Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple medical devices are arranged around the patient's bed, then medical care can be provided, but safety risks increase due to tangled wires and awkward device placement

Engineering Contradiction:

Improvemedical care capabilityVSAvoidsafety risks

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines multiple medical devices (monitoring equipment, IV pumps, ventilators) into a single integrated mobile cart that moves with the patient. This consolidation eliminates tangled wires and reduces safety hazards while maintaining all necessary medical care capabilities.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated cart serves multiple functions simultaneously - it provides structural support for devices, contains storage compartments for supplies, offers charging stations for electronics, and acts as a mobile workspace for healthcare personnel. This multi-functionality reduces the need for separate devices and improves safety.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If each medical device has its own display panel and control panel, then device functionality is maintained, but space occupation and expense increase

Engineering Contradiction:

Improvedevice functionalityVSAvoidspace occupation

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cart incorporates a universal control system with a single large display panel that can interface with multiple different medical devices through standardized connections. This eliminates the need for separate display panels on each device, reducing space occupation while maintaining full functionality.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The integrated cart acts as an intermediary between the healthcare personnel and multiple medical devices. The universal control interface on the cart communicates with various devices, allowing one operator to control multiple devices without needing individual control panels for each.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If medical devices are transported separately from the patient, then device mobility is achieved, but data loss occurs and reattachment is required

Engineering Contradiction:

Improvedevice mobilityVSAvoiddata loss

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The medical devices are permanently integrated into the mobile cart that travels with the patient. This ensures continuous data collection and transmission without interruption during transport, eliminating data loss risks associated with separating and reattaching devices.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated system maintains continuous operation during patient transport. The devices remain connected to power and data sources throughout the journey, ensuring uninterrupted monitoring and data recording without the need for detachment or reattachment.

Inventive Principle:

Principle #20Continuity of useful action

4Adaptability or versatility

If heavy medical devices are maneuvered in crowded quarters, then care can be provided, but personnel safety is compromised

Engineering Contradiction:

Improvemedical care provisionVSAvoidpersonnel safety

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

Multiple heavy devices are consolidated into a single mobile cart with a unified base structure. This reduces the total weight that personnel must maneuver and eliminates the hazard of tangled wires, improving personnel safety while maintaining comprehensive medical care capability.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An integrated point-of-care system includes a medical monitoring device, a medical care device, a computing system, and a structure. The medical monitoring device monitors patient information for a patient. The medical care device provides medical care to the patient. The computing system receives patient information from the medical monitoring device and transmits control instructions to the medical care device to control the medical care to the patient. The computing system also exchanges data with a central data respository through a communication network. The structure supports the patient, the medical monitoring device, the medical care device, and the computing system. The structure can also transport the patient, the medical monitoring device, the medical care device, and the computing system together.
