improved therapy efficiency while the central server absorbs much of the computational and coordination complexity, keeping individual pump devices relatively simple.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The central server provides universal functionality for the entire network, handling data management, synchronization, and coordination tasks that would otherwise require complex individual pump capabilities. This multi-functional approach allows multiple pumps to work together efficiently while maintaining simplicity at the device level.

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

3Ease of operation

If therapy-relevant patient data is synchronized across all infusion pumps, then data accessibility is improved, but data transmission time and network load increase

Engineering Contradiction:
Improvedata accessibilityVSAvoiddata transmission time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-synchronizing common patient data (such as demographic information and therapy parameters) across all infusion pumps before they are needed. This advance preparation ensures that when a patient switches between pumps, the data is already available locally, eliminating transmission delays and improving accessibility without increasing real-time network load.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent segments data into different categories (frequently accessed vs. rarely accessed, critical vs. non-critical) and transmits them with different priorities and frequencies. Critical data is synchronized immediately and kept in local memory for instant access, while less critical data is updated periodically, reducing overall network load and transmission time while maintaining data accessibility.

Inventive Principle:
Principle #1Segmentation
