Incorporating a layer of magnetic material in the conductive layer, allowing for a removable magnetic connection between the patient contact and transmission portions, which ensures secure signal transmission without welding and enables easy attachment and detachment without skin pressure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the button system is used to connect the transmission portion with the patient contact portion, then the connection reliability is improved, but the production complexity increases due to requiring an intermediate crimping station

Engineering Contradiction:

Improveconnection reliabilityVSAvoidproduction complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical crimping system with a magnetic connection system. The transmission portion includes a magnetic element that attracts to a magnetic layer in the patient contact portion, eliminating the need for mechanical crimping stations and complex assembly equipment while maintaining secure electrical connection.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts the connection function from the complex mechanical button system and isolates it as a separate magnetic attraction mechanism. This allows the patient contact portion to be produced independently without requiring intermediate crimping operations, simplifying the overall production process.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If the button system is used for connection, then the connection stability is improved, but the skin trauma risk increases due to required pressure action

Engineering Contradiction:
