Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wired contact leads are used for ECG testing, then reliable electrical signal transmission is achieved, but lead placement accuracy deteriorates and setup time increases

Engineering Contradiction:

Improvesignal transmission reliabilityVSAvoidlead placement accuracy

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The patent replaces the mechanical wired connection system with a wireless communication system. The ECG leads use wireless transceivers to transmit electrical signals from the patient's body to the ECG machine, eliminating physical wire connections. This substitution resolves the contradiction by removing the mechanical constraints that caused placement errors while maintaining reliable signal transmission through wireless communication protocols.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces wireless communication technology as an intermediary between the ECG leads and the main ECG machine. Instead of direct wired connections, signals are transmitted through wireless intermediaries (radio frequency communication), which eliminates the physical entanglement and placement difficulties while maintaining signal integrity and reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Duration of action of stationary object

If wired contact leads are used for ECG testing, then continuous signal monitoring is achieved, but procedural interference increases and operator speed decreases

Engineering Contradiction:

Improvecontinuous monitoring capabilityVSAvoidoperator speed

Core Design Contradiction:

Duration of action of stationary objectVSProductivity

Solution Approach 1:

The wireless system replaces mechanical wire connections with electromagnetic signal transmission. This eliminates the physical wires that interfered with medical procedures and slowed operators. The continuous monitoring capability is maintained through persistent wireless communication, while operator speed improves due to the elimination of wire management tasks.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Stability of the object's composition

If wired contact leads are used for ECG testing, then stable electrical connection is achieved, but device complexity increases due to wire management

Engineering Contradiction:

Improveelectrical connection stabilityVSAvoidwire management complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent replaces the complex mechanical wire management system with a streamlined wireless communication system. The stability of electrical connections is maintained through reliable wireless signal transmission, while device complexity is reduced by eliminating the need for physical wire routing, connection management, and tangle prevention mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Loss of time

If wireless contact leads are used for ECG testing, then setup time is reduced and procedural interference is eliminated, but identification of individual leads becomes more difficult

Engineering Contradiction:

Improvesetup timeVSAvoidlead identification difficulty

Core Design Contradiction:

Loss of timeVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies color coding to the wireless ECG leads to facilitate easy identification. Each lead is assigned a distinct color or color pattern, allowing operators to quickly distinguish between different leads (e.g., right arm, left arm, right leg, left leg, precordial leads) without the confusion of tangled wires or similar-looking connectors.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent uses asymmetric design features on the wireless leads, such as unique shapes, sizes, or positioning of components on each lead. This asymmetry creates distinctive visual and physical characteristics for each lead type, making identification intuitive and reducing errors during placement.

Inventive Principle:

Principle #4Asymmetry
