Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional ECG electrodes with lead wires are used, then electrical signal transmission is achieved, but patient mobility is restricted and the system becomes cumbersome

Engineering Contradiction:
Improvepatient mobilityVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple electrodes and their associated lead wires into a single integrated chest assembly. The flexible substrate integrates multiple electrodes at predetermined positions with conductive traces that route signals to connection points, eliminating the need for separate lead wires for each electrode and simplifying the overall system while maintaining patient mobility.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The chest assembly is designed as a segmented flexible substrate with electrodes positioned at specific locations. This segmentation allows the assembly to be placed on the patient's chest in a distributed manner while maintaining flexibility and comfort, enabling patient movement without the cumbersome wiring of conventional systems.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If conventional ECG systems with lead wires are used, then signal transmission is achieved, but the lead wires become intertwined making connections difficult

Engineering Contradiction:
Improveconnection easeVSAvoidwire management complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Multiple individual lead wires are merged into a single flexible substrate that contains integrated conductive traces. This consolidation eliminates the problem of intertwined wires, as the substrate provides a unified, organized structure for signal transmission from multiple electrodes to the monitoring device.

Inventive Principle:
Principle #5Merging (Combining)

3Object-affected harmful factors

If conventional ECG systems are used, then monitoring is achieved, but the system interferes with medical imaging due to radiolucency issues

Engineering Contradiction:
Improveimaging interferenceVSAvoidsignal transmission reliability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The conductive traces on the flexible substrate are designed with optimized dimensions and materials to achieve radiolucency. By changing the physical parameters of the conductive elements (such as using thinner traces or radiolucent materials), the system becomes transparent to X-rays and other medical imaging modalities while maintaining adequate electrical conductivity for reliable signal transmission.

Inventive Principle:
Principle #35Parameter changes

4Manufacturing precision

If fully-integrated electrode assemblies are used, then electrode placement accuracy is improved, but the cost increases and flexibility for alternative placement is reduced

Engineering Contradiction:
Improveelectrode placement precisionVSAvoidplacement flexibility
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The chest assembly is designed as a universal platform with electrodes positioned at standard ECG locations on a flexible substrate. This universal design maintains precise electrode placement according to standard protocols while allowing the entire assembly to be adapted to different patient anatomies and monitoring requirements, providing both precision and flexibility.

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