Solution Overview

Problem

Existing biological data acquisition systems suffer from reduced accuracy due to increased resistance in transmission paths caused by cables and bulkier device sizes when acquiring and transmitting biological data.

Innovation Solution

A connector design that integrates plug contacts and electrode surfaces within a garment, eliminating the need for cables by using conductive members that directly connect to a counter connector, allowing for high-accuracy data acquisition and transmission without additional wiring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a cable is used to transmit biological data from the electrode unit to the external device, then the biological data can be transmitted, but the resistance value in the transmission path increases resulting in lower accuracy

Engineering Contradiction:
Improveaccuracy of biological dataVSAvoidtransmission path structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the cable from the transmission path by implementing direct wireless communication between the electrode unit and external device. The electrode unit includes a communication unit that transmits biological data wirelessly, removing the cable-mediated transmission path that caused resistance and accuracy degradation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a wireless communication unit as an intermediary between the electrode unit and external device, replacing the physical cable connection. This communication unit enables data transmission through electromagnetic waves rather than electrical conduction through a cable, thereby eliminating the resistance issue.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If a connector is connected to the cable to transmit biological data, then data transmission is enabled, but the device size increases

Engineering Contradiction:
Improvebiological data transmission capabilityVSAvoiddevice size
Core Design Contradiction:
Measurement precisionVSVolume of moving object

Solution Approach 1:

The patent merges the communication functionality directly into the electrode unit structure. The communication unit is integrated within the electrode unit housing, combining the data acquisition electrode and data transmission communication capabilities into a single compact device, eliminating the need for separate connectors and cables.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts and removes the external connector and cable components from the system. By implementing wireless communication within the electrode unit itself, the design eliminates the need for separate connectors that would increase device size and complexity.

Inventive Principle:
Principle #2Taking out (Extraction)
